Study Notes
Organ Systems Overview
- Organ systems include Integumentary, Nervous, Muscular, Cardiovascular, Respiratory, Lymphatic and Immunity, Skeletal, Urinary, Digestive, Endocrine, and Reproductive.
- Each system has specific functions crucial for maintaining body homeostasis.
Integumentary System
- Comprises hair, skin, nails, and associated glands (sweat and oil).
- Protects body, regulates temperature, eliminates waste, helps synthesize vitamin D, and stores fat.
Skeletal System
- Consists of bones, cartilage, and joints.
- Supports and protects body, facilitates muscle attachment, aids movement, produces blood cells, and stores minerals/lipids.
Muscular System
- Mainly skeletal muscle.
- Responsible for body movements, maintaining posture, and heat production.
Nervous System
- Includes the brain, spinal cord, and nerves.
- Generates electrical impulses to regulate activities, detect sensations, and interpret internal/external changes.
Endocrine System
- Composed of glands such as the pineal, hypothalamus, pituitary, thyroid, and gonads.
- Regulates body functions by releasing hormones, chemical messengers transported through blood.
Cardiovascular System
- Consists of the heart, blood vessels (arteries and veins), and blood.
- Pumps blood to transport oxygen/nutrients to cells and removes carbon dioxide/waste; supports immune function.
Lymphatic System and Immunity
- Comprises lymphatic vessels, lymph nodes, thymus, and spleen.
- Returns proteins and fluids to blood, handles lipids from the GI tract, and supports B and T cell maturation for immune defense.
Respiratory System
- Contains trachea, lungs, nasal cavity, and other air passageways.
- Exchanges oxygen and carbon dioxide, aids in acid-base balance, and plays a role in phonation.
Digestive System
- Includes organs like the esophagus, stomach, liver, pancreas, and intestines.
- Breaks down food physically and chemically, absorbs nutrients, and eliminates solid waste.
Urinary System
- Comprises kidneys, ureters, urinary bladder, and urethra.
- Produces and eliminates urine, regulates blood volume and chemical composition, and maintains acid-base balance.
Reproductive System
- Male: Testes, prostate, seminal vesicles; produces sperm and associated hormones.
- Female: Ovaries, uterus, mammary glands; produces oocytes and hormones that regulate reproduction.
Basic Life Processes
- Include metabolism (both anabolism and catabolism), growth, reproduction, differentiation, movement, and responsiveness.
Homeostasis
- Refers to maintaining a stable internal environment despite external changes.
- Achieved through feedback mechanisms (negative and positive) involving sensors, control centers, and effectors.
Medical Imaging
- Techniques such as X-ray, CT, MRI, ultrasound, and PET scans are used to visualize internal body structures for diagnosis.
- X-ray provides images of dense tissues; CT offers 3D views; MRI visualizes soft tissues; ultrasound is safe and non-invasive; PET scans assess metabolic activity.
Abdominopelvic Regions
- Divided into quadrants: Right/Left Upper Quadrant (RUQ/LUQ), Right/Left Lower Quadrant (RLQ/LLQ) for anatomical referencing.
- Regions also segmented into specific areas such as hypochondriac, lumbar, and iliac regions.
Key Takeaways
- Anatomy refers to structure, while physiology pertains to function.
- The human body consists of 11 organ systems and is organized into six levels of structural organization.
- Understanding organ systems and their functions is vital to grasping human biology and health.
