    Explanation
    The correct answer is pericardium. The pericardium is a sacklike structure that surrounds the heart. It is made up of two layers, the outer fibrous pericardium and the inner serous pericardium. The pericardium helps protect the heart from external trauma and infection, and also provides lubrication for the heart to beat smoothly within the chest cavity.

    Rate this question:

  • 3. 

    Which chamber does deoxygenated blood first enter into after it has completed it voyage through the body?

    • Right ventricle

    • Right atrium

    • Left atrium

    • Left ventricle

    Correct Answer
    A. Right atrium
    Explanation
    After completing its journey through the body, deoxygenated blood first enters the right atrium. This is because the right atrium receives blood from the body through the superior and inferior vena cava. From the right atrium, the blood then flows into the right ventricle before being pumped to the lungs for oxygenation.

    Rate this question:

  • 4. 

    Blood flow entering the right atrtium, flows freely past a one-way valve called the

    • Aortic valve

    • Pulmonary valve

    • Mitral valve

    • Tricuspid valve

    Correct Answer
    A. Tricuspid valve
    Explanation
    The tricuspid valve is located between the right atrium and the right ventricle of the heart. It is responsible for ensuring that blood flows in only one direction, from the atrium to the ventricle. When the atrium contracts, the tricuspid valve opens, allowing blood to flow into the ventricle. Once the ventricle is filled, the valve closes to prevent blood from flowing back into the atrium. This allows for efficient blood flow through the heart and prevents any backward flow or regurgitation.

    Rate this question:

  • 5. 

    Blood is pumped from the right ventricle to the

    • Pulmonary artery

    • Pulmonary vein

    • Aorta

    • Right atrium

    Correct Answer
    A. Pulmonary artery
    Explanation
    The correct answer is pulmonary artery. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, where it picks up oxygen and gets rid of carbon dioxide. This oxygenated blood is then returned to the heart through the pulmonary veins. The aorta is the largest artery in the body and carries oxygenated blood from the left ventricle to the rest of the body. The right atrium receives deoxygenated blood from the body and pumps it into the right ventricle.

    Rate this question:

  • 6. 

    Which valve keeps blood from entering back into the right ventricle

    • Pulmonary

    • Mitral

    • Tricuspid

    • Aortic

    Correct Answer
    A. Pulmonary
    Explanation
    The pulmonary valve is responsible for keeping blood from flowing back into the right ventricle. This valve is located between the right ventricle and the pulmonary artery, and it opens to allow blood to flow into the pulmonary artery and lungs for oxygenation. Once oxygenated, the blood returns to the heart and enters the left atrium, passing through the mitral valve into the left ventricle. Therefore, the pulmonary valve plays a crucial role in ensuring that oxygenated blood flows in the correct direction, preventing any backflow into the right ventricle.

    Rate this question:

  • 7. 

    As in the right side of the heart there is a valve to prevent blood from slipping backward through the pulmonary vein.  It is called the

    • Pulmonary valve

    • Mitral valve

    • Tricuspid valve

    • Aortic valve

    Correct Answer
    A. Pulmonary valve
    Explanation
    The pulmonary valve is located on the right side of the heart and prevents blood from flowing backward through the pulmonary artery. It ensures that blood flows from the right ventricle to the lungs for oxygenation and prevents any backflow into the heart. The mitral valve is located on the left side of the heart and regulates blood flow between the left atrium and left ventricle. The tricuspid valve is also located on the right side of the heart and controls blood flow between the right atrium and right ventricle. The aortic valve is located on the left side of the heart and regulates blood flow from the left ventricle to the aorta.

    Rate this question:

  • 8. 

    From the left atrium blood passes another one way valve called the

    • Pulmonary valve

    • Mitral valve

    • Tricuspid valve

    • Aortic valve

    Correct Answer
    A. Mitral valve
    Explanation
    The mitral valve is the correct answer because it is the valve that separates the left atrium from the left ventricle in the heart. It allows blood to flow from the left atrium into the left ventricle during the relaxation phase of the cardiac cycle, and prevents backflow of blood into the atrium during the contraction phase. The other options, such as the pulmonary valve, tricuspid valve, and aortic valve, are all located in different parts of the heart and serve different functions.

    Rate this question:

  • 9. 

    The contraction of the left ventricle first forces the freshly oxygenated blood into

    • The carotid arteries

    • The abdominal aorta

    • The left atrium

    • The aortic arch

    Correct Answer
    A. The aortic arch
    Explanation
    When the left ventricle of the heart contracts, it pumps blood out of the heart and into the aorta, which is the largest artery in the body. The aorta then branches off into different arteries, including the carotid arteries and the abdominal aorta. The carotid arteries supply oxygenated blood to the head and neck, while the abdominal aorta supplies blood to the abdominal organs. The left atrium is not directly involved in receiving blood from the left ventricle, and therefore, the correct answer is the aortic arch.

    Rate this question:

  • 10. 

    The first 2 braches of the aorta are the

    • Innominate artery

    • Brachiocephalic artery

    • Subclavian artery

    • Coronary artery

    Correct Answer
    A. Coronary artery
    Explanation
    The correct answer is coronary artery. The question asks about the first two branches of the aorta, and the correct answer is the coronary artery. The coronary artery is responsible for supplying blood to the heart muscle itself. The other options listed, such as the innominate artery, brachiocephalic artery, and subclavian artery, are not the first two branches of the aorta.

    Rate this question:

  • 11. 

    The only artery that transports deoxygenated blood

    • Pulmonary vein

    • Pulmonary artery

    • Coronary artery

    • Coronary vein

    Correct Answer
    A. Pulmonary artery
    Explanation
    The pulmonary artery is the correct answer because it is the only artery in the given options that transports deoxygenated blood. The pulmonary artery carries blood from the heart to the lungs, where it picks up oxygen and becomes oxygenated. This oxygenated blood is then returned to the heart through the pulmonary veins. The other options, such as the coronary artery and coronary vein, are involved in the circulation of blood within the heart itself and do not transport deoxygenated blood.

    Rate this question:

  • 12. 

    The only vein that transports oxygenated blood back to the heart

    • Coronary vein

    • Pulmonary vein

    • Brachiocephalic vein

    Correct Answer
    A. Pulmonary vein
    Explanation
    The pulmonary vein is the correct answer because it is the only vein that transports oxygenated blood back to the heart. The pulmonary vein carries oxygen-rich blood from the lungs to the left atrium of the heart, where it is then pumped out to the rest of the body. The coronary vein carries deoxygenated blood from the heart muscle itself, while the brachiocephalic vein carries deoxygenated blood from the head and arms. Therefore, the pulmonary vein is the only vein involved in the transport of oxygenated blood.
