#digestion and absorption MCQ

Digestive System

Most nutrients absorbed from intestine reach liver via:

The correct answer is C: Hepatic portal vein. In Digestive System, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, Hepatic portal vein is the option that correctly names the structure, process, or principle asked for in Digestive System. That is why Hepatic portal vein is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Digestive System

Segmentation movements in small intestine mainly help in:

Answer: B) Mixing chyme with enzymes. For Digestive System, once you lock onto the key mechanism or definition, Mixing chyme with enzymes is the clear fit. If you restate the concept in your own words, the functional job described in the stem is exactly what Mixing chyme with enzymes does in Digestive System. So Mixing chyme with enzymes is the clean, accurate selection. If a similar stem appears later, start from the same core fact and you will land on the same kind of answer. In class notes, highlight this same phrase next to the related diagram so the wording and the picture reinforce each other.

Lacteals present in villi mainly absorb:

Pick C: Fatty acids. Thinking about Digestive System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: the functional job described in the stem is exactly what Fatty acids does in Digestive System. Hence Fatty acids is correct. Treat this as a building block for the rest of Digestive System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Fatty acids.

Digestive System

Finger-like projections that increase absorptive surface are called:

Pick B: Villi. Thinking about Digestive System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: this is mainly a definition check, and Villi is the standard term or meaning used in Digestive System. Hence Villi is correct. Treat this as a building block for the rest of Digestive System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Villi.
