Document Summary
Small things shouldn"t be leaving so we need to bring them back in. Balance and match daily intake with the daily loss. Kidneys make adjustments for our diet, environment, activityetc (are we in taking enough water) Kidney: cortex (outer area) vs. medulla (middle area) Renal pelvis: collects urine from all individual nephrons. Bladder: parasympathetic: activivate and get bladder to squeeze. Urethra: urine passing through from bladder to outside body. Internal urethral sphincter: sympathetic (close is no movement, open it we can move) not skeletal. External urethral sphincter: somatic (pass urine in socially acceptable places; control) skeletal muscle. Sphincters are kept closed therefore there is no exit process. Sphincters are closed, and bladder fills. (like bath tub filling up, bladder expands, compressed down when empty. Increase in n we will increase the pressure within the bladder) Activate mechanoreceptors (stretch) to tell the body to let the urine out. Bladder contracts: decrease the volume, increase the pressure.
