The Mammalian Heart Analysis Questions 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

2B Cardiovascular Diseases The heart is an essential organ in the cardiovascular system responsible for pumping oxygen and nutrition filled blood to all parts of the human body. It is composed of four chambers; two upper chambers called the right and left atrium‚ and two lower chambers called the right and left ventricle. A structure called the septum is what divides the heart into right and left halves. Four heart valves keep the flow of blood in one direction. At rest‚ the heart usually beats 60
