Q1 · Gastric Acid Secretion
NEET PGEasyExplanation
Parietal, or oxyntic, cells secrete hydrochloric acid and intrinsic factor. Chief cells secrete pepsinogen and G cells secrete gastrin. Proton pump inhibitors block the parietal cell H+/K+ ATPase.
Q2 · Gastrointestinal Hormones
NEET PGMediumExplanation
Secretin, released from duodenal S cells in response to acid, stimulates pancreatic and biliary bicarbonate secretion to neutralise chyme. Cholecystokinin stimulates enzyme secretion and gallbladder contraction.
Q3 · Intrinsic Factor
EasyExplanation
Parietal cells secrete intrinsic factor, which binds vitamin B12 for absorption in the terminal ileum. Loss of intrinsic factor, as in pernicious anaemia, causes B12 deficiency.
Q4 · Bile Salts
MediumExplanation
Bile salts emulsify dietary fats into micelles, increasing the surface area for pancreatic lipase and aiding absorption of fats and fat-soluble vitamins. They are recycled via the enterohepatic circulation.
Gastrointestinal sits within Physiology, which carries the same syllabus in both exams. This set runs to 4 questions, each tagged Easy, Medium or Hard, and 2 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Gastrointestinal marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Physiology examiners keep returning to.
FAQ
Yes. Every question and explanation in this Gastrointestinal set is free and open — no login, no form and no payment. The explanation appears the moment you answer.
Gastrointestinal sits within Physiology, which appears in the same form in both syllabuses. System-wise physiology with the mechanisms examiners test most: cardiac and respiratory regulation, renal handling, endocrine axes and nerve conduction.
