Match each part of a nephron with its function. sets the stage for this enthralling narrative, offering readers a glimpse into a story that is rich in detail and brimming with originality from the outset.
The nephron, the functional unit of the kidney, plays a crucial role in maintaining the body’s fluid and electrolyte balance. Each nephron consists of several distinct segments, each with a specific function in the process of urine formation. Understanding the function of each part of the nephron is essential for comprehending the overall functioning of the kidney and its role in maintaining homeostasis.
Match each part of a nephron with its function: Match Each Part Of A Nephron With Its Function.
The nephron is the functional unit of the kidney. It is responsible for filtering blood, reabsorbing essential nutrients, and excreting waste products. The nephron consists of several parts, each with a specific function.
Glomerulus
The glomerulus is a network of tiny blood vessels that filters blood. The glomerulus is located in the Bowman’s capsule, which is the first part of the nephron. The glomerulus filters blood by allowing water, salts, and small molecules to pass through, while preventing larger molecules, such as proteins, from passing through.
Bowman’s Capsule
The Bowman’s capsule is a cup-shaped structure that surrounds the glomerulus. The Bowman’s capsule collects the filtrate from the glomerulus and sends it to the proximal convoluted tubule.
Proximal Convoluted Tubule (PCT)
The proximal convoluted tubule is the first part of the nephron after the Bowman’s capsule. The PCT reabsorbs essential nutrients from the filtrate, such as glucose, amino acids, and vitamins. The PCT also secretes waste products into the filtrate.
Loop of Henle, Match each part of a nephron with its function.
The loop of Henle is a U-shaped structure that extends from the PCT. The loop of Henle is responsible for concentrating the filtrate. The descending limb of the loop of Henle is permeable to water, but not to salts. As the filtrate descends down the descending limb, water moves out of the filtrate and into the surrounding tissue.
The ascending limb of the loop of Henle is impermeable to water, but permeable to salts. As the filtrate ascends up the ascending limb, salts move out of the filtrate and into the surrounding tissue.
Distal Convoluted Tubule (DCT)
The distal convoluted tubule is the last part of the nephron before the collecting duct. The DCT fine-tunes the composition of the filtrate. The DCT reabsorbs or secretes ions, such as sodium, potassium, and chloride, to regulate the pH and electrolyte balance of the filtrate.
Collecting Duct
The collecting duct is the final part of the nephron. The collecting duct collects the filtrate from the DCT and sends it to the ureter. The collecting duct also reabsorbs or secretes water to regulate the concentration of the urine.
FAQ Explained
What is the primary function of the glomerulus?
The glomerulus is responsible for filtering waste products and excess water from the blood, forming the initial filtrate that enters the nephron.
How does the proximal convoluted tubule contribute to urine formation?
The proximal convoluted tubule reabsorbs essential nutrients, ions, and water from the filtrate, modifying its composition.
What is the role of the loop of Henle in urine concentration?
The loop of Henle creates a concentration gradient in the kidney medulla, allowing for the reabsorption of water and the excretion of concentrated urine.
