Atelectasis, or lung collapse, occurs when a bronchiole becomes plugged.

__________, or lung collapse, is a homeostatic imbalance that occurs when a bronchiole becomes plugged.

Chronic bronchitis, emphysema, asthma, tuberculosis, and lung cancer

Disease

Lung Cancer - Overview

Lung cancer is the leading cause of cancer death in both men and women in North America, causing more deaths than breast, prostate, and colorectal cancers combined. This is tragic because lung cancer is largely preventable&mdash;nearly 90% of lung cancers are the result of smoking.

Lung cancer is among the easiest forms of cancer to successfully treat and cure.

Paralysis of the intercostal muscles would hinder thoracic expansion and lead to a decrease in the total respiratory compliance.

Calcification of the coastal cartilages would hinder thoracic expansion and lead to a decrease in the total respiratory compliance.

Deformity of the thorax would hinder thoracic expansion and lead to a decrease in the total respiratory compliance.

Which of the following conditions would NOT decrease the total respiratory compliance?

Chronic Bronchitis vs Emphysema Pathophysiology, Treatment

Tuberculosis - causes, symptoms, diagnosis, treatment, pathology

The baby's cilia are damaged or destroyed, and only coughing can prevent mucus from accumulating in the lungs.

When too little surfactant is present, surface tension forces can collapse the alveoli. This is the problem faced by newborns with infant respiratory distress syndrome (IRDS), a condition found in premature babies. Since inadequate pulmonary surfactant is produced until the last two months of fetal development, babies born prematurely often are unable to keep their alveoli inflated between breaths because of a lack of surfactant.

Histamine and other inflammatory chemicals cause the baby's bronchioles to constrict.

The pleurae produce an excessive amount of fluid, putting pressure on the baby's lungs, hindering breathing.

The baby is unable to keep his or her alveoli inflated between breaths because of a lack of surfactant.

Which of the following occurs during infant respiratory distress syndrome (IRDS)?

Cold viruses, streptococcal bacteria, and various allergens can cause rhinitis, an inflammation of the nasal mucosa accompanied by excessive mucus production, nasal congestion, and postnasal drip.

__________ is the inflammation of the nasal mucosa accompanied by excessive mucus production, nasal congestion, and postnasal drip.

Histotoxic hypoxia occurs when body cells are unable to use O<sub>2</sub> even though adequate amounts are delivered, and it is usually the consequence of metabolic poisons, such as cyanide.

Which form of hypoxia occurs when body cells are unable to use O<sub>2</sub> even though adequate amounts are delivered? (This type of hypoxia is usually the consequence of metabolic poisons, such as cyanide.)

Emphysema is distinguished by permanent enlargement of the alveoli, accompanied by destruction of the alveolar walls and loss of lung elasticity.

Emphysema is distinguished by permanent enlargement of the alveoli and loss of lung elasticity.
