Physiology Assignment Physiology Assignment 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

caused by the tightness of the muscles in the airways‚ which therefore causes the individual with this condition to breathe out reduced amount of air which then leads to difficulty in inhaling and exhaling. According to the World Health Organization (2010)‚ this condition is due to inflammation of the air passages in the lungs and affects the sensitivity of the nerve endings in the airways so they become easily irritated. In an attack‚ the lining of the passages swells causing the airways to narrow

Physiology Assignment After searching for a couple of days and still being unsure of what I was going to write about I turned and was watching my fish in my fish tank and realized that was what I would do it on. Then I realized that I spend many hour throughout the week watching my fish swim around‚ it is almost therapeutic. I found that the anatomy and physiology of a fish is very unique so that they can exist in the different underwater environments. In this paper we will cover their circulatory
