The path a blood cell takes throughout the circulatory system starting at the right atrium and ending at the capillaries is called a ventricle.

Circulatory system
Circulatory system
The atrium is part of the heart, which is a part of the circulatory system.
Right atrium > right ventricle > pulmonary artery > lung > pulmonary vein > left atrium > left ventricle > aorta > arteries > arterioles > capillaries > venules > veins > vena cava > right atrium (again)
Circulatory system
Starting from the right atrium, blood flows into the right ventricle then into the pulmonary arteries. The blood branches throughout the pulmonary trunk and down to the level of the pulmonary capillaries. At this level carbon dioxide dissolves out of the blood and the erythrocytes (red blood cells) pick up oxygen. The blood is collected in the pulmonary veins and taken back to the left atrium for distribution throughout the body.
right atrium
The circulatory system does create, essentially, one or two large loops in the body. Blood moves from the left ventricle to the systemic arteries, then capillaries, then veins of the systemic circulation. Blood returns from the systemic circulation to the right atrium, then right ventricle, then to the pulmonary artery. It goes to the lungs and returns to the left atrium via the pulmonary veins.
