Body Organ Systems
Term | Definition |
---|---|
Circulatory System | Transport oxygen, nutrients and other needed materials to cells; transports wastes away from cells (Heart, blood vessels, |
Immune Systems | Protects against diseases(lymph nodes, lymph vessels, white blood cells) |
Connective Tissue | A body tissue that provides support for the body and connects all of its part( ligaments, tendons, blood, fat cartilage) |
Epithelial Tissue | A body tissue that covers the surfaces of the body, inside and out(skin, lining of organs) |
Reproductive System | Produces sex cells; produces offspring( testes, sperm, ovaries, eggs, gametes) |
Organism | Any living thing. All systems working together( Human, dog, bird) |
Skeletal System | Moves and supports the body; protects internal organs; makes blood; stores material( bones, cartilage, ligaments) |
Muscular System | Moves the body; moves material through the body( skeletal muscles, tendons, smooth muscles, cardiac muscles) |
Lymphatic system | Helps fight diseases; extension of immune and circulatory systems( lymph nodes, lymph vessels, lymph) |
Nervous Tissue | A body tissue that carries electrical messages back and forth between the brain and every other body part of the body(brain and spinal cord) |
Excretory System | Removes wastes including excess water, unusable materials from food, carbon dioxide, and harmful materials(skin, lungs, kidneys, bladder, ureters, urethra |
Organ System | Two or more organs working together to perform a similar function( muscular system, skeletal system, cardiovascular system) |
Tissue | a group of similar cells that perform the same function( epithelial, connective, muscle, nervous) |
Organ | Two or more tissues that work together to perform a similar function(stomach, heart, intestines) |
Digestive system | Breaks down food into nutrients cells can use; disposes of solid wastes( mouth, esophagus, stomach, small intestines, large intestines, liver, pancreas, gall bladder, rectum, anus) |
Muscle Tissue | A body tissue that contracts or shortens, making body parts move( cardiac, smooth, skeletal) |
Respiratory system | Exchanges oxygen and carbon dioxide between the body and the external environment( nose, pharynx, larynx, trachea, bronchi, lungs) |
Nervous system | Detects and responds to changes in the environment; transmits information throughout the body( brain, spinal chord, nerves) |
Endocrine System | Secretes hormones to regulate body functions; coordinates other organ systems; helps maintain balance in body systems( pituitary gland, hypothalamus, thymus, thyroid, adrenals, pancreas, testes, ovaries) |
Integumentary System | Separates the body and the external environment; eiliminates waste( skin, hair, nails) |
