Study Notes
Anatomy
- Focuses on the structure of the body and its parts, revealing relationships through dissection and imaging techniques.
- Subdivided into gross anatomy (large structures observable by the naked eye) and microscopic anatomy (study of small structures like cells and tissues).
Physiology
- Examines body functions and is categorized into specific subfields, including:
- Cell physiology
- Systems physiology
- Pathophysiology
- Exercise physiology
- Neurophysiology
- Endocrinology
- Cardiovascular physiology
- Immuno-physiology
- Respiratory physiology
- Renal physiology
- Reproductive physiology
Relationship between Anatomy and Physiology
- Interrelated disciplines; structure influences function, enabling the body to operate as a whole.
Structural Organization of Matter
- Chemical Level: Atoms (protons, neutrons, electrons) and molecules, with four key organic molecules:
- Proteins (20 amino acids)
- Complex carbohydrates (simple sugars)
- Nucleic acids (nucleotides)
- Lipids (fatty acids and glycerol)
- Cells: Smallest functional and structural units.
- Tissues: Groups of cells working together for specific functions.
- Organs: Composed of multiple tissues functioning collectively and having distinct shapes.
- Organ Systems: Collections of organs that perform common functions (e.g., integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, reproductive systems).
Basic Life Processes
- Digestion: Breaks down ingested food into absorbable molecules.
- Metabolism: Total biochemical processes, including energy release through breakdown of substances and ATP production.
- Excretion: Eliminating waste from the body via digestive, urinary, and integumentary systems.
- Responsiveness: Ability to detect and react to environmental changes, primarily managed by the nervous system.
- Movement: Activities enabled by muscular and skeletal systems, including the transport of fluids.
- Growth: Increase in cell number and size, regulated by hormones.
- Differentiation: Cells develop from unspecialized to specialized forms.
- Reproduction: Producing offspring or new cells for growth and repair.
Survival Needs
- Nutrients: Energy and structure provided by carbohydrates, proteins, and fats.
- Oxygen: Essential for energy-releasing chemical reactions.
- Water: Composes 60-80% of the body, crucial for secretion and excretion.
- Body Temperature: Optimal around 37°C (98°F); extremes can impair metabolism and threaten survival.
- Atmospheric Pressure: Affects breathing and gas exchange.
Homeostasis
- Dynamic equilibrium of internal environment managed by organ systems and feedback mechanisms.
- Primarily controlled by the nervous and endocrine systems; disruptions can lead to disease or death.
- Mild disruptions from environmental changes are common, but failure to restore homeostasis can have serious consequences.
- Nervous system detects changes and sends impulses; endocrine system regulates through hormone release.
