If there is no gravity in space then how do astronauts attend their natural calls?

  Certainly not a mechanical engineering question. Moved to chit chat section.
  
  ☕ Interesting.

  Thanks Big K. I was confused where to post it..
  Any ways do you have the answer to it??

  I am not sure but may be they have a tube to their front and back ends which takes all their waste into a container.😛

  Curiously enough this is a mech engg question. Decades back the journal 'New Scientist' carried an article on this titled,'The Day the Shit did not hit the fan'. While gravity is absent, air flow and vacuum can be created. The effluent is carried by an air stream to a highspeed fan that disintegrated it and sent it onward for the waste handling system. In one of the early missions, the fan failed creating a crisis of the sort raised by zaki_whiz03.

  How and what do they eat...? they are sealed from top to bottom 😐

  Okay, mea culpa. 😕 I thought this is a general interest based question. But we'll keep it in the chit-chat section.

  A. There is a nice space shuttle web page at: #-Link-Snipped-# Digging in there I found a Q&A Web page. Here's what it says: #-Link-Snipped-#
  6. How do you take a bath, brush your teeth, and go to the bathroom in space?
  We do not have a bath or shower on the Shuttle, so we just wash off with wet washcloths, using soaps that you don't have to rinse off. When we brush our teeth, we can either swallow the toothpaste or spit it into a washcloth. Designing a toilet for zero-gravityis tougher. We use air flow to make the urine or feces go where we want, since gravity will not do it for us. You have to be more careful and think about what you are doing with the toilet in the Shuttle.
  B. Another colleague pointed out that Johnson Space Center is the home of the astronauts, and they have some web pages dealing with this issue too. (We really know little more than you do about the astronaut program -- but they do.)
