It depends on how big your body is. The larger you are the more blood vessels you have to supply the tissue. It is estimated that an extra 200 miles of blood vessels develop for each extra pound of fat.
The overweight person have got the same amount of blood. That is five liters in his body. Overweight person has got extra fat in his body, some times extra muscles.
If the blood vessels in the kidneys are damaged, they may stop removing wastes and extra fluid from the body. The extra fluid in the blood vessels may then raise blood pressure even more. It's a dangerous cycle.
It is a body fluid after all, so it can carry infection. But if it's from a healthy woman there's no special danger to period blood.
there is no danger. White blood cells keep you healthy
Extra blood is stored in the spleen and released when there is a shortage to help maintain adequate blood volume and pressure in the body. The spleen acts as a reservoir for red blood cells and can contract to release them into circulation when needed.
yes it is because your pancreas produces insulin. insulin is a hormone that helps your blood sugar.
The blood system makes extra blood to put in the womb but you may still feel light headed when you are on your period even though it does not take blood out of your vains.
When you are sick, extra white blood cells are created by the immune system to help fight off the infection or illness. White blood cells are an important part of the body's defense against pathogens and foreign invaders.
The spongy part of your bones (the bottom and top tips) create red blood cells. We do not "store" extra blood. Often our blood pressure would drop, (low blood volume) and to compensate your blood vessels will constrict (become smaller) so that it will seem like there is more blood in your system. Think of a four lane road compared to a one lane road(constricted)
The veins function as a blood reservoir and contain over 60 percent of the body's blood. This allows them to store extra blood that can be quickly mobilized when needed, such as during physical activity or in response to stress.
