For instance women lose a lot of blood every month during our periods, how does our body replace the blood we lost?

I work in a blood testing lab in England and i must say, thats not a simple question to answer! Red blood cells and most white cells are made in the bone marrow, the femur bone is the main source. Platelets used for clotting are made from broken down parts of red cells and other cells. Most blood is water and that is extracted from the intestine and stomach during digestion. Water you drink can be in your blood within minutes. Ather nutrients are also extracted during digestion. There are many hormones in blood too made in various glands including thyroid, pituitary, adrenal, pancreas, liver, testes, ovries etc. Providing your diet is ok your bone marrow can replace a pint of blood within about 24hours. Hope that helps!

The cells in blood are produced by the bone marrow, the proteins mostly by the liver, the hormones by the glands, and the watery stuff is maintained by several cooperating organs.
New blood is continuously being produced... red blood cells only last a few months before being too degraded to be of use and replaced by new cells.
The stuff coming off in menstruation is not just blood, but the endometrial lining of the uterus, which also regrows monthly (or whatever) to prepare for the implantation of an embryo.

RBC - thru haematopoiesis. this is occurring at all times in ur body WBC, platelets - in bone marrow but from different cells Plasma - water from inside cells move out to replace the lost plasma Water and iron are mainly from ur diet. but ur body will have a store of both at all times But u have to rmb tt nose bleed and all tt don't cause a big blood loss as u think... the body won't exactly feel the loss.

blood cells are formed in bone marrow in the long bones of the body femur for example

The body constantly "loses" and replaces blood.
It's constantly being made in the bone marrow. Beyond that, you'd need a good physiology course.

What a woman sheds every month is not exactly your regular blood. It's the lining of the uterus that will not be needed to cradle and nourish a baby... As for our normal blood, we don't usually go around shedding it... Google it. That will probably be a more efficient way to find this out, since most of us have sadly forgotten our biology lessons.

I think we replace it by, well obviousely, our heart pumps more blood, so we eat the right foods to get our heart to pump out more blood.
