Question

select all that apply
choose all the processes by which urine is formed.

tubular transport
tubular reabsorption
tubular secretion
filtration

Explanation:

Urine formation involves three main processes. Filtration occurs in the glomerulus where blood is filtered. Tubular reabsorption is when useful substances like glucose, water, and ions are reabsorbed back into the blood from the filtrate. Tubular secretion is the active transport of substances (e.g., certain ions, drugs) from the blood into the tubular fluid. Tubular transport is a more general term and not one of the specific named processes for urine formation in standard physiology.

Answer:

B. tubular reabsorption, C. tubular secretion, D. filtration
