Detail of the helmet's feedport.
Some contingency plans call for the astronauts to be in their pressurized suit
for an extended period of time (e.g., if the command module were to lose
pressurization). In such cases, the feedport's
cover would be removed, exposing an opening
through which food and water could be
passed without losing suit pressurization (see the Apollo Lunar Surface
Journal for additional information).
At the other end of the digestive system, the astronaut can wear a urine collection and
transfer assembly, which attaches to the suit's urine
transfer connector (underneath a flap on
the upper right thigh) so that the urine can be drained from
