Study Notes
Introduction to Physiology
- Physiology is the study of how living organisms and their parts function.
- Derived from Greek: "Physio" means nature and "Logy" refers to the study of.
- Pathophysiology links many diseases to physiological dysfunctions, highlighting its importance in medicine.
Levels of Organization
- Human body organization consists of cells, tissues, organs, and systems.
- Cells are the basic living units; differentiation occurs from a fertilized egg to specialized cells.
Tissue Types
- Four primary tissue types:
- Muscle Tissue: Generates mechanical force. Types include skeletal, smooth, and cardiac muscle.
- Nervous Tissue: Initiates and conducts electrical signals, facilitating communication between cells.
- Epithelial Tissue: Covers surfaces, lines passages, and forms glands; involved in protection, secretion, and absorption.
- Connective Tissue: Supports, connects, and anchors structures in the body, storing energy and filling spaces.
Organs and Systems
- Organs are formed from two or more types of tissues.
- Systems are groups of organs working together to perform complex functions.
Major Body Systems
- Integumentary System: Includes skin, hair, and nails; functions in protection and thermoregulation.
- Nervous System: Comprises the brain, spinal cord, and nerves; regulates other systems.
- Endocrine System: Consists of hormone-secreting glands; regulates body functions through hormones.
- Skeletal System: Includes bones and cartilages; provides movement and support.
- Muscular System: Made up of skeletal muscles; facilitates body movement.
- Circulatory System: Composed of the heart and blood vessels; circulates blood and lymph.
- Immune System: Includes bone marrow and lymphoid organs; protects against pathogens.
- Respiratory System: Encompasses lungs and airways; facilitates gas exchange.
- Urinary System: Contains kidneys and ducts; regulates blood volume and composition.
- Digestive System: Involves organs like the stomach and liver; breaks down food for nutrient absorption.
- Reproductive System: Comprises gonads and associated ducts; responsible for species continuation.
Key Concepts and Terms
- Tissue: Collection of specialized cells with similar function.
- Differentiation: Process where unspecialized cells become specialized.
- Muscle Force: Muscle tissue is specialized for generating mechanical force.
- Basic Living Unit: Cell is the fundamental unit of structure and function in the body.
Multiple Choice Questions (MCQs)
- Focus on understanding the definitions and functions of tissue types and organ systems for exam preparation. Answers reinforce the connection between structure and function in physiology.
