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.
two types of balance are there,STATIC balance and DYNAMIC balance.dynamic balance,that is during movement,is maintained by the SPECIAL HAIR CELLS in the 3 semicircular canals â¦present in internal ear[or LABYRINTH] WHILE STATIC balance is maintained by the SACCULUS $ UTRICULUS,, also the part of labyrinth.
