The hormone ADH regulates the water content of the blood. The higher the water content higher the pressure and volume of the blood. 11. The blood will flow into the portal system through the first set of capillaries, with a portal system there are two sets, through an artery then into the next capillary bed. After entering this second set of capillaries it drains by the way of a venule. It then drains into the venous circulation. 12. The body would sense the blood loss and it would trigger the heart to increase the heart rate and the blood vessels would constrict, or become more narrow, in the areas where blood flow is less important. The majority of the blood would still be circulating to the most important organs and to the brain. The kidneys are stimulated to release more renin. The adrenal gland will release to help increase blood volume. Also, the body will draw more fluid into the capillaries from the interstitial spaces and back into the plasma. 13. It would be easier to breathe when the barometric pressure is higher. When the pressure is low there is fewer oxygen molecules and more water molecules so with each breath there will be less oxygen taken in making it harder to …show more content…
By breathing faster all he is doing is exchanging CO2 more quickly. In return, I think this would keep the available oxygen from being released into his tissue and most importantly his brain. This would be because the presence of CO2 attracts the need for oxygen. 15.Harry's blood would become more alkaline and that causes the blood vessels to dilate in order for your body to function properly it does need a certain amount of carbon dioxide. Without this, the blood has to move faster this causes the vessels to dilate and that in return will cause the blood pressure to
