| Organ Systems & Components | Functions |
|---|---|
| INTEGUMENTARY SYSTEM Skin and associated structures: hair, nails, sweat and oil glands | Regulate body temperature; Protection; Vitamin D synthesis; Detects sensations |
| SKELETAL SYSTEM All bones and associated cartilage | Supports and protects; Assists with movements; Blood production; Mineral storage |
| MUSCULAR SYSTEM Skeletal muscles and other muscle tissue (cardiac and smooth) | Movement; Maintain posture; Heat production |
| NERVOUS SYSTEM Brain, spinal cord, nerves, sense organs, e.g. eye and ear. | Regulate body activities: sensory info to the brain and motor signals out to body |
| ENDOCRINE SYSTEM Glands and tissues that produce hormones, e.g., pituitary, thyroid, other organs with endocrine function | Hormones regulate body activities of target organs |
| CARDIOVASCULAR SYSTEM Blood (plasma and cells), heart, arteries, veins, capillaries | Carrying substance through body, e.g., hormones, waste, gases, nutrients; Regulates temperatures; Fights disease (white blood cells) |
| LYMPHATIC AND IMMUNE SYSTEMS Lymph: lymph fluid, vessels and structures (spleen, lymph nodes) Immune: White blood cells of immune response (B cells and T cells) | Lymph: Return protein and fluid to blood. Immune: Cells protect against disease-causing agents |
| DIGESTIVE SYSTEM Mouth, esophagus, stomach, small & large intestines, rectum, anus, and accessory organs: salivary glands, liver, pancreas, etc. | Mechanical and chemical breakdown of food; Absorption of nutrients; Elimination of solid waste. |
| URINARY SYSTEM Kidneys, ureters, bladder, urethra | Produce & eliminate urine; Regulate volume and chemical composition of blood; Helps regulate red blood cell production |
| REPRODUCTIVE SYSTEM Gonads and associated organs---Female: ovaries, uterine tubes, uterus, vagina---Male: testicles, epididymis, vas deferens, penis | Gamete production; Hormone production; Development of embryo |
| RESPIRATORY SYSTEM Lungs and air passages, e.g., trachea. | Gas exchange; Blood pH regulation; Sound production in larynx |
