The atria receive blood from various parts of the body and pass it into the ventricles. The ventricles, in turn, pump blood to the lungs and to the remainder of the body. The right atrium, or right superior portion of the heart, is a thin-walled chamber receiving blood from all tissues except the lungs.
The Vestibule and Semicircular Canals. While the cochlea is involved in hearing, the other two parts of the inner ear's bony labyrinth, the vestibule and semicircular canals, are involved in keeping you upright-your sense of balance, that is. The vestibule detects changes in linear acceleration-that is to say, movement in one direction.
They receive messages from the ears so that you can recognise sound and messages. This part of the brain also recognises speech and is how you understand what someone says to you. It also helps your sense of smell. Your short term memory is also kept here. Cerebellum. The cerebellum sits at the back of the brain and controls your sense of balance.
