Samara is an astronaut in deep space away from gravity. how could her urine move away from the kidneys and to the bladder in such a situation?

Sagot :

Peristalsis can make her urine move away from the kidneys and to the bladder in such a situation.

Muscles contract and relax in a radially symmetrical pattern during peristalsis, which travels anterogradely down a tube like a wave. It is what carries food and liquids through each step of digestion. We would be unable to feed or eliminate without peristalsis. Peristalsis's gradual but constant movement is crucial for the health of the digestive system. It allows your body enough time to digest food and simultaneously absorb nutrients.

The pelvic pressure rises when the urine is gathered in the renal pelvis, starting a peristaltic contraction that travels down the ureter to the bladder. With pressure ranging from 50 to 100 mm Hg, the peristaltic wave might push urine against an obstruction.

Peristalsis can only move the pee from the kidney into the bladder at relatively modest mean rates of urine flow, according to a one-dimensional, lubrication-theory analysis. In these conditions, isolated boluses of urine are steadily pushed (assumed uniform) down the ureter by the contraction waves.
