Assume that CO remains constant in the following choices. Arteries have a. lots of smooth muscle tissue. Parasympathetic stimulation to the heart a. increases your heart rate. Atherosclerosis, or fat deposition inside artery walls, may a. decrease vessel diameter. Gas exchange between systemic tissues and the blood is called a. external respiration.
Respiratory acidosis is often a consequence of diseases like emphysema.
The normal respiratory response to exposure to smoke or air pollution includes increased a. cilia activity. You are at a high altitude site and the total air pressure is 300 mmHg. Increased sympathetic stimulation a. dilates your airways. P O 2 c. increased P CO 2 d. increased P O 2 47. In addition to respiratory acidosis, emphysema can lead to a. decreased mucous production.
