Cardio Vascular System

This system works by distributing our blood throughout the body. The main organ of this system is the heart because without the heart, nothing will pump the blood and spread it throughout our body. In this lesson, I learned about the blood ,the blood vessels, and the different cells. I also learned about the cardiac cycle in which the heart pumps the blood so it can go to the different parts of the body. . .

In reporting this system you must show videos that is appropriate for your report. Like, show the video on how the cardiac cycle work. . . ..THATS ALL FOLKS!!! ..hahahaa
