Scope and sources

Cambridge IGCSE Biology 0610 · 2026–2028 v3 · Original learning materials.

Absorption (7.5.1–7.5.5): the small intestine as the region where nutrients are absorbed, where water is absorbed (small intestine and colon), and, for the Supplement, villi and microvilli, the structure of a villus and the roles of its capillaries and lacteal. Digestion itself is in the physical and chemical digestion modules; assimilation and the hepatic portal vein are not covered.

Apparatus, amounts and times in the experiment are illustrative. Real practical work follows a teacher-approved safety method.
