Exam 22: The Respiratory System

Your breathing rate is 12 breaths/minute;your tidal volume is 500 mL;your vital capacity is 4700 mL;and your dead air space is 150 mL.Your alveolar ventilation rate is __________ mL/min.

The addition of CO₂ to the blood generates __________ ions in the RBCs,which in turn stimulates RBCs to unload more oxygen.

In which condition are the lungs infected with Mycobacterium and produce fibrous nodules around the bacteria,leading to progressive pulmonary fibrosis?

Carbon dioxide is transported by all the following means except _________.

Hemoglobin releases the same amount of oxygen to all the tissues regardless of variations in their metabolic rate.

The rate of oxygen diffusion is affected by the pressure gradient of carbon dioxide.

Which of the following is a lung disease marked by abnormally few but large alveoli?

Erythrocytes do not carry out aerobic respiration;thus,they do not consume any of the oxygen they are transporting.

Which of the following is the term for a deficiency of oxygen or the inability to utilize oxygen in a tissue?

Polio can sometimes damage the brainstem respiratory centers and result in which condition?

Which law states that the total pressure of a gas mixture is equal to the sum of the partial pressures of its individual gases?

The pleurae and pleural fluid help prevent the spread of pulmonary infection to the pericardium.

Which of the following is caused by the chemical reactions of gases of the respiratory system?

The pH of the cerebrospinal fluid is monitored by which of these brainstem centers?

Conditions around metabolically active tissues do what to the oxyhemoglobin dissociation curve?

The anatomical dead space is greatest in which of the following situations?

The amount of air in excess of tidal volume that can be inhaled with maximum effort is the __________.

Upon inspiration,what is the name of the air in the conducting zone that is not available for gas exchange?

The expansion of the lungs during inspiration generates a pressure gradient causing air to flow into the lungs.This is an example of Boyle's law.

How is the vital capacity calculated?
