What is the part of the renal tubule function is filtration of blood?
Filtration of blood occurs in the glomerulus, which is the initial part of the renal tubule where blood is filtered to form a fluid called glomerular filtrate. This process is responsible for removing waste products, excess ions, and water from the blood to form urine.
Which is the correct path of filtered blood through the kidney?
From the renal corpuscle (first the afferent arteriole feeds the glomerulus, which is then drained by the efferent arteriole) and passes on to the renal tubules (passes into the proximal convoluted tube, into the descending and ascending loops of Henle, and the distal convoluted tube)
What is a cortex of a kidney?
i have no idea :) i thing it does something
What part of the renal tubule has an elaborate countercurrent mechanism for reabsorption of sodium and water?
The loop of Henle has an elaborate countercurrent mechanism for reabsorption of sodium and water in the renal tubule. This mechanism allows for the generation of a concentration gradient that helps in the concentration of urine.
What are nephrons made up of?
Each one consists of a renal corpuscle and a renal tubule which carry out the functions of the nephron. The renal tubule consists of the convoluted tubule and the loop of Heinle http://coe.fgcu.edu/Faculty/GreeneP/kidney/nephron.html.
How do my kidneys use water?
The kidney is pretty much an organic filter. As the blood in a body rushes through the arteries, it makes its way around the entire body. When it flows through the renal artery, then that blood will end up at the kidney. The first stage of the kidney process, is to filter out the blood cells and protein molecules by pushing the bodily fluids through the glomerulus (filter) which allows water, glucose, salts, and urea to pass, but does not allow the blood cells and protein to pass, as they are too big. The blood cells and proteins the flow the the capillaries around the renal tubule (the part of the kidney that the rest of the fluid flows through) in order to enter back into the rest of the body through the renal vein. As the remaining fluid filters through the renal tubule, the glucose and most of the the water and salts leave through the capillaries in the renal tubule in order to join the blood in the renal vein and keep it enriched. What is left is some water, salts, urea, and other undesired substances which continue to flow through the renal tubule until they enter the bladder and leave the body in the form of urine.The chemicals that are kept or lost are the way that the kidneys controls water balance.The kidneys help balance the chemicals in your blood, such as sodium, potassium and calcium. "Water follows salt" is a good way to remember this. If the body needs to lose water, salt will be excreted by the kidney and the water will follow along. The opposite is true if the body needs to hold on to water.The kidneys' most important job is to filter liquid waste from the blood and getting rid of it in the form of urine by using filters called nephrons.There are many videos on how the kidney works at the link below.
Where is the primary site at which tubular secretion occur?
Tubular secretion is a part of urine formation occurring within the nephrons of the kidneys. After glomerular filtration, in which fluids from the blood pass into the glomerular capsule of the renal tubule, the filtrate is subject to tubular reabsorption and tubular secretion within the convoluted tubules and collecting ducts of the nephrons.
What does high concentration NaCl in the renal tubule at the JGA most likely indicate?
High concentration of NaCl in the renal tubule at the juxtaglomerular apparatus (JGA) is likely to trigger the release of renin, a hormone that plays a key role in regulating blood pressure and kidney function. This response is part of the renin-angiotensin-aldosterone system, which helps to maintain blood pressure and electrolyte balance in the body.
What is the process that is performed by the glomerulus that forms blood plasma without blood proteins?
Glomerular Filtration - a passive process in which fluid passes from the blood into the glomerular capsule (part of the renal tubule) Once in the capsule the fluid is called filtrate and is essentially blood plasma without proteins
Which body part filters blood and wastes from entering the kidney?
The body part that filters blood and wastes before they enter the kidney is the nephron. Each kidney contains approximately one million nephrons, which consist of a glomerulus that filters blood and a tubule that processes the filtrate to reabsorb necessary substances and excrete waste. The glomerulus acts as the initial filtration unit, allowing water, ions, and small molecules to pass while retaining larger molecules like proteins and blood cells.
How does the tissue of the kidneys structure to aid in filtration?
Function * Ultrafiltiration: the process by which fluid is filtered out of the blood by the glomerulus. * The blood pressure in a glomerulus causes part of the blood plasma to leak through the capillary walls. The red blood cells and plasma proteins are too big to pass out of the capillary, so the fluid that does filter through is plasma without the protein. The fluid thus consists mainly of water with dissolved salts, glucose, urea and uric acid. * Selective Reabsorption: the process of absorbing back the substances needed by the body. * The filtrate from the glomerulus collects in the renal capsule and trickles down the renal tubule. * As it does so, the capillaries which surround the tubule absorb the substance the body needs back into the blood. * ** The glucose is reabsorbed with much of the water. ** Some of the salts are taken back to keep the correct concentration in the blood. ** *** Salts not needed by the body are left to pass down the kidney tubule with the urea and uric acid. *** They continue down the renal tubule into the pelvis of the kidney, passes down the ureter and to the bladder.
Do the tubule cells of the kidneys excrete bicarbonate ions and retain hydrogen ions become to acidic?
Yes, the tubule cells of the kidneys can secrete bicarbonate ions and retain hydrogen ions to help regulate blood pH when it becomes too acidic. This process occurs in the renal tubules as part of the kidney's role in maintaining acid-base balance in the body.
