Animals
Many other animals, including mammals, also have four-chambered hearts, and have a left atrium. The function in these animals is similar. Some animals (amphibians, reptiles) have a three-chambered heart, in which the blood from each atrium is mixed in the single ventricle before being pumped to the aorta. In these animals, the left atrium still serves the purpose of collecting blood from pulmonary veins.

Famous quotes containing the word animals:
“The alcoholic trance is not just a haze, as though the eyes were also unshaven. It is not a mere buzzing in the ears, a dizziness or disturbance of balance. One arrives in the garden again, at nursery time, when the gentle animals are fed and in all the world there are only toys.”
—William Gass (b. 1924)
