Structure of nephron

Nephrons: The Functional Units of the Kidney. Nephrons take a simple filtrate of the blood and modify it into urine. Nephrons are the “functional units” of the kidney; they cleanse the blood and balance the constituents of the circulation. Each kidney is made up of over one million nephrons that dot the renal cortex, giving it a granular appearance when sectioned sagittally. Many changes take place in the different parts of the nephron before urine is created for disposal. The term forming urine will be used hereafter to describe the filtrate as it is modified into true urine. The principle task of the nephron population is to balance the plasma to homeostatic set points and excrete potential toxins in the urine. They do this by accomplishing three principle functions—filtration, reabsorption, and secretion. They also have additional secondary functions that exert control in three areas: blood pressure (via production of renin), red blood cell production (via the hormone EPO), and calcium absorption (via conversion of calcidiol into calcitriol, the active form of vitamin D). Tubular parts of a Nephron – converts the filtrate into urine • The Bowman’s capsule / Glomerular capsule: The Bowman’s capsule (also called the glomerular capsule), is the beginning of a nephron. It surrounds the glomerulus. It is a double walled cup, It is composed of inner visceral and outer parietal layers. Parietal (outer) layer of glomerular capsule is simple squamous epithelium. Visceral (inner)...

Overview Bowman’s capsule is part of the nephron, which is the filtering unit of your kidney. What is Bowman’s capsule? Bowman’s capsule is a part of the nephron which is a part of your Every nephron has a glomerulus, which is a group of tiny Bowman’s capsule is known by other names, including the glomerular capsule, the Malpighian capsule and the renal corpuscular capsule. Bowman’s space also has other names, including glomerular capsule space, filtration space and urinary space. Function What does Bowman’s capsule do? Bowman’s capsule and the glomerulus make up the renal corpuscle. They are all parts of the kidney. Your kidneys have many important jobs, including controlling the pH balance of your blood, regulating blood pressure and maintaining The capsule helps the glomerulus to filter blood. Small molecules from the blood pass freely into Bowman’s space, but as long as the kidney filter is working normally, cells and large proteins stay in the blood. The small molecules then pass through tubes in the kidney, and the kidney regulates which molecules get absorbed back into your blood and which leave your body in urine. Anatomy Where is Bowman’s capsule located? Bowman’s capsule is located in the renal cortex, part of your kidney. The kidneys are located below your ribcage and behind your belly. Usually, there is one kidney on either side of your spine. The kidneys reside between your intestines and diaphragm. Each kidney is connected to your bladder by a tube called a u...

Ranaa Aboumosallam Arafat I took pre-masters and diploma in Microbiology, Human Physiology and Endocrinology. I got accepted to start my masters next fall at the University of Manitoba in Biology. I wrote lessons for Michigan virutal and I worked as a biology teacher for one year. Moreover, I wrote scientific explainers and presentations for several educational platforms. • Instructor There are three parts to nephrons: 1- Renal corpuscular consists of the glomerulus and bowman's capsule and has a role in blood filtration. 2- Renal tubules consist of distal and proximal convoluted tube and loop of Henle and have a role in reabsorption of essential nutrients back to the blood. 3- Collecting duct collects urine and passes it to the ureters to be expelled later through the urethra. Kidneys The kidneys are two small organs that do one big job: filter the blood to create urine. Hopefully, you already take a moment to appreciate your kidneys each time you're in the bathroom, but if not, this lesson will help nudge you into giving the kidneys the credit they deserve. Within the kidneys, you have tiny, microscopic structures called nephrons. If the kidneys are urine-making factories, the nephrons are the workers within those factories who actually make the urine. You have approximately one million nephrons per kidney doing the job of filtering the blood and producing urine. We're going to take a close look at the nephron and what occurs within them to make that wonderful urine we e...
