Questions 3 3

In humans, respiration occurs in the following steps. Arrange these steps in the correct order. A. Diffusion of O₂ and CO₂ between blood and tissues B. Diffusion of O₂ and CO₂ across alveolar membrane C. Pulmonary ventilation by which atmospheric air is drawn in and CO₂ rich alveolar air is released out D. Cellular respiration E. Transport of gases by the blood Choose the correct answer from the options given below:

Solution & Explanation

Related Formula

Pulmonary Ventilation arrow Alveolar Diffusion arrow Gas Transport arrow Tissue Diffusion arrow Cellular Respiration

Core Logic

The correct physiological sequence of respiration in humans is:

  • Pulmonary ventilation (breathing) (C)
  • Diffusion of gases (O₂ and CO₂) across alveolar membrane (B)
  • Transport of gases by blood (E)
  • Diffusion of O₂ and CO₂ between blood and tissues (A)
  • Utilisation of O₂ by cells for catabolic reactions / cellular respiration (D)
Step 1: Result

The correct sequential order is C arrow B arrow E arrow A arrow D.

Pattern Recognition

Sees: "respiration steps order". Shortcut: Starts with Pulmonary ventilation (C) and ends with Cellular respiration (D).

Q146 neet_2024_05_may_morning Respiratory Volumes and Capacities
Match List-I with List-II.
List-I (Respiratory Volume)List-II (Capacity in mL)
(A) ERV (Expiratory Reserve Volume)(I) 2500 – 3000 mL
(B) RV (Residual Volume)(II) 500 mL
(C) IRV (Inspiratory Reserve Volume)(III) 1000 – 1100 mL
(D) TV (Tidal Volume)(IV) 1100 – 1200 mL
Choose the correct answer from the options given below:
  • A. A-III, B-I, C-IV, D-II
  • B. A-I, B-III, C-II, D-IV
  • C. A-III, B-IV, C-I, D-II
  • D. A-I, B-II, C-III, D-IV

Solution

Related Formula

aligned Tidal Volume (TV) &= 500 mL Expiratory Reserve Volume (ERV) &= 1000 - 1100 mL Residual Volume (RV) &= 1100 - 1200 mL Inspiratory Reserve Volume (IRV) &= 2500 - 3000 mL aligned

Core Logic

Matching each respiratory volume with its standard physiological value:

  • (A) ERV arrow 1000 – 1100 mL (III)
  • (B) RV arrow 1100 – 1200 mL (IV)
  • (C) IRV arrow 2500 – 3000 mL (I)
  • (D) TV arrow 500 mL (II)
Step 1: Result

The correct option is A-III, B-IV, C-I, D-II.

Pattern Recognition

Sees: "Tidal Volume 500 mL". Shortcut: TV = 500 mL (D-II), IRV = largest volume 2500–3000 mL (C-I).

Q177 neet_2024_05_may_morning Respiratory Organs in Animal Groups
Match List I with List II:
List IList II
(A) Molluscs(I) Pulmonary respiration only
(B) Reptiles(II) Branchial respiration
(C) Adult amphibians(III) Cellular respiration
(D) Amoeba(IV) Pulmonary and cutaneous respiration
Choose the correct answer from the options given below:
  • A. A-III, B-II, C-I, D-IV
  • B. A-II, B-I, C-IV, D-III
  • C. A-II, B-I, C-III, D-IV
  • D. A-I, B-II, C-IV, D-III

Solution

Related Formula

aligned Molluscs &arrow Feather-like gills (Branchial respiration) Reptiles &arrow Lungs (Pulmonary respiration only) Adult Amphibians &arrow Lungs and moist skin (Pulmonary and Cutaneous) Amoeba &arrow Cellular respiration / Simple diffusion aligned

Core Logic

Matching organisms with their respiratory modes:

  • (A) Molluscs arrow Branchial respiration via feather-like gills in mantle cavity (II)
  • (B) Reptiles arrow Pulmonary respiration only via lungs (I)
  • (C) Adult amphibians arrow Pulmonary and cutaneous respiration via lungs and moist skin (IV)
  • (D) Amoeba arrow Cellular respiration (III)
Step 1: Result

The correct combination is A-II, B-I, C-IV, D-III.

Pattern Recognition

Sees: "Molluscs Reptiles Adult amphibians Amoeba". Shortcut: Adult amphibians = Pulmonary and cutaneous (C-IV); Reptiles = Pulmonary only (B-I).
