What produces the force that drives normal exhalation, and is the process active or passive? The diaphragm, active The intercostal muscles, active Elastic recoil of the lungs and chest wall, passive O Contractions of the abdominal muscles, active

How can problems with ventilation could affect someone's ability to carry out cellular respiration. *

Under conditions where normal breathing isn’t sufficient, other muscles will assist the diaphragm in changing the volume of the thoracic cavity. A muscle that increases the volume of the thoracic cavity will cause pressure to (↑/↓) which means that it is helping with forced (inspiration/expiration). A muscle that decreases the volume of the thoracic cavity will cause pressure to (↑/↓) which means that it is helping with forced (inspiration/expiration).

Describe inhalation and exhalation.  Be sure to include discussions of what triggers them and the role of muscles in effecting these actions. You should also discuss the volume and pressure changes that occur during inhalation and exhalation.

Discuss how oxygen is transported (respiratory system)

Describe the actions that occur during an inhalation and an exhalation.

When someone breathes in they can completely exchange old air for new air. True or false.

Which one of the following is a possibility for most of us in regard to breathing, by making a conscious effort? Justify your option. a) One can consciously breathe in and breathe out by moving the diaphragm alone, without moving the ribs at all b)The lungs can be made fully empty by forcefully breathing out all air from them c)One can breathe out air totally without oxygen d) One can breathe out air through eustachian tubes by closing both the nose and the mouth

Cigarette smoke irritates the lining of your airway, causing it to [6]; this makes the diameter of your airway [7] and slows the movement of air. Smoke also slows the movement of [8]. Is a "smoker's cough" due to damage of alveoli or bronchial tubes? [9] Is a long-term smoker's difficulty breathing due to damage of alveoli or bronchial tubes? [10] [11] is a lung disease caused by damage to the alveoli.

Take a breath; now breathe deeper, deeper, and deeper. Name the process you have just experienced. Let the breath out; force more and more air out until you gasp. Name the process you have experienced.
