Study Guide: Circulation of Blood

1

The term used to describe a collection of mechanisms that influence the active and changing circulation blood is

1

Blood flows because of

1

Determining the cardiac output is usually accomplished by

1

Which of the following has the ability to alter heart rate

1

A change in heart rate or stroke volume does not always change the heart's output, the amount of blood in the arteries, or the blood pressure

1

If blood pressure within the aorta or carotid sinus suddenly increases beyond the set point, the control center will increase vagal inhibition and return the blood pressure to normal.

1

The amount that the CO can increase above the resting value is called the inotropic factor.

1

The ejection fraction is related to the stroke volume

1

Peripheral resistance in arteries determines arterial blood pressure

( Viscocity, vasoconstriction, cardiac output, hypoxia, vasomotor pressure flex, hypercapnia, active hypermia, ischemic, perfusion, contractility ): thickness of blood
( Vasoconstriction, contractility, perfusion, ischemic, active hypermia, hypercapnia, hypoxia, vasomotor pressure flex, viscocity, cardiac output ): reduction in vessel diameter
( Perfusion, cardiac output, vasoconstriction, viscocity, vasomotor pressure flex, hypoxia, hypercapnia, active hypermia, ischemic, contractility ): flow through
( Cardiac Output, vasoconstriction, viscocity, vasomotor pressure flex, hypoxia, hypercapnia, active hypermia, ischemic, perfusion, contractility ): amount of blood that flows out of a ventricle of the heart per unit of time
( Hypoxia, vasoconstriction, cardiac output, viscocity, vasomotor pressure flex, hypercapnia, active hypermia, ischemic, perfusion, contractility ): deficiency of blood oxygen
( Ischemic, contractility, perfusion, active hypermia, hypercapnia, hypoxia, vasomotor pressure flex, viscocity, cardiac output, vasoconstriction ): inadequate blood supply
( Active hyperemia, vasoconstriction, cardiac output, viscocity, vasomotor pressure flex, hypoxia, hypercapnia, ischemic, perfusion, contractility ): local vasolidation
( Contractility, perfusion, ischemic, active hypermia, hypercapnia, hypoxia, vasomotor pressure flex, viscocity, cardiac output, vasoconstriction ): the ability of a muscle cell to shorten to product movement
( Hypercapnia, vasoconstriction, cardiac output, viscocity, vasomotor pressure flex, hypoxia, active hypermia, ischemic, perfusion, contractility ): excess carbon dioxide
( Vasometer pressure flex, vasoconstriction, cardiac output, viscocity, hypoxia, hypercapnia, active hypermia, ischemic, perfusion, contractility ): inititiated by a change in arterial blood pressure

1

The ability of blood vessels to expand and adapt to higher pressure and maintain normal flow is called the .

1

Increased respirations and increased tend to coincide.

1

is the exchange of materials between plasma in the capillaries and the surrounding interstitial fluid of the systemic tissues.

1

tends to promote diffusion of fluid into the plasma.

1

The more ADH that is secreted, the more water will be into the blood from the urine and the greater the blood plasma volume will become.

1

of aldosterone secretion changes blood plasma volume.

1

is secreted by specialized cells in the atrial wall in response to overstretching.

1

is high blood pressure.

1

The diastolic blood pressure is

1

With a blood pressure of 120/80, the number 80 indicates

1

The mean arterial pressure MAP for a BP of 130/90 is

1

is the apparatus used to measure blood pressure.

1

If blood gushes forth in spurts with considerable force, you have most likely cut an .

1

The pressure points can be used to stop bleeding.

1

Starling's law of the heart states that

1

The vagus nerve is said to act as a ( brake, temperature monitor, positive feedback loop, ejection mechanism ) on the heart.

1

Under normal conditions, blood viscosity changes

1

The popliteal pulse point is found

1

Peripheal resistance is primarily affected by

1

Septic shock is caused by

1

Hypovolemic shock is caused by

1

The shift of the blood reservoir to the veins in the legs when standing is called the

1

Fick's formula is used to determining

1

The minute volume is equal to the

1

The chief determinant of arterial blood pressure is the of blood in the arteries.

1

Factors that affect the strength of myocardial contraction and, therefore, stroke volume are factors.

1

Starling's law of the heart states that within limits, the longer, or more stretched, the heart fibers art the beginning of contraction, the is their contraction.

1

The is the ratio of the stroke volume to the end-diastolic volume (EDV).

1

The pumping work that the heart must do to push blood into the arteries is known as .

1

The hormone most known as a heart accelerator is .
