Study Notes
Anatomy and Physiology
- Anatomy investigates the structure of the body; physiology studies the processes or functions of living organisms.
- Two basic approaches to anatomy: gross anatomy (macroscopic) and microscopic anatomy (cell and tissue level).
Terminology and Concepts
- Pathos, physis, and logos are Greek terms relating to disease processes: pathos (suffering), physis (nature), logos (study).
- Pathophysiology examines abnormal changes in body functions due to disease.
Basic Biological Units
- Atoms, such as hydrogen and carbon, combine to form molecules.
- Molecules create organelles, which make up cells — the basic structural and functional units of organisms.
- Tissues consist of groups of similar cells and the material surrounding them.
Tissue Types
- Four primary tissue types: epithelial, connective, muscle, and nervous.
- Organs are composed of two or more tissue types working together for common functions.
Levels of Organization
- An organism is a complete living entity, which can be unicellular or multicellular.
- The organization level in biology includes interactions of cell organelles, cells, tissues, organs, and systems.
Life Processes
- Vital functions include energy utilization for growth, movement, and reproduction.
- Homeostasis is the body's ability to maintain a stable internal environment despite external changes.
Growth and Development
- Growth can result from an increase in cell number, size, or surrounding substance.
- Development involves changes over time, including differentiation — the process by which cells become specialized.
Regulatory Systems
- The Nervous and Endocrine systems regulate homeostasis, controlling body temperature through mechanisms like sweating or shivering.
- Various organ systems provide protection, support, movement, and maintenance of body functions.
Organ System Functions
- Integumentary system: protects, regulates temperature, prevents water loss, and aids in vitamin D synthesis.
- Skeletal system: provides structure, support, movement, produces blood cells, stores minerals and fats.
- Muscular system: facilitates movement, maintains posture, generates heat.
- Lymphatic system: removes foreign substances, combats disease, maintains tissue fluid balance, absorbs dietary fats.
- Respiratory system: exchanges gases (oxygen and carbon dioxide) and regulates blood pH.
- Digestive system: carries out digestion, nutrient absorption, and waste elimination.
- Nervous system: detects sensations, controls movements, and manages physiological processes.
- Endocrine system: influences metabolism, growth, and reproduction through hormones.
- Circulatory system: transports nutrients, waste, gases, and hormones; plays a role in immune response and temperature regulation.
- Urinary system: removes waste, regulates blood pH, ion, and water balance.
- Reproductive system: produces oocytes/sperm, facilitates fertilization and fetal development, and governs sexual function.
