Human nutrition — IGCSE Sciences - Co-Ordinated (0973) questions by topic
Human nutrition questions label parts of the digestive system on a diagram, name a function of bile, identify which organ neutralises gastric juices, and name the outer and central layers of a human tooth, worth from 1 to 13 marks in this IGCSE Co-ordinated Sciences set.
Identify, state and calculate lead the command words, with describe and complete also common: identify a labelled organ by matching its function precisely, not a nearby structure. 21 real questions from 2023 to 2025 papers sit here. Submitting each answer for instant marking flags a digestive organ confused with a neighbouring one before the same mix-up recurs.
