Study Notes
- Blood's formed elements include erythrocytes, leukocytes, and platelets.
- Erythrocytes' main function is transporting oxygen and carbon dioxide.
- Plasma is the liquid matrix of blood.
- Hemopoiesis occurs in red bone marrow of adults.
- Pluripotential stem cells give rise to all blood cell types.
- Neutrophils are granulocytes.
- Erythrocytes have an average life span of 120 days.
- Platelets originate from megakaryocytes.
