Normally, platelets look round and smooth, but when they begin to work to plug up they become spiky and ragged around the edges.  When an injury occurs to a blood vessel wall, the platelets respond by attaching themselves over the cut to form a temporary plug within minutes slowing the loss of blood.
 
 
In addition to carrying blood cells throughout your body, plasma also carries hormones, nutrients and chemicals, such as iron.    Plasma has the important function of maintaining the pH of the blood at approximately 7.4.

lungs head & arms liver digestive system kidneys  legs  pulmonary artery aorta pulmonary vein main vein Left  Right How does this system work? Circulatory System Vena cava
Our circulatory system is a double circulatory system.  This means it has two parts parts.  the  right  side of the system  deals with  deoxygenated  blood. the  left  side of the system  deals with  oxygenated  blood. Lungs Body cells
Parts of The Heart ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
This is a  vein . It brings blood from the body, except the lungs. Coronary arteries, the hearts own blood supply 2 atria 2 ventricles
Left Ventricle Left Atrium valve Artery to Lungs valve
Types of Blood Vessels ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
The ARTERY thick muscle and elastic fibres Arteries carry blood away from the heart. the elastic fibres allow the artery to  stretch  under pressure the thick muscle can contract to  push  the blood along.
thin muscle and elastic fibres veins have valves which act to stop the blood from going in the wrong direction. body muscles surround the veins so that when they contract to move the body, they also squeeze the veins and push the blood along the vessel. Veins carry blood towards from the heart.
Capillaries link Arteries with Veins the wall of a capillary is only one cell thick they exchange materials between the blood and other body cells. The exchange of materials between the blood and the body can only occur through capillaries.
artery vein capillaries body cell A collection of capillaries is known as a  capillary bed .
