Questions and Answers

Match the following heart valves with their locations:

Tricuspid valve = Between the right atrium and right ventricle Bicuspid (Mitral) valve = Between the left atrium and left ventricle Pulmonic valve = Within the opening of the pulmonary artery Aortic valve = Within the opening of the aorta

What is the function of the heart valves?

To prevent backflow of blood.

Which type of blood vessel carries oxygen-rich blood away from the heart?

  • Veins
  • Arteries (correct)
  • Capillaries
  • None of the above
  • Veins have thicker walls than arteries.

    Study Notes

    Tissue Layers of an Artery

    • Composed of tunica intima, basement membrane, tunica media, and tunica externa.

    Cross-Section of the Heart

    • Features major chambers: left atrium, right atrium, left ventricle, right ventricle.
    • Valves include tricuspid, mitral, pulmonic, and aortic valves.
    • Blood vessels: superior vena cava, inferior vena cava, pulmonary artery, and aorta.
    • Septum separates the left and right sides of the heart.

    Function of Heart Valves

    • Valves prevent backflow of blood, crucial for efficient circulation.
    • Atrioventricular (AV) valves: tricuspid (right side) and mitral (left side) connect atria to ventricles.
    • Semilunar (SL) valves: pulmonic (between right ventricle and pulmonary artery) and aortic (between left ventricle and aorta).
    • AV valves open during atrial contraction; SL valves open during ventricular contraction.

    Types of Blood Vessels

    • Closed circulatory system composed of arteries, veins, and capillaries.

    Arteries

    • Thick-walled to withstand high blood pressure.
    • Primarily transport oxygen-rich blood away from the heart.
    • Branch into smaller vessels known as arterioles.

    Veins

    • Thinner walls that can collapse easily.
    • Transport oxygen-poor blood back to the heart.
    • Largest vein is the vena cava, which splits into superior and inferior vena cava.

    Overview of the Circulatory System

    • Known as the cardiovascular system, it transports nutrients, gases, and hormones.
    • Composed of the heart, blood, and a network of blood vessels.

    Structure of the Heart

    • Four-chambered organ located centrally in the chest, size of a clenched fist.
    • Comprised of two atria (receiving chambers) and two ventricles (pumping chambers).
    • Right atrium receives oxygen-poor blood, while left atrium receives oxygen-rich blood.

    Blood Flow and Vessels

    • Vena cava delivers oxygen-poor blood to the right atrium.
    • Pulmonary artery carries blood from the right ventricle to the lungs.
    • Pulmonary veins bring oxygen-rich blood from the lungs to the left atrium.
    • Aorta distributes oxygen-rich blood from the left ventricle to the body; branches called coronary arteries supply the heart itself.
