Use the following diagram to review the flow of blood through a h ... - Free Printable

The image provided is a diagram of the human circulatory system, specifically focusing on the heart and its associated blood vessels. Below is the labeled explanation for each part of the diagram:

Diagram Labels and Explanations:

1. p.
- Label: Pulmonary Artery
- Explanation: This artery carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.

2. o.
- Label: Right Ventricle
- Explanation: The lower right chamber of the heart that pumps deoxygenated blood into the pulmonary artery.

3. n.
- Label: Right Atrium
- Explanation: The upper right chamber of the heart that receives deoxygenated blood from the body via the superior and inferior vena cava.

4. m.
- Label: Superior Vena Cava
- Explanation: A large vein that returns deoxygenated blood from the upper body to the right atrium of the heart.

5. l.
- Label: Inferior Vena Cava
- Explanation: A large vein that returns deoxygenated blood from the lower body to the right atrium of the heart.

6. k.
- Label: Aorta
- Explanation: The largest artery in the body, which carries oxygenated blood from the left ventricle to the rest of the body.

7. j.
- Label: Left Atrium
- Explanation: The upper left chamber of the heart that receives oxygenated blood from the lungs via the pulmonary veins.

8. h.
- Label: Left Ventricle
- Explanation: The lower left chamber of the heart that pumps oxygenated blood into the aorta to be distributed throughout the body.

9. i.
- Label: Systemic Circulation
- Explanation: The pathway of blood flow from the heart to the body tissues and back to the heart.

10. a.
- Label: Lungs
- Explanation: Organs responsible for gas exchange (oxygen and carbon dioxide) between the blood and the air.

11. b.
- Label: Pulmonary Veins
- Explanation: These veins carry oxygenated blood from the lungs to the left atrium of the heart.

12. c.
- Label: Tricuspid Valve
- Explanation: A valve located between the right atrium and the right ventricle, preventing backflow of blood during contraction.

13. d.
- Label: Bicuspid (Mitral) Valve
- Explanation: A valve located between the left atrium and the left ventricle, preventing backflow of blood during contraction.

14. e.
- Label: Semilunar Valves
- Explanation: Valves located at the base of the aorta and pulmonary artery, preventing backflow of blood when the heart relaxes.

15. f.
- Label: Chambers of the Heart
- Explanation: Refers to the four chambers of the heart: right atrium, right ventricle, left atrium, and left ventricle.

16. g.
- Label: Coronary Arteries
- Explanation: Blood vessels that supply oxygenated blood to the heart muscle itself.

Summary of the Circulatory System:

- Pulmonary Circuit: Deoxygenated blood leaves the heart via the pulmonary artery, travels to the lungs for oxygenation, and returns to the heart via the pulmonary veins.
- Systemic Circuit: Oxygenated blood leaves the heart via the aorta, travels to the body tissues, and returns to the heart via the vena cavae.
