10. Structure of the heart BLOOD VESSELS
Septum

11. Functions of the chambers
The right atrium takes deoxygenated blood from the vena cava and stores it before sending it through the tricuspid valve.
The right ventricle receives de-oxygenated blood through the tricuspid valve before pumping it up the pulmonary artery to the lungs.

12. Functions of the chambers
The left atrium
The left ventricle

13. Functions of the valves
The tricuspid valve stops blood flowing back into the right atrium.
The bicuspid valve
The semi lunar valves stop blood flowing back into the left and right ………………

14. Functions of the blood vessels
The vena cava transports de-oxygenated blood from the body to the heart. Here is gives the oxygen to the working muscles.
The pulmonary artery

15. Functions of the blood vessels
The pulmonary vein transports oxygenated blood from the lungs to the heart.
The aorta

16. Blood Vessels
Arteries
Veins
Capillaries

17. Thermoregulation: Vasodilation of vessels
This is when you body temperature rises.
It is when the blood vessels expand, meaning the blood flows nearer to the surface of the skin.
It is a way of cooling you down.
It makes your skin become red after a heart raising activity.

18. Thermoregulation: Vasoconstriction of vessels
This is when your body temperature decreases, which makes your blood vessels constrict.
This means less blood flows near the surface of your skin so less heat is lost.
It happens when you are
It happens when you are cold.
