 Urinary System |
Is also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys

|
Renal System
|
It's purpose is to eliminate wastes from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.
|
 Kidney |
Are bean-shaped organs that serve several essential regulatory roles in vertebrates.They regulate the balance of electrolytes in the blood.
|
|
Retroperitoneal Position
|
Means posterior to the parietal peritoneum, against the posterior wall of the abdomen.
|
 Renal Hilum |
Its recessed central fissure where its vessels, nerves and ureter pass.
|
 Renal Cortex |
Is the outer portion of the kidney between the renal capsule and the renal medulla.
|
 Renal Medulla |
Is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids.
|
 Renal Pyramids |
Are located inside the inner kidney. They consist of tubules, which collect urine from the outer kidneys and transfer them to the calyces, which store urine before it passes to the ureter and bladder.
|
 Renal Columns or (Bertin Columns) |
Is a medullary extension of the renal cortex in between renal pyramids. Each column consists of lines of blood vessels and urinary tubes and a fibrous material.
|
 Renal Papilla of Pyramid |
Is the location where ther enal pyramids in the medulla empty urine into the minor calyx in the kidney. Transitional epithelium begins to be seen.
|
 Renal Corpuscle(s) |
Is the initial blood-filtering component of a nephron. It consists of two structures: (1) a glomerulus and (2) Bowman's capsule.
|
 Renal Capsule |
Is a tough fibrous layer surrounding the kidney and covered in a thick layer of perinephric adiopose tissue. It provides some protection from trauma and damage.
|
 Renal Pelvis |
Is the basin-like or funnel-like dilated proximal part of the ureter in the kidney. In humans, the renal pelvis is the point of convergence of two or three major calyces.
|
 Major Calyces |
Are chambers of the kidney through which urine passes.
|
 Minor Calyces |
Are chambers of the kidney through which urine passes. The minor calyces surround the apex of the renal pyramids.
