Which gland secretes chemical by simple diffusion :-

Options

A. Apocrine gland
B. Holocrine gland
C. Merocrine gland
D. Oil gland

Answer

To answer the question "Which gland secretes chemicals by simple diffusion?", we can follow these steps:

### Step 1: Understand the Types of Glands
There are different types of glands in the body that secrete substances in various ways. The main types mentioned are:
- Apocrine glands
- Holocrine glands
- Mirocrine glands
- Oil glands

### Step 2: Analyze Each Gland Type
- **Apocrine Glands**: These glands secrete substances by rupturing their plasma membrane. An example is the mammary gland.
- **Holocrine Glands**: Similar to apocrine glands, these also release substances by rupturing the plasma membrane. A common example is the sebaceous (oil) gland.
- **Mirocrine Glands**: These glands secrete substances through simple diffusion, which means they do not rupture. Instead, they allow the movement of chemicals from areas of higher concentration to lower concentration. A common example is the sudoriferous (sweat) gland.
- **Oil Glands**: These are a type of holocrine gland and secrete oil by rupturing.

### Step 3: Identify the Correct Gland
From the analysis:
- The **mirocrine gland** is the one that secretes chemicals by simple diffusion.

### Conclusion
The correct answer to the question is the **mirocrine gland**.
