Our bodies create sweat, carbon dioxide, stool and urine. Urine is produced by the kidneys and contains the hyproducts of metabolism. These includes salts, toxins and water which then end up in the blood. The kidneys filter and get rid of these waste substances from our blood. Without the kidneys, waste products would build up in the blood to levels which are dangerous. The kidneys regulate the important functions. An example of this is that the kidneys monitors and maintains the bodies balance and makes sure that our tissues receive enough water to function properly. The kidneys work together to perform the important functions. Besides filtering the blood, ...view middle of the document...
The hilum is the concave boarder of the kidney where the renal blood, lymph vessels, ureter. Hilum that transmits the vessels, nerves and ureter from the anterior and posterior. The renal renal vein exits, the renal artery enters and renal pelvis exits the kidney. The renal capsule is a fibrous layer which is around the kidney and is covered in a thick layer of perinephric adipose tissue. The function of the renal capsule is to provide protection from any damage. The renal capsule is linked to other layers. The medulla consists of tissue which are called renal pyramids. These renal pyramids which have spaced so the blood vessels pass. The medulla is composed of tiny tubes which are called the kidney tubules (class notes, 2015) and (Kidneys and urinary tract, 2015)
The nephrons help remove the excess water. Wastes and other substances from the blood. The nephrons also return substances such as sodium, phosphorus and potassium whenever they run low in the body. Each nephron has the glomerulus and renal tubule. The glomerulus is a tiny blood vessel which filters the blood. The tubules is a tiny tube where the wastes and extra fluid filter out f the glomerulus and pass through. Your kidneys then measure out the sodium and phosphorus release them back to the blood to return to the bodies (Kidneyhealthcare, no date). The nephrons consist of 3 parts such as the proximal convoluted tubule, medullary body and distal convoluted tubule. The renal artery enters the kidney. The artery is then split off into smaller arteries. In the cortex the glomerular capsule gets divided into a cluster of capillaries which then form to glomerulus. The blood vessels lead to the arterioles (class notes, 2015).
The ureter is a tube that transports the urine from the kidney to the bladder. There are two ureters. One of the ureters is attached to each kidney. The upper half of the ureter is located in the abdomen and the lower half is located in the pelvic area. The ureter is 10-12 inches long. The tube has walls which are thick because they are made of fibrious, muscular and have a mucus coat which enable them to all contract , no date). The ureter is a tube which goes from one kidney to the bladder. It transports the urine from the kidney to the urinary bladder (class notes, 2015)
The bladder is a muscular sac in the pelvis which is just behind the pubic bone. When the bladder is empty, it is the size and shape of a pear. Urine is made in the kidneys. It travels down the two tubes which are called ureters. The bladder stores urine which enables the urine to be infrequent and voluntary. The bladder is lined by the layers of muscle tissue which stretch to suit the urine. During urination, the bladder muscles contract and the two valves open to enable urine to flow out. Urine exits the bladder into the urethra. This then transports the urine out of the body because it passes through the penis or vagina (WebMD, no date). An...
