Answer

To solve the question "The _____ is made up of pinna, the ear canal and the eardrum," we need to identify which part of the ear is being described.

### Step-by-Step Solution:

1. **Identify the Components**: The question mentions three specific parts: the pinna, the ear canal, and the eardrum.

2. **Understand the Function**: The pinna is the visible part of the ear that helps to collect sound waves. The ear canal is the passage that leads sound waves to the eardrum, which vibrates in response to sound.

3. **Categorize the Parts**:
- The **pinna** is also known as the auricle and is the outermost part of the ear.
- The **ear canal** is the tube that connects the outer ear to the eardrum.
- The **eardrum** (tympanic membrane) is the boundary between the outer ear and the middle ear.

4. **Determine the Ear Section**:
- The outer ear consists of the pinna, ear canal, and eardrum.
- The middle ear contains the ossicles (tiny bones) and is located behind the eardrum.
- The inner ear includes structures like the cochlea and vestibular system.

5. **Select the Correct Answer**: Based on the components listed, the correct answer to fill in the blank is "outer ear."

### Final Answer:
The **outer ear** is made up of pinna, the ear canal, and the eardrum.
