Hello, I am Mr. Smith, but you can tell me Smith, today I come here to speak to you about the heart
Welcome Smith, I am excited to be in this class, please start!
The heart is the organ, or body part, that pumps blood through the body. It is the main organ of the cardiovascular system. The cardiovascular system carries substances to and from all parts of the body in the blood.
It's like the digestive system, also this pass substances on the body
Like Mike said, I think that this have also some things that looks like the digestive system
In that side, is related with that system, but, also have diferences
In this case, the heart pass blood, not other substance from the digestive system
