Body Systems
Nervous System
Controls and coordinates functions throughout the body by responding to external and internal stimuli. brain, spinal cord, nerves
Immune System
Defends our bodies from harmful pathogens and foreign toxins.
Digestive System
Physically and chemically breaks down food molecules into very small molecules and absorbs these into our bloodstream; expels waste.
Muscular
Protects organs; supports breathing (diaphragm); cardiac muscle pumps blood; smooth muscle is found in the digestive system, circulatory system, excretory and reproductive system to help facilitate body functions; skeletal muscle provides movement. (muscles)
Integumentary System
Protects tissues and organs, protects against infection; helps maintain temperature; stores water and fat; serves as a receptor for pressure, touch, pain, and heat
Skeletal System
Protects vital organs; supports your body; works with your muscular system to create movement; stores minerals such as calcium; produces blood cells. (bones)
Respiratory System
Supplies oxygen to our cells from the atmosphere and removes carbon dioxide.
organs of reproductive system
organs: Male: testes, scrotum, penis Female: ovaries, fallopian tubes, uterus, vagina
organs of the immune system
organs: bone marrow, thymus gland, spleen, lymph nodes, tonsils, appendix
organs of skeletal system
organs: bones, ligaments, cartilages
organs of the nervous system
organs: brain, spinal cord, nerves
Organs of the Circulatory System
organs: heart, arteries, veins, capillaries
organs of the endocrine system
organs: hypothalamus, pituitary, thyroid, parathyroid, adrenals, pancreas, ovaries, testes (hormones)
organs of excretory system
organs: kidneys, ureters, bladder, urethra
Organs of the digestive system
organs: mouth, esophagus, stomach, small intestine, large intestine
organs of the respiratory system
organs: nose, pharynx, larynx, trachea, bronchi, lungs, alveoli
organs of the muscular system
organs: skeletal muscles, smooth muscles, and cardiac muscles
Organs of the Integumentary System
organs: skin, hair, nails, sweat glands, sebaceous glands
Reproductive System
.To produce sex cells and transport them so that fertilization may occur; to produce hormones that regulate the production of sex cells and offspring
Endocrine System
Communicates brain and body with chemical messengers called hormones; we need the endocrine system to grow, reproduce, and maintain homeostasis.
Excretory System
Filters and removes excess waste from the bloodstream through the kidneys.
Circulatory System
Works closely with other body systems to help transport materials throughout the body such as oxygen, hormones, nutrients, waste, lymph, and immune cells.
