    Study Notes

    Body Systems

    • A system is a group of parts that work together to perform specific functions.
    • The human body has ten different systems that work together to keep us healthy and functional.

    Nervous System

    • The nervous system consists of the brain, spinal cord, and nerves.
    • The brain is the control center of the body, sending signals through the spinal cord to nerves all around the body.
    • Nerves are cables that help move signals around to different parts of the body, controlling functions like breathing and blinking.

    Respiratory System

    • The respiratory system provides the body with oxygen through breathing.
    • Air enters the nose and mouth, passes through the trachea in the throat, and enters the lungs.
    • In the lungs, oxygen is transferred to the blood, which is then circulated throughout the body.
    • Oxygen is essential for powering the body's functions.

    Cardiovascular System

    • The cardiovascular system consists of the heart and blood vessels (tubes that carry blood).
    • The heart pumps blood throughout the body, delivering oxygen and nutrients and helping to protect against diseases.
    • Blood vessels carry blood to all parts of the body.

    Digestive System

    • The digestive system breaks down food into nutrients, absorbs them, and eliminates waste.
    • Major parts of the digestive system include the stomach and intestines.
    • Nutrients are absorbed from food and circulated throughout the body, providing energy and essential substances.

    Musculoskeletal System

    • The musculoskeletal system consists of bones and muscles.
    • Bones support the body, protect organs, and produce blood cells.
    • Muscles are connected to bones, receiving messages from the brain through nerves, and facilitating movement by pulling on bones.
    • The largest muscle in the body is the gluteus maximus, which is used for sitting.
