BIO210Y5 Chapter Notes - Chapter 15: Distal Convoluted Tubule, Urinary Bladder, Pubic Symphysis
Document Summary
Label the places where variable water reabsorption takes place. Variable water reabsorption is water reabsorption/movement in the distal convoluted tubule as well as the ureter where urine is sent to the urinary bladder as well as the urethra. In variable water reabsorption, hormones are involved in how much water reabsorption takes place.

Ureters: muscular tubes from kidneys to urinary bladder. Urinary bladder: hollow muscular organ for temporary storage of urine. Base of urinary bladder between rectum and pubic symphysis in males: male urethra also for semen transport.
