Nephron Processes Tournament

Study the proximal-tubule figure, then eight TEAS rounds: where filtration happens, reabsorption vs secretion, the tubule sequence, segment jobs, percent reabsorbed, ADH and aldosterone, and what is not a nephron process.

Nephron processes in 60 seconds

Filtration at the glomerulus. Reabsorption tubule → blood. Secretion blood → tubule.

The PCT does the bulk work. The loop builds the medulla. DCT and collecting duct listen to ADH (water) and aldosterone (Na+/K+).

About 99% of filtrate is reabsorbed. Urine is what is left after those three processes.

Direction is the TEAS trap. Reabsorption is tubule → blood (you are keeping it). Secretion is blood → tubule (you are dumping it). Filtration only happens at the glomerulus.

FAQ

What are the three nephron processes on the TEAS?

Filtration at the glomerulus, reabsorption (tubule to blood), and secretion (blood to tubule). Ureter peristalsis moves urine after the nephron is finished — it is not a fourth nephron process.

What do ADH and aldosterone do?

ADH inserts aquaporins in the collecting duct so water is reabsorbed and urine volume falls. Aldosterone increases Na+ reabsorption and K+ secretion in the distal nephron; water follows sodium, so urine volume also falls.

How much filtrate is reabsorbed?

About 99%. The proximal tubule does the bulk of solute and water work. The loop builds the medullary gradient. Distal segments fine-tune under hormones.

Do I need an account to play the nephron game?

No. Browser-based, no email gate, public leaderboard.
