Welcome to this course on circulation and the heart. This course is lively and the need to write it is in my very blood. See what I did there? Read on to learn all about the engine that powers your body.
Your circulatory system comprises your heart, blood vessels and the blood itself. Arteries, veins and capillaries transfer blood around the body and with it the oxygen and nutrients we need to survive.
The heart is the most amazing piece of biological engineering. It beats 24/7 from before you are even born until the moment you die. These slides explain the functions and the working parts of the heart.
The heart is divided into four chambers. These are the atria and the ventricles. From this powerful pump, blood flows to where it is needed in your body, all day and all night.
This is a timed quiz. You will have 30 seconds per question. Test your knowledge and see what you have learned about the heart and the circulatory system in this course.
