The answers to the given questions are as follows:

1. The statement(A)- It is also called the voice box does not describe the trachea.

The larynx present in the neck area just above the trachea is also called the voice box.

This creates an enlarged chest cavity that helps in taking in air into the lungs.

The food that we take in gets digested in our body. All essential nutrients are transported to various parts of the body( to the cells) via blood. Blood also carries the oxygen that the cells require.

Arteries carry oxygenated blood from the heart to all the parts of the body.
