Study Notes
Overview of Human Anatomy and Physiology
- Studies the structure and function of the human body, involving intricate parts and coordinated functions.
- Complex checks and balances allow for detection and response to stimuli.
- Understanding anatomy and physiology is essential for health science careers and to evaluate medical treatments.
Importance of Anatomy
- Anatomy involves dissecting to study the body's structure.
- Provides foundational knowledge for understanding diseases and health discussions.
Homeostasis
- The body maintains balance among its parts through homeostasis.
- Example: Renzo experiences blood sugar fluctuations and uses insulin for regulation.
Chemical Level of Organization
- The characteristics of organisms are determined by their chemical makeup, involving interactions between atoms.
- Structure impacts function; for instance, collagen molecules provide skin strength but become fragile with age.
Cell Level
- Cells are the basic structural and functional units of organisms, containing organelles.
- Organelle functions include the nucleus for hereditary information and mitochondria for energy production (ATP).
Tissue Level
- Tissues consist of similar cells and surrounding materials, with four primary types: epithelial, connective, muscle, and nervous.
Organ Level
- Organs are composed of two or more tissue types performing common functions.
- Examples include the urinary bladder, skin, stomach, and heart.
Organ System Level
- Organ systems group organs based on shared functions.
- The urinary system includes the kidneys, ureters, bladder, and urethra, coordinating to produce and eliminate urine.
Major Organ Systems
- There are eleven major organ systems:
- Integumentary
- Skeletal
- Muscular
- Lymphatic
- Respiratory
- Digestive
- Nervous
- Endocrine
- Cardiovascular
- Urinary
- Reproductive
- Coordination among these systems is necessary for normal body function.
