    52 CHAPTER XIII. THE CmCULATOIlY ORGANS. 187. The blood is distributed to every part of the system There is no part so minute, tliat it does not receive this circu- lating fluid. This distribution is efTected by the agency of the Heart, Ar'te-ries, Veins, and Cap'il-la-ries. ANATOMY OF THE CIRCULATORY ORGANS. 188. The HEART is situated in the chest, between the lungs. (Fig. 53.) It is a double organ, or has two sides, called right and left, which are separated by a muscular sep'tum, or partition. 189. Each side of the heart has two cavities. The upper cavity is called the au'ri-cle, (deaf ear.) The lower cavity is called the ven'tri-cle. These cavities are separated from each other by folds of membrane, called valves. (Fig. 38.) 190. Between the auricle and ventricle of the right side of the heart, there are three valves, called tri-cus'pid. Between the auricle and ventricle of the left side of the heart, there are two valves, called mi'tral. Observation. To obtain a clear idea of the heart and its valves, it is recommended to examine this part of an ox or calf. In order that each ventricle be opened without muti- 187.
