1. Understanding the Heart
By: Professor Wallice

2. The Heart
Function: a pump to send oxygen-
rich blood, which contains oxygen
and nutrients that every cell in
your body need to survive, to all
parts of your body.

3. Fish
Fish have a two-chambered heart that
pumps the blood to the gills and from
there it goes on to the rest of the body.

4. Amphibians
Have a three-chambered heart and a double
circulatory system which is used, but the heart is
not always completely separated into two pumps

5. Human
Each time the heart contracts it does with all its
force.
In skeletal muscles, the principle of gradation is
present.
