Two large veins empty the impureblood of the body into the right auricle. The right auricle con-tracting forces the blood through the opening in the partitioninto the right ventricle; the valve preventing return. The rightventricle contracts and forces the blood into the pulmonary artery,which branches a few inches above the heart, connecting with theright and left lungs. These are again divided into other smallarteries which flow into what is called the capillary net-work,which is situated around the air-cells of the lungs, where theblood gives up its carbonic acid gas, and takes in oxygen fromthe air, which changes the color from a dark purplish red to abright red. Here is emphasized the necessity of well ventilatedquarters, in order that the carbonic acid gas may be carried offand the oxygen supplied. The pulmonary veins now return theblood to the left auricle, and the contraction of the auricle sendsthe blood through the opening into the left ventricle, which. a o ko « 0 r-^ cv r^ <*• »o^ ^ tv 00^ ANATOMY OF THE HORSE 39 opening is guarded to prevent a return, while the left ventriclecontracts and forces the blood into the aorta or large artery of thebody, which passes above the heart two or three inches, wherethe artery branching, sends one forward to supply the parts ofthe body in front of the heart, and another backward along thespinal bones, to supply the body behind the organ. The branch that goes forward soon divides, sending offbranches to supply the shoulder? and forelegs, while two otherbranches, called the carotid arteries, pass along each side of theneck under the jugular veins, giving off branches to supply themuscles and parts of the neck. Just below the butt ofthe earsthese divide again each into three large branches, which supplythe brain and other parts of the head. The branch of the aortathat turns backward f
