The Anatomy of a Kidney The kidneys are reddish-brown, bean-shaped organs situated retroperitoneal on the posterior abdominal wall. They extend from lumbar vertebra T12-L3. Normally the kidney is about the size of a mouse and measures approximately 11-12 cm in length, 5-6 cm in width and 2.5-3 cm in thickness.The kidneys have a superior and inferior pole, medial and lateral margins, and an anterior and posterior surface. The superior pole of each kidney is deep to the rib cage.or the right kidney, its superior pole is at the 12th rib and for the left the superior pole is at ribs 11 and 12. Anatomy of Kidney. On the medial margin of the kidney is concave region called the renal hilus.

Renal pyramids Renal pyramids are kidney tissues that are shaped like cones. Another term for renal pyramids is malpighian pyramids. Between seven and eighteen pyramids exist in the innermost part of the kidney, which is called the renal medulla; in humans, there are usually only seven of the pyramids. The base of each pyramid faces the outer portion of the kidney, which is called the renal cortex. The renal cortex is located between the renal medulla and the renal capsule. The renal capsule is defined as the layer that surrounds the kidneys with tough fibrous tissue. The capsule is covered in a connective fatty tissue.

- Each kidney has a prominent medial indentation called the hilus which serves as the entry point of blood vessels, nerves and ureter. At the hilus an inner layer of the renal capsule extends into an internal cavity of the kidney called the renal sinus. This cavity is filled with blood vessels, nerves, and the tributaries of the collecting system that eventually form the ureters.

The Structure of a Kidney Nephron The renal tubule is the part of the kidney nephron into which the glomerular filtrate passes after it has reached the Bowman's capsule. The first part of the renal tubule is called the proximal convoluted tubule (PCT), which is shown on the right-hand side of the diagram above.ithin the glomerulus are glomerular capillaries that are located between the afferent arteriole bringing blood into the glomerulus and the efferent arteriole draining blood away from the glomerulus. The (outgoing) efferent arteriole has a smaller diameter than the (incoming) afferent arteriole.

Transitional Cell Cancer of the Renal Pelvis and Ureter Treatment (PDQÂ®)âPatient Version Transitional cell cancer of the renal pelvis and ureter is a disease in which malignant (cancer) cells form in the renal pelvis and ureter. The renal pelvis is the top part of the ureter. The ureter is a long tube that connects the kidney to the bladder. There are two kidneys, one on each side of the backbone, above the waist. The kidneys of an adult are about 5 inches long and 3 inches wide and are shaped like a kidney bean.

What are the parts of the kidney? Portions of the renal cortex extend into the spaces between adjacent pyramids to form renal columns. The cortex and medulla make up the parenchyma, or functional tissue, of the kidney. The central region of the kidney contains the renal pelvis, which is located in the renal sinus, and is continuous with the ureter.he outer, reddish region, next to the capsule, is the renal cortex. This surrounds a darker reddish-brown region called the renal medulla. The renal medulla consists of a series of renal pyramids, which appear striated because they contain straight tubular structures and blood vessels.

Transitional Cell Cancer (Cancer of the Renal Pelvis and Ureter) The tube that connects the kidneys to the bladder is known as the ureter. Most healthy people have two kidneys and, therefor, two ureters. The top of each ureter is found in the middle of the kidney in an area known as the renal pelvis.Urine collects in the renal pelvis and is drained by the ureter into the bladder. The renal pelvis and the ureter are lined with specific types of cells called transitional cells.These cells are able to bend and stretch without breaking apart. When cancer develops in the renal pelvis or ureter, it begins in the transitional cells. This type of cancer is known as malignant neoplasm of the ureter.rine collects in the renal pelvis and is drained by the ureter into the bladder. The renal pelvis and the ureter are lined with specific types of cells called transitional cells. These cells are able to bend and stretch without breaking apart.

The Kidney: Major Divisions & Structures The outer portion of the kidney located in between the renal capsule and the renal medulla is called the renal cortex. The renal cortex is like the fleshy part of the avocado. Deeper to the renal cortex, like our avocado pit, is the inner portion of the kidney, called the renal medulla.ortex and Medulla. Our kidneys are a multilayered structure, kind of like an avocado. If you've ever sliced an avocado in half, you'd have a middle layer, the avocado pit, and then a surrounding outer layer that is the edible part of the avocado. Likewise, your kidneys have an outer and an inner layer.

The Anatomy of a Kidney The cortex is the superficial outer layer of the kidney located underneath the capsule. The medulla is the inner layer and it extends from the renal cortex to the renal sinus. The medulla is divided into various cone-shaped structures called the renal pyramids. The renal pyramids extend from the cortex to the renal papilla. These papillae extend into a space called the renal pelvis.
