Question

level one questions:

1. how many chambers are inside the human heart?
2. what are the top chambers called?
3. what are the bottom chambers called?
4. name the two large veins that bring blood into the right atrium.
5. what is the job of the pulmonary artery?
6. what is the job of the pulmonary vein?
7. where is the tricuspid valve?
8. where is the bicuspid valve?
9. is the blood leaving the right ventricle oxygenated or deoxygenated?
10. is the blood leaving the left ventricle oxygenated or deoxygenated?
11. what is the job of the aorta?

Explanation:

1. The human heart has four distinct chambers.
2. The upper chambers of the heart are called atria (singular: atrium).
3. The lower chambers of the heart are called ventricles.
4. The two large veins that deliver deoxygenated blood to the right atrium are the superior and inferior vena cava.
5. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
6. The pulmonary vein carries oxygenated blood from the lungs back to the left atrium of the heart.
7. The tricuspid valve is located between the right atrium and the right ventricle.
8. The bicuspid (mitral) valve is located between the left atrium and the left ventricle.
9. Blood leaving the right ventricle is deoxygenated, as it is en route to the lungs.
10. Blood leaving the left ventricle is fully oxygenated, ready to be pumped to the entire body.
11. The aorta is the body's main artery; it carries oxygenated blood from the left ventricle to all tissues and organs of the body.

Answer:

1. 4
2. Atria (Right Atrium and Left Atrium)
3. Ventricles (Right Ventricle and Left Ventricle)
4. Superior Vena Cava and Inferior Vena Cava
5. To carry deoxygenated blood from the right ventricle to the lungs to pick up oxygen.
6. To carry oxygenated blood from the lungs back to the left atrium of the heart.
7. Between the right atrium and the right ventricle of the heart.
8. Between the left atrium and the left ventricle of the heart.
9. Deoxygenated
10. Oxygenated
11. To carry oxygenated blood from the left ventricle to all parts of the body.
