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:
“Lost at night in an immense forest, I only have a small light to guide me. A man appears who tells me: “My friend, blow out your candle in order to find your way.” This man is a theologian.
The sea, fluid garden filled with animals and plants.”
—Alfred Döblin (1878–1957)
“If everything is perfect, language is useless. This is true for animals. If animals don’t speak, it’s because everything’s perfect for them. If one day they start to speak, it will be because the world has lost a certain sort of perfection.”
—Jean Baudrillard (b. 1929)
“We know what the animals do, what are the needs of the beaver, the bear, the salmon, and other creatures, because long ago men married them and acquired this knowledge from their animal wives. Today the priests say we lie, but we know better.”
—native American belief, quoted by D. Jenness in “The Carrier Indians of the Bulkley River,” Bulletin no. 133, Bureau of American Ethnology (1943)
