What is the histology of the nephron?
The nephron loop is the U-shaped bend of a nephron which extends through the medulla of the kidney. Histologically, it consists of two parts; thin descending and thin ascending limbs. Both limbs are composed of simple squamous epithelium.
What is the normal histology of kidney?
The normal kidney at low power has a thin connective tissue capsule at the left with underlying renal cortex which here contains a glomerulus and surrounding tubules with cuboidal epithelium.
What are the 4 main functions of a nephron?
The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion.
What are the tubular elements of the nephron?
The tubular system consists of the proximal tubules, the descending and ascending loops of Henle, the distal tubules, and the collecting ducts. Each glomerulus is physically connected to a single, continuous tubular system up to the level of the collecting duct, which receives urine originating from multiple nephrons.
How filtrate flows through the nephron?
The filtrate flows from the proximal tubule and into the Loop of Henle. The loop of Henle concentrates the filtrate, by removing more water from it, and passes it to the distal tubule. From the distal tubule it travels to the collecting duct – now called urine.
What types of cells line the nephron?
The epithelium of these tubules consist of cuboidal or columnar cells. They empty into collecting ducts that are easy to recognise, because they have large lumens, with pale staining columnar epithelium.
What is a nephron and name five main components of a nephron?
A nephron is a coiled tubule that has renal corpuscle and renal tubules as its components. Generally, a nephron consists of six parts, i.e., Glomerulus, Bowman’s capsule, Proximal convoluted tube, Loop of Henle, Distal convoluted tube, and the collecting duct.
Where is nephron located in kidney?
The nephrons are located in the cortex and medulla of the kidney. The cortex contains the renal corpuscle, distal convoluted tubule and proximal convoluted tubule. Whereas, the medulla contains the loop of Henle and collecting ducts.
Which part of the kidney contains nephrons?
The renal medulla contains the majority of the length of nephrons, the main functional component of the kidney that filters fluid from blood.
