Thank you for participating today @silent.nightowl

The proximal tubule is the first part of the kidney tubule after the blood is filtered.

It’s where the body reabsorbs almost all the glucose (sugar) from the filtered fluid, so it doesn’t get lost in urine.


🧠 Simple explanation:

Blood is filtered in the kidney.

Sugar goes into the filter.

The proximal tubule quickly pulls the sugar back into the blood.

This prevents sugar loss — unless the blood sugar is too high (like in diabetes).
