C) Right atrium
D) Right ventricle
Solution
Solution Steps
Step 1: Understanding the circulatory system
The heart has four chambers: two atria and two ventricles. The right atrium receives deoxygenated blood from the body and sends it to the right ventricle. The right ventricle pumps this blood to the lungs to pick up oxygen. The left atrium receives oxygenated blood from the lungs and sends it to the left ventricle. The left ventricle pumps this oxygenated blood to the rest of the body.
Step 2: Identifying the chamber that pumps oxygenated blood
The question asks which chamber pumps oxygenated blood _to the body_. We know that the left side of the heart deals with oxygenated blood. The left atrium receives oxygenated blood, while the left ventricle pumps the oxygenated blood out to the body.
Step 3: Choosing the correct answer
The left ventricle is the chamber that pumps oxygenated blood to the body. Thus, the correct answer is B) Left ventricle.
