    What is the correct name for the windpipe?

    • Trachea

    • Bronchi

    • Alveoli

    • Oseophagus

    Correct Answer
    A. Trachea
    Explanation
    The correct name for the windpipe is trachea. The trachea is a tube-like structure that connects the larynx to the bronchi, allowing air to pass in and out of the lungs. It is lined with ciliated cells and cartilage rings to provide support and prevent collapse. The trachea plays a vital role in the respiratory system by transporting air to and from the lungs.

    Low blood pressure is also known as :

    • Hypertension

    • Hypotension

    Correct Answer
    A. Hypotension
    Explanation
    Hypotension is the correct answer because it refers to low blood pressure. Hypotension occurs when the force of blood against the artery walls is too low, resulting in inadequate blood flow to the organs and tissues of the body. This can lead to symptoms such as dizziness, fainting, and fatigue. Hypertension, on the other hand, refers to high blood pressure, which is the opposite of low blood pressure.

    Which type of blood cell prevents excess blood loss and microbe entry?

    • Red

    • White

    • Platelet

    Correct Answer
    A. Platelet
    Explanation
    Platelets are responsible for preventing excess blood loss and microbe entry. They form clots to stop bleeding by sticking together and sealing off damaged blood vessels. Additionally, platelets release chemicals that attract white blood cells to the site of infection, helping to fight against microbes and prevent their entry into the body.

  • 7. 

    In which part of the respiratory system does gaseous exchange take place?

    • Bronchi

    • Trachea

    • Alveoli

    • Bronchioles

    Correct Answer
    A. Alveoli
    Explanation
    Gaseous exchange takes place in the alveoli. These tiny air sacs are located at the end of the bronchioles in the lungs. They are surrounded by a network of blood vessels called capillaries. Oxygen from the inhaled air diffuses through the thin walls of the alveoli and enters the bloodstream, while carbon dioxide, a waste product, diffuses from the bloodstream into the alveoli to be exhaled. This exchange of gases is crucial for the respiratory system to provide oxygen to the body's cells and remove carbon dioxide.

    Rate this question:

  • 8. 

    Which duct drains the most lymph?

    • Right lymphatic duct

    • Thoracic duct

    Correct Answer
    A. Thoracic duct
    Explanation
    The thoracic duct drains the most lymph in the body. It is the largest lymphatic vessel and collects lymph from the lower limbs, abdomen, left side of the thorax, left arm, and left side of the head and neck. It then empties into the left subclavian vein, where the lymph is returned to the bloodstream. The right lymphatic duct, on the other hand, drains lymph from the right side of the head and neck, right arm, and right side of the thorax, and empties into the right subclavian vein. However, the thoracic duct drains a larger portion of the body, making it the correct answer.

    Which part of the respiratory system contains the voicebox?

    • Epiglottis

    • Pharynx

    • Larynx

    Correct Answer
    A. Larynx
    Explanation
    The larynx is the part of the respiratory system that contains the voicebox. It is located between the pharynx and the trachea. The larynx houses the vocal cords, which are responsible for producing sound and allowing us to speak. It also plays a crucial role in protecting the airway during swallowing by closing off the entrance to the trachea with the epiglottis.

    Which type of blood vessel allows for exchange of materials with the body's tissues?

    • Artery

    • Vein

    • Capillary

    Correct Answer
    A. Capillary
    Explanation
    Capillaries are the smallest blood vessels in the body and are responsible for the exchange of materials between the bloodstream and the body's tissues. Their thin walls allow for the diffusion of oxygen, nutrients, and waste products between the blood and the surrounding tissues. Arteries and veins are larger blood vessels that transport blood to and from the capillaries, but they do not directly participate in the exchange of materials.

    • Leg

    • Arm

    • Head

    • Neck

    Correct Answer
    A. Neck
    Explanation
    The external jugular vein is found in the neck. It is a prominent vein that runs diagonally across the side of the neck and is visible under the skin. It drains blood from the head, face, and neck region and carries it back to the heart. The external jugular vein is often used for medical procedures such as blood draws or intravenous access.

