Respiratory and Skeletal System

By : Nash Tannehill

Respiratory System

The Respiratory System supplies the blood with oxygen so it can transport throughout the body. Alveoli give the lungs a big surface area, the oxygen diffuses from the air in the alveoli into the blood. The carbon dioxide diffuses from the blood into the air in the alveoli.

Diseases in the Respiratory System

Pneumoconiosis is a disease where toxic particles get trapped in the lungs. You might notice it from tightness in your chest or a shortness in breath. Treatments include not smoking, using oxygen and avoiding dust exposure. (Can get this from working in an construction site or a dusty environment.)


Emphysema is a disease where the air sacs in the lungs get destroyed and also the loss of respiratory membrane. Look for shortness of breath (long term smokers). Not smoking and medication are treatments even though its not curable.

Skeletal System

The skeletal systems main function is to support the body and make new blood cells. Ligaments connect the bones together and the tendons connect muscle tone bone. The nerves transmit sensations to the brain or spinal cord.

Diseases in the Skeletal System

Osteoporosis is a disease where the bones become very fragile and are prone to fracture. There might be pain in the back and maybe loss of height, the treatment is calcium carbonate to strengthen the bones.


Leukemia is the cancer of white blood cells, rashes and pain on the bones of joints can occur. Chemotherapy can help dramatically.
