Study Notes
Life Processes
Nutrition
- Ingestion: Taking in food and nutrients
- Digestion: Breaking down food into smaller molecules
- Absorption: Taking in nutrients through the bloodstream
- Assimilation: Using nutrients for energy, growth, and repair
- Egestion: Eliminating waste products
Respiration
- Breathing: Taking in oxygen and expelling carbon dioxide
-
Cellular Respiration: Converting glucose into energy (ATP) through cellular processes
- Aerobic Respiration: Occurs in presence of oxygen, produces ATP and water
- Anaerobic Respiration: Occurs in absence of oxygen, produces ATP and lactic acid
Transportation
-
Circulatory System: Transports oxygen, nutrients, and waste products throughout the body
- Heart: Pumps blood throughout the body
- Blood Vessels: Arteries, veins, and capillaries transport blood
- Blood: Carries oxygen, nutrients, and waste products
Regulation and Control
-
Nervous System: Coordinates and regulates body functions
- Central Nervous System: Brain and spinal cord
- Peripheral Nervous System: Nerves and sensory receptors
-
Endocrine System: Produces and regulates hormones
- Hormones: Chemical messengers that regulate body functions
Excretion
- Kidneys: Filter waste and excess substances from the blood
- Liver: Detoxifies and breaks down substances
- Skin: Removes waste through sweating
- Lungs: Exhale carbon dioxide and other gases
Growth and Development
- Cell Division: Cells divide to produce new cells
- Cell Differentiation: Cells become specialized for specific functions
- Tissue Growth: Tissues grow and develop through cell division and differentiation
- Organ Growth: Organs develop and grow through tissue growth and differentiation
Test your knowledge of the various life processes, including nutrition, respiration, transportation, regulation, excretion, and growth and development. Covering key concepts and processes that occur within living organisms.
