Circulatory system

This video tutorial by Matt from Ken Hub provides an overview of the circulatory system, including its components such as the heart, blood vessels, and blood. It explains the pulmonary and systemic circuits, the heart's anatomy and function, and the types of blood vessels. The tutorial also covers the components of blood and their functions. The video concludes with a call to explore more resources on Ken Hub.
