Study Notes
Introduction to Anatomy and Physiology
- Anatomy: Study of the structure of body parts and their relationships.
- Physiology: Study of the function of body parts and how they work together.
Levels of Organization
- Chemical Level: Atoms and molecules (e.g., DNA, proteins).
- Cellular Level: Cells, the basic unit of life (e.g., muscle cells, nerve cells).
- Tissue Level: Groups of similar cells performing a specific function (e.g., epithelial, connective, muscle, nervous).
- Organ Level: Structures made up of two or more different types of tissues (e.g., heart, lungs).
- Organ System Level: Groups of organs that work together (e.g., respiratory system, digestive system).
- Organism Level: The complete living entity that can function independently.
Body Systems
- Integumentary System: Protects body, regulates temperature (e.g., skin, hair, nails).
- Skeletal System: Supports body, protects organs, facilitates movement (e.g., bones, cartilage).
- Muscular System: Enables movement, maintains posture (e.g., skeletal muscles).
- Nervous System: Responds to internal and external changes (e.g., brain, spinal cord).
- Endocrine System: Secretes hormones for regulation (e.g., glands, pancreas).
- Cardiovascular System: Transports nutrients and oxygen (e.g., heart, blood vessels).
- Lymphatic System: Maintains fluid balance, immune response (e.g., lymph nodes, spleen).
- Respiratory System: Supplies oxygen, removes carbon dioxide (e.g., lungs, trachea).
- Digestive System: Breaks down food for energy (e.g., stomach, intestines).
- Urinary System: Eliminates waste, regulates fluids (e.g., kidneys, bladder).
- Reproductive System: Produces offspring (e.g., ovaries, testes).
Homeostasis
- Definition: The body’s ability to maintain stable internal conditions despite external changes.
- Key processes: Feedback mechanisms, including:
- Negative Feedback: Restores balance (e.g., regulating body temperature).
- Positive Feedback: Enhances change (e.g., blood clotting).
Basic Cell Structure
- Cell Membrane: Semi-permeable barrier; controls entry/exit.
- Cytoplasm: Fluid inside the cell where organelles are located.
- Nucleus: Contains genetic material (DNA); controls cell functions.
- Organelles: Specialized structures (e.g., mitochondria for energy, ribosomes for protein synthesis).
Tissue Types
- Epithelial Tissue: Covers body surfaces, and lines cavities (e.g., skin epithelium).
- Connective Tissue: Supports, binds other tissues (e.g., bone, blood).
- Muscle Tissue: Facilitates movement (e.g., skeletal, cardiac, smooth).
- Nervous Tissue: Transmits impulses (e.g., neurons, glial cells).
Important Physiological Concepts
- Metabolism: All chemical reactions in the body (catabolism and anabolism).
- Homeostasis Maintenance Mechanisms: Sensors, control center, effector responses.
- Tissue Repair Mechanisms: Inflammatory response, regeneration, fibrosis.
Overview of Organ Functions
- Heart: Pumps blood throughout the body.
- Lungs: Facilitate gas exchange (O2/CO2).
- Kidneys: Filter blood, create urine.
- Liver: Metabolizes nutrients, detoxifies toxins.
Conclusion
- Anatomy and physiology are interrelated fields essential for understanding how the human body functions and maintains health. Understanding these concepts provides a foundation for more advanced studies in medical and biological sciences.
