Components of the Cardiovascular System
Body cells require a constant supply of oxygen, water and nutrients as well as a means of removing waste products. To maintain homeostasis hormones also need transporting to tissues where they exert control. Finally heat needs distributing around the body. To achieve this the transport system must be rapid, direct and able to achieve a two way exchange. This is exactly what the cardiovascular system achieves by transporting a fluid containing cells, gases, nutrients, waste products, hormones and heat.
Just as the design of cells or their form relates to their function so too do the components of systems. The cardiovascular system has three components that enable it to achieve its functions, a pump, tubes and fluid.
From the list on the right drag and drop into the boxes on the left what you think are the three components.
You need to understand the form and function of these 3 components to understand how the cardiovascular achieves the role.
