The medulla oblongatta of the brain stem is the cardiac center that controls blood flow.
The ancestors of all the blood cells are called hematopoietic (blood forming) stem cells.
proerythroblasts
There is a hormone produced by the kidneys called erythropoietin that stimulates production of red blood cells. Certain cytokines such as colony stimulating factors and interleukins produced by the red bone marrow drive development of white blood cells. Both white and red come from the same hemopoietic stem cell. Changing pressure of the flow of liquids around stem cells can induce cells to become artery cells.
Vessicles are rather primitive and present all-throughout.

Stemflow is the flow of intercepted water down the trunk or stem of a plant.
The four valves in the heart are: * the two semi-lunar valves - one at the stem of the aorta, the other is found at the trunk of the pulmonary artery. * The tricuspid valve is on the right-hand side of the heart. * The bicuspid valve is on the left side of the heart.
Vessicles are rather primitive and present all-throughout.
The blood cell begin their lives in the bone marrow from a single type of cell called pluripotent hematopoietic stem cell.All the circulating blood cells are eventually derived from PHSC.

Personally, when I have a nose bleed, I stuff a small wad of cotton wool up into the offending nostril, and wait for the platelets in the blood to stem the flow.
Peripheral blood stem cells (PBSCs) are obtained from circulating blood rather than from bone marrow, but the amount of stem cells found in the peripheral blood is much smaller than the amount of stem cells found in the bone marrow.
