Definition

Kidney

One of a pair of organs located in the right and left side of the abdomen. The kidneys remove waste products from the blood and produce urine.

Retroperitoneally

refers to the back of the peritoneum, the membrane that lines the anatomical space in the abdominal cavity

Renal Sinus

The renal sinus is a fatty compartment located within the medial aspect of the kidney. It communicates with the perinephric space.

Renal Pelvis

The area at the center of the kidney. Urine collects in the renal pelvis and is funneled into the ureter.

Renal Medulla

The 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. Blood enters into the kidney via the renal artery, which then splits up to form the interlobar arteries.

Renul Cortex

the granular outer layer of the kidney, composed mainly of glomeruli and convoluted tubules, extending in columns between the pyramids that constitute the renal medulla. striate cortex part of the occipital lobe that receives the fibers of the optic radiation and serves as the primary receiving area for vision .

Nephrons

The nephron is the fundamental functional unit of the kidney and can be thought of as a long tube of variable thickness which winds a set path through the kidney.

Renal arteries

two blood vessels leading off from the abdominal aorta that go to the kidneys. The renal artery is one of these two blood vessels. The renal artery enters through the hilum, which is located where the kidney curves inward in a concave shape.

Renal Vein

The short thick veins which return blood from the kidneys to the vena cava .

Renal tubule

the part of the kidney's nephron that leads from the glomerulus to the collecting tubules. It consists of a looping segment and two convoluted sections. These canals resorb selected materials back into the blood and secrete, collect, and conduct urine.

Glomerulus

A tuft of capillaries situated within a Bowman's capsule at the end of a renal tubule in the vertebrate kidney that filters waste products from the blood and thus initiates urine formation.

Glomerular capsule

Renal Corpuscle

also called malpighian body, filtration unit of vertebrate nephrons, functional units of the kidney. It consists of a knot of capillaries (glomerulus) surrounded by a double-walled capsule (Bowman’s capsule) that opens into a tubule. Blood pressure forces plasma minus its macromolecules (e.g., proteins) from the glomerular capillaries into the Bowman’s capsule

Efferent arteriole

is a branch of the renal artery, which carries filtered blood back to the circulation. The blood pressure of the afferent arteriole is high, facilitating the ultra-filtration of blood plasma at the glomerulus.

Peritubular capillary

Glomerular apparatus

Glomerular filtration

Tubular reabsorption

Tubular secretion

Urine

a watery, typically yellowish fluid stored in the bladder and discharged through the urethra. It is one of the body's chief means of eliminating excess water and salt, and also contains nitrogen compounds such as urea and other waste substances removed from the blood by the kidneys.
