Chapter 8, Problem 4AWK
Summary Introduction

To review:

The reasons behind standing for long periods may lead to circulatory issues. Also, wearing something tight on the legs may prevent these problems.

Introduction:

Workers who spend most of the time by standing develop pooling of blood at the lower end of the legs due to gravity. The entire body weight sits on the two legs of the human beings. This causes strain and tension on the legs of the species.

In human clinical practice, blood pressure is measured on the arm, listening for pulse sounds in the pocket of the elbow. From this location, we can measure blood pressure fairly precisely whether the person is sitting, standing, or laying down as long as the arm is kept at the person’s side. If the arm is moved, or if we choose the leg to measure blood pressure instead, the position of the person (sitting, laying down, standing) will dramatically change the blood pressure reading that we measure. Given what you understand about blood pressure, explain why we can accurately measure pressure in any position if the arm is kept at the side, but it changes so much if we were to measure from the legs.
Diastole and systole are terms that address the contracting and relaxing of the heart. Which of the following statements about diastolic and systolic blood pressure are true? Select all that apply. The diastolic blood pressure reading is the second number that is read and it's a measurement of the pressure of the arteries as the heart contracts and beats. The systolic blood pressure reading is the first number that is read and it's a measurement of the pressure of the arteries as the heart contracts and beats. The systolic blood pressure reading is the first number that is read and it's a measurement of the pressure in the arteries when the heart rests between beats. Systole refers to when the heart contracts and blood flows from atria into ventricles. The diastolic blood pressure reading is the second number that is read and it's a measurement of the pressure in the arteries when the heart rests between beats Diastole refers to when the heart contracts and the blood flows from the…

This figure shows the relationship between EDV and SV. Curve 2 is representatíve of a normal individual sitting on a bike, resting. There are two other curves illustrated and there are multiple points landmarked with a "o" and the letters "A to F". You can assume that the only changes in relevant variables are described in each question. If a variable is not mentioned you can assume that it has not changed. The starting point is "A". Select an appropriate pointif there was an increase in cardiac inotropy. 23 D. Stroke Volume (mL)
