Cardiovascular System
Characterize the 3-formed elements in the blood.
Erythrocytes (RBC) Leukocytes (WBC) Platelets
Most numerous
O2 transport (filled with
haemoglobin) Protect body from infections Clotting of blood
Platelet plug
No organelles
– don't need energy to function
- packed full of only haemoglobin
(efficient O2 transport)
Function outside the blood
stream by :
DIAPEDESIS : leave capillaries
to go where needed
Cell fragments (not true cells)
2 type:
granulocytes :
- neutrophils
- eosiniphils
- basophils
- lymphocytes
- monocytes
At a cut platelet rushes to the site
– shoots a net and other platelets
Originate – bone marrow Formed – bone marrow
