Study Notes

Anatomy and Physiology Overview

Anatomy investigates body structure and has two main approaches: systemic anatomy (by systems) and regional anatomy (by areas).
Internal structures of a living person can be examined through surface anatomy (external features) and anatomical imaging (x-rays, ultrasound, MRI).
Microscopic anatomy includes cytology (study of cells) and histology (study of tissues).
Developmental anatomy examines changes from conception to physical maturity.

Structural and Functional Organization of the Human Body

Life's structural hierarchy: chemical → atoms → cells → tissue → organ → organ system → organism.
Cells are the fundamental units of organisms, containing organelles that perform specific functions.
Tissues consist of similar cells and four main types: epithelial, connective, muscle, and nervous.
Organs are made of two or more tissue types performing common functions.
Organ systems consist of groups of organs working together, with eleven major systems:
- Integumentary system: protection, temperature regulation, vitamin D production.
- Skeletal system: protection, support, movement, blood cell production, mineral storage.
- Muscular system: body movement, posture, heat production.
- Nervous system: sensation detection, movement control, physiological processes.
- Endocrine system: regulates metabolism, growth, reproduction.
- Cardiovascular system: nutrient transport, waste removal, immune response.
- Lymphatic system: removes foreign substances, disease combat, fluid balance.
- Respiratory system: oxygen and carbon dioxide exchange, blood pH regulation.
- Digestive system: digestion processes, nutrient absorption, waste elimination.
- Urinary system: waste removal, blood pH and ion balance.
- Reproductive system: female (oocyte production, fetal development), male (sperm production).

Characteristics of Life

Organization: interrelationships between parts of an organism enabling function.
Metabolism: energy use for growth, movement, and reproduction.
Responsiveness: ability to sense and adjust to environmental changes (irritability).
Movement: positional change of a body or part.
Growth: increase in size or cell number leading to overall enlargement.
Development: changes from fertilization to death, including differentiation and adaptation.
Reproduction: formation of new cells or organisms.

Homeostasis

Homeostasis: maintenance of a stable internal environment.
Negative feedback mechanism counteracts deviations from set points:
- Process: stimulus → receptor → input (afferent) → output (efferent) → response.
