View Heart Diagram Pulmonary Artery Background. The pulmonary artery, or pulmonary trunk, originates from the bottom of the right ventricle of the heart. The pulmonary artery, being an exception, carries deoxygenated blood to the lungs for purification.
In this article we will consider the structure and anatomical relationships of the aorta, pulmonary arteries and veins, and the superior and inferior vena cavae. The veins carry impure blood from different parts of the body to the heart for oxygenation. Contraction of the heart pumps blood through the heart and out into arteries.
The oxygen present in the tiny air sacs.
In this image, you will find superior vena cava, right pulmonary artery, right pulmonary veins, right atrium, inferior vena cava, coronary sinus, right coronary artery, coronary sulcus, posterior interventricular artery in it. For blood to pass through the heart from the left atrium to the left ventricle, it must first pass through a) an artery c) a vein b) a valve d) a capillary Small branches dive into the heart muscle to bring it blood. The pulmonary artery, being an exception, carries deoxygenated blood to the lungs for purification.
