Respiratory System

By: Sydney Archibald and Shelbie Rhodes

What is the function of the Respiratory System?

The function of the respiratory system is ot deliever air to the lungs. Oxygen in the air diffuses put of the lungs and into the blood, while carbon dioxide diffuses in the opposite direction, out of the blood and into the lungs.

Describe the features of alveoli that adapt them to gas exchange

The alveli had various features that let them adapt to gas exchange. A huge number of them inceases the surface ares for the process. Both of the walls of the capillaries and the aveoli are made up of single layer of cells, which decreases the distance bewteen them and permitting a faster gas exchange. Some of these cells in the alveoli wall produce a wet substance that lets gases dissolve and prevent alveoli from stickinh together. Then the blood capillaries which overes the aveoli are alow in oxygen concentration and high in carbon dioxide concentration, furthing ketting carbon dioxide diffuse out of the blood and oxygen into the blood.

How is carbon dioxide and oxygen are transported in the blood?

Oxygen enters the blood from the lungs and carbon dioxide is removed out of the blood into the lungs. The blood serves to transport both gases. Oxygen is carried to the cells while carbon dioxide is carried away from the cells.

What are 2 major disorders found in the Respiratory system?

Chronic Obstructive Pulmonary Disease (COPD) - Irritation of the lungs can lead to asthma, emphysema, and chronic bronchitis and people may develop 3 or 2 of these together. The main cause is smoking. Signs and symptoms are shortness of breath, a chronic cough, and experience frequent respiratory infections. There is no actual treatment but you can quit smoking to help.

Pneumonia - An infection of the aveoli which can be caused by various kinds of both bacteria and viruses. Tissue fluids accumulate in the aveoli reducing the surface area exposed to air. Symptoms and signs are cough, chest pains, difficulty breathing, fever, fatigue, nausea, mood swings, etc. Most causes of Pneumonia can be treated iwthout needing to go to the hospital. Oral antibiotics, rest, fluids, and home care are sufficient for complete consoildation.
