The organs do this by varying the relative resistance of their own arterioles.
how does ATPP regulate its own
they need the heart to pump them
Almost none. It does control its own flow, and it will speed the heart in anticipation of need, but that does not effect the actual flow of blood.
Pulmonary circulation (between the heart and lungs) Systematic circulation (between the heart and the rest of the body) Coronary circulation (the heart's own blood supply/supply to cardiac tissue)
Yup, blood is made in the bone marrow and then when its old its broken down in the liver. You only get a blood transfusion when you have lost so much blood that your vital organs can no longer function or when your getting surgery to replace the blood lost when they are cutting you open.
it starts with the hear and enters the valve through the atrium
The Coronary arteries carry blood to the heart so the heart has its own supply of oxygen and nutrients to perform its function.
In a healthy person, white blood cells only attack invading germs, and would not attack the person's own internal organs. However, there are autoimmune diseases, which cause the immune system to become confused and to attack the wrong targets.

child are playful and adult care about serious things for their life. Children think in the short term and mostly about their own needs. Adults think in the long term and how they can help others: be productive.
Snakes are cold blooded, or exothermic - this means that that cannot regulate their own internal body temperature, and instead their blood temperature changes with the temperature of their surrounding environment.
After Arthroscopy, your internal organs shut down but your blood is still pumped round your body so your body effectively drowns in its own blood.
