The function of the cardiovascular system The Cardiovascular system circulates oxygen and nutrients to body cells and tissues. It also allows for removal of carbon dioxide and wastes from those cells and tissues. The cardiovascular system delivers hormones to targeted tissues‚ maintains body temperature‚ and helps defend the body. The cardiovascular system is made up of the heart‚ blood and blood vessels. The heart is the pump of the cardiovascular system. It consists of 4 chambers‚ which is

DEMONSTRATIONS AND STUDENT ACTIVITIES Classroom Demonstrations: 1. Film(s) or other media of choice. 2. Show a video of a beating heart‚ ideally with heart sounds. Stress that while the right side of the heart is a pulmonary pump and the left side a systemic pump‚ both atria contract at the same time and both ventricles contract at the same time. 3. Use a dissectible heart model to show heart structure. 4. Use a dissectible human torso model to point out the major arteries and veins of the body.

undesired systemic reactions. • Systemic Effects: Medication can be administered in a number of ways to achieve systemic effects. These are drugs that the body absorbs into the general circulation (ie‚ the blood and lymphatic fluids) and then transports to a specific body area or to the entire body. To achieve systemic effects‚ medications often are administered by transdermal application‚ mouth‚ or injection‚ although other methods‚ such as nasal inhalation‚ can also produce systemic
