abomasum
n. C2 Proficiency abo·ma·sum
n. the fourth and final stomach of a cow or other ruminant animal. It is where the food is digested and the nutrients are absorbed.
n. the fourth and final compartment of the stomach in ruminant mammals, functioning as the site of enzymatic digestion and nutrient absorption.
The cow's abomasum is where the food is finally digested.
After the initial fermentation in the rumen, the food moves to the abomasum for further chemical breakdown.
The abomasum contains high concentrations of hydrochloric acid and enzymes that allow the animal to extract maximum nutritional value from its fibrous diet.
From New Latin abomāsum, from ab- (“away from”) + omāsum (“tripe of a bullock”).
