    Study Notes

    Body Systems

    • The Renal/Urinary system filters waste and excess fluids from the blood, regulating electrolyte levels and maintaining acid-base balance.
    • The Circulatory system transports oxygen, nutrients, and hormones throughout the body.
    • The Digestive system breaks down ingested food into nutrients for energy, growth, and repair.
    • The Nervous system initiates and regulates vital body functions, sensation, and body movements.
    • The Integumentary system provides a protective barrier, regulates body temperature, and aids in the senses of touch and feel.
    • The Endocrine system produces hormones to regulate a wide variety of bodily functions, including growth, metabolism, and reproductive processes.

    Skeletal System

    • The Skeletal system serves as a support structure for the body, gives the body its shape, produces blood cells, provides protection for organs, and stores minerals.

    Cell Types

    • Red blood cells are associated with the Circulatory system.

    Organisms

    • Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis.
    • Birds have the pelvis bone, which is involved in holding, walking, swimming, and flying.

    Reproduction

    • Sexual reproduction involves meiosis, the process of gamete formation.
    • Asexual reproduction involves stolon, a type of vegetative propagation.

    Adaptations

    • Clinging adaptations, such as claws or tendrils, help organisms hang onto whatever they are climbing.
    • Webbed feet are an adaptation that helps organisms swim and search for food, found in ducks and other aquatic birds.
    • Large eyes are an adaptation that helps organisms see at night while they hunt, found in nocturnal animals such as owls.

    Regulation

    • The brain is responsible for regulation in the body, controlling various functions such as movement, sensation, and cognition.
