    Study Notes

    Integumentary System

    • Forms the external body covering, including skin, hair, and fingernails
    • Waterproofs the body
    • Acts as a physical barrier to protect the body from invading pathogens and injury
    • Produces vitamin D with the help of sunlight
    • Excretes salts in perspiration
    • Helps regulate body temperature
    • Location of cutaneous nerve receptors

    Skeletal System

    • Consists of bones, cartilages, ligaments, and joints
    • Gives the body structural framework
    • Provides muscle attachment for movement
    • Protects vital organs
    • Site of blood cell formation
    • Stores minerals

    Muscular System

    • Consists of skeletal muscles attached to the skeleton
    • Produces movement of bones
    • Supports and stabilizes certain body structures
    • Generates heat for the body (a byproduct of contraction)

    Nervous System

    • Consists of the brain, spinal cord, nerves, and sensory receptors
    • Responds to internal and external stimuli
    • Sensory receptors detect changes
    • Messages are sent to the central nervous system
    • Central nervous system assesses information and activates effectors (muscles and glands)

    Endocrine System

    • Comprised of many glands that secrete chemical messengers (hormones) into the blood
    • Works closely with the Nervous System to regulate and control bodily functions
    • Body functions controlled by hormones include growth, reproduction, and use of nutrients
    • Endocrine glands include the hypothalamus, pituitary gland, thyroid and parathyroids, adrenal glands, thymus, pancreas, pineal gland, and ovaries (females) and testes (males)

    Cardiovascular System

    • Includes the heart, blood, and blood vessels
    • Heart pumps blood
    • Vessels transport blood to tissues
    • Pumps and transports blood around the body, containing oxygen, carbon dioxide, nutrients, hormones, and metabolic waste products

    Lymphatic System

    • Includes lymph, lymphatic vessels, lymph nodes, and lymphoid organs (spleen, thymus, MALT tissue)
    • Re-absorbs leaked fluids from the extracellular spaces and returns it back to the bloodstream
    • Absorbs lipids and lipid-soluble vitamins directly from the digestive tract
    • Plays a huge role in immune function

    Respiratory System

    • Includes the nasal passages, pharynx, larynx, trachea, bronchi, and lungs
    • Gases are exchanged with the blood through air sacs (alveoli) in the lungs
    • Supplies the body with necessary oxygen (absorption)
    • Removes carbon dioxide (excretion)

    Digestive System

    • Includes the oral cavity (mouth), esophagus, stomach, small and large intestines, rectum, and accessory organs
    • Breaks down and digests food
    • Allows for nutrient absorption into blood
    • Eliminates indigestible material as feces

    Urinary System

    • Includes the kidneys, ureters, urinary bladder, and urethra
    • Eliminates nitrogenous wastes
    • Maintains acid-base balance
    • Regulates water and electrolyte balance
    • Helps regulate blood pressure
