Correct Answer: 1-d, 2-c, 3-b, 4-a
Correct matching of ruminant stomach chambers and their nicknames:
- 1. Rumen → d) Paunch: Largest compartment (~80% of stomach volume). Primary fermentation vat. Called 'Paunch' (informal for belly/stomach).
- 2. Reticulum → c) Honey comb & Tool box: Smallest compartment with characteristic honeycomb mucosal pattern. Also called 'Hardware stomach' — where swallowed metal objects settle (causing traumatic reticuloperitonitis). Regurgitation initiates here.
- 3. Abomasum → b) Rennet bag: The 'true stomach' with gastric glands secreting HCl and pepsinogen. Called 'Rennet bag' because it contains rennin (chymosin) — the commercial enzyme used in cheese-making comes from calf abomasum. Pepsinogen and HCl are secreted in ruminants by abomasum.
- 4. Omasum → a) Many-plies: Has many leaf-like laminae (folds), resembling pages of a book (also called 'Book stomach' or 'Bible'). Absent in pseudo-ruminants. Functions in water absorption and particle size reduction.
