Short term responses
One short term response when playing basketball is when your face starts to go red, this happens because the body gets too hot and it tries to cool the body down by bringing blood to the surface of the skin to let some heat out and the skin also produces sweat to let out heat, therefore the skin surface goes red. Another short term response to physical activity is that your breathing rate and heart rate increases, the reason this occurs is because the muscles are being made to work harder and as a result of that the muscles need more oxygen so therefore you need to breathe in more oxygen and breathe out more carbon dioxide to keep the muscles going. Another short

The increase in oxidative capacity is achieved by an increase in the number of mitochondria (An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.) within the muscle cells, an increase in the supply of ATP and an increase in the quantity of enzymes involved in respiration. Another long term change that occurs due to training is that the heart gets larger; the result in the change is due to increased stress on the heart. The extra work of pumping blood against the increased pressure causes the heart wall to thicken over time, the same way a body muscle increases in mass in response to weightlifting. A long term change in the cardiovascular system as a result of training is that the resting heart rate gets lower, the cardiovascular response happens because a person that has been training for a long time has a lower heart rate because through exercise, they have a stronger heart; meaning that an athlete 's heart can pump more blood and more oxygen out with one pump than a non-athlete 's heart could. Another long term response in the cardiovascular system is that the blood supply increases, this change is due to your body needing more oxygen because you are exercising, your muscles and all your body organs are needing more energy and oxygen, this is because your body is working more than usual. Your body needs to do many things such as sweat, which helps you cool down, and to
You work in a small family practice in rural Virginia, (much better than Texas!). A man in his early 50s comes in with a complaint of intermittent fever (102-103 F) and headache for the past two weeks. The physician examines him and takes a history. The only clinical finding is a wound about the size of a quarter on his right thumb. Axillary lymph nodes are swollen and tender. The man says he cut himself while skinning a rabbit three days ago. On the basis of these observations the physician prescribes streptomycin and asks the man to call if his symptoms don’t improve in three days.
As Jim’s muscles are at maximum demand, his mitochondria are unable to produce the needed ATP through aerobic respiration because oxygen is unable to diffuse fast enough into his muscle fibers. At this time anaerobic
Homeostatic is all about balance so when you begin to exercise, you need more oxygen. The harder you breathe the more energy it takes to replace it. Your body temperature while exercising also increases; typically it creates too much heat so your body has to figure out a way to release the heat so it doesn't become dangerous. This is done by sweating
Exercise affects these systems, causing the heart to pump blood faster around the body, which in turn allows you to exercise for longer. http://www.bbc.co.uk/schools/ gcsebitesize/pe/appliedanatomy/0_ anatomy_circulatorysys_rev1.shtml The four main parts of the cardiovascular system is the heart, the veins, capillaries and the arteries.
Define equilibrium potential: Equilibrium channels can be calculated using the Nernst Equation and the Goldman-Hodgkin-Katz equation. Equilibrium potentials are membrane potentials when an ion does not diffuse through the membrane. It is also associated with potassium leaving the cell through leak channels.
Anatomy and Physiology is the study of the human body. Anatomy is the study of the internal and external structure of body parts. Physiology is the study of the function of those body parts.
I have written to you today to express my sincere interest in joining the Veteran Affairs San Diego accredited Postgraduate Year 1 (PGY1) residency program. I recently had the distinct pleasure of getting to learn more about your program at California Society of Health- System Pharmacists (CSHP). I came away impressed with the opportunities offered at VA San Diego pharmacy residency program.

Investigating the Effect of Exercise on Pulse Rate Aim: To see what happens to the pulse rate during exercise. Prediction: I predict that the pulse rate will increase in order to take more oxygen for respiration. The heartbeat will increase and become stronger to transport oxygen and carbon dioxide to and from the muscle cells. The breathing rate will increase in order to get rid of the extra waste such as Carbon dioxide. Respiration is the release of energy.
As the intensity of exercise increased, so did the rates of the heart and breathing. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. This proved the stated hypothesis. First, the hearts average resting rate was recorded to be 76 bpm. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. During the low intensity exercise (Slow 20) the heart rate increases to 107 bpm, which further increases to 130bpm at a higher intensity level (Fast 20). The heart therefore needs to beat faster to increase the speed at which oxygen is carried to the cells and the rate at which carbon dioxide is taken away by the blood.

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise.
Blood comes from the heart. In order to reach the high demand for blood with oxygen, the heart pumps faster and faster in order to let enough blood come out into the body. So the basketball player’s heart rate increases. This is because the working muscle needs more oxygen to contract. The more oxygenated blood the body can supply to working muscles, the greater intensity the basketball player can play the game However, the heart rate cannot keep at a fast rate for all the time.
My junior year I had the opportunity to take an anatomy class.This, partnered with my psychology class, was one of the most fascinating classes I have taken in my high school careers. Learning about the human body fascinated me as it was something that was so applicable, something that related to how I live my life everyday.
The muscles demand more energy and oxygen due to the increased workload that comes from exercise. This causes the heart rate and respiratory rate to increase in order to provide the required additional fuel to the muscles. In addition, the entire circulatory system works more efficiently due to vascular dilation and cholesterol reduction. By improving the condition of your cardiovascular fitness you are also helping yourself live longer, decrease the risk of heart disease, lower blood pressure, strengthen your cardiovascular system, and the list goes on. These reasons alone could save you from having heart disease.
