VII Descriptive TextsThe heart is the most important part of the body. It is the center of life. However, the heart is only as big as a closed hand
The heart is a muscle and it beats about seventy times per minute throughout a person's life
The heart pumps blood from your heart to all parts of your body. The heart is made up of four chambers or small
"rooms." The top chambers are called the right and left auricies and the bottom chambers are the right and left ventricles
When blood enters the heart, it is in dark reddish color because it contains carbon dioxide. The blood enters the night
auricle and then the right ventricle. When the heart contracts, it force's the blood to the lungs where the blood receives
oxygen. It then goes to the left auricle. The heart contracts again, and the blood goes to the left ventricle and is then forced
out into the body. The blood gathers carbon dioxide and returns to the heart, and the process begins again.
