Blood Pressure Physiology

Question 1

Measure of the force the blood exerts against the blood vessel walls.

Answer 1

Blood Pressure Physiology

Question 2

ventricles contract, blood is forced into the arteries, and the pressure reaches a maximum value.

Answer 2

SYSTOLIC PRESSURE

Question 3

ventricles relax, blood pressure in the arteries falls to minimum value.

Answer 3

DIASTOLIC PRESSURE

Question 4

Standard unit of measurement millimeters of mercury (___)

Answer 4

mmHg

Question 5

AUSCULTATORY METHOD

Answer 5

-uses a stethoscope.

Question 6

hearing things in a stethoscope

Answer 6

Auscultation

Question 7

Pressure at which the first Korotcoff sound is heard is the ___.

Answer 7

systolic pressure.

Question 8

Pressure at which the last Korotkoff sound is heard is the ___.

Answer 8

diastolic pressure.

Question 9

Pressure at which the last Korotkoff sound is heard is the ___.

Answer 9

diastolic pressure.

Question 10

No longer turbulent, the sound ___ completely.

Answer 10

disappears

Question 11

Resistance to blood flow is related to the diameter of the blood vessel.

Answer 11

Pressure and Resistance

Question 12

Smaller the diameter of the blood vessel, the greater the resistance to flow; the more rapid decreases in pressure as blood flows through smaller vessels.

Answer 12

Pressure and Resistance

Question 13

Most rapid decline in blood pressure occurs in the arterioles and capillaries because their small diameters increase the resistance to blood flow.

Answer 13

Pressure and Resistance

Question 14

Difference between systolic and diastolic pressures.

Answer 14

Pulse Pressure

Question 15

volume of blood ejected by the heart per beat

Answer 15

Stroke Volume

Question 16

ability of a blood vessel wall to expand and contract passively with changes in pressure

Answer 16

Vascular Compliance

Question 17

Pressure wave that results from the ejection of blood from the Left Ventricle into the aorta.

Answer 17

PULSE

Question 18

this area gives soft pulses.

Answer 18

Axillary artery, Brachial artery, Radial Artery.

Question 19

To know if a person is dead or alive.

Answer 19

Common carotid artery

Question 20

1. Reduced elasticity and thickening or arterial walls result in hypertension and decreased ability to respond to changes in blood pressure.
2. Atherosclerosis is an age-related condition.
3. The efficiency of capillary exchange decrease with age.
4. Walls of veins thicken in some areas and dilate in others. Thromboses, emboli, varicose veins, and hemorrhoids are age-related conditions.

Answer 20

Effects of Aging on the blood Vessel

Question 21

In pressure and resistance, The smaller the diameter of the blood vessel, the ____ the resistance flow.

Answer 21

greater

Question 22

In pressure and resistance, The most rapid decline in blood pressure occurs in the ___ and ___ because their small diameters increase the resistance to blood flow.

Answer 22

arterioles and capillaries

Question 23

Stroke volume is ___ (directly or indirectly) proportional to Pulse Pressure.

Answer 23

Pulse Pressure

Question 24

Vascular compliance is ____ proportional to Pulse Pressure

Answer 24

Inversely

Question 25

Pulse is felt at locations where large arteries are close to the ____.

Answer 25

surface of the body.

Question 26

The two factors that affect pulse pressure are the __ and ___

Answer 26

Stroke Volume ad Vascular compliance
