Pulmonary arterioles respond to different factors than systemic arterioles because in the lungs, the blood supply is receiving oxygen and delivering carbon dioxide, while in the systemic circulation, it is delivering oxygen, and receiving carbon dioxide. In the pulmonary circuit, arterioles will dilate in well-ventilated areas of the lungs to increase the rate of exchange between capillaries and well-ventilated alveoli. However, in poorly ventilated areas of the lungs, arterioles will constrict in order to re-route blood to well-ventilated areas. Now consider our case of pulmonary oedema, and how that will impact circulation in the pulmonary circuit. (Select two answers). O Pulmonary arterioles will dilate O Pulmonary arterioles will constrict O Pulmonary vascular resistance will increase O Pulmonary vascular resistance will decrease

After oxygen diffuses into lung capillaries, it also diffuses into _______ and binds with _______. a. tissue fluid; red blood cells b. tissue fluid; carbon dioxide c. red blood cells; hemoglobin d. red blood cells; carbon dioxide
How does hemoglobin help maintain the oxygen partial pressure gradient during gas transport in the body?
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.
Why does hemoglobin have high affinity for oxygen in arterial blood and lower affinity in capillaries beds? Explain in terms of blood oxygen pressure.
If there is increased hydrostatic pressure on the venous side of the capillaries leading to an increase in fluid moving into the tissues why would it cause ankle edema? What role does the lung play in development of that increased hydrostatic pressure in terms of alveolocapillary membrane/lung changes. What is the effect on oxygen diffusion from the alveolus, on pulmonary artery pressure and resultant changes to the right side of the heart)?
If a person has stopped breathing and is receiving pulmonary resuscitation, would it be better to administer pure oxygen or a mixture of oxygen and carbon dioxide? Why?
At high altitudes, the partial pressure of oxygen is lower. How might you expect this lower oxygen level to affect the ability of the blood to transport respiratory gases, and what would be the effect on respiring tissues?
It is not usually necessary to assess arterial blood gases when diagnosing and treating asthma. However, this information can sometimes be useful in severe asthma attacks. Suppose that a patient had a PO2 of 60mm hg and a PCo2 of 30mm hg when the patient first went to the emergency room. Explain how that could happen.
Using a flow diagram (arrows), describe the pathway of the pulmonary circulation. Indicate the relative amounts of oxygen and carbon dioxide in the vessels involved.
If there is decreased oxygen content in skeletal muscle tissue, arterioles supplying the skeletal muscles will ____. If there is decreased oxygen content in the alveoli, pulmonary arterioles will ____. Choose from the following: (A) dilate / dilate (B) constrict / constrict (C) constrict / dilate (D) dilate / constrict
If the partial pressure of oxygen in inhaled air was 80 mm Hg instead of 160 mm Hg, what would be the impact on oxygen transport in the body? Be sure to explain this in detail and to be clear about what you think will happen in all parts of the transfer of oxygen throughout the body.
Jumping into cold water may initiate the “diving reflex,” during which blood is shunted toward the head and away from the limbs. Under these conditions, why might you be able to hold your breath for an extended period?
