Function Of The Cardiovascular System

Function Of The Cardiovascular System In this assessment i will be writing about that structure and function of the cardiovascular system. The cardiovascular system includes the heart, blood vessels, blood and the lymphatic system. The heart is an organ that is a none fatiguing muscle; it passes amino acids and other key nutrients. It transports other gases like oxygen and hormones. It carries waste products and then they are removed from the body, as well as that it transports de oxygenated gases and this is then expired. There are 5 functions of the heart these functions are: transporting of nutrients, delivery of oxygen to working muscles, removal of waste produce, distributing key hormones and to transport De-oxygenated blood to the lungs. -Transporting of nutrients this is one of the important functions of the heart because it has to deliver nutrients to our working muscles. These nutrients are carried via plasma and plasma is in our blood. This is important because the muscles need to be supplied with energy and this energy is called glucose. This is needed for sports with short explosive movements like basketball. Glucose is also delivered with oxygen, and this slows that rate of the muscle fatiguing. -Removal of waste produce The Cardiovascular system removes waste products such as Carbon Dioxide (CO2) and Lactic Acid from the muscle tissues. If the lactic acid doesnt get removed from your muscles then you will feel stiff and sore the next day and your muscles will not be able to perform as well as they did the day before. -Distributing hormones Endocrine system is where the hormones are produced it is then transported in blood. This is made from the bone marrow witch is found in the centre of bones. Plasma is made up of about 53-56% blood; it contains proteins, carbon dioxide, ions and blood cells. This is important when it comes to sport because it prepares us for sport and adrenaline is produced, when adrenaline is released the athletes heart rate will increase and will get them ready for the sport. A sporting example in basketball would be at the start of an important game when the players are anxious of nervous. Transport De-oxygenated blood to the lungs the cardiovascular system also transports de-oxygenated blood to the lung and it is then expired. The pathway of this is as followed: Blood enters the heart via the superior vena cava, flows into the right ventricle passing though the tricuspid valve. As soon as the right ventricle is full this valve then snaps shut to stop back flow , it is important that there is no back flow because if oxygenated and de-oxygenate blood was to mix then the working muscles would not be getting any oxygen and would fatigue. Also it would starve the brain and you would pass out. Following on with the journey, the right ventricle it then flows via the pulmonary artery (this is the only artery that carries de oxygenated blood) the blood is then defused in the lungs and becomes oxygenated. This is a very important function as out muscles need as much oxygen as possible to function at their optical level. -Blood Red blood cells theses are also called Erythrocytes these are used to carry oxygen around the body by Haemoglobin. They also transport other nutrients round our body that it requires. They take up oxygen in the lungs or gills and release it while squeezing through the bodys capillaries. These cells cytoplasm is rich in haemoglobin, an iron-containing bimolecular that can bind oxygen and is responsible for the bloods red colour. The Cardiovascular system carries white blood cells also called leukocytes, around our body which provides immunity from invading organisms. By having white blood cells in our body this stops us becoming seriously ill from illnesses, for example leukaemia, flu or just a cold .As our body is able to fight against it keeping the flu to a minimum. -platelets Platelets