Study Notes
Major Body Systems
- The human body is a complex network of systems working together.
- Body systems include skeletal, muscular, nervous, circulatory, respiratory, digestive, endocrine, immune, integumentary, and reproductive.
Skeletal System
- Provides structure and support.
- Composed of bones, cartilage, and ligaments.
- Functions include protecting organs, producing blood cells, and storing minerals.
Muscular System
- Enables movement.
- Consists of skeletal, smooth, and cardiac muscles.
- Functions involve motion, posture maintenance, and heat production.
Nervous System
- Controls and coordinates bodily functions.
- Composed of the brain, spinal cord, and nerves.
- Functions encompass sensory input, processing, and motor output.
Circulatory System
- Transports blood, nutrients, and oxygen.
- Includes the heart, blood vessels, and blood.
- Functions include nutrient distribution, waste removal, and immune response.
Respiratory System
- Facilitates gas exchange.
- Includes lungs, trachea, and diaphragm.
- Functions involve oxygen intake and carbon dioxide release.
Digestive System
- Breaks down food for nutrient absorption.
- Composed of the mouth, esophagus, stomach, intestines, and associated glands.
- Functions encompass digestion, nutrient absorption, and waste elimination.
Endocrine System
- Regulates body functions using hormones.
- Consists of glands like the pituitary, thyroid, and adrenal glands.
- Functions control homeostasis, growth, and metabolism.
Immune System
- Defends against illnesses and pathogens.
- Includes white blood cells, lymph nodes, and spleen.
- Functions involve fighting infections and eliminating pathogens.
Integumentary System
- Protects the body from external harm.
- Comprises skin, hair, and nails.
- Functions include protection, sensation, and temperature regulation.
Reproductive System
- Enables the production of offspring.
- Involves male and female reproductive organs.
- Functions encompass gamete creation, sexual function, and hormone regulation.
