How does tubular secretion differ from tubular reabsorption?

Tubular secretion involves the movement of substances from the filtrate into the blood, while tubular reabsorption involves the opposite.

Tubular secretion occurs only in the glomerular capsule, while reabsorption occurs throughout the nephron.

Tubular secretion involves the addition of substances from the blood into the filtrate, whereas reabsorption involves reclaiming substances from the filtrate back to the blood.

Tubular secretion is responsible for forming the initial filtrate, whereas reabsorption removes waste products.
