Root Explanation

Abomasum is derived from the Latin "abomasum" (meaning the fourth stomach of ruminants). The word itself is a combination of "ab-" (meaning away) and "omasum" (meaning the third stomach). The abomasum is the stomach that follows the omasum in the digestive system of certain animals, particularly ruminants like cows and sheep.

Memory Tip

Think of the 'fourth stomach' in ruminants, where 'ab-' suggests it is 'away' from the previous stomach ('omasum'). This helps you remember that the abomasum is the stomach that comes after the omasum.
