What is the function of Erythropoietin (EPO)?
It triggers the development of megakaryocytes into platelets.
It prompts the production of erythrocytes.
It stimulates the proliferation of progenitor cells.
It acts as a paracrine factor.
Which hormone triggers the development of megakaryocytes into platelets?
( produced by the liver and kidneys )

What happens during vascular spasm?
