Best Answer: 1. The blood in the left atrium is oxygenated while the blood in the right atrium is deoxygenated.
2. The blood in the left atrium is rich in oxygen while the blood in the right atrium is rich in carbon dioxide.
3. The left atrium recieves the blood returning to the heart from the superior and inferior vena cava, which comes the upper and lower body. The left atrium recieves the blood returning to the heart from the pulmonary vein, which comes from the lungs.
4. The walls of the left atrium are thicker than those of the right atrium because higher pressure is generated in the left side of the heart in order for oxygenated blood to be pumped to the rest of the body. The walls of the right atrium are thinner.
5. The left atrium is located on the left side of the heart, while the right atrium is located on the right side of the heart. They are separated by a muscular wall known as the median septum.
6. The left atrium has a bicuspid valve that opens it to the left ventricle while the right atrium has a tricuspid valve which opens it to the right ventricle.
7. The left atrium connects to the left ventricle while the right atrium connects to the right ventricle.
