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.

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.
