ORGANS SYSTEMS REVIEW
The human body is made up of several organ systems that work together as one unit.
The ten major organ systems of the body are listed below, along with several organs that are associated with each system.
Circulatory:
Cardiovascular: heart and blood
Lymphatic: Lymph nodes and vessels, thymus, spleen
Digestive:
Primary organs: mouth, stomach, intestines, rectum
Accessory organs: teeth, tongue, liver, pancreas
Endocrine:
pituitary gland, pineal gland, ovaries, testes, thyroid gland
Integumentary:
nails, hair, skin, sweat glands
Muscular:
muscles
Nervous:
brain, spinal cord, nerves
Reproductive:
Male: testes, scrotum, penis, vas deferens, prostate
Female: ovaries, uterus, vagina, mammary glands
Respiratory:
lungs, nose, trachea, bronchi
Skeletal:
bones and joints
Urinary/Excretory:
kidneys, urinary bladder, urethra, ureters
It is important to keep in mind that these systems don't just exist as individual units. The final product of these cooperating systems is one unit
called the body. Each system depends on the others, either directly or indirectly, to keep the body functioning normally
