Excretory System By Corey Bryan and Bill the Gill • Kidney • Ureter • Urethra • Bladder • Renal Veins • Proximal Tubule • Waste • Collecting Duct • Urea • Homerostasis • Urine • Urine Formation • Nephron • Filtration • Glomerulus • Reabsorption • Bowman’s Capsule • Hypothalamus • Distal Tubule • ADH Many urinary system disorders include the following: • Infections • Kidney disease • Presence of kidney stones • Obstruction • Tumors • Kidney disease- A kidney transplant • Kidney Stones- require surgery or ultrasound • Tumors- Surgical resection, chemotherapy • Kidney Failure- dialysis, drug therapy, transplant • Infections- antibiotics • Collect water and filter body fluids. • Remove and concentrate waste products from body fluids and return other substances to body fluids as necessary for homeostasis • Eliminate excretory products from the body Kidney Dialysis is one way that technology effects the excretory system. The way it works is that a machine filters the blood for the person without the kidney. Another way is Kidney Transplants. When you need a kidney you will need a kidney transplant. After being filtered the clean blood gets sent in the renal vein. The kidneys filter the blood with microscopic filters called nephrons. Then water and dissolved materials go through reabsorption in the proximal and distal tubules. First the renal artery brings dirty blood to the kidneys. The wastes from the blood, which is now urine, goes into the renal pelvis, and that funnels into the ureters. The urine travels down the ureters into the bladder. Urine fills up the bladder and gets sent to the uretha The urine travels through the uretha to outside of the body. •The Nephron is the functional unit of the kidney •Blood flows into the kidney through the renal artery, which branches into capillaries associated with the glomerulus. Then Arterial pressure causes the water and solutes from the blood to filter into the capsule.
