Study Notes
Autoregulation and Extrinsic Regulation
- Autoregulation occurs when cells experience low oxygen, causing them to release chemicals that dilate blood vessels.
- Extrinsic regulation involves the nervous system, which increases heart rate during exercise to enhance blood circulation.
Essential Life Processes
- Organization: Living organisms exhibit a high degree of organization at both cell and tissue levels.
- Metabolism: Comprises all chemical processes occurring within the body, crucial for energy production and maintenance of cellular functions.
- Responsiveness: The ability of the body to detect and react to internal or external environmental changes.
- Reproduction: Involves cell division for growth, repair, replacement, or the formation of new individuals.
- Movement: Refers to motion within the body, encompassing internal actions like blood flow and cellular processes.
- Differentiation: Developmental process where unspecialized cells become specialized cells.
- Growth: Increase in body size resulting from an increase in the number or size of cells.
Introduction to Human Anatomy and Physiology
- Human Anatomy: Focuses on the study of normal structures of the body and the relationships among these structures.
- Human Physiology: Studies how these structures function and processes that support the body's functioning.
Divisions of Human Anatomy
- Gross/Macroscopic Anatomy: Involves the examination of structures visible to the naked eye.
- Systemic Anatomy: Studies normal structures of distinct body systems.
- Regional Anatomy: Focuses on studying structures based on specific body regions.
- Surface Anatomy: Examines external features and their relation to deeper anatomical structures.
Structural Organization of the Body
- Chemical Level: Pertains to atoms and molecules, the basic building blocks of life.
- Cellular Level: Comprises cells, the fundamental units of life.
- Tissue Level: Involves groups of similar cells performing a specific function.
- Organ Level: Refers to structures composed of two or more types of tissues working together.
- System Level: Comprises multiple organs that perform a common function.
