what is the function of the fibrous capsule in the kidney?
279805
Renal capsule, thin membranous sheath that covers the outer surface of each kidney. The capsule is composed of tough fibres, chiefly collagen and elastin (fibrous proteins), that help to support the kidney mass and protect the vital tissue from injury.

The glomerulus is responsible for blood filtration and is composed of a tuft of capillaries whose endothelial cells are interconnected with specialized renal visceral epithelial cells, called podocytes, and with mesangial cells.

The primary function of nephron is removing all waste products including the solid wastes, and other excess water from the blood, converting blood into the urine, reabsorption, secretion, and excretion of numerous substances.

The lobules are held together by a fine, dense, irregular, fibroelastic connective tissue layer extending from the fibrous capsule covering the entire liver known as Glisson's capsule. This extends into the structure of the liver by accompanying the blood vessels, ducts, and nerves at the hepatic hilum.

The main function of the glomerulus is to filter plasma to produce glomerular filtrate, which passes down the length of the nephron tubule to form urine.

State the two vital functions of the human kidney. The two-vital functions of human kidney are: (i) Kidneys act as a excretory organ in human body to remove toxic wastes from the body. (ii) Kidneys also control and maintain water levels in the body.

Most people know that a major function of the kidneys is to remove waste products and excess fluid from the body. These waste products and excess fluid are removed through the urine. The production of urine involves highly complex steps of excretion and re-absorption.

Juxtaglomerular Apparatus. The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and its main function is to regulate blood pressure and the filtration rate of the glomerulus.

Each kidney contains over a million functional units, called nephrons, in the parenchyma (cortex and medulla). A nephron has two parts: a renal corpuscle and a renal tubule.

Filtration. During filtration, blood enters the afferent arteriole and flows into the glomerulus where filterable blood components, such as water and nitrogenous waste, will move towards the inside of the glomerulus, and nonfilterable components, such as cells and serum albumins, will exit via the efferent arteriole.

Capsules are made up of gelatin (hard or soft) and nongelatin shells generally derived from hydrolysis of collagen (acid, alkaline, enzymatic, or thermal hydrolysis) from animal origin or cellulose based.

The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and its main function is to regulate blood pressure and the filtration rate of the glomerulus.

The capsule helps the bacteria to adhere to surfaces, camouflages the bacteria from the immune system by mimicking the host tissues, and makes the bacteria resistant to complement invasiveness. A capsule protects cells from desiccation and toxic metabolites in the environment (heavy metal ions and free radicals).

The nephron is the microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and an encompassing Bowman's capsule. The renal tubule extends from the capsule.
