Transport is the function |
|
|
What is the circulatory system composed of |
The heart Blood Arteries Veins Capillaries |
|
|
The heart |
Which pumps the blood around the body |
|
|
Blood |
Which carries the blood cells and key molecules around your body |
|
|
Arteries |
Carry blood from your heart |
|
|
Veins |
Carry blood back to the heart |
|
|
Capillaries |
Join arteries and veins through tissues and organs |
|
|
The Heart Diagram |
|
|
|
The Heart Full |
Is a pump that pushes blood around the body, organ made from muscle and nerve tissue. Contract and relax |
|
|
Pace maker |
Small bunch of cells in the wall of the top right chamber Generate electrical impulses which travel along its nervous tissues and cause contraction and controls your heart beat |
|
|
Blood Vessel Diagrams |
|
|
|
Blood Flow |
B returns from lungs and collected in left atrium (high in o2 and low in co2) Blood is pumped into the left ventricle, and pumped around the body Blood is taken to the right atrium by the vena cava (low o2 and high co2) Enters right ventricles and pumped to lungs |
|
|
Arteries diagram |
|
|
|
Arteries |
Cope with blood under high pressure as it is pumped from the ventricles They have thick walls made from elastic and muscle tissues and allows them to stretch. Pulmonary artery - only artery to carry deoxygenated blood |
|
|
Veins Diagram |
|
|
|
Veins |
Carry blood back to the heart at low pressure, wider than arteries and one way valves to keep blood flow in the correct direction |
|
|
Capillaries |
Tiny blood vessel that spread out like roots, very thin so lots of oxygen can diffuse from the blood into the cell |
|
|
Blood plasma |
The straw coloured liquid that carries our blood cells and dissolved molecules. |
|
|
Aorta |
Main artery coming from the left side of the heart, taking blood to tissues and organs |
|
|
Pulmonary Artery |
Main artery coming from the right side of the heart, taking blood to the lungs Deoxygenated blood |
|
|
Pulmonary Vein |
Main vein returning blood to the left side of the heart from the lungs |
|
|
Vena Cava |
Returning blood to the right side of the heart from the tissues and organs |
