1. Heart Part 1

2. Three major parts of the circulatory system
Blood
The fluid that serves as the medium of transport
Blood vessels
A system of channels that conduct the blood through the body
Heart
A pump that keeps the blood circulating through the body

3. Flow of blood
Right Atrium [Tricuspid Valve] Right Ventricle[Pulmonary Semilunar Valve] Right and Left Pulmonary Arteries  Lungs Pulmonary Veins  Left Atrium [Bicuspid Valve] Left Ventricle[Aortic Semilunar Valve] Aorta  Arteries  Arterioles Capillaries  Venules  Veins  Superior / Inferior Vena Cava  Right Atrium

4. Major Blood Vessels Pulmonary Arteries Pulmonary Veins Aorta
Leave the right ventricle and branch to the left/right, carrying deoxygenated blood to the lungs
Pulmonary Veins
The vein through which oxygenated blood from the lungs returns to the left atrium
Aorta
Takes oxygenated blood from the heart to the body

5. Inferior Vena Cava
Returns blood to the heart from the legs, pelvis, and abdomen
Superior Vena Cava
Returns blood to the from the head and arms

7. The Heart

8. Right Side
Left Side
Show the heart as if you were looking at someone laying in front of you. Therefore the sides are opposite to you

9. Anatomy of the Heart The hear has 4 chambers Left Atrium Right Atrium
Left Ventricle
Right Ventricle
Ventricles are separated
by a septum

10. Atria Right Atrium Left Atrium
Receives deoxygenated blood from the body via the vena cava
Left Atrium
Receives oxygenated blood from the lungs via the pulmonary veins
Pumps blood to the left ventricle

11. Ventricles Right ventricle Left Ventricle
Receives deoxygenated blood from the right atrium
Pumps blood to the lungs via the pulmonary arteries
Left Ventricle
Receives oxygenated blood from the left atrium
Pumps blood into the aorta

12. Septum The septum separates the left and right ventricles
Prevents oxygenated and deoxygenated blood from mixing in the heart

13. Aorta Superior Vena Cava Left Pulmonary Artery Right Pulmonary Artery
Left Pulmonary Veins
Right Pulmonary Veins
Inferior Vena Cava

14. Heart Valves Atrioventricular valves Semilunar Valves
Open one way between the atria and ventricles
Prevent blood from flowing backwards into the atria
Semilunar Valves
Open one way between the ventricles and blood vessels that are coming out of the heart

16. Atrioventricular Valves (AV Valves)
Tricuspid Valve
Between the right atrium and the right ventricle
Bicuspid (mitral) Valve
Between the left atrium and the left ventricle

17. Semilunar Valves Pulmonary Semilunar Valve Aortic Semilunar Valve
Between the right ventricle and pulmonary artery
Aortic Semilunar Valve
Between the left ventricle and aorta

19. The Heart Pulmonary Circulation Systemic Circulation Right Side
Left Side
Receives deoxygenated blood from body tissue
Pumps blood to the lungs
Received oxygenated blood from lungs
Pumps blood to the body tissue
