(Mass #) = (Atomic #) + (Neutron #)
: . (Neutron #) = (Mass #) - (Atomic #)
= 162 - 41
= 121

Specializations of the small intestine are related to surface absorption it doesn't include Peyer's patches.
<h3>What is the small intestine?</h3>
It lies between the stomach and the large intestine and is by far the longest part of the digestive tract.
