Phylum-wise features and examples. Tables beat paragraphs for this one.

Structural Organisation in Animals

Only the frog survives the rationalisation. Animal tissues carry the questions.

Not in the NEET syllabus

Removed from the rationalised NCERT and the NMC syllabus. Digestion and Absorption is gone entirely, so human physiology now starts at breathing.

Digestion and Absorption (whole chapter)
Nutritional and digestive disorders — PEM, indigestion, jaundice
Earthworm and cockroach accounts in Structural Organisation
Reflex action and reflex arc
Sense organs — structure of the eye and ear
Population and ecological adaptations as a Class 11 topic
