Consider the following statements each with two blanks.
(i) Actually, only about `overset((1))"_____"` mL of air enters the lungs alveoli for the exchange of gases. The remaining fills the respiratory passage and is termed `overset((2))"_____"`.
(ii) The amount of air which one can inhale with maximum effort and also exhale with maximum effort is termed as `overset((3))"_____"`. It is about `overset((4))"_____"` in normal adult person.
(iii) During normal quiet breathing, on an average, approximately `overset((5))"_____"` mL of air is inspired or expired by adult human male in each breath. It is termed as `overset((6))"_____"` volume.
Which of the following options gives the correct fill ups for the respective blanks numbers from (1) to (6) in the above statement ?

Options

A. `(3)`-vital capacity, `(4)-4000` mL, `(5)-500, (6)-`tidal
B. `(1)-100`, `(2)`-residual volume, `(3)-`functional residual capacity, `(4)-3000 mL`
C. `(1)-350`, `(2)`-dead space air, `(5)-1000, (6)`-inspiratory reserve
D. `(1)-350`, `(2)`-residual volume, `(3)-`vital capacity `(4)-4000 mL`

Explanation

To solve the question, we need to fill in the blanks in the statements provided. Let's break it down step by step:

### Step 1: Analyzing the First Statement
The first statement mentions the volume of air that enters the lungs for gas exchange and the remaining air that fills the respiratory passages.

- **Fill in the first blank (1)**: The volume of air that enters the alveoli for gas exchange is approximately **350 mL**.
- **Fill in the second blank (2)**: The remaining air that fills the respiratory passages is termed **dead space volume** (or simply **dead air**).

### Step 2: Analyzing the Second Statement
The second statement refers to the amount of air that can be inhaled and exhaled with maximum effort.

- **Fill in the third blank (3)**: This amount is termed **vital capacity**.
- **Fill in the fourth blank (4)**: The vital capacity for a normal adult person is about **4000 mL**.

### Step 3: Analyzing the Third Statement
The third statement discusses the average amount of air inspired or expired during normal quiet breathing.

- **Fill in the fifth blank (5)**: The average volume of air inspired or expired in each breath is approximately **500 mL**.
- **Fill in the sixth blank (6)**: This volume is termed **tidal volume**.

### Final Answers
Now, let's summarize the filled blanks:
1. **(1)** 350 mL
2. **(2)** Dead space volume
3. **(3)** Vital capacity
4. **(4)** 4000 mL
5. **(5)** 500 mL
6. **(6)** Tidal volume

### Complete Statement
- (i) Actually, only about **350 mL** of air enters the lungs alveoli for the exchange of gases. The remaining fills the respiratory passage and is termed **dead space volume**.
- (ii) The amount of air which one can inhale with maximum effort and also exhale with maximum effort is termed as **vital capacity**. It is about **4000 mL** in a normal adult person.
- (iii) During normal quiet breathing, on average, approximately **500 mL** of air is inspired or expired by an adult human male in each breath. It is termed as **tidal volume**.
