Arrange bodily processes into a logical order related to food intake and processing. I. Absorption II. Digestion III. Nutrition (intake) IV. Excretion

Difficulty: Easy

Correct Answer: III, II, I, IV

Explanation:


Introduction / Context:
This question asks for a logical sequence of processes from taking in food to eliminating waste products.


Given Data / Assumptions:

  • Nutrition (III) refers to intake/feeding.
  • Digestion (II) breaks food into absorbable components.
  • Absorption (I) moves digested nutrients into blood/lymph.
  • Excretion (IV) removes metabolic wastes.


Concept / Approach:
Order by physiological dependency: intake → breakdown → uptake → elimination.


Step-by-Step Solution:
Start with III Nutrition (ingestion).Then II Digestion (mechanical/chemical).Next I Absorption (transport into body fluids).Finally IV Excretion (waste removal).


Verification / Alternative check:
Absorption cannot precede digestion in a typical pathway; excretion is terminal.


Why Other Options Are Wrong:
Sequences with absorption before digestion or excretion mid-way violate basic physiology.


Common Pitfalls:
Confusing “nutrition” with “nutrition science”; here it denotes intake.


Final Answer:
III, II, I, IV
