"sends oxygen-poor blood to the lungs to pick up oxygen and unload carbon dioxide" pulmonary circuit "sends oxygen-rich blood and nutrients to all body cells and removes wastes." systemic circuit A hollow muscular organ that pumps the blood through the circulatory system by rhythmic contraction and dilation. In vertebrates there may be up to four chambers (as in humans), with two atria and two ventricles. heart A cover-ing that encloses the heart and the proximal ends of the large blood v...
