GROSS ANATOMY OF THE HEART & PATHWAY OF BLOOD THROUGH THE HEART [Fil-in] The circulatory system is divided into a [1 circuit that serves only for gas circuit that supplies blood to the side of the heart. The heart is enclosed in exchange with the air in the lungs and a [2] Cl entire body. The latter is served by the [3] a double-walled membrane called the [4] layer of this membrane forms the outermost layer of the heart wall, the [6) The thick middle, muscular layer of the heart is the [7) the [(81 The [5 - , and the inner lining is The two superior heart chambers are called the 19 Both , separating them. The . Blood flows from here - and the more muscular inferior chambers are the [10] pairs of right and left chambers have a wall, or [11] receiving chamber for all systemic blood is the [12] through the [13) When that chamber contracts, valve [13] chamber exits through the [15] Blood returning from the lungs flows by way of four (16 [17] valve into the left valve into the [14 closes and the blood from this valve into the pulmonary trunk. into the and passes from there through the [18] ventricle. From that point, it is pumped through the [19) 4