    Rate this question:

  • 15. 

    In which type of blood vessel are valves found?

    • Artery

    • Vein

    • Capillary

    Correct Answer
    A. Vein
    Explanation
    Valves are found in veins. Veins are blood vessels that carry deoxygenated blood back to the heart. Valves in veins help prevent the backflow of blood and ensure that blood flows in one direction, towards the heart. This is important because veins are under lower pressure compared to arteries, and the valves help to maintain the flow of blood against gravity.

    Rate this question:

  • 16. 

    Which type of blood vessel is under the most pressure?

    • Artery

    • Vein

    • Capillary

    Correct Answer
    A. Artery
    Explanation
    Arteries are the type of blood vessels that are under the most pressure. This is because arteries carry oxygenated blood away from the heart to the rest of the body, and the force exerted by the pumping of the heart causes the blood to flow with high pressure. In contrast, veins carry deoxygenated blood back to the heart, and capillaries are tiny, thin-walled vessels that connect arteries and veins, allowing for the exchange of nutrients and waste products.

    Rate this question:

  • 17. 

    Which part of the lymphatic system filters lymph to trap or remove any harmful micro-organisms?

    • Nodes

    • Ducts

    • Vessels

    • Capillaries

    Correct Answer
    A. Nodes
    Explanation
    Nodes are small, bean-shaped structures found throughout the lymphatic system. They act as filters, trapping and removing harmful microorganisms, as well as other foreign substances, from the lymph fluid. This helps to prevent the spread of infection and disease throughout the body.

    In which part of the body is the common carotid artery found?

    • Neck

    • Head

    • Arm

    • Leg

    Correct Answer
    A. Neck
    Explanation
    The common carotid artery is found in the neck. This artery is a major blood vessel that supplies oxygenated blood to the head and neck region. It branches off into the internal and external carotid arteries, which further supply blood to the brain and face, respectively. The location of the common carotid artery in the neck allows for efficient and direct blood flow to these vital areas.

    Rate this question:

  • 19. 

    Which type of blood vessel lies deeper in the body?

    • Artery

    • Vein

    • Capillary

    Correct Answer
    A. Artery
    Explanation
    Arteries are a type of blood vessel that carry oxygenated blood away from the heart to the various organs and tissues in the body. They are deeper in the body compared to veins and capillaries, which are closer to the surface. Arteries have thicker walls and a more muscular structure to withstand the high pressure of blood flow. Veins, on the other hand, carry deoxygenated blood back to the heart and have thinner walls. Capillaries are the smallest blood vessels and connect arteries to veins, allowing for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.

    Rate this question:

  • 20. 

    Which pathology causes inflammation inside of a vein?

    • Deep vein thrombosis

    • Phlebitis

    • Anaemia

    • Epitaxis

    Correct Answer
    A. Phlebitis
    Explanation
    Phlebitis is the inflammation of a vein, which can occur due to various factors such as infection, trauma, or the presence of a blood clot. This inflammation can cause pain, redness, and swelling in the affected area. Deep vein thrombosis, on the other hand, refers to the formation of a blood clot in a deep vein, which can also lead to inflammation but is not the primary cause. Anaemia and epitaxis do not directly cause inflammation inside a vein. Therefore, phlebitis is the correct answer as it specifically refers to the pathology causing inflammation inside a vein.

    Rate this question:

  • 21. 

    Which system carries enzymes to the appropriate cells?

    • Cardiovascular

    • Lymphatic

    Correct Answer
    A. Cardiovascular
    Explanation
    The cardiovascular system carries enzymes to the appropriate cells. This system consists of the heart, blood vessels, and blood. The heart pumps blood, which contains enzymes, to all the cells in the body through the blood vessels. This ensures that the enzymes reach the appropriate cells where they are needed for various biological processes. The lymphatic system, on the other hand, is responsible for carrying lymph fluid and immune cells, not enzymes.
