Outline the components of the circulatory system and the blood
The circulatory system is made up of the heart, blood vessels and the blood. It has two circuits the pulmonary and systemic. The pulmonary circuit carries blood to the lungs that needs to be oxygenated and brings it back to the heart again. In the systemic circuit it carries the oxygenated blood around the body and the deoxygenated blood returns to the heart. The Heart …show more content…
Pumps blood around the body four chambers – Two atria (collects the blood) – Two Ventricles(pumps blood out the heart)
The septum seperates the left and right side of the heart
The right side pumps deoxygenated blood(pumps blood to lungs to collect oxygen) and the left side pumps oxygenated blood (pumps blood around the body lungs included)
Blood Vessels
Theres three types of blood vessels they are known as the arteries,veins and the cappillaries.
Arteries
Have a thick wall
Have a small lumen
Carry blood AWAY from the heart
Don't have any valves
Veins
Have a thin wall
Have a large lumen
Carry blood TO the heart
Have valves
Capillaries lets the exchange of gas to take place it's one cell thick
The Blood
The blood is made up of 4 parts, the white blood cells, red blood cells, plasma and platelets.
White Blood Cells
They are also known as leucocytes, it's made in the bone marrow and it's function in the immune system is to fight infection and produce antibodies.
Red Blood Cells
Red blood cells are also produced in the bone marrow and they are known as erythrocytes. The function for red blood cells is to transport oxygen because it contains haemoglobin.
Plasma
Plasma is a yellow liquid colour and makes up about 55% of the blood volume and it transports materials such as carbon dioxide, food and heat.
