Pulmonary & Systemic Circulation
THE CIRCULATORY SYSTEM- TRANSPORT
The absorption and circulation of materials throughout an organism.
In general, the blood is a fluid tissue helping to maintain
for all cells in the body.
Transport of needed substances to body cells. (oxygen, amino acids, glucose, fatty acids, glycerol, salts ,etc.)

Heart pumps blood troughout the body.
FUNCTION OF THE CIRCULATORY SYSTEM
to body cells.
and others waste products away from cells.
movement of materials into and out of cells occurs by
(from an area of high concentration to low concentration- no energy required.
movement also occurs by
(from an area of low concentration to high- this requires energy.
Consist of the right and left atria, and the right and the left ventricles.
The right side of the heart pumps blood to the lungs, while the left side pumps blood to the other parts of the body.
PATH OF BLOOD FLOW
Whole body except lungs
THE PULMONARY CIRCULATION
Transport blood from the heart to the lungs and back to the heart. [heart lungs heart]
Ensures that blood poor in oxygen receives fresh oxygen supplies in the lungs.
THE SYSTEMIC CIRCULATION
Transport blood from the heart to all parts of the body and back to the heart.
[heart all parts of the body (except the lungs)
Ensures body cells and body tissues receive oxygenated blood and metabolic waste products like carbon dioxide to be expelled.
Transport of wastes
from cells. (urea water , carbon dioxide in the form of the bicarbonate ion)
Helps to maintain a
constant body temperature
Aids the body in
