To have a high rate of respiration requires a high blood flow to distribute the oxygen to the tissues, this increases the heart rate it also increasing the blood flow to the tissues.
they need to open and close to allow blood to flow through the heartto prevent blood from flowing backwards when traveling through the heartThe heart has four chambers where blood is pumped. The four heart valves are the tricuspid, pulmonary, mitral, and aortic. The valves open and close to let the blood flow in only one direction.to pump blood throughout the body!To keep blood flowing they close between beats so it doesn't drain outThe purpose of the heart valves is to avoid back flow of blood.
It would be better to say what type of waste, if it is carbon dioxide you are talking about the red blood cells do some of that. There is a lot of waste products, specify which one and we can try and tell you.
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
I think because you don;t need as much blood when you're not using your muscles

trace blood flow through the kidney from the renal artery to the renal vein? blood flow through kidney from renal artery to the renal vein
Only 10% because you need blood to be alive and to breath correctly and you need blood to flow through you veins and arteries
The answer is quite simple. To have a high rate of respiration requires a high blood flow to distribute the oxygen to the tissues. Increasing heart rate is one means of increasing the blood flow to the tissues. The other means in increasing the amount of blood that is from the left ventricle with each contraction.
Oxygen is inhaled into the lungs, where it is transferred to the blood and carried by red blood cells to tissues. Carbon dioxide is produced by cells as a waste product and transported back to the lungs through the blood to be exhaled. This flow of oxygen and carbon dioxide ensures that cells receive the oxygen they need for energy production and get rid of carbon dioxide.
You need to warm them gradually or keep them warm all the time
The kidneys need a good blood supply. The main artery to the kidney is called the renal artery. Reduced blood flow through the renal artery can hurt kidney function. A complete blockage of blood flow to the kidney can often result in permanent kidney failure.
The tissues get oxygen from oxygenated blood supply for energy production.
The reason why we need we need valves in our heart is because the valves in our heart will open and close. When the valves in our heart open, they allow blood to go into places in our body where blood is needed. When the blood passes through, the valve closes. They regulate the blood flow.
PVD is caused by a slowage or stoppage of blood through the blood vessels in the arms and legs. Smoking causes vasoconstriction ( constriction or narrowing of the blood vessels). When the blood can't flow as fast through the veins (because they are narrowed), the tissues are waiting for the blood get to them because they need oxygen to produce energy. In the meantime they need energy to survive so they produce the energy without oxygen. The byproduct of that production is lactic acid, which builds up in the tissue causing the pain you experience with PVD.

Oxygen is transported to the respiring tissues through the bloodstream. It is first inhaled into the lungs, where it diffuses into the blood vessels in the alveoli. Hemoglobin in red blood cells binds to the oxygen, allowing it to be carried throughout the body and released to cells in need of oxygen for respiration.
