For an accurate measurement of cardiovascular activity, researchers typically: D) measure the number of heartbeats per minute.
<h3>What is cardiac cycle?</h3>
Cardiac cycle is a process that involves the complete heartbeat of the human heart, which comprises sequential alternating contraction and relaxation of the atria and ventricles, so as to cause blood to only flow in one direction throughout the human body during any cardiovascular activity.
As a general, researchers should typically measure the number of heartbeats of a person per minute, so as to ensure an accurate measurement of cardiovascular activity.

Answer and Explanation:
Phelps criticized Friedman's position, because he said it was totally irrelevant to analyze the tax functions of inflation without assessing product demand, as Friedman suggested in his theory. He stated that this would only be possible if there was a way to predict an optimal rate of inflation in different situations of demand and supply, otherwise, in Phelps' words it would be the same as "Professor Friedman gave us Hamlet without a prince".
Phelps' positioning would be better considered by the RBC model, since this model is based on real and not imaginary facts.
Answer:
Surfactant increases airflow. It has this effect on airflow because it reduces resistance to lung inflation. Airflow increased as predicted.
Explanation:
Pulmonary surfactant is a complex mixture of lipids and proteins secreted by the Type II alveolar cells. The major component of surfactant, dipalmitoyl-phosphatidylcholine (DPPC), is an amphiphatic phospholipid. The main function of the pulmonary surfactant is to reduce the surface tension at the air/liquid interface in the lungs by forming lining layer between the aqueous airway liquid and the inspired air. prevents alveolar and airway collapse at end-expiration and thus allows cyclic ventilation of the lungs. It decreases surface tension in the alveoli making it easier for the alveoli to increase surface area for gas exchange. By lowering alveolar surface tension, pulmonary surfactant provides two important benefits:
(1) it increases pulmonary compliance, reducing the work of inflating the lungs; and
(2) it reduces the lungs’ tendency to recoil, so they do not collapse as readily.
