Study Notes

Ventral Body Cavity

Divided into thoracic and abdominopelvic cavities by the diaphragm.
Each thoracic cavity contains a lung, surrounded by pleural cavities.
Mediastinum houses the trachea, esophagus, thymus, and major vessels.

Thoracic Cavity

Comprises right and left pleural cavities surrounding respective lungs.
Contains the pericardial cavity which surrounds the heart.

Abdominopelvic Cavity

Divided into abdominal and pelvic cavities.
Abdominal cavity contains digestive organs and glands.
Pelvic cavity houses the urinary bladder, reproductive organs, and the last portion of the digestive tract.

Protection and Structure

Ventral body cavity protects internal organs and allows for organ movement.
Linings prevent friction between organ movements.

Serous Membranes

Thin, strong membranes lining cavities not open to the outside.
Produce fluid transudate to reduce friction.
Comprised of a parietal layer (covers cavity) and a visceral layer (covers organs).

Specific Serous Membranes

Pleura: Lines and covers lungs within pleural cavities.
Peritoneum: Lines the abdominal cavity and covers abdominal organs.
Pericardium: Lines the pericardial cavity and covers the heart.

Retroperitoneal Space

Area behind peritoneum, in front of the muscular body wall.
Contains pancreas, kidneys, ureters, adrenal glands, and parts of the digestive tract.

Cutaneous and Synovial Membranes

Cutaneous Membrane: Skin; thick, waterproof, and dry.
Synovial Membranes: Line moving joints, produce synovial fluid for lubrication.

Anatomical Terminology

Unilateral/Ipsilateral: Pertaining to one side.
Bilateral: Pertaining to both sides.
Contralateral: On opposite sides.

Position and Directional Terms

Flexion/Extension: Bending/straightening joints.
Abduction/Adduction: Movement away/toward the midline.
Pronation/Supination: Turning arm/foot downward/upward.

Terms of Movement

Retraction/Protraction: Movement backward/forward.
Elevation/Depression: Raising/lowering parts.
Rotation/Circumduction: Turning around an axis/circular motion.

Body Regions

Divided into four quadrants: Right Upper Quadrant (RUQ), Left Upper Quadrant (LUQ), Right Lower Quadrant (RLQ), and Left Lower Quadrant (LLQ).

Characteristics of the Human Body

Organization increases complexity in structure and function.
Metabolism includes all chemical reactions in the body.

Body Systems Overview

Each system serves distinct functions and consists of major organs:

Cardiovascular System

Composed of the heart, blood, and blood vessels.
Distributes materials and assists in temperature control.

Lymphatic System

Includes spleen, thymus, lymphatic vessels, lymph nodes, and tonsils.
Defends against infection and returns tissue fluids to the bloodstream.

Respiratory System

Major organs include nasal cavities, lungs, and trachea.
Facilitates gas exchange and sound production.

Digestive System

Comprises organs like the stomach, intestines, and liver.
Processes food, absorbs nutrients, and stores energy.

Urinary System

Consists of kidneys, ureters, urinary bladder, and urethra.
Excretes waste, regulates water balance, and stores urine.
