      Tunica externa (loose fibrous connective tissue)

    Correct Answer
    D. Elastin
    Explanation
    Elastin is the correct answer because it is a protein found in the walls of blood vessels, particularly in the tunica media layer. Elastin provides elasticity to the blood vessels, allowing them to stretch and recoil as blood flows through them. This elasticity helps maintain proper blood pressure and prevents damage to the vessels.

    Correct Answer
    F. Tunica media (smooth muscle)
    Explanation
    The correct answer is tunica media (smooth muscle). In the walls of blood vessels, the tunica media is the middle layer that contains smooth muscle cells. These smooth muscle cells are responsible for regulating the diameter of the blood vessel, which in turn controls blood flow and blood pressure. The tunica media is thicker in arteries compared to veins, as arteries need to withstand higher pressure.

    • D. 

      SA node

    • E. 

      AV node

    Correct Answer
    D. SA node
    Explanation
    The SA node, also known as the sinoatrial node, is a small group of cells located in the right atrium of the heart. It is often referred to as the natural pacemaker of the heart because it initiates the electrical impulses that regulate the heart's rhythm. These electrical impulses cause the atria to contract and signal the AV node to continue the electrical conduction through the heart. Therefore, the SA node is responsible for setting the pace of the heart's contractions and ensuring that they occur in a coordinated manner.

    • D. 

      SA node

    • E. 

      AV node

    Correct Answer
    E. AV node
    Explanation
    The AV node, or atrioventricular node, is a small cluster of cells located in the lower part of the right atrium of the heart. It acts as a relay station between the atria and the ventricles, allowing for the coordinated contraction of the heart. When an electrical signal reaches the AV node, it briefly delays the signal before transmitting it to the ventricles. This delay allows for the atria to fully contract and fill the ventricles with blood before they contract. Therefore, the AV node plays a crucial role in regulating the heart's rhythm and ensuring efficient blood flow.

    • D. 

      SA node

    • E. 

      AV node

    Correct Answer
    A. Left/right bundle branches
    Explanation
    The left/right bundle branches are responsible for conducting electrical signals through the ventricles of the heart. They are part of the electrical conduction system and play a crucial role in coordinating the contraction of the ventricles, which pumps blood to the rest of the body. The left bundle branch carries the electrical signals to the left ventricle, while the right bundle branch carries them to the right ventricle. Dysfunction or blockage in these branches can lead to various heart conditions and abnormalities in the heart's rhythm.

    what is phase 0?

    • A. 

      K+ channels open, Ca++ flux in continues ("Plateau Phase" -- responsible for prolonging the cardiac action potential, making it longer than a nerve action potential)

    • B. 

      Rapid Na+ channels open (-85 mv), slow Ca++ channels open (-40 mv)

    • C. 

      K+ channels closed, Active transport of Na+ and K+ to return to resting state concentrations. (inward rectifier K+ channels)

    • D. 

      Na+ channels close = NA+ flux ceases (Outward Rectifier K+ channels open transiently)

    • E. 

      "Repolarization" Ca++ channels close, K+ flux out continues (delayed rectifier K+ channel)

    Correct Answer
    B. Rapid Na+ channels open (-85 mv), slow Ca++ channels open (-40 mv)
    Explanation
    In phase 0 of the cardiac action potential, the rapid Na+ channels open at a membrane potential of -85 mV, allowing a rapid influx of Na+ ions into the cell. At the same time, slow Ca++ channels open at a membrane potential of -40 mV, leading to a slower influx of Ca++ ions. This combination of ion channels opening contributes to the depolarization of the membrane and the initiation of the action potential.

      Na+ channels close = NA+ flux ceases (Outward Rectifier K+ channels open transiently)

    • E. 

      "Repolarization" Ca++ channels close, K+ flux out continues (delayed rectifier K+ channel)

    Correct Answer
    D. Na+ channels close = NA+ flux ceases (Outward Rectifier K+ channels open transiently)
    Explanation
    During phase 1 of the cardiac action potential, the rapid Na+ channels open, causing a rapid influx of Na+ ions into the cell, which depolarizes the membrane. At the same time, slow Ca++ channels also open, allowing a slower influx of Ca++ ions. This combination of Na+ and Ca++ fluxes is responsible for the "Plateau Phase" and prolongs the cardiac action potential. Towards the end of phase 1, the Na+ channels close, resulting in the cessation of Na+ flux. This closure of Na+ channels also triggers the transient opening of Outward Rectifier K+ channels, which allows K+ ions to leave the cell, contributing to the repolarization of the membrane.

    • E. 

      "Repolarization" Ca++ channels close, K+ flux out continues (delayed rectifier K+ channel)

    Correct Answer
    A. K+ channels open, Ca++ flux in continues ("Plateau Phase" -- responsible for prolonging the cardiac action potential, making it longer than a nerve action potential)
    Explanation
    During phase 2 of the cardiac action potential, K+ channels open and Ca++ flux continues. This phase is known as the "Plateau Phase" because it is responsible for prolonging the cardiac action potential and making it longer than a nerve action potential. The opening of K+ channels allows K+ ions to flow out of the cell, while the continued influx of Ca++ ions helps to maintain the depolarization of the cell membrane. This phase is crucial for the proper functioning of the heart and allows for coordinated contraction and relaxation of the cardiac muscles.

    • E. 

      "Repolarization" Ca++ channels close, K+ flux out continues (delayed rectifier K+ channel)

    Correct Answer
    E. "Repolarization" Ca++ channels close, K+ flux out continues (delayed rectifier K+ channel)
    Explanation
    During phase 3 of the cardiac action potential, the Ca++ channels close, leading to the repolarization of the cell. At the same time, the delayed rectifier K+ channels remain open, allowing K+ ions to continue flowing out of the cell. This outward flux of K+ ions helps to restore the cell to its resting state concentrations and contributes to the repolarization of the membrane potential.

    • E. 

      "Repolarization" Ca++ channels close, K+ flux out continues (delayed rectifier K+ channel)

    Correct Answer
    C. K+ channels closed, Active transport of Na+ and K+ to return to resting state concentrations. (inward rectifier K+ channels)
    Explanation
    During phase 4, the K+ channels are closed and there is active transport of Na+ and K+ ions to return to their resting state concentrations. This process is facilitated by inward rectifier K+ channels. This phase is important for maintaining the resting membrane potential and preparing the cardiac muscle for the next action potential.

    In the fetus blood flows from the  Right Atrium ->  Oval Foramen --> ___________

    • A. 

      Right ventricle

    • B. 

      Left atrium

    • C. 

      Descending aorta

    • D. 

      Left ventricle

    Correct Answer
    B. Left atrium
    Explanation
    In the fetus, blood flows from the right atrium to the left atrium through the Oval Foramen. This is because the Oval Foramen is a small opening between the two atria that allows blood to bypass the lungs, as they are not yet fully functional in the fetus. This allows oxygenated blood from the placenta to be directed towards the left atrium and then pumped out to the rest of the body through the left ventricle.
