    • C.

      Pericardium

    • D.

      Endocardium

    Correct Answer
    C. Pericardium
    Explanation
    The heart is enclosed in a membranous sac called the pericardium. The pericardium is a double-layered sac that surrounds and protects the heart. It consists of two layers, the fibrous pericardium, which is the outer layer, and the serous pericardium, which is the inner layer. The pericardium helps to prevent the heart from overexpanding, provides lubrication for the heart to move within the chest, and acts as a barrier against infection and inflammation.

  • 9. 

    The relaxation phase of the blood pressure is called?

    • A.

      Systole

    • B.

      Dyastole

    • C.

      Pulse Pressure

    • D.

      Median Pressure

    Correct Answer
    B. Dyastole
    Explanation
    The relaxation phase of the blood pressure is called diastole. During diastole, the heart muscles relax, allowing the chambers of the heart to fill with blood. This is the phase when the blood pressure is at its lowest point. Systole, on the other hand, is the contraction phase of the heart when blood is pumped out of the heart. Pulse pressure refers to the difference between the systolic and diastolic blood pressure, while median pressure is not a term used to describe the phases of blood pressure.

    What venous system has the only veins in the bdoy that carry freshly oxygenated blood?

    • A.

      Hepatic

    • B.

      Systemic

    • C.

      Portal

    • D.

      Pulmonic

    Correct Answer
    D. Pulmonic
    Explanation
    The pulmonic venous system is the only venous system in the body that carries freshly oxygenated blood. This system carries blood from the lungs back to the heart, specifically from the pulmonary veins to the left atrium. The other options mentioned in the question, such as the hepatic, systemic, and portal venous systems, do not carry freshly oxygenated blood. The hepatic venous system carries blood from the liver to the inferior vena cava, the systemic venous system carries deoxygenated blood from the body back to the heart, and the portal venous system carries blood from the digestive organs to the liver.

    What is dome shaped and separated the thoraci and Abdominal cavaities?

    • A.

      Mediastinum

    • B.

      Intercostal Muscles

    • C.

      Diaphragm

    • D.

      Lungs

    Correct Answer
    C. Diaphragm
    Explanation
    The diaphragm is a dome-shaped muscle that separates the thoracic and abdominal cavities. It plays a crucial role in respiration by contracting and flattening when we inhale, allowing the lungs to expand and fill with air. When we exhale, the diaphragm relaxes and returns to its dome shape, pushing the air out of the lungs. Therefore, the diaphragm is responsible for the separation and movement of air between the thoracic and abdominal cavities.
