Assertion (A): Muscles of stomach wall possess thick layers of muscle...
Assertion and Reasoning:

Assertion (A): Muscles of stomach wall possess thick layers of muscle fibers.

Reason (R): These muscles help in mixing the food with the enzymes present in the alimentary canal.

Explanation:

The stomach is a muscular sac that mixes and grinds food into a liquid-like state before it passes into the small intestine. The muscular walls of the stomach contain three layers of smooth muscle fibers: the longitudinal layer, the circular layer, and the oblique layer.

The thick layers of muscle fibers in the stomach wall play a crucial role in the mechanical digestion of food. The muscles contract and relax in a coordinated manner, churning the food and mixing it with the digestive juices and enzymes present in the stomach.

The circular layer of muscles forms a sphincter that controls the release of food from the stomach into the small intestine. The oblique layer of muscles provides additional mixing, while the longitudinal layer helps to move the food through the stomach.

Therefore, both the assertion and the reasoning are correct, and the reasoning correctly explains the assertion.

Option (A) is the correct answer.

Conclusion:

The muscles of the stomach wall possess thick layers of muscle fibers that help in mixing the food with the enzymes present in the alimentary canal. The assertion and reasoning are correct, and the reasoning correctly explains the assertion.
