What is the main structure of the kidney?

Inside the kidneys are a number of pyramid-shaped lobes. Each consists of an outer renal cortex and an inner renal medulla. Nephrons flow between these sections. These are the urine-producing structures of the kidneys.

What is the structure and function of the kidney?

The kidneys filter the blood to remove waste products, which they convert into urine. Urine is carried from each kidney, through a tube called a ureter to the bladder, where it is stored. The ureter and blood vessels enter and exit the kidney through the renal hilum.

What type of structure is a kidney?

Kidneys: The Main Osmoregulatory Organ. The kidneys are a pair of bean-shaped structures that are located just below and posterior to the liver in the peritoneal cavity. Adrenal glands, also called suprarenal glands, sit on top of each kidney.

What are the main function of the kidneys?

Their main job is to cleanse the blood of toxins and transform the waste into urine. Each kidney weighs about 160 grams and gets rid of between one and one-and-a-half litres of urine per day. The two kidneys together filter 200 litres of fluid every 24 hours.

What are the primary function of kidneys?

What are the 10 functions of the kidney?

KIDNEYS

• Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.
• Regulation of osmolarity.
• Regulation of ion concentrations.
• Regulation of pH.
• Excretion of wastes and toxins.
• Production of hormones.

What is the external structure of the kidney?

External structure: Each kidney is reddish-brown, bean shaped organ and is about 4 inches long and 2 inches wide. It has a medial concave surface and a lateral convex surface. On the medial concave border of each kidney, there is a vertical slit called hilum, which is bounded by thick lips of the renal substance.

What are the parts of the kidney and their functions?

The kidney is a critical organ in the body’s renal system. Some of the larger components in the anatomy of the kidney include the renal pelvis, renal medulla, and renal cortext. Kidneys aid in filtering toxins and maintaining fluid balance. In addition to these functions, the kidneys play other important roles in maintaining health.

What are the three regions of the kidney?

The renal cortex, renal medulla, and renal pelvis are the three main internal regions found in a kidney. Nephrons, masses of tiny tubules, are largely located in the medulla and receive fluid from the blood vessels in the renal cortex.

Is the renal cortex the inner portion of the kidney?

Renal cortex is the outer part of the kidney whereas renal medulla is the inner deeper part of kidney. They do also differ in the presence of nephron’s. Cortical nephron’s are present in cortex and juxtamedullary nephrons are present mostly in medulla with a small part present in inner cortex.
