    Red blood cells

    • Erythrocyte

    • Melanocyte

    • Leukocyte

    • Erithrocyte

    Correct Answer
    A. Erythrocyte
    Explanation
    The correct answer is erythrocyte. Erythrocytes, also known as red blood cells, are responsible for carrying oxygen from the lungs to the rest of the body. They contain a protein called hemoglobin, which binds to oxygen and allows for its transportation. Erythrocytes lack a nucleus and other organelles, allowing for more space to carry hemoglobin. This specialization enables them to efficiently perform their main function of oxygen transport. Melanocytes are responsible for producing melanin, which gives color to the skin, hair, and eyes. Leukocytes are white blood cells involved in the immune response. Erithrocyte is a misspelling of erythrocyte.

    Rate this question:

  • 11. 

     Percentage of red blood cells in a given volume of blood.

    • Erythrocyte sedimentation rate

    • Differentiation

    • Hematocrit

    • Complete blood count

    Correct Answer
    A. Hematocrit
    Explanation
    Hematocrit is a measure of the percentage of red blood cells in a given volume of blood. It is used to evaluate the blood's ability to deliver oxygen to the body's tissues. A higher hematocrit level indicates a higher concentration of red blood cells, which can be an indication of conditions such as dehydration or polycythemia. Conversely, a lower hematocrit level may suggest anemia or blood loss. Therefore, hematocrit is an important component of a complete blood count, which is a routine blood test that provides valuable information about a person's overall health and blood status.

    Group of inherited disorders marked by progressive weakness and degeneration of muscle fibers.

    • Osteodystrophy

    • Myopathy

    • Muscular dystrophy

    • Rheumatoid arthritis

    Correct Answer
    A. Muscular dystrophy
    Explanation
    Muscular dystrophy is a group of inherited disorders characterized by progressive weakness and degeneration of muscle fibers. This condition leads to the deterioration of muscle strength and function over time. It is caused by mutations in specific genes that are involved in the production of proteins necessary for muscle structure and function. Symptoms typically appear in childhood and may include muscle weakness, difficulty walking, and loss of muscle mass. There is currently no cure for muscular dystrophy, but treatments can help manage symptoms and improve quality of life.

    • Polymyositis

    • Rheumatoid arthritis

    • Synovitis

    Correct Answer
    A. Osteoarthritis
    Explanation
    Osteoarthritis is the correct answer because it is a condition characterized by inflammation of bones and joints with degeneration of cartilage in the joint space. This condition primarily affects the elderly and is commonly caused by wear and tear over time, leading to pain, stiffness, and reduced mobility in the affected joints. Unlike rheumatoid arthritis, which is an autoimmune disease, osteoarthritis is not caused by an immune system dysfunction. Polymyositis refers to inflammation of multiple muscles, while synovitis refers to inflammation of the synovial membrane lining the joints.

    • Osteoarthritis

    • Arthritis

    Correct Answer
    A. Osteomyelitis
    Explanation
    Osteomyelitis is the correct answer because it refers to the inflammation of bone and bone marrow. This condition is usually caused by an infection, commonly by bacteria, that spreads to the bone. It can lead to pain, swelling, and redness in the affected area, and if left untreated, it can cause bone destruction and other complications. Osteomyelitis is different from osteoarthritis and arthritis, which involve inflammation of the joints rather than the bone itself.
