A nephron is the microscopic structural and functional unit of the kidney that filters blood and produces urine. Each kidney contains over one million nephrons, which filter waste products from the blood, reabsorb needed substances, and excrete excess water and salts. This process helps maintain the body's fluid balance, blood pressure, and overall homeostasis.  

A nephron is the basic structural and functional unit of the kidney that filters blood, reabsorbs needed substances, and excretes waste as urine. Each of the millions of nephrons in the kidneys consists of a network of blood vessels called the glomerulus and a long tubule. The process involves filtering blood in the glomerulus, then reabsorbing water and nutrients in the tubules, and finally excreting the remaining waste.

Which part of the nephron is closest to the collecting duct?

Glomerulus

MY ANSWER

The glomerulus is not closest to the collecting duct.

Loop of Henle

The loop of Henle is not closest to the collecting duct.

Bowman's capsule

Bowman's capsule is not closest to the collecting duct.

Distal convoluted tubule

The distal convoluted tubule is closest to the collecting duct.
