how is the blood in the pulmonary artery different from blood in other arteries
Pulmonary artery A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the heart to the lungs. The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles which lead to the capillaries that surround the pulmonary alveoli.
Inferior vena cava The corresponding vein that carries deoxygenated blood from the upper half of the body is the superior vena cava.
Ventricle (heart) In a four-chambered heart, such as that in humans, there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta.
Ä Ä (lower case ä) is a character that represents either a letter from several extended Latin alphabets, or the letter A with an umlaut mark or diaeresis.
