    OR REVIEW THE FOLLOWING CLASS KNOWLEDGE BLOCKS


  • The body system that is responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body is:

    cardiovascular system

    Rationale: The cardiovascular system is made up of the heart, blood vessels, and blood. This system is responsible for transporting essential nutrients throughout the body, while removing gaseous waste from the body.

  • A collection of glands that produces hormones that regulate the body's growth and metabolism is part of the:

    endocrine system

    Rationale: The endocrine system is a complex system, that is made up of numerous organs that work to support the body in a variety of ways. The major organs of the endocrine system are the adrenal glands, the hypothalamus, the ovaries and testicles, the pancreas, the parathyroid glands, the pituitary glands, and the thymus. Each organ produces hormones that service the body in numerous ways, which include control of the nervous system, glucose and calcium levels, the immune system, and metabolism.

  • The body system that contains the largest organ, and protects deep tissues of the body from damage, while regulating body temperature and excreting waste is:

    integumentary system

    Rationale: The integumentary system contains the largest organ in the body, the skin. The primary purpose of this system is to protect all of the interior organs of the body from damage, while regulating body temperature and excreting waste. This system also allows the body to detect pain, pressure and temperature.

  • The body system that allows movement, and is made up of bones, muscles, tendons and cartilage is:

    musculoskeletal system

    Rationale: The musculoskeletal system gives the body the ability to move by using the skeleton of the body. The skeleton is made up of bones, muscles, tendons, and cartilage. This system provides support, stability, and movement to the body. The musculoskeletal system also protects helps to protect the internal organs of the body.

  • The body system that coordinates movements by sending signals from the brain to different parts of the body is:

    nervous system

    Rationale: The nervous system is made up of the central nervous system and the peripheral nervous system. The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of the somatic and autonomic nervous system. The main function of this system is to coordinate movements by sending signals from the brain to different parts of the body.

  • The body system that has the primary purpose of reproduction is:

    reproductive system

    Rationale: The reproductive system is made up of all the organs that allow the body to reproduce. These organs differ between males and females. The female reproductive system is a series of organs primarily located inside of the body, and include the vagina, uterus, and ovaries. The male reproductive system is a series of organs located outside of the body, and include the penis, testes, and scrotum. The reproductive system in males and females produces hormones to make reproduction possible.

  • The body system that involves breathing, and is responsible for supplying the blood with oxygen so it can be delivered to all parts of the body is:

    respiratory system

    Rationale: The respiratory system is made up of the organs that allow the body to breathe, which include the lungs, trachea, diaphragm, and bronchi. The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. When breathing, the body inhales oxygen and exhales carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood.

  • A system that is part of the nervous system, and is responsible for receiving stimulation from the environment and sending the information to the brain for processing is:

    sensory system

    Rationale: The sensory systems are a part of nervous system, and consists of sensory receptors that receive stimuli from the internal and external environment. The most common sensory systems are those for vision, hearing, taste, touch, and smell. These systems allow the body to receive a sensation, then sends the signal to the brain for interpretation through the sensory pathways.

  • The body system that eliminates waste from the body and maintains fluid/salt balances is:

    urinary system

    Rationale: The urinary system produces, stores, and eliminates urine. The organs of the urinary system are the kidneys, ureters, bladder and urethra. This system eliminates waste from the body through the urine, and helps to maintain the fluid and salt balances in the body.

  • The body system that consists of organs that break down the foods that we eat so they can be used for energy and repairing the body is:

    digestive system

    Rationale: Your digestive system consists of organs that break down food into components that your body uses for energy and for building and repairing cells and tissues. There are multiple organs in the digestive system, which include the stomach, liver, gallbladder, and intestines. The systems works to process foods we eat by breaking them down for use in the body, then expelling the waste from the body.
