Circulatory System
By: Dante George
2
Is made up of:
Blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart.
3
It Carries:
Oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Parts of the Heart

7
The atria are separated from the ventricles by the atrioventricular valves:
8
The tricuspid valve separates the right atrium from the right ventricle.
9
The mitral valve separates the left atrium from the left ventricle.
10
11
The pulmonic valve is between the right ventricle and the pulmonary artery, which carries blood to the lungs.
12
The aortic valve is between the left ventricle and the aorta, which carries blood to the body.

What Are the Parts of the Circulatory System?
14
15
The pulmonary circulation is a short loop from the heart to the lungs and back again.
16
The systemic circulation carries blood from the heart to all the other parts of the body and back again.
17
In pulmonary circulation:
The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
