Trace the blood flow through the heart
Correct Answer
Superior and Inferior Vena Cava, Coronary sinus, right atrium, tricuspid valve, right ventricle, pulmonary semilunar valves, pulmonary trunk, pulmonary arteries, lungs, pulmonary veins, left atrium, bicuspid valves, left ventricle, aortic semilunar valves, aorta and bodyExplanation
The blood flow through the heart starts with the Superior and Inferior Vena Cava, which bring deoxygenated blood from the body to the right atrium. From there, the blood flows through the tricuspid valve into the right ventricle. When the right ventricle contracts, the blood is pumped through the pulmonary semilunar valves into the pulmonary trunk and then into the pulmonary arteries, which carry the blood to the lungs. In the lungs, oxygen is added to the blood and carbon dioxide is removed. The oxygenated blood then returns to the heart through the pulmonary veins, entering the left atrium. From there, the blood flows through the bicuspid valves into the left ventricle. When the left ventricle contracts, the blood is pumped through the aortic semilunar valves into the aorta, which carries the oxygenated blood to the rest of the body.Rate this question:

What king of blood enters the Superior and Inferior Vena Cava?
- A.
Oxygenated
- B.
Deoxygenated
Correct Answer
B. DeoxygenatedExplanation
The blood that enters the Superior and Inferior Vena Cava is deoxygenated. The Vena Cava is responsible for carrying blood from the body back to the heart. After the oxygen in the blood has been used by the body's tissues, the deoxygenated blood returns to the heart through the Vena Cava to be pumped to the lungs for oxygenation. Therefore, the correct answer is deoxygenated.Rate this question:

Systole if when the atrium is contracting
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given statement is incorrect. Systole refers to the contraction phase of the heart, but it specifically refers to the contraction of the ventricles, not the atrium. During systole, the ventricles contract and pump blood out of the heart, while the atria relax and fill with blood. Therefore, the correct answer is false.Rate this question:
