Explanation:
The right answer is Electrocardiography (or Electrocardiogram).
In a typical plot, one can notice five characteristic waves. They are called P, Q, R, S and T. The illustration below shows what a normal electrocardiogram looks like:
* the P wave marks the depolarization during the contraction of the atria;
* the PR interval indicates the time required to transmit the electrical impulse of the sinus node of the atria to the ventricular muscles;
* the QRS complex marks depolarization and ventricular contraction;
* the QT interval corresponds to the global ventricular repolarization;
* T wave refers to the end of ventricular repolarization.
Answer:
Explanation:
From the capillaries, blood passes into venules, then into veins to return to the heart. Arteries and arterioles have relatively thick muscular walls because blood pressure in them is high and because they must adjust their diameter to maintain blood pressure and to control blood flow.
Answer: This is known as RISK ASSESSMENT.
Risk assessment can be defined as the determination of the potential impact of an individual risk by measuring or otherwise assessing both the likelihood that it will occur and the impact if it should occur, and then combining the result according to an agreed rule to give a single measure of potential impact.
