Homework Answers
Here the answer is C
The blood pressure is the force applied by the blood column on the blood vessel. Here we have to consider force and radius of the vessel wall
In the question it is said that cross section is increased by a factor 2 indicating radius will also increase by a factor 2
By the formula of pressure that is force divided by area of the circle(blood vessel)
Pressure is inversely proportional to area and formula for area of circle is pie multiplied by radius square which indicates that pressure is inversely proportional to radius square
Here the cross section is increased by a factor of 2 therefore radius also increase by a factor of 2
Since pressure inversely proportional to radius square pressure decrease by a factor of 4

BLOOD AND FLUID QUESTION 1 (0A patient's blood pressure taken at the arm is 120 mmHg systolic and 70 mmHg diastolic. What would you expect the blood pressure (systolic and diastolic pressures) to be at the top of the head given that this point is 40 cm above the measurement point? Remember blood pressure is a gauge pressure and that 1 kPa = 7.5 mmHg. (The density of blood is about 1060 kg/m.) Choose one: a. 89...

The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...
