Functions of Cardiovascular and Respiratory Systems

Transports nutrientsRemoves gaseous waste from bodyTransports oxygen and removes carbon

dioxideFights disease Transports hormones

Related Organs

Lungs: store the body’s oxygen supply. Draws oxygen into the body and carbon dioxide out of the body.

Heart: pumps blood to the entire body. Contracts and relaxes

Blood vessels: transport blood throughout the entire body. Shaped like hollow tubes.

How do these systems interact?

They both work to get oxygen to tissues and getting carbon dioxide out.

The respiratory system works to supply oxygen for the blood.

Every time you take a breath, you are pumping oxygen into your blood stream.

This oxygen-rich blood is then brought to each part of your body through blood vessels.

Diseases/What could go Wrong

Hypertension: also known as high blood pressure. This causes the heart to work harder and can lead to a heart attack, stroke, or kidney failure.

Asthma: A disease of the lungs that makes it harder to breath or take in oxygen. Lungs are usually under more stress and weaker.

Cystic Fibrosis: A condition where thick mucus forms in the lungs and other organs. This mucus blocks airways and makes it hard to breath.

Ailments can also arise out of airborne substances and organisms.
