Explanation:

Lungs

are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is to move fresh air into your body while removing waste gases.

Heart

Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly. Your heart is a muscle, and its job is to pump blood throughout your circulatory system.

Arteries 

carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
