Question
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.
Why is it important to not leave an inflated blood pressure cuff on the arm for too long?
Think: What are you doing to blood flow to the distal arm when you inflate the cuff?
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…

- Which of the following statements best describes systolic blood pressure? Systolic blood pressure depends upon the force of the heart contractions - the stronger the contractions the higher the systolic pressure will be. Systolic blood pressure depends on how tightly the cuff of the sphygmomanometer is tightened. Systolic blood pressure depends upon the resistance of the blood vessels - the greater the resistance to blood flow the higher the systolic pressure will be. Systolic blood pressure depends upon the force and frequency of the heart contractions - the stronger and more frequent the contractions the higher the systolic pressure will be.arrow_forwardtwo 50-year-old men are trying to determine their risk for developing arteriosclerosis. John jogs three times a week, maintains a healthy weight and eats a diet low in saturated fats. Thomas rarely exercises, is overweight, and only occasionally eats healthy meals. Based on your knowledge of the cardiovascular system and atherosclerosis, which man do you think is more at risk for developing the disease? What other factors could put a person at risk for arteriosclerosis?arrow_forwardWhich of the following is the correct sequence of blood flow through pulmonary circulation? Group of answer choices Right atrium → right ventricle → pulmonary arteries → pulmonary capillaries (in lungs) → pulmonary veins → left atrium Left atrium → left ventricle → pulmonary arteries → pulmonary capillaries (in lungs) → pulmonary veins → right atrium Right atrium → right ventricle → pulmonary capillaries (in lungs) → pulmonary arteries → pulmonary veins → left atrium Left atrium → left ventricle → pulmonary capillaries (in lungs) → pulmonary arteries → pulmonary veins → right atrium Left atrium → left ventricle → pulmonary veins → pulmonary arteries → pulmonary capillaries (in lungs) → right atriumarrow_forward
- Which of the following best describes the primary role of resistance vessels? Group of answer choices a.Providing nutrient supply to the walls of larger vessels b. They regulate arterial blood pressure and blood flow within the organs. c. Ensuring blood storage during periods of low cardiac output d. Directing blood flow to specific organs based on demandarrow_forwardAs blood flows from the aorta to the arteries, arterioles, and capillaries and through the venous circulation, it encounters various resistances to flow, which results in pressure drops. Using the table, calculate the resistance for an artery and a capillary. (Note: The viscosity of the blood is 3.5 × 10-3 Pa-s.)arrow_forwardYou wanted to prepare a fish dish for your grandfather that he loves the dried salted Codfish. But you noticed that this might be causing a problem for your elder grandfather since he has hypertension, what would you do to remove the salt from the fish?

Pick two answers: kidneys, heart, digestive organs, brain.arrow_forwardThe events of the cardiac cycle cause cyclical changes in left ventricular pressure and volume over time. Another way to represent these events is with a pressure-volume loop, as shown below. Drag the labels from the left into the appropriate boxes on the pressure- volume loop to demonstrate your understanding of the cardiac cycle. Aortic valve closure AV valve opening Systolic pressure Isovolumetric relaxation Isovolumetric contraction 120 Diastolic pressure Ventricular filling 80 End-diastolic volume Ventricular ejection 40 AV valve closure End-systolic volume Aortic valve opening 60 120 LV volume (mL) O McGraw-Hill Education Reset LV pressure (mm Hg)arrow_forwardMrs. Debbie Morgan is a 45-year-old female who works as a stocking clerk for a local home improvement store. While she was at work today a large box of metal rivets fell from a 20-ft.-high overhead shelf, striking her outstretched arm and knocking her to the ground. The ambulance personnel reported that she had lost quite a bit of blood at the accident scene and was “knocked out” when they arrived. To minimize further hemorrhage, the paramedics applied a pressure bandage to her arm. You meet the paramedics as they bring Mrs. Morgan into the emergency room and begin to assess her for injuries. She is awake and alert, but complaining of severe left arm and back pain, plus she has a “killer headache.” To fully examine her injuries you remove four blood-soaked bandages from her arm. You notice a large open wound on her arm with what appears to be bone tissue sticking out of the skin. She also has bruises covering her left shoulder, left wrist, and lower back. To determine the extent of her…arrow_forward
