1. The job performed by the atria is collecting blood, while the job performed by the ventricles is pumping blood. Since the atria are thin-walled, they must function similar to thin bags that collect the blood. The ventricles have thick walls, which allow them to contract strongly to be able to pump blood to the rest of the body. 2. The deoxygenated blood must be pumped to the lungs, where it becomes oxygenated prior to be being pumped back to the rest of the body to deliver oxygen to organs. 3. It is necessary to pump blood from the lungs to the body because the body needs oxygen.
Red blood cells must carry oxygen from the lungs to the rest of the body because the body cells within organs need oxygen to function. 4. The right side of the heart pumps the blood to the lungs. The aorta pumps blood to the entire rest of the body. The left ventricle of the heart collects blood and pumps blood throughout the body via the aorta. Based on my observations in Data Table 1, the right ventricle is thinner than the left because it only has to pump blood to the lungs, while the left ventricle has to pump blood to the entire rest of the body.
5. According to Table 2, arteries have thicker walls because the arteries contain muscles along the walls that help move the blood. The Mammalian Heart Analysis Questions 1.
