Why do you think the plot was not linear? (Hint: Look at the relationship of the variables in the equation.) How well did the results compare with your prediction? The increase in radius resulted in an increase flow rate, as predicted. ACTIVITY 2 Studying the Effect of Blood Viscosity on Blood Flow Rate 1.
Blood vessels, if constricted, increase SVR and blood pressure while vasodilation decreases SVR and blood pressure. The longer the length of the blood vessel(s), the greater the SVR, therefore, the greater the resistance, the greater the cardiac output and blood pressure must be to overcome the
Decrease 7. Did the minute ventilation increase, decrease, or not change with exercise? Increase See Table 3: Lung Capacities and Minute Ventilation See Graph: Comparison of Resting and Exercising Lung Capacities and Minute Ventilation DISCUSSION 1. Explain the change in ERV with exercise. Tidal Volume increases with exercise, which decreases the ERV 2.
LDH-1 level higher than that of LDH-2 is indicative of a heart attack or injury. One of the most important diagnosis uses for the LDH isoenzymes test is in the different diagnosis of myocardial Infarction or heart attack. The total LDH level rises within 24-48 hours after a heart attack. Peaks in two to three days and returns to normal in approximately five to ten days. An LHD-1 level a phenomenon known as ‘flipped LDH’, Is strongly indicative of a Heart attack.
By blocking beta receptors, the heart rate will be slowed and reduces demand for oxygen and contractility. By slowing the heart rate, diastole will increase and the time of coronary blood flow will increase. With a decreased heart rate and contractility, the amount of work the heart has will also decrease. Calcium channel blockers are used to treat

You correctly answered: d. oxygen level in the blood 4. Viscosity most directly affects You correctly answered: b. peripheral resistance. 02/09/15 page 1 Experiment Results Predict Question: Predict Question: What effect do you think increasing the viscosity will have on the fluid flow rate? Your answer : c. The fluid flow rate will decrease. Stop & Think Questions: What is the relationship between fluid flow and viscosity?
Pressure waves travel throughout the blood vessels, which can be felt by the further movement of the blood. When the heart contract, blood is expelled into the aorta and the aorta stretches. At this point the wave of distention is most distinct, but comparatively slow-moving. As it travels towards the peripheral blood vessels, it progressively diminishes and becomes faster. In the large arterial branches, its velocity is 7 to 10 m/s; in the small arteries, it is 15 to 35 m/s.
| - 1 -The device of measurement includes an inflatable cuff, a dial of measurement and a stethoscope.The bladder is inflated until the cuff compresses the artery of the arm, the blood does not pass anymore: the stethoscope perceives no noise. | | - 2 -Then the cuff is deflated slowly, the blood goes through the artery again: the stethoscope perceives a (click like) noise and the value of the blood pressure is read at the same time on the dial.The blood pressure measured at this moment is the maximal blood pressure, the systolic blood pressure. | | - 3 -The cuff continues to deflate slowly. The blood passes again
