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 veins into the ventricles Previous Next

Figure 40.11 Which of the following statements about the heart is false? The mitral valve separates the left ventricle from the left atrium. Blood travels through the bicuspid valve to the left atrium. Both the aortic and the pulmonary valves are semilunar valves. The mitral valve is an atrioventricular valve.
A blood pressure of 130/80 is measured using an instrument that measures blood pressure called a sphygmomanometer. Which of the following rows correctly identifies the measured value and description of the systolic pressure? Measured Value Row Description (mmHg) pressure in the arteries when the heart contracts 130 pressure in the arteries when the heart relaxes 130 pressure in the arteries when the heart contracts 80 pressure in the arteries when the heart relaxes 80
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.
The 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)
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.
Which of the following is correct regarding the flow of blood in reference to the left side of the heart? a. Blood flows from the left atrium, through the bicuspid valve, into the left ventricle, through the aortic semilunar valve, and then into the aortic arch b. Blood flows from the left atrium, through the aortic semilunar valve, into the left ventricle, through the bicuspid valve, and then into the aortic arch c. Blood flows from the left atrium, through the bicuspid valve, into the left ventricle, into the aortic arch, through the aortic semilunar valve, and then into systemic arterial system
The heart is resting during Select one: ventricular systole. the ejection period. ventricular diastole. atrial systole.
Determine whether the statement is either true or false. To clearly hear the heart sound of the bicuspid valve, a stethoscope should be placed to the left of the sternum at the second intercostal space. At late diastole, the atria and ventricles are relaxed and the aortic semilunar valve is open. During ventricular contraction all the blood is forced out of the ventricles.
In the given table, three of the anatomical and physiological terms are similar or related; one does not belong with the other three. Choose the term that does NOT belong in each of the following groups.

When seated in a normal upright position, what would you expect the systolic blood pressure to be when measured from the arm while it is raised above the head? Higher than when measured from the arm in its relaxed resting position by your side Not detectable since systolic pressure can only be detected from arteries at or below the level of the heart The same as when measured from the arm in its relaxed resting position by your side since position has no effect on systolic pressure Lower than when measured from the arm in its relaxed resting position by your side.

Choose all the statements that are correct. When the heart beats, first the right side of the heart contracts, and then the left side of the heart contracts. That is one heartbeat. The sympathetic nervous system speeds up the heart rate and the parasympathetic system slows down heart rate. M Bradycardia is when the heart beats faster than normal. The SA node is the pacemaker of the heart. Coronary arteries deliver blood to the muscle of the heart. A heart attack is a myocardial infarction. The ECG (EKG) has a QRS wave that represents ventricular depolarization (the message to tell the ventricle to contract. The heart needs nerve stimulation in order to contract.
