Major structures: Bones; joints; and cartilage.
Major functions: supports and shapes the body; protects the internal organs; forms some blood cells and stores minerals.
Major structures: Muscles; fascia; and tendons.
Major functions: holds the body erect; makes movement possible; moves body fluids and generates body heat.
Major structures: Heart; arteries; veins; capillaries; and blood.
Major functions: Blood circulates throughout the body to transport oxygen and nutrients to cells and to carry waste products to the kidneys where waste is removed to filtration.
Major structures: Lymph; lymphatic vessels; and lymph nodes.
Major functions: Removes and transports waste products from the fluid between the cells; destroys harmful substances such as pathogens and cancer cells in the lymph nodes; returns the filtered lymph to the bloodstream where it becomes plasma again.
Major structures: Tonsils, spleen, thymus, skin, and specialized blood cells.
Major functions: Defends the body against invading pathogens and allergens.
Major structures: Nose; pharynx; trachea; larynx; and lungs.
Major functions: Brings oxygen into the body for transportation to the cells; removes carbon dioxide and some water waste from the body.
Major structures: Mouth; esophagus; stomach; small intestines; large intestines; liver; and pancreas.
Major functions: Digests ingested food so it can be absorbed into the bloodstream; eliminates solid waste.
Major structures: Kidneys; ureters; urinary bladder; and urethra.
Major functions: Filters blood to remove waste; maintains the electrolyte and fluid balance within the body.
Major structures: Nerves; brain; and spinal cord.
Major functions: Coordinates the reception of stimuli; transmits messages throughout the body.
Major structures: Eyes and ears.
Major functions: Receive visual and auditory information and transmit it to the brain.
Major structures: Skin, sebaceous glands; and sweat glands.
Major functions: Protects the body against invasion by bacteria; aids in regulating the body temperature and water content.
Major structures: Adrenal glands; gonads; pancreas; parathyroids; pineal; pituitary; thymus; and thyroid.
Major functions: Integrates all body functions.
Major structures: Male- penis and testicles; Female- ovaries, uterus, and vagina.
Major functions: Produces new life.
Two major: Dorsal and ventral; are spaces within the body that contain and protect internal organs.
Located along the back of the body and head; contains organs of the nervous system that coordinate body functions and is divided into two portions: Cranial and spinal cavity.
Located within the skull; surrounds and protects the brain.
Located within the spinal column; surrounds and protects the spinal cord.
Located along the front of the body; contains the body organs that maintain homeostasis.
The process through which the body maintains a constant internal environment.

A muscle that separates the thoracic and abdominal cavities.
Contains primarily the major organs of digestion; referred to as abdomen.
Space formed by the hip bones and it contains primarily the organs of the reproductive and excretory systems.

The defective development, or the congenital absence of an organ or tissue.
Incomplete development of an organ or tissue usually due to a deficiency in the number of cells.
Change in the structure of cells and in their orientation to each other; characteristic of tumor formation in cancers.
