    The organs that make up the endocrine system are called ___.

    • A.

      Hormones

    • B.

      Glands

    • C.

      Lymph nodes

    • D.

      Leukocytes

    Correct Answer
    B. Glands
    Explanation
    The organs that make up the endocrine system are called glands. Glands are specialized organs that produce and release hormones into the bloodstream. These hormones then travel to target cells or organs, where they regulate various bodily functions and processes. Examples of glands in the endocrine system include the pituitary gland, thyroid gland, adrenal glands, and pancreas.

    Rate this question:

  • 2. 

    The endocrine system:

    • A.

      Affects only the reproductive system.

    • B.

      Releases hormones into the bloodstream.

    • C.

      Competes with the nervous system.

    • D.

      Is made up primarily of glands with ducts.

    Correct Answer
    B. Releases hormones into the bloodstream.
    Explanation
    The endocrine system releases hormones into the bloodstream. Unlike the reproductive system, it is not limited to affecting only one system in the body. The endocrine system works in coordination with the nervous system rather than competing with it. It is primarily composed of glands that do not have ducts, allowing hormones to be released directly into the bloodstream for distribution throughout the body.

    Which physiological organ system includes the lungs, trachea, pharynx, and diaphragm?

    • A.

      Nervous

    • B.

      Endocrine

    • C.

      Respiratory

    • D.

      Cardiovascular/circulatory

    • E.

      Digestive

    Correct Answer
    C. Respiratory
    Explanation
    The respiratory system includes the lungs, trachea, pharynx, and diaphragm. This system is responsible for the exchange of oxygen and carbon dioxide in the body. The lungs are the main organs involved in respiration, while the trachea and pharynx help in the passage of air. The diaphragm is a muscle that aids in the process of breathing. Therefore, the correct answer is respiratory.

    Rate this question:

    Which of the following is NOT a function of the respiratory system?

    • A.

      In the alveoli of the lungs, oxygen diffuses into the blood

    • B.

      Oxygen is inhaled and carbon dioxide is exhaled through the mouth and nose

    • C.

      In the alveoli of the lungs, carbon dioxide is diffuses out of the blood

    • D.

      Absorption and recirculation of lymph into the blood stream

    Correct Answer
    D. Absorption and recirculation of lymph into the blood stream
    Explanation
    The respiratory system is responsible for the exchange of gases, specifically oxygen and carbon dioxide, between the body and the environment. Oxygen is inhaled and carbon dioxide is exhaled through the mouth and nose. In the alveoli of the lungs, oxygen diffuses into the blood while carbon dioxide diffuses out of the blood. However, absorption and recirculation of lymph into the bloodstream is not a function of the respiratory system. Lymph is a clear fluid that contains white blood cells and is responsible for removing waste and toxins from the body, but it is not directly related to the respiratory system.

      Ureters

    • D.

      Intestines

    • E.

      Liver

    Correct Answer
    A. Kidneys
    Explanation
    The kidneys are the main organs of the excretory/urinary system. They play a crucial role in filtering waste products, excess water, and toxins from the blood to produce urine. The urine is then transported to the bladder through the ureters for storage until it is eliminated from the body. The lungs are not part of the excretory/urinary system; their main function is to exchange gases. The intestines are responsible for digestion and absorption of nutrients, while the liver is involved in detoxification and metabolism of various substances.

    Rate this question:

    • A.

      Break down nutrients.

    • B.

      Remove wastes.

    • C.

      Absorb nutrients.

    • D.

      Prevent infection.

    Correct Answer
    B. Remove wastes.
    Explanation
    The excretory/urinary system is responsible for removing waste products from the body. It filters out waste materials, such as toxins and excess water, from the bloodstream and eliminates them through urine. This helps maintain the balance of fluids, electrolytes, and pH levels in the body, thus contributing to overall homeostasis. The system does not break down nutrients, absorb nutrients, or prevent infection, as those functions are carried out by other systems in the body.
