Organ Systems of the Human Body Ms Clark PVMHS
Integumentary System Components: Functions: Skin and structures derived from it (hair, nails, sweat and oil glands) Functions: Forms the external body covering Protects the body Eliminates some wastes Helps make vitamin D Detects sensations such as pressure, pain, heat, and cold.
Integumentary System
Skeletal System Components: Functions: Bones, joints, cartilages Protects and supports body organs Provides framework that muscles use to cause movement Blood cells are formed within bones Stores minerals
Skeletal System
Muscular System Components: Functions Skeletal muscle tissue – muscle usually attached to bones Functions Movement Maintaining posture Producing heat
Muscular System
Nervous System Components: Functions: Brain, spinal cord, nerves, and sense organs such as eyes and ears Functions: Regulates body activities through nerve impulses by detecting changes in the environment Responds to changes by activating appropriate muscles and glands
Nervous System
Endocrine System Components: Functions: All glands and tissues that produce hormones (chemical regulators of body functions) Functions: Secrete hormones that regulate processes such as growth, reproduction, and metabolism.
Endocrine System
Cardiovascular/Circulatory System Components: Heart, blood, blood vessels Functions: Transport blood throughout body Blood carries oxygen and nutrients to cells Blood carries carbon dioxide and wastes away from cells
Cardiovascular/Circulatory System
Immune/Lymphatic System Components: Lymphatic fluid and vessels; spleen, thymus, lymph nodes, tonsils Functions: Picks up fluid leaked from blood vessels and returns it to blood Protects body against disease-causing organisms
Immune/Lymphatic System
Respiratory System Components: Functions: Lungs, pharynx (throat), larynx (voice box), trachea (windpipe), bronchus Functions: Keeps blood supplied with oxygen Removes carbon dioxide
Respiratory System
Digestive System Components: Functions: Mouth, esophagus, stomach, small and large intestines, rectum, anus Functions: Breaks down food so that it can be absorbed into blood and distributed to cells Eliminates solid wastes
Digestive System
Urinary/Excretory System Components: Kidney, ureter, urinary bladder, urethra Functions Eliminates nitrogenous wastes from the body Regulates volume and chemical composition of the blood Maintains body’s mineral balance Helps regulate red blood cell production
Urinary/Excretory System
Reproductive System Components: Functions: Female: Ovaries, uterine tube, uterus, vagina, mammary glands Male: Testes, penis, vas deferens, prostate gland, seminal vesicles Functions: Production of offspring Provides for conception and childbearing
