Part A What is the speed of the blood in the aorta? Assume that the speed of sound in human body is 1540 m/s Express your answer to two significant figures and include the appropriate units. When the heart pumps blood into the aorta, the pressure gradient-the difference between the blood pressure inside the heart and the blood pressure in the artery is an important diagnostic measurement A direct measurement of the pressure gradient is difficult, but an indirect determination can be made by measuring the Doppler shift of reflected ultrasound Blood is essentially at rest in the heart when it leaves and enters the aorta, it speeds up significantly and according to Bornoulli's equation- the pressure must decrease. A doctor using ultrasound of 25 MHz measures a 5900 Hz frequency shift as the ultrasound reflects from blood ejected from the heart HA ? Value Units Submit Previous Answers Request Answer
