The draw tube in a compound microscope allows the user to adjust the distance between the eyepiece and the objective lens to achieve proper focus. This adjustment helps to ensure that the specimen being observed is in sharp focus for clear viewing.
The tube that leads from the middle ear to the throat is called the Eustachian tube. Its function is to equalize air pressure between the middle ear and the atmosphere, which helps protect the ear from damage and allows for proper hearing. It also helps drain fluid from the middle ear to prevent infections.

The limb on a microscope holds the body tube and nosepiece in place. It provides stability and support for adjusting the height of the body tube to focus on the specimen.
The Eustachian tube connects the middle ear to the throat. Its main function is to help equalize air pressure on both sides of the eardrum, which is important for proper hearing and balance. If the Eustachian tube is blocked or dysfunctional, it can lead to ear pain and hearing problems.
