7 Pulmonary Circulation
Pulmonary circulation adds _____________ and removes _____________ from the blood. Blood returning to the heart from the body tissues is low in oxygen and high in carbon dioxide. This blood enters the _____________ and flows into the _____________. This chamber of the heart pumps it through the _____________ arteries to the lungs. These are the only _____________ that carry _____________ blood. All other _____________ carry _____________ blood. As the blood travels through the capillaries in the lungs, it gains _____________ and gets rid of _____________. The pulmonary capillaries merge into pulmonary veins. These veins carry the _____________ blood to the _____________ of the heart. The _______________ are the only _____________ that carry oxygen-rich blood. All other _____________ carry oxygen-poor blood. oxygen carbon dioxide right atrium right ventricle pulmonary arteries oxygen-poor arteries oxygen-rich oxygen carbon dioxide oxygen-rich left atrium pulmonary veins veins veins

8 Systemic Circulation From the _____________ the blood enters the _____________. Systemic circulation begins in the _____________ of the heart. From here the blood is pumped into the _____________. It branches forming arteries that serve all parts of the body. The arteries divide into arterioles an finally into _____________. These tiny blood vessels are the sites for _____________ and _____________ exchange between the blood and body cells. Capillaries merge to form veins. These veins finally return the blood to the heart. The largest veins of the body are: the _________________ which returns blood from the upper parts of the body, and ________________ which returns blood from the lower parts of the body. left atrium left ventricle left ventricle aorta capillaries oxygen carbon dioxide superior vena cava inferior vena cava
