    Study Notes

    Nutrition

    • The process of obtaining and utilizing energy and nutrients from food
    • Includes:
      • Ingestion: taking in food and water
      • Digestion: breaking down food into smaller molecules
      • Absorption: absorbing nutrients into the bloodstream
      • Assimilation: using nutrients for energy and growth
      • Egestion: removing waste products

    Respiration

    • The process of obtaining energy from the breakdown of glucose and other organic molecules
    • Includes:
      • Breathing: taking in oxygen and releasing carbon dioxide
      • Cellular respiration: converting glucose into energy (ATP)
      • Fermentation: anaerobic respiration, occurs in the absence of oxygen

    Transportation

    • The process of moving substances and oxygen throughout the body
    • Includes:
      • Blood circulation: transportation of oxygen and nutrients to cells
      • Lymphatic system: defense against disease and infection

    Excretion

    • The process of removing waste and excess substances from the body
    • Includes:
      • Urine formation: removal of waste and excess substances through the kidneys
      • Defecation: removal of waste through the digestive system
      • Perspiration: removal of excess heat and water through the skin

    Regulation and Control

    • The process of maintaining homeostasis and responding to stimuli
    • Includes:
      • Nervous system: transmission and processing of information
      • Endocrine system: production and regulation of hormones
      • Feedback mechanisms: regulation of body processes to maintain homeostasis

    Movement and Locomotion

    • The process of movement and change in position
    • Includes:
      • Muscular system: contraction and relaxation of muscles
      • Skeletal system: support and movement of the body

    Growth and Development

    • The process of growth, development, and reproduction
    • Includes:
      • Cell division: growth and development of tissues
      • Differentiation: specialization of cells and tissues
      • Reproduction: production of offspring

    Nutrition

    • Ingestion involves taking in food and water, which is then broken down into smaller molecules during digestion
    • Absorption of nutrients into the bloodstream occurs through the walls of the intestines
    • Assimilation is the process of using absorbed nutrients for energy and growth
    • Egestion involves the removal of waste products from the body

    Respiration

    • Breathing involves the inhalation of oxygen and exhalation of carbon dioxide
    • Cellular respiration is the process of converting glucose into energy (ATP) in the presence of oxygen
    • Fermentation is a type of anaerobic respiration that occurs in the absence of oxygen

    Transportation

    • Blood circulation involves the transportation of oxygen and nutrients to cells throughout the body
    • The lymphatic system plays a crucial role in defense against disease and infection

    Excretion

    • Urine formation involves the removal of waste and excess substances through the kidneys
    • Defecation is the removal of waste through the digestive system
    • Perspiration helps to remove excess heat and water from the body through the skin

    Regulation and Control

    • The nervous system is responsible for the transmission and processing of information
    • The endocrine system produces and regulates hormones that control various bodily functions
    • Feedback mechanisms help to regulate body processes to maintain homeostasis

    Movement and Locomotion

    • The muscular system involves the contraction and relaxation of muscles to facilitate movement
    • The skeletal system provides support and movement to the body through the contraction of muscles

    Growth and Development

    • Cell division is essential for growth and development of tissues
    • Differentiation is the process by which cells and tissues specialize
    • Reproduction involves the production of offspring through the combination of genetic material