are sticky fragments of cells. Like blood they are produced in the bone marrow. The function of platelets is to control bleeding and to form scabs. Thrombocytes do this by sticking together in cuts making tiny fibres grow. Our red cells get trapped within the individual fibres and form a blood clot. This blood clot then turns into a scab. -Heart Important parts of the Heart which help the cardiovascular system work. the heart has a left and right side, separated by a wall of muscle called the septum. Blood from your body enters the right side of your heart through veins. The blood is dark because it has given all its oxygen to your body. The right side of the heart pumps the blood through the pulmonary artery to your lungs to pick up oxygen. After travelling through the lungs, the blood turns bright red because it is rich in oxygen. The oxygen-rich blood then returns to the left side of your heart and is pumped out to your body through the large artery called the aorta. The cardiovascular system can be affected with intense training. This would have a positive affect on training. Endurance training would increase the left ventricle wall. This is called hypertrophied. Basically this means that the heat does not have to work as hard to pump the blood around the heart because it is stronger, but it still pumps the right amount of oxygen and blood to the working muscles. If you were to do this training then your resting heart rate would be decreased. But over time if you was to stop training then your heart would reduce in size over time. But this could be bad if you were to do too much intense training because the heart would get to bug and your resting heart rate would be too low, if it was under 30BPM then it could be life threatening this is called hypertrophic cardiomypathy. TE-Lymphatic system diagram.svg Part of the immune system is the lymphatic system which is made up of a network of conduits that carry a clear fluid called lymph (from Latin lympha water). It also includes the lymphoid tissue and lymphatic vessels through which the lymph travels in a one-way system in which lymph flows only toward the heart. Lymphoid tissue is found in many organs, particularly the lymph nodes, and in the lymphoid follicles associated with the digestive system such as the tonsils. The system also includes all the structures dedicated to the circulation and production of lymphocytes, which includes the spleen, thymus, bone marrow and the lymphoid tissue associated with the digestive system. http://en.wikipedia.org/wiki/Lymphatic_system Another function of the cardiovascular system is the regulation of body temperature, this is controlled by homeostasis. Homeostasis is the state of inner balance and stability maintained by the human body despite constant changes in the external environment. It also works by filtering the blood and removing a carefully regulated amount of water and wastes to the lungs working together with the heart, blood vessels, and blood to distribute oxygen throughout the body and remove wastes. It includes monitoring the water balance in the body, controlling blood sugar, body temperature control and monitoring of urea in the blood. All these processes are controlled by mechanisms such as sensors that detect the factor value. Another mechanism is the correction mechanism involving a negative feedback. Control of body temperature is controlled constriction and dilation of blood vessels, which is demonstrated in the body through vasoconstriction and vasodilation. Vasodilation involves the dilation of the blood vessels to release excess heat therefore blood will flow quickly/faster to the muscles. The vessels are widening in diameter so more blood can flow through. Vasoconstriction involves the constriction of the blood vessels to keep in any heat therefore blood will flow slowly to the muscles. The vessels are reducing in diameter so less blood can flow through.

