AP BIOLOGY

Detailed explanation-1: -The abomasum is lined with glands to release hydrochloric acid and digestive enzymes needed to break down food. It is very similar to the nonruminant stomach.

Detailed explanation-2: -The abomasum produces hydrochloric acid and digestive enzymes, such as pepsin (breaks down proteins), and receives digestive enzymes secreted from the pancreas, such as pancreatic lipase (breaks down fats). These secretions help prepare proteins for absorption in the intestines.

Detailed explanation-3: -ABOMASUM: The final compartment of the stomach is the abomasum. This compartment is similar to our stomachs and has a low pH and enzymes to digest the proteins in the feed.

Detailed explanation-4: -The abomasum, also known as the maw, rennet-bag, or reed tripe, is the fourth and final stomach compartment in ruminants.

Detailed explanation-5: -Option B: Abomasum is the only chamber that contains different enzymes, their glands, acids required for digestion in the cow, Hence it is known as the True stomach, Therefore, this is the correct option.
