Study Guide: Circulation of Blood

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

Blood flows because of

Determining the cardiac output is usually accomplished by

Which of the following has the ability to alter heart rate

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

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.

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

The ejection fraction is related to the stroke volume

Peripheral resistance in arteries determines arterial blood pressure

[blank_start]Viscocity[blank_end]: thickness of blood [blank_start]Vasoconstriction[blank_end]: reduction in vessel diameter [blank_start]Perfusion[blank_end]: flow through [blank_start]Cardiac Output[blank_end]: amount of blood that flows out of a ventricle of the heart per unit of time [blank_start]Hypoxia[blank_end]: deficiency of blood oxygen [blank_start]Ischemic[blank_end]: inadequate blood supply [blank_start]Active hyperemia[blank_end]: local vasolidation [blank_start]Contractility[blank_end]: the ability of a muscle cell to shorten to product movement [blank_start]Hypercapnia[blank_end]: excess carbon dioxide [blank_start]Vasometer pressure flex[blank_end]: inititiated by a change in arterial blood pressure

The ability of blood vessels to expand and adapt to higher pressure and maintain normal flow is called the [blank_start]stress[blank_end] [blank_start]relaxation[blank_end] [blank_start]effect[blank_end].

Increased respirations and increased [blank_start]circulation[blank_end] tend to coincide.

[blank_start]Capillary[blank_end] [blank_start]exchange[blank_end] is the exchange of materials between plasma in the capillaries and the surrounding interstitial fluid of the systemic tissues.

[blank_start]Osmotic[blank_end] [blank_start]pressure[blank_end] tends to promote diffusion of fluid into the plasma.

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

[blank_start]Renin[blank_end] [blank_start]Angiotensin[blank_end] [blank_start]Aldosterone[blank_end] [blank_start]System[blank_end] of aldosterone secretion changes blood plasma volume.

[blank_start]ANH[blank_end] is secreted by specialized cells in the atrial wall in response to overstretching.

[blank_start]Hypertension[blank_end] is high blood pressure.

The diastolic blood pressure is

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

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

[blank_start]Sphygomomanometer[blank_end] is the apparatus used to measure blood pressure.

If blood gushes forth in spurts with considerable force, you have most likely cut an [blank_start]artery[blank_end].

The pressure points can be used to stop [blank_start]arterial[blank_end] bleeding.

Starling's law of the heart states that

The vagus nerve is said to act as a [blank_start]brake[blank_end] on the heart.

Under normal conditions, blood viscosity changes

The popliteal pulse point is found

Peripheal resistance is primarily affected by

Septic shock is caused by

Hypovolemic shock is caused by

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

Fick's formula is used to determining

The minute volume is equal to the

The chief determinant of arterial blood pressure is the [blank_start]volume[blank_end] of blood in the arteries.

Factors that affect the strength of myocardial contraction and, therefore, stroke volume are [blank_start]inotropic[blank_end] factors.

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

The [blank_start]ejection[blank_end] [blank_start]fraction[blank_end] is the ratio of the stroke volume to the end-diastolic volume (EDV).

The pumping work that the heart must do to push blood into the arteries is known as [blank_start]cardiac[blank_end] [blank_start]afterload[blank_end].

The hormone most known as a heart accelerator is [blank_start]epinephrine[blank_end].

During exercise blood from reservoirs is redistributed to more active structures such as [blank_start]skeletal[blank_end] muscles and the heart.

The blood vessel commonly used to perform blood pressure readings is the [blank_start]brachial[blank_end] [blank_start]artery[blank_end].

The sounds made during the measurement of a blood pressure are called [blank_start]Korotkoff[blank_end] [blank_start]sound[blank_end].

Blood flows most rapidly in the [blank_start]arteries[blank_end] and most slowly in the [blank_start]capillaries[blank_end].
