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
