abomasa
n. C2 Proficiency abo·masa
n. a part of the stomach in some animals, like cows, where food is digested. It is the third and final section of their stomach.
n. the third and final compartment of the four-chambered stomach in ruminants, where microbial fermentation of ingested food occurs. Also known as the 'abomasum'.
The cow's abomasa helps break down tough grass.
Veterinarians often check the abomasa to ensure that the cow is digesting its feed properly.
In ruminant physiology, the abomasa serves as the primary site for the absorption of nutrients after the initial microbial breakdown of cellulose in the rumen.
