blood carries oxygen, so it carries oxygen to your tissues, eg, all your muscles, so you can walk etc, (be alive) I THINK!

Why do Mammals with a high rate of respiration need to have a high heart rate?
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.
The function of valves in the cardiovascular system is to?
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.
What carries blood away from the heart toward the tissues?
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.
Why is it important for your heart to keep oxygen-rich blood separate from oxygen poor blood?
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.
Why there is slow of blood flow in a leg vein when there is a lack of movement?
I think because you don;t need as much blood when you're not using your muscles
Why do Mammals with a high rate of respiration need to have a high heart rate?
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.
How does blood flow through the brain to the heart?
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
Why do mammals with high respiration need to have a high heart rate?
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.
How much blood you donate?
Only 10% because you need blood to be alive and to breath correctly and you need blood to flow through you veins and arteries
I always have cold hands how do i get the blood to flow through them?
You need to warm them gradually or keep them warm all the time
What blocks blood flow to the kidneys?
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.
How do tissues get the oxygen they need for energy production?
The tissues get oxygen from oxygenated blood supply for energy production.
Why does the heart need valves?
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.
How is Peripheral Vascular Disease related to smoking?
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.
Why does the human heart need valves?

Would blood travelling from the brain need to pass through the heart to get to the foot or does it flow straight there?
Blood travelling 'from' any organ is in the venous system and will pass through the heart to be oxygenated, then into the arterial system on the way 'to' any organ.
