Cardiovascular system Part 2
Erythrocytes(red blood cells)
The main function is to carry oxygen
Anatomy of circulating erythrocytes:
Biconcave disks
Essentially bags of hemoglobin
Anucleate (no nucleus)
Contain very few organelles
Leukocytes (White Blood Cells)
Crucial in the body’s defense
against disease
These are complete cells, with a
nucleus and organelles
Able to move into and out of
blood vessels
Can respond to chemicals
released by damaged tissues
Platelets
Derived from ruptured
multinucleate cells
Needed for the clotting process
Blood usually clots within 3 to 6
minutes
The clot remains as endothelium
The clot is broken down after tissue
repair
