Human kidney dark red and has a form where one side convex or rounded, and the other side concave or curved inward. Human kidney approximately 10-13 cm in length and about 5 to 7.5 cm wide. Kidney adults about the size of a computer mouse. Kidneys were below the diaphragm and behind the peritoneum. The kidneys are located in front of the back wall of the abdomen, on either side of the spine. The kidneys are located below the middle of the back, below the liver on the right side and below the spleen on the left side.
Kidney function excessive waste substances from the blood and form urine. Kidney bean shaped and concave medial surface is called renal hilum.
1. Renal arteries are channels that carry blood from the heart to the kidneys.
2. Renal vein is a channel that transports blood from the kidneys to the heart.
3. The cortex is the outer portion of the kidney.
4. Medulla is the inner lining of the pelvis after and before the renal cortex. Renal medulla is divided into several sections, known as renal pyramids.
5. Renal pelvis is the innermost part of the kidney.
6. Calix is a branch of the pelvis Renis.
Nephron is the functional units of the kidney, amounting to more than 1 million per kidney, the nephron is also the beginning of the formation of urine.
1. The glomerulus is a capillary tuft that made the first step in filtering blood to form urine.
2. Bowman's capsule consists of a layer of parietal (Foreign) and visceral layer (direct glomerular capillary wrap)
3. Renal hilum is mesuk and exit of a number of channels, such as blood vessels, lymph vessels, nerves and ureter.
4. Convoluted tubule Proximal tubule part out of the Renal corpuscles.
5. Henle Descending channels.
6. Ansa Hanle is a channel that delivers primary urine leading to convoluted distal tubules.
7. Henle Ascending channels.
8. Distal convoluted tubule is the section located in the renal cortex. The function of this part also plays a role in urine concentration due to the addition of residual substances and urea.
9. Koligen duct consists of a series of tubules and ducts that connect the nephrons to the ureter. Function are channeled koligen urinary duct of the nephron into the pelvis ureter with minimal water absorption is influenced by antidiuretic hormone (ADH).
10. Afferent arteriole carries blood to the glomerulus to filtered urine early in the process of formation.
11. Efferent arteriole carries blood out of the glomerulus to be distributed throughout the body.
