Study Notes

Pathophysiology and Disease Aging

Involves functional changes that occur with disease processes and aging.

Levels of Structural Organization and Body Systems

The human body has multiple organ systems that function together.

Introduction to Different Body Systems

Integumentary System

Components: Skin, hair, fingernails, toenails, sweat glands, oil glands.
Functions:
- Protects the body.
- Regulates body temperature.
- Eliminates wastes.
- Synthesizes vitamin D.
- Detects sensations.
- Stores fat.
- Provides insulation.

Musculoskeletal System

Components: Bones, joints, cartilages.
Functions:
- Supports and protects the body.
- Provides surfaces for muscle attachment and facilitates body movements.
- Houses cells that produce blood cells.
- Stores minerals and lipids.

Muscular System

Components: Skeletal muscle tissue, smooth muscle tissue, cardiac muscle tissue.
Functions:
- Enables body movements.
- Maintains posture.
- Generates heat.

Nervous System

Components: Brain, spinal cord, nerves, special sense organs (eyes and ears).
Functions:
- Generates action potentials.
- Detects changes in internal and external environments.
- Interprets sensory changes.
- Site of maturation and proliferation of T and B cells for immune defense.

Respiratory System

Components: Lungs, air passageways (pharynx, larynx, trachea, bronchial tubes).
Functions:
- Transfers oxygen and carbon dioxide.
- Regulates acid-base balance.
- Produces sound.

Digestive System

Components: Mouth, pharynx, esophagus, stomach, small intestine, large intestine, anus, accessory organs (salivary glands, liver, gallbladder, pancreas).
Functions:
- Achieves physical and chemical breakdown of food.
- Absorbs nutrients.
- Eliminates solid waste.

Urinary System

Components: Kidneys, ureters, urinary bladder, urethra.
Functions:
- Produces, stores, and eliminates urine.
- Eliminates wastes and regulates blood volume/chemical composition.
- Maintains acid-base balance.
- Balances minerals.
- Regulates red blood cell production.

Body Cavities and Membranes

Thoracic and Abdominal Cavity Membranes

Pleura
- Visceral pleura: Adheres to lung surface.
- Parietal pleura: Lines chest wall.
Pericardium
- Visceral pericardium: Covers heart's surface.
- Parietal pericardium: Lines cavity walls.
Peritoneum
- Visceral peritoneum: Covers abdominal organs.
- Parietal peritoneum: Lines abdominal wall, covering diaphragm's inferior surface.
