I encapsulate (surround) the glomerulus and catch the filtrates that are pushed out of blood.

This is where salt and water are reabsorbed

Hint it connects the PCT to the DCT

What tubule is directly connected to the collecting duct?

This is where water balance takes place-the last chance before it exits the body as urine.

What is the proximal convoluted tubule?

what are the main components of urine

water, urea, creatinine, salts

What are 2 processes that are involved in kidney filtration and reabsorption?

What is diffusion and active transport

What are the main organs of the urinary system?

kidneys bladder ureter urethra

We are the three main parts/ areas of the kidney.

What are the medulla, the cortex, and the renal pelvis?
