which lung volumes were affected by the additional dead space? did they increase or decrease?

These blood vessels also branch into smaller and smaller units ending with capillaries, which are in direct contact with each alveolus. Blood vessels from the pulmonary arterial system accompany the bronchi and bronchioles.

The oxygen transferred through the system is finally transferred to the bloodstream at the alveoli. At the end of each alveolar duct are clusters of alveoli. After many subdivisions, the bronchioles end at the alveolar ducts. The bronchi subdivide several times into smaller bronchi, which then divide into smaller and smaller branches called bronchioles. One bronchus serves the right lung and the other serves the left lung. The trachea divides into two main bronchi upon reaching the lungs.

From there it passes through the pharynx on its way to the trachea. The smooth functioning of the entire system is directed by the brain and the autonomic nervous system.Īir containing oxygen enters the body through the nose and mouth. The heart creates the force to move the blood at the right speed and pressure throughout the body. The bloodstream takes oxygen from the lungs to the rest of the body and returns carbon dioxide to them to be removed.

The bloodstream, heart and brain are also involved. It includes the diaphragm and chest muscles, the nose and mouth, the pharynx and trachea, the bronchial tree and the lungs. The respiratory system is the body's link to its supply of oxygen. Every cell in the body needs a constant supply of oxygen to produce energy to grow, repair or replace itself and to maintain normal vital functions.
