    The major artery that supplies the upper arm is called the:

    • A.

      Brachial

    • B.

      Carotid

    • C.

      Ulnar

    • D.

      Iliac

    Correct Answer
    A. Brachial
    Explanation
    The correct answer is "brachial." The brachial artery is the major artery that supplies blood to the upper arm. It runs along the inner side of the arm and is responsible for delivering oxygenated blood to the muscles and tissues of the upper arm. The carotid artery supplies blood to the head and neck, the ulnar artery supplies blood to the forearm and hand, and the iliac artery supplies blood to the pelvis and lower limbs.

    • B.

      Dorsalis pedis

    • C.

      Ilnar

    • D.

      Carotid

    Correct Answer
    A. Popliteal
    Explanation
    The major artery that supplies the knee is called the popliteal artery. This artery is located behind the knee and is responsible for delivering oxygenated blood to the muscles and tissues in the knee region. It is a continuation of the femoral artery and plays a crucial role in maintaining proper blood flow to the lower leg and foot.

      Dorsalis pedis

    • B.

      Popliteal

    • C.

      Iliac

    • D.

      Renal

    Correct Answer
    A. Dorsalis pedis
    Explanation
    The dorsalis pedis is the major artery that supplies blood to the foot. It is located on the top of the foot, just below the ankle joint. This artery is responsible for delivering oxygenated blood to the foot and toes, allowing for proper circulation and function. The popliteal artery is located behind the knee and supplies blood to the lower leg and calf muscles. The iliac artery is located in the pelvis and supplies blood to the lower abdomen, pelvis, and legs. The renal artery supplies blood to the kidneys.

    The major vein that drains the upper arm is called the:

    • A.

      Jugular

    • B.

      Brachial

    • C.

      Cephalic

    • D.

      Femoral

    Correct Answer
    B. Brachial
    Explanation
    The correct answer is brachial. The brachial vein is the major vein that drains the upper arm. It runs alongside the brachial artery and is responsible for carrying deoxygenated blood back to the heart. The jugular vein, on the other hand, is located in the neck and drains blood from the head and neck region. The cephalic vein is found in the upper arm but is not the major vein responsible for draining it. The femoral vein is located in the thigh and drains blood from the lower limb.

    The major vein that drains the head and brain is called the:

    • A.

      Jugular

    • B.

      Vertebral

    • C.

      Cephalic

    • D.

      Ulnar

    Correct Answer
    A. Jugular
    Explanation
    The jugular vein is the major vein that drains the head and brain. It is responsible for carrying deoxygenated blood from the brain back to the heart. The other options, vertebral, cephalic, and ulnar, are not major veins that drain the head and brain. The vertebral vein drains the spinal cord, the cephalic vein drains the upper extremities, and the ulnar vein drains the forearm and hand. Therefore, the correct answer is jugular.

    The major vein that drains the liver is called the:

    • A.

      Hepatic

    • B.

      Axillary

    • C.

      Ulnar

    • D.

      Femoral

    Correct Answer
    A. Hepatic
    Explanation
    The major vein that drains the liver is called the hepatic vein. This vein carries deoxygenated blood from the liver to the inferior vena cava, which then returns the blood to the heart. The hepatic vein plays a crucial role in maintaining proper blood circulation and functioning of the liver.

    The major vein that drains the kidneys is called the:

    • A.

      Hepatic

      Renal

    • C.

      Cephalic

    • D.

      Femoral

    Correct Answer
    B. Renal
    Explanation
    The correct answer is renal. The renal vein is the major vein that drains the kidneys. It carries deoxygenated blood from the kidneys to the inferior vena cava, which then carries the blood back to the heart. The hepatic vein drains the liver, the cephalic vein is located in the upper arm, and the femoral vein is found in the thigh.

    The major vein that drains the pelvis is called the:

    • A.

      Common iliac

    • B.

      Hepatic

    • C.

      Renal

    • D.

      Ulnar

    Correct Answer
    A. Common iliac
    Explanation
    The common iliac vein is the correct answer because it is the major vein that drains the pelvis. It receives blood from the internal and external iliac veins and eventually merges with the opposite side to form the inferior vena cava. The hepatic vein drains blood from the liver, the renal vein drains blood from the kidneys, and the ulnar vein is located in the arm and drains blood from the hand and forearm.

    The point at which air enters the respiratory tract is called the:

    • A.

      Larynx

    • B.

      Lung

    • C.

      Nasal cavity

    • D.

      Bronchus

    Correct Answer
    C. Nasal cavity
    Explanation
    The correct answer is nasal cavity because it is the point at which air enters the respiratory tract. The nasal cavity is located behind the nose and is responsible for filtering, warming, and humidifying the air before it reaches the lungs. It also contains tiny hairs called cilia that help trap dust, pollen, and other particles, preventing them from entering the lungs.

    The wind pipe which conducts air between the larynx and lungs is called the:

    • A.

      Larynx

    • B.

      Pharynx

    • C.

      Trachea

    • D.

      Larynx

    Correct Answer
    C. Trachea
    Explanation
    The windpipe, also known as the trachea, is the correct answer. It is the tube that connects the larynx (voice box) to the lungs and allows air to pass into and out of the respiratory system. The larynx is a part of the respiratory system, but it is not responsible for conducting air between the larynx and lungs. The pharynx is the part of the throat that connects the nasal and oral cavities to the larynx and esophagus.

    The divisions of the trachea which enter the lungs are called the:

    • A.

      Pharynx

    • B.

      Trachea

    • C.

      Bronchi

    • D.

      Larynx

    Correct Answer
    C. Bronchi
    Explanation
    The divisions of the trachea that enter the lungs are called bronchi. The trachea is a tube that connects the throat to the lungs, and it divides into two bronchi, one for each lung. The bronchi further divide into smaller tubes called bronchioles, which eventually lead to the air sacs in the lungs called alveoli. The bronchi are responsible for carrying air in and out of the lungs, allowing for the exchange of oxygen and carbon dioxide. The other options, pharynx, larynx, and trachea, are all parts of the respiratory system but are not specifically the divisions of the trachea that enter the lungs.
