How does the blood maintain homeostasis?

Answer 1

I think pumping the heart I actually forgot so yeah.......

Answer 2

Blood cells are produced in the bone marrow, a jellylike substance inside the bones that is mainly made up of, fat, blood, and stem cells that are able to turn into the sorts of blood cells required at any given time. In children, the marrow of most of the bones produces blood. However in adults the marrow of only certain bones such as the spine, ribs, pelvis, and some others still make blood. Bone marrow that produces blood cells is called red marrow, and bone marrow that no longer produces blood cells is called yellow marrow.

All blood cells come from "stem cells" and they are able to turn into any kind of blood cell. These are known as pluripotential hematopoietic stem cells.

As blood cells develop from stem cells in the bone marrow, they seep into the blood as it passes through the bones into the bloodstream. The differing blood cells have differing life spans, red blood cells last about 120 days in the bloodstream while platelets last about 10 days The different sorts of white blood cells last anywhere from days to years.

If oxygen levels in the body become low which will happen if there is a shortage of red blood cells, a hormone is produced by the kidneys called erythropoietin. This stimulates the stem cells in the marrow to produce more red blood cells.

Answer 3

Erythrocytes have semi-permiable membranes and their volume is controlled by the ionic concentration in their environment

Answer 4
