 * The pharynx is a portion of the digestive tract between the mouth and the esophagus that serves as a passageway for food and also for air on its way to the trachea.
 * The esophagus is the muscular tube for moving swallowed food from the pharynx to the stomach.
 * The stomach is the muscular sac that mixes food with gastric juices to form chyme, which enters the small intestine.
 * The small intestine is a long, tubelike chamber of the digestive tract between the stomach and the large intestine.
 * The large intestine is the last major portion of the digestive system tract, extending from the small intestine to the anus and consisting of the rectum, the colon, the rectum and the anal canal.
 * The appendix is in humans. It also is small, tubular appendage than extends outward from the cecum of the large intestine.
 * The rectum i sTerminal end of the digestive tube between the sigmoid colon and the anus.
 * The pancreas is the internal organ that produces digestive enzymes and the hormones insulin and glucagon.

 * The kidney is the organ in the urinary system that produces and excretes urine.
 * The ureter is one of two tubes that takes urine from teh kidneys to the urinary bladder.
 * This organ collects urine excreted by the kidneys. In males the bladder is superior to the prostate, and in females the bladder is seperate from teh rectum by the rectouterine excavation ad it is separated from the uterus by the vesicouterine excavation. The bladder is hallow, muscular.
 * The urethra is a tubular structure that receives urine from the bladder and carries it to th outside of the body.
 * The larunx is the cartilaginous organ located between the pharynx and teh trachea that contains the vocal cords and also called the voice box.
 * The trachea is the passageway that conveys air from the larynx to the bronchi, and is also called the windpipe.
 * One of the two major divisions of the trachea leading to the lung.
 * The smaller air passages in the lungs that begin at the bronchi and terminate in alveoli.
 * Tiny, tubes at the end of the airways that fill the lungs.
 * The pituitary gland is the endocrine gland that lies just inferior to the hypothalamus: it also consists of the enterior pituitary and posterior pituitary.
 * The adrenal Gland is an endocrine gland that lies atop a kidney consisting of the inner adrenal medulla and the outer adrenal cortex.
