You should be asking them if it is an appropriate show for you to watch. If I were a mother, I would not let my 13 year old watch it. There is a lot of adult content that is not suitable for someone your age. I'm an adult, and I don't even like the show. 1-0-0-1 Â· 5 years ago.
The heart and lungs are very closely connected. Not only do they fit closely together in the chest, but they also work together to make sure that every part of your body gets the oxygen it needs. In our discussion of how the heart works, we said that blood is pumped from the right side of your heart to your lungs. Just like the air you inhale moves through passageways, the blood that flows through your lungs moves through a set of branching pipes called pulmonary vessels.
Lungs are composed of many small chambers or air sacs surrounded by blood capillaries. Thus, they work with the circulatory system, which transports oxygen from inhaled air to all tissues of the body and also transports carbon dioxide from body cells to the lungs to be exhaled. After air enters the lungs, oxygen moves into the bloodstream through the walls of these capillaries.
