What is the function of the renal cortex quizlet?

What is the function of the renal cortex quizlet?

The renal cortex receives most of the blood flow, & is mostly concerned with reabsorbing filtered material. The medulla is a highly metabolically active area, which serves to concentrate the urine. The renal pelvis is a funnel shaped reservoir that collects the urine and passes it to the ureter for excretion.

Does the kidney have a cortex?

The renal cortex is the outer part of the kidney. It contains the glomerulus and convoluted tubules. The renal cortex is surrounded on its outer edges by the renal capsule, a layer of fatty tissue.

What is the cortex and medulla of the kidney?

Renal cortex and renal medulla are two zones of the kidney. Renal cortex consists of glomeruli, Bowman’s capsules, and proximal and distal convoluted tubules. Therefore, renal cortex is involved in the filtration of blood. Renal medulla consists of loops of Henle and collecting tubules, which mainly reabsorb water.

What is the main function of the medulla in the kidney?

The main function of the medulla is to regulate concentration of the urine. The urine flows from the collecting ducts into the renal calyces and pelvis, which undergoes unidirectional peristaltic movements to allow drainage of the urine into the downstream ureter and bladder.

What is the difference between the renal cortex and medulla?

Renal medulla is the innermost part of the kidney. It is divided into smaller sections called as renal pyramids. The difference between renal cortex and renal medulla is, the renal cortex is the outer portion of the kidney whereas renal medulla is the innermost part of the kidney.

What is the renal cortex quizlet?

The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla. Each renal papilla is surrounded by a branch of the renal pelvis called a calyx. The major function of the renal pelvis is to act as a funnel for urine flowing to the ureter.

What is cortex?

when used generally, the term cortex (which is Latin for “bark”) refers to the outermost layer of a structure. When referring to the brain, cortex most often refers to the cerebral cortex, although the cerebellum also has an outer layer called the cerebellar cortex.

What is cortex and medulla?

renal medulla: The inner-most region of the kidney, arranged into pyramid-like structures, that consists of the bulk of nephron structure. renal cortex: The outer region of the kidney, between the renal capsule and the renal medulla, that consists of a space that contains blood vessels that connect to the nephrons.

What is a cortex in anatomy?

In anatomy and zoology, the cortex (plural cortices) is the outermost (or superficial) layer of an organ. Organs with well-defined cortical layers include kidneys, adrenal glands, ovaries, the thymus, and portions of the brain, including the cerebral cortex, the best-known of all cortices.

Is the renal columns part of the medulla or cortex?

The renal column (or Bertin column, or column of Bertin) is a medullary extension of the renal cortex in between the renal pyramids. It allows the cortex to be better anchored. Each column consists of lines of blood vessels and urinary tubes and a fibrous material.

Why is the cortex of the kidney dark?

The renal cortex is the outer layer of the kidney tissue. It is darker than its underlying renal medulla because it receives over 90% of the kidney blood supply. The cortex has a grainy appearance, as it mostly contains ovoid and coiled parts of the nephrons (renal corpuscles and convoluted tubules).

What is found in the renal cortex?

function in kidney somewhat granular outer section (the cortex), containing the glomeruli and convoluted tubules, and a smooth, somewhat striated inner section (the medulla), containing the loops of Henle and the collecting tubules.

How is the cortex different from the medulla in the kidney?

The main difference between renal cortex and renal medulla is that renal cortex is the outer region of the kidney which contains blood vessels connected to the nephrons whereas renal medulla is the inner region of the kidney which contains 8-12 renal pyramids.

What is the normal renal cortex measurement?

The normal adult kidney measures approximately 13 cm in length and 4-6 cm in width. The thickness of the renal cortex can be 12 mm. The renal pelvis measures about 4 cm in length.

What is found only in the renal cortex?

Renal Cortex refers to the part of the kidney that contains the glomeruli and the proximal and distal convoluted tubules. It is covered by the renal fascia and the renal capsule. Since renal cortex contains structures of the nephrons, it is considered as a granular tissue. This smooth, continuous layer of the kidney filters blood.

Is secretion function of the kidneys?

The kidneys remove waste products and excess water from the body and so help to regulate blood pressure . They activate vitamin D, which helps to maintain strong bones, and produce erythropoietin , a hormone that is vital for the production of red blood cells.
