Question
Chapter 10, Problem 10CR
Summary Introduction
To review:
In what way heart failure can cause a decrease in the diffusion of oxygen and carbon dioxide between the blood and the alveoli.
Introduction:
Congestive heart failure refers to the chronic heart condition, which is characterized by the incompetent blood pumping ability of the heart. The common manifestation includes chest pain, fatigue, and edema (swelling in the leg and feet).

- Pneumonia interferes with CO2 elimination and O₂ uptake primarily by: Slowing diffusion by reducing the surface area of alveoli Reducing air flow into and out of the lungs by reducing the cross sectional area of the airways Decreasing the partial pressure of the air in the alveoli.

- Asthma is a very common disease. It is characterized by widespread narrowing of the bronchioles and formation of mucus plugs, producing symptoms of wheezing, shortness of breath, and coughing, and is caused by the release of factors during an allergic response. Explain why the narrowing of bronchioles, rather than that of the larger bronchi, is the source of the airflow restriction, and why inhaling dilating agents can bring relief during an asthma attack.arrow_forwardDescribe the partial pressure of O2 and CO2 in the alveoli,lung capillaries, tissue capillaries, and tissuesarrow_forwardWill the gases continue to diffuse in these directions, or will they stop at some point? For example, the partial pressure of O2 in the alveoli is 104 mmHg and the partial pressure of O2 in the blood in the pulmonary capillaries is 40 mmHg.
