Consider the order of organs in the digestive system and their positions in the body. why do you think digestion is more efficient if you are sitting up, rather than slumped over or lying down?

The order of the organs is:

Mouth, stomach, small intestines, large intestines

The food is flowing downwards so if you are standing up, it is more easier for the food to travel compared to when you are slumped over or lying down.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
