WHAT ARE THE MAIN STAGES OF WASTE REMOVAL BY THE KIDNEYS?
The kidneys use a transport system called the counter-current mechanism. This pushes water, amino acids, sodium, potassium and glucose out into Bowman's capsule.From Bowman's capsule the proximal convoluted tubule (PCT) descends into the medulla of the kidney and is renamed the descending limb of the loop of Henle.The descending limb can only remove water from the filtrate and no ions. The water is removed passively as the medulla is very salty.The ascending loop of Henle actively pumps sodium and potassium out but water can not follow.The ascending loop is renamed the distal convoluted tubule (DCT) as it passes by the glomerulus. At this spot another structure is found called the juxtaglomerular apparatus.This regulates blood pressure.Eventually the afferent arteriole flows into a capillary bed and that flows into veins to carry the water and other nutrients back to the body.
Which part of the loop of Henle contains more dilute urine?
The thick descending limb contains the most dilute filtrate (it is not called urine at this stage). It become more concentrated as it travels through the loop of Henle. It should be noted that this is not because more solute is added but instead because the water is reabsorbed into the blood along the loop of Henle. The Ascending Loop is the most dilute, because it is permeable to salts not H20, and passes through a Decreasing Salt Barrier. The thick portion of the ascending linb actively pumps Cl ions out of the tubular fluid and into the surrounding tissue. The ascending limb is impermeable to water, however, and so water does not follow the sodium and Cholride by osmmosis. The result is that the tublar fluid becomes more and more dilute as it flows up the ascending limb.
What name is given to an artificial limb?
A prosthetic limb or "prosthetic"
Why is the west limb of the sun red-shifted and the east limb blue-shifted?
Because the sun is rotating. So its west limb is moving away from us and its east limb is moving toward us ... the exact conditions required in order to shift the emission spectrum.
List of two joint muscles in upper and lower limb?
Two joint muscles in the upper limb is the wrist and the elbow. Two joint muscles in the lower limb is the ankle and the knee.
What is the path filtrate as it passes through the nephron?
This is the pathway of filtration, which takes place in the nephron:1-Glomerulus and Bowman's capsule: Filtration of water and dissolved solutes occurs as the blood is forced through the walls of glamerulus into the Bowman's capsule by fluid pressure in the capillaries ( capillary beds).2-Proximal tubule: Selective reabsorption of nutrients from filtrate back into blood by active and passive transport.3-Descending limb of loop of henle: This is permeable to water resulting in loss of water from filtrate by osmosis. Salt becomes concentrated in the filtrate as descending limb penetrates inner medulla of kidney.4-Ascending limb of loop of henle: Thin segment of ascending limb of loop of henle in permeable to salt resulting in diffusion of salt out of ascending limb.5-Distal tubule: Selective reabsorption of nutrients from blood into nephron by active transport.6-Collecting Duct: Urine formation.
Water moves out of the descending limb of the loop of henle due to?
osmosis
What are the main functions of the Loop of Henle in urine formation?
absorption of water (from descending limb), absorption of Na+ (from ascending limb)
What part of the nephron monitors the salt level?
Descending Limb Of Loop Of Henle.
How would hypertonic urine be produced from an isotonic blood plasma?
# Water is reabsorbed all along the nephron. # Urine becomes hypertonic (salty) because of the loop of Henle and the collecting duct. # Loop of Henle # The descending limb of the loop of Henle can't absorb salt, and the ascending limb can't absorb water. # Salt passively diffuses out of the lower portion of the ascending limb. # The upper part of ascending limb actively transports salt into tissue of the renal medulla. # Increase in salt in the direction of the inner medulla. # Urea leaks from the lower portion of collecting duct and contributes to a high solute (salt) concentration. # Water leaves descending limb of the loop of Henle, returning to the blood. # Urine is hypertonic to blood.
What is the function of the ascending limb of the loop of henle?
The function of the ascending loop of henle is draw Sodium out of the filtrate. The ability of the ascending loop to actively transport sodium into the surrounding tissue is directly related to the amount of water that can be diffused out of the descending loop of henle. (main factor in water re-absorption)
What does a artificial limb have to do with space?
An artificial limb is actually began in space. The robotic arms that they use in space travel today were actually the beginning of artificial limbs.

How do you say cut you from limb to limb in old English?
Perhaps the expression you want is "limb from limb" and not "from limb to limb."

What is the medical term meaning false limb?
A false limb is a prosthetic limb.
