Outer Section Of The Kidney

The renal columns are connective tissue extensions that radiate downward from the cortex through the medulla to separate the most characteristic features of the medulla the renal pyramids and renal papillae.

Outer section of the 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. Cortex outer kidney region that is composed of glomeruli bowman s capsule and proximal distal convoluted tubules medulla inner kidney region that is composed of collecting ducts and the loops. The renal cortex is the outer part of the kidney.

The renal cortex is surrounded on its outer edges by the renal capsule a layer of fatty tissue. The kidneys are the main organs of the urinary system. They function chiefly to filter blood in order to remove wastes and excess water.

The kidneys also reabsorb and return to the blood needed substances including amino acids sugar sodium potassium and other nutrients the kidneys filter about 200 quarts of blood per day and produce about 2. The outer renal cortex and the inner renal medulla grossly these structures take the shape of eight to 18 cone shaped renal lobes each containing renal cortex surrounding a portion of medulla called a renal pyramid. The functional substance or parenchyma of the kidney is divided into two major structures.

Urine passes into this pelvis from. It contains the glomerulus and convoluted tubules. Longitudinal section of the kidney shows following parts.

As the ureter enters the kidney it enlarges into a cavity the renal pelvis. Other articles where renal cortex is discussed. The waste and water are excreted as urine.

Between the renal pyramids are projections of cortex called renal columns.
