Organ systems Part II
This is the second part of the organs systems review. Keep in mind that this review is for massage therapy students who wish to accelerate their learning. It covers circulatory, lymphatic, urinary and reproductive systems of the body.
The Circulatory system - The circulatory system is made of the heart, arteries, veins and capaillaries. The muscular pumping device is called the heart. The cirulatory system is a closed system of vessels. The primary function of the cardiovasculary system is transportation. The bloodstream helps regulate body temperature, involved with immunity and carries oxygen, carbon dioxide, nutrients and hormones.
The Lymphatic system - The lymphatic system is composed of lymph nodes, lymphatic vessels, tonsils, thymus and spleen. The thymus functions as an organ for both the lymphatic system and the endocrine system. Lymph is a whitish, watery fluid that contains lymphocyctes, proteins, and fatty molecules. Lymph does not contain any red blood cells. The areas of the body with many lymph nodes are the armpit or axillary area, the groin, and inguinal.
The respiratory system - The resporatory system is composed of the nose, pharynx, larynx, trachea, bronchi and lungs. The tiny, thin-walled sacs of the lungs are called alveoli and look similar to small grapes under a microscope. Carbon dioxide is eliminated from the body via the lungs of the respiratory system.
The Digestive system - The digestive system uses another word for chewing and it is masstication. The flap that seperates the esophagus and the trachea is called the epiglotis. The appendix looks like a little pinky finger hanging off the large intestine. Inflamation of the appendix is called appendicitis. The gastroinestinal tract(GI) is comprised of the primary organs which include the mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum, and anal canal. The GI tract is a tube created by the primary organs taht is open at both ends. Feces is eliminated from the anus
The Urinary system - The urinary system includes the kidneys, ureters, bladder and urethra. The kidneys play an important role in maintaining the electrolyte, water and acid-base balances of the body. The waste that the kidneys produce is called urine. The order of he body parts that allow waste flow from the kidneys is the ureters, bladder, and finally the urethra. In men, the urethra or penis is part of the urinary and reproductive system. Water and salts are eliminated by the kidneys of the urinary system.
The reproductive system - The female gonads of the reproductive system are also called the ovaries. The male gonads are called testes.
