Explanation: 

Detailed explanation-1: -The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.

Detailed explanation-2: -The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.

Detailed explanation-3: -Within your blood, red blood cells have a specialized task. They pick up oxygen in your lungs and carry it to your body’s tissues and organs. Your blood then transports carbon dioxide back to the lungs where you can breathe it out.

Detailed explanation-4: -The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide.
