Tracheal respiration takes air to

Options

A. Blood
B. Lungs
C. Body cavity
D. Tissues

Answer

To solve the question "Tracheal respiration takes air to," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Tracheal Respiration**:
- Tracheal respiration is a method of gas exchange found in certain organisms, particularly insects. It involves a system of tubes (tracheae) that transport air directly to tissues.

2. **Identify the Components of the Tracheal System**:
- The tracheal system consists of a network of tubes that branch off from the main trachea. These tubes are called tracheoles, which extend throughout the body.

3. **Function of the Tracheal System**:
- The primary function of the tracheal system is to deliver oxygen directly to the tissues of the organism. This is done through diffusion, where oxygen moves from areas of higher concentration (the trachea) to areas of lower concentration (the tissues).

4. **Analyze the Options Given**:
- The options provided are: blood, lungs, body cavity, and tissue.
- Since the tracheal system bypasses the need for lungs and directly delivers oxygen to the tissues, we can eliminate the options of blood and lungs.

5. **Select the Correct Answer**:
- Based on the understanding that tracheal respiration directly supplies oxygen to the tissues, the correct answer is **tissue**.

### Final Answer:
Tracheal respiration takes air to **tissue**.
