Which statement correctly describes the function of the tubule in a nephron?
Which statement correctly describes the function of the tubule in a nephron?
- It solely removes excess water from the blood.
- It serves as a storage chamber for urine.
- It processes and adjusts the filtrate before becoming urine. (correct)
- It is responsible for blood cell filtration.
What is the pathway of filtrate after it leaves the glomerulus?
What is the pathway of filtrate after it leaves the glomerulus?
- Filtrate travels through the liver before entering the tubule.
- Filtrate directly enters the renal pelvis for excretion.
- Filtrate is immediately turned into urine in the glomerulus.
- Filtrate travels through the tubule where composition is adjusted. (correct)

Study Notes
Kidney Function
- Nephrons are the functional units of the kidney
- Nephrons remove waste, excess water, and other chemicals from the blood
- Blood enters the nephron, where wastes and excess water are filtered
- Filtered blood is sent back to the body
- Urine exits the nephron and is collected in the bladder
