A powerpoint presentation about "Heart" in Science 9

1. THE VOIDS
HEART

2. Heart <3
•The heart is a hollow muscular organ
that pumps blood throughout the blood
vessels to various parts of the body

3. PARTS OF
THE HEART

4. 1. Atrium-upper thin walled chambers of the heart.
2. Right Atrium-collects blue venous blood from the
heart.
3. Left Atrium-receives red oxygenated blood from the
lungs.
4. Ventricles-lower thick walled chamber; pumping
chamber of the heart.
5. Right Ventricle-pumps blue venous blood out of the
heart and to the lungs for oxygenation.
6. Left Ventricle-pumps oxygenated blood out of the
heart to all parts of the body.
7. Tricuspid Valve-between the right atrium and the
right ventricle.
8. Bicuspid Valve-aortic valve and left ventricle.
9. Pulmonary Semilunar Valve-between the right

5. ventricle and the pulmonary artery.
10. Aortic Semilunar Valve-between the left ventricle
and the aorta.
11. Septum-divides the heart into its right and left part.
12. Superior Vena Cava-located at the upper part of
the heart and brings blood from the head and the
arms.
13. Interior Vena Cava-located at the lower part of the
heart and bring blood from the lower parts of the
body.
14. Pulmonary Artery-carries deoxygenated blood from
the right ventricle of the heart to the lungs.
15. Pulmonary Vein-an exceptional vein.
16. Aorta-largest artery in the human heart.
