Name, in correct order, the conducting portion of the respiratory system.
1. They warm, moisten, and filter incoming air.
2. They receive olfactory stimuli.
3. They provide a resonating chamber for speech sounds.
Name the function of the interior structures of the nose.
1. Pulmonary ventilation is the movement of air in and out of the lungs, inspiration occurs
when the pressure inside the lungs is lower than the atmospheric pressure. This is achieved by increasing the volume of the lungs. Expiration occurs when the pressure in the lungs is greater than the pressure of the atmosphere. This occurs when the size of the thoracic cavity decreases.
2. External respiration is the exchange of gases between the air in the alveoli and the blood.
3. Internal respiration is the exchange of gases between the blood and tissues.
Name and briefly describe the three basic processes of respiration.
Asthma is a reaction, usually allergic, characterized by attacks of wheezing and difficult breathing, spasms of the smooth muscles in the walls of smaller bronchi and bronchioles cause the passageways to close partially, resulting in an attack.
Define Asthma.
