Main Functions Of The Circulatory System
supply of blood to the lungs
Pulmonary Circulation
supply fo blood to the heart
Cardiac Circulation
supply of blood to all other tissues of the body
Systemic Circulation
3 Fundamental Features Of The Circulatory System
1) Heart
2) Blood Vessels
3) Blood
3 Parts Of Blood
1) Red Blood Cells
2) White Blood Cells
3) Platlets
3 Parts of Blood Vessels
1) Arteries
2) Capillaries
3) Veins
COMPONENTS
- biconcave disk (concave on both sides)
- carry oxygen and carbon dioxide for transportation
- erythroytes
Red Blood Cells
COMPONENTS
- particles in cytoplasm
- large, scavengers
- make up the immune system (protects)
- leukocytes
White Blood Cells
COMPONENT
- helps clot blood for repairment
- made of bone marrow
Platelets
carry oxygenated blood from the heart
Arteries
carry deoxygenated blood to the heart
Viens
walls are a thick layer of muscle that can withstand pressure
Artery
walls are a thin layer of muscle, only a one way valve
Vien
COMPONENT
- thin, 1 cell can fit
- internal respiration
- the exchange of O2 and CO2
- connects arterioles and venules
Capillaries