I wish I could say I was proud of my generation, but lets face it: the media aren’t far wrong

The common perception of teenagers today is soiled by images of alcohol, drugs, hoodies, crime, disobedience, violence and unintelligence. Most teenagers would counter this with outrage and blame these demeaning interpretations on a small minority and stereotyping in the media; but I am here to say that we bring it upon ourselves to have such a reputation. I wish I could say I was proud of my generation, but let's face it: the media aren't far wrong. Having been amongst it for many years now, I can safely say that we are a generation of deadbeat, attention seeking, conformist, moaners. Thriving from a lack of discipline, we spend our days free of any common manner: loitering around in a constant sulk, yawning without covering our mouths, wearing caps indoors as if it's perfectly acceptable. A rare occasion: when â€Å"please† and â€Å"thank you† is used in an exchange, when a smile is seen to disprove any hostility, or when vocal responses outside of a pathetic mumble are explored. That'll be the day. These are all rules which would appear obvious to the older generation, however in my generation, they are disregarded and branded as old-fashioned. â€Å"Who needs standards anyway? Get with the times, I'm not hurting anyone!† we plea, as an excuse to act like slobs and walk around in vests eating pasties in the streets before throwing the wrapping on the floor and wiping our hands on our thighs. Not only is there a decline in manner, but there is a decline in language. It pains me to watch the Americanisation of British English slowly materialise, and this is more prominent than ever amongst teenagers. Every sentence is littered with the word â€Å"like†, and words such as â€Å"whatever† and â€Å"dunno† are common responses. Swearing and slang is used to show some sort of rebellion against manner or social inclusion amongst friends†¦ or should I say â€Å"mates†. And now – with the increased reliance on mobile phones – text speak is diseasing the English language with its pointless abbreviations. TBH, IDK what's wrong with speaking properly. Another embarrassing element of teenage culture is the underage consumption of alcohol, which is now a growing problem amongst teenagers. Flashback 20 years ago and teenagers would be lucky to have a sip of eggnog during Christmas; now, we're out â€Å"on the lash† almost every weekend. Going out with the general motive of â€Å"having a laugh†, stumbling past careless doormen into dingy clubs, awkwardly mingling with people twice their age, and eventually passing out at 4AM without any care or dignity about them and a little nudge towards liver disease. But why is there the need to drink underage? The fact is that as teenagers, we are resistant to accept our adolescence, we all strive for maturity, all we want is to fit in with the grown-ups. We try and convert our undeveloped minds to fit that of an adult's by indulging in such substances as coffee, alcohol and maybe (for the extra-mature kids) drugs. We buy lottery tickets the second we turn 16, learn to drive the second we turn 17, and get plastered the second we turn 18. Oh, how mature. While the teenagers race towards maturity, the parents try their hands at being young and hip just once, and are slated beyond belief. We speedily climb the ladder of maturity, whilst our parents wait at the top fuelling us with food, money and too much damn freedom. Aside from acting mature, teenagers have other means of flaunting their independence, such as fashion. A teenager's sense of fashion is something which often confuses the older generation, and no wonder. Teenagers are now walking around with gaping holes in their ear lobes, absurd hair colours and pieces of metal skewered through their face, it's like we've regressed to the days of the freak show. The reason for this is that we see fashion as a way of self-expression, it's a contest to see who can have the most unique look, and this often leads to a rather outlandish outcome. However, this is no excuse for wearing sunglasses and caps indoors or girls caking their faces in make-up and wearing revealing outfits. The current state of fashion is a gargantuan mess: people trying to stand out and people trying to fit in with those who stand out; that is the general idea. And the result: a cacophony of cries for attention. Something that is corresponding amidst most teenagers is the constant need to complain, it's almost as if we enjoy it. Even if we were living the perfect life, we'd probably whine about how it's â€Å"too perfect†. Facebook is used as a platform for voicing such dire grievances as â€Å"EASTENDERS CANSELLD 4 THA FOOTIE! OMG!† or â€Å"ME MAM BURNT ME CHIKEN NUGETS!† – freedom of speech at its best. Money is an aspect which often spurs complaints: we complain about our lack of money, so we get a job and complain about how bad that is, then we earn money and spend it on trivial things. Then the cycle repeats, over and over and over. Maybe there's nothing wrong with us complaining, I mean, it's not like there are people worse off or anything. It's not easy wielding such a pretentious outlook at my age, it's a constant struggle, withstanding the strain of influence inflicted by fellow teenagers. Alas, few are those who choose a country walk over a pub crawl, Tchaikovsky over Tupac, broadsheets over booze. â€Å"Stuff the rules, we just wanna have fun!† Will a game of chess and some homemade shortbread entice you? Thought not.

Vaccinating Children And Their Effects On Children

Vaccinating is the most crucial and effective way to keep people healthy. It protects everyone from dangerous disease, but in some religion they don’t allow. People tend to believe that vaccines can give their kids autism, but it’s a misconception. Studies have shown that there is no link between vaccines and autism. â€Å"Some people worry that receiving too many vaccines early in life can overwhelm a baby s immune system and that this might somehow lead to autism† (Evidence Shows). Although some children do have allergic reaction from vaccines. Parents believe that giving too many vaccines to their children can cause problems. People actually don’t know what does vaccines are made of. â€Å"Vaccines contain live viruses, killed viruses, purified viral proteins, inactivated bacterial toxins, or bacterial polysaccharides.† (Offit). These viruses help the immune system make stronger and help fight diseases. Parents should vaccinate their children eve ry year, which will allow them to be healthy. Many people believe that vaccines are not safe to take because they can lead to problems but it’s a false statement. Measles vaccine was licensed in 1962 since then the case for measles has decreased. â€Å"If you look at the history of any vaccine-preventable disease, you will virtually always see that the number of cases of disease starts to drop when a vaccine is licensed.† (Vaccines Are Effective).
