Each kidney is composed of numerous complex tubular structure called nephrons, which are the functional units of kidneys. 134. In humans, a healthy adult has 1 to 1.5 million nephrons in each kidney, functioning together to filter blood from all its impurities. They receive and transmit signals to different parts of the body. This filterate contains glucose, amino acids, urea, uric acid, salts and a major amount of water. It consists of a tubule that is connected with collecting duct at one end and a cup-shaped structure at the other end. (i) Functioning of nephron: Filtration of blood takes in Bowman’s capsule from the capillaries of glomerulus. As the ultrafiltrate molecules travel down the tubules they become more and more hypertonic, which results in more amount of water to be extracted from the ultrafiltrate before it exits the nephrons.

This discussion on Explain the structures of nephron? The second part is called the loop of Henle, or nephritic loop because it forms a loop (with descending and ascending limbs) that goes through the renal medulla. Every Bowman's capsule contains a cluster of capillaries, called 'Glomerulus', within the cup-shaped structure. NCERT Solutions For Class 10. If you're seeing this message, it means we're having trouble loading external resources on our website. The filterate passes into the tubular part of the nephron. The filterate which remained after reabsorption is called urine. Since the electrolytes get reabsorbed at the ascending loop of Henle, the filtrate gets diluted as it moves towards the ascending limb. These have long loops of Henle and extend into the medulla. The blood is brought into the kidney by the glomerulus. A nephron consists of a filter called glomerulus and a tubule. Class 6th to Class 10th and Intermediate Subjects Packs are available.

First one is a cup-shaped bag at its upper end which is called Bowman's capsule. I'm going to draw for you two of the most important organs in her body and actually on the left and right side of our body that pretty much look like that like little kidney beans in fact that's what they are they're kidneys and so we have some arteries the renal arteries that flow into them and renal is just another word referring to kidneys and we've got renal veins with blood flowing back out of them so once the blood is headed back to the heart we call it a renal vein and there are two of them and probably the most important part about these kidneys certainly the thing that makes them really unique is that they have these ureters and these your atures drain urine into a bladder and actually I'll draw that right here that's the bladder and the ureters are the third tube coming out of our kidneys and then when you're ready to urinate you can release all that urine from your bladder into the outside world and so there are three basic things that I want you to remember coming into and out of kidneys the renal arteries and the renal veins and the ureter now to really make sense of it you got to think about how the artery might split up so let's say we go back to the artery and you follow it it starts kind of branching let's say makes five little branches and then might have more branches off of those branches and finally maybe even some more branches and eventually it's not even an artery anymore right all these little branches are so tiny you would call them arterioles and let's just take this arteriole this little guy and let's see what happened so let's say I take that little guy and show you on the left side of the screen what that would look like so let's take a look at this arterial a little bit closer so this is our a parent arteriole a capitalised and it's called a fin because it's headed toward something a pinched arterial and let's not forget where it comes from it's coming from the renal artery so it's coming from the renal artery headed towards something that something is this the artery or the arterial rather starts making a lot of little turn backs on itself and finally straightens out and when it does we call it the efferent arterial so that's how we keep straight whether it's coming or going from this little network if you want to call it that of blood vessels and in fact this little network of blood vessels if you look under microscope is actually being hugged by something like this this is actually really interesting this is the first time we're taking a look at something that is not a blood vessel in the kidney and it begins our journey of urine so this thing is called the Bowman's capsule Bowman's capsule this is a thing in yellow that I've drawn for you and whenever things are named like this you got a wondering you know who was mr. The glomerulus filters the fluid and waste products holding back the blood cells and large molecules, especially proteins. The word nephron is derived from the Greek word – nephros, meaning kidney. Click ‘Start Quiz’ to begin! In text questions of page 112 ( Life Processes class 10 ) Question 1. Bowman and mr. Each nephron is made up of two main parts: (1) Malpighian Body, (2) Renal tubule. 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. This is carried out in both physical and electrical forms. Xylem vessels and tracheids of the roots, stems and leaves are interconnected to form a continuous system of water-conducting channels reaching all parts of the plant. 232, Block C-3, Janakpuri, New Delhi, Each nephron has two parts - the glomerulus and the renal tubule.
