What are my objectives while studying this topic?

The heart is the central organ within the circulatory system. You will study the structure of the heart and the specialized cells that make up the tissues forming the heart. This will help you understand the function of the heart within the cardiac cycle. You will also study the composition of the blood and how its content is maintained in the circulatory system.

Why is this important?

Fitness and healthcare professionals measure and monitor heart function and the control of the blood flowing to and from the rest of the body by taking physiological measurements. These measurements assist professionals improve the well being and performance of an individual’s circulatory system as well as diagnosing cardiovascular diseases.
