WHAT ARE THE (TEN) SYSTEMS OF THE BODY?
1:Muscular system- skeletal muscle- voluntary, visceral muscle- lining of hollow internal organs-involuntary, cardiac muscle- involuntaryFunctions- allows movement (locomotion and digestion); maintains posture and produces heat. 2-Urinary system- 2 kidneys, 2 ureters, 1 bladder, 1 urethraFunctions- regulates chemical composition of blood; eliminates waste; regulates fluid and electrolyte balance and volume; maintains acid-base balance of body. 3-Respiratory system- 2 lungs, nose, mouth, pharynx, larynx, trachea, and bronchial tree (passageway from lungs to outside atmosphere)Functions- supplies oxygen to blood- cells; eliminates (Carbon Dioxide); regulates acid-base balance of blood. 4-Digestive system- includes salivary glands, liver, gallbladder, and pancreas, as well as the alimentary canal- tube from mouth to anus- mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus. Functions- prepares food for absorption and eliminates solid waste 5-Endocrine system- testis/ovaries, pancreas, adrenal, thymus, thyroid, parathyroids, pineal & pituitary glands, and temporarily placenta; ductless glands.Functions- regulates body activities through hormones released into blood stream and carried by cardiovascular system. 6-Reproductive system- male/female organsFunctions- produce, transport, and store germ cells and ultimately reproduce human organism 7) Skeletal system- framework of the body. Composed of 206 bones and their associated cartilage.Functions- support and protect body; allows movement along with muscles, produces blood cells; stores calcium. **Osteology- study of bones **Arthrology- study of joints 8) Integumentary system- skin, hair, nails, sweat and oil glands.Functions- regulates body temperature; protects body; eliminates waste; receives stimuli such as temperature, pressure, pain. 9)Nervous system- brain, spinal cord, nerves, ganglia, eyes, earsFunctions- regulates body activity with electrical impulses 10)Circulatory system- composed of blood; heart; blood vessels; lymph glands; spleen.Functions- distributes oxygen to cells; transports wastes from cells including water, electrolytes, hormones, and enzymes; protects against disease. Prevents hemorrhage by forming blood clots; helps regulate body temperature.
