Study Notes
Anatomy vs. Physiology
- Anatomy studies the body's physical structures, including organs, tissues, and cells.
- Physiology examines the functions and processes that allow the body to operate effectively.
Levels of Structural Organization
- Chemical Level: Comprises all atoms and molecules forming the basis of body structure.
- Cellular Level: Represents the arrangement of atoms and molecules into cells, the basic units of life.
- Tissue Level: Involves groups of similar cells working together to perform specific functions.
- Organ Level: Formed by the combination of different tissues to create organs with distinct roles.
- Organ System Level: Multiple organs collaborate to achieve a common purpose within the body.
- Organism Level: All organ systems integrate to function as a complete living entity.
Examples of Structural Organization
- Chemical Level: Includes atoms such as carbon and molecules like proteins.
- Cellular Level: Comprises individual cells that perform various functions.
- Tissue Level: Encompasses epithelial, muscle, and connective tissues as fundamental categories.
- Organ Level: Includes key organs such as the heart, lungs, and brain.
- Organ System Level: Examples are the circulatory system and nervous system, each serving distinct functions.
- Organism Level: Represents a fully developed human being comprised of all integrated systems.
Eleven Organ Systems and Their Functions
- Integumentary System: Protects internal structures and regulates temperature.
- Skeletal System: Provides structural support and protection for vital organs.
- Muscular System: Facilitates movement and stabilizes body posture.
- Nervous System: Monitors and responds to changes in the environment, coordinating body functions.
- Endocrine System: Regulates long-term physiological activities through hormone secretion.
- Lymphatic System: Defends against pathogens and helps maintain fluid balance.
- Cardiovascular System: Essential for oxygen and nutrient transportation throughout the body.
- Respiratory System: Responsible for the intake of oxygen and removal of carbon dioxide via gas exchange.
- Digestive System: Breaks down food and absorbs nutrients into the bloodstream.
- Urinary System: Manages fluid balance and waste removal to maintain homeostasis.
- Reproductive System: Produces, stores, and transports gametes for reproduction.
