where does blood go after the pulmonary artery
Pulmonary circulation From the right ventricle, blood is pumped through the semilunar pulmonary valve into the left and right main pulmonary arteries (one for each lung), which branch into smaller pulmonary arteries that spread throughout the lungs.
Small intestine Food from the stomach is allowed into the duodenum through the pylorus by a muscle called the pyloric sphincter.
Limit of a function (the Dirichlet function) has no limit at any x-coordinate.
