    What are the two functions of the lymphatic system?

    • A.

      Maintain proper fluid balance

    • B.

      Defend against infection

    • C.

      To protect the lungs

    • D.

      To eliminate carbon dioxide from the body

    Correct Answer(s)
    A. Maintain proper fluid balance
    B. Defend against infection
    Explanation
    The lymphatic system has two main functions. The first function is to maintain proper fluid balance in the body. It does this by collecting excess fluid, called lymph, from the tissues and returning it to the bloodstream. This helps prevent the buildup of fluid and swelling in the tissues. The second function of the lymphatic system is to defend against infection. It does this by producing and transporting white blood cells, called lymphocytes, which help fight off pathogens and foreign substances in the body. These two functions work together to support the overall health and immune system of the body.

      Apocrine

    Correct Answer
    A. Infection fighting organisms
    Explanation
    Macrophages are a type of white blood cell that play a crucial role in the immune system's response to infections. They are responsible for engulfing and destroying foreign invaders, such as bacteria and viruses, through a process called phagocytosis. Macrophages are found in various tissues throughout the body and are an essential part of the body's defense against pathogens.

    The layer of the epidermis that is next to the deepest layer is the

    • A.

      Stratum basale

    • B.

      Stratum corneum

    • C.

      Stratum spinosum

    • D.

      Stratum granulosum

    Correct Answer
    C. Stratum spinosum
    Explanation
    The stratum spinosum is the layer of the epidermis that is next to the deepest layer. It is located above the stratum basale and below the stratum granulosum. The stratum spinosum is responsible for providing strength and flexibility to the skin. It contains several layers of cells that are connected by desmosomes, which give the layer a spiny appearance under a microscope. These cells continue to divide and differentiate as they move towards the surface of the skin, eventually becoming the outermost layer of the epidermis.

    Which glands play a role in keeping the hair and skin soft and waterproof?

    • A.

      Sebaceous

    • B.

      Apocrine

    • C.

      Eccrine

    • D.

      Sweat

    Correct Answer
    A. Sebaceous
    Explanation
    Sebaceous glands play a role in keeping the hair and skin soft and waterproof. These glands are responsible for producing sebum, an oily substance that moisturizes and lubricates the skin and hair. Sebum helps to keep the skin soft and supple, while also providing a waterproof barrier that helps to prevent excessive moisture loss. Therefore, the sebaceous glands are essential for maintaining the health and appearance of the hair and skin.

    Pigmentation is attributed to

    • A.

      Melanin

    • B.

      Dermal cells

    • C.

      Subcutaneous cell

    • D.

      Sebaceous gland secretions

    Correct Answer
    A. Melanin
    Explanation
    Melanin is responsible for pigmentation. It is a pigment produced by specialized cells called melanocytes, which are located in the skin, hair follicles, and other parts of the body. Melanin determines the color of our skin, hair, and eyes. It provides protection against the harmful effects of ultraviolet (UV) radiation from the sun by absorbing and dispersing the UV rays. The amount and type of melanin produced by melanocytes vary among individuals, leading to different skin tones and colors.

    • B.

      Melanin

    • C.

      Adipose

    • D.

      Pigmentation

    Correct Answer
    B. Melanin
    Explanation
    Melanocytes are specialized cells found in the skin that produce a pigment called melanin. Melanin is responsible for the color of our hair, skin, and eyes. It provides protection against the harmful effects of UV radiation from the sun by absorbing and scattering the rays. The amount and type of melanin produced by melanocytes determine an individual's skin color. Therefore, melanin is the correct answer as it accurately describes the substance produced by melanocytes.

    • D.

      Involuntary; non striated

    Correct Answer
    A. Voluntary; striated
    Explanation
    Skeletal muscle is classified as voluntary because it is under conscious control. This means that we have the ability to control its movements. Additionally, skeletal muscle is classified as striated because it has a striped or banded appearance under a microscope. These stripes are caused by the arrangement of the muscle fibers.

    C. Syndesmosis
    Explanation
    A syndesmosis joint is a type of joint that connects the distal end of the tibia and fibula. It is characterized by the presence of a fibrous membrane called the interosseous membrane, which holds the two bones together. Unlike other types of joints, such as condyloid, gomphosis, and synchondrosis, a syndesmosis joint allows for limited movement between the tibia and fibula, providing stability and support to the lower leg.
