Which of the following is a function of the cardiovascular system

Which of the following is a function of the cardiovascular system

Structure of the heart

Where is the heart located

What is the heart made up of

What is the function of the heart

What makes up the outer surface of the heart

What is the term for the muscle tissue of the heart

What is the inner surface of the heart

What lines the interior walls of the heart, chambers, and luminal surfaces of blood vessels

What are the chambers

What are the left and right sides of the heart separated by

What are the ventricles and atria separated by

What structure prevents backflow of blood back into the ventricles when blood is being pumped out

What is the cardiovascular system divided into

The systemic circulation makes up how much of blood volume

The pulmonary circulation makes up how much of blood volume

Both the systemic and pulmonary circulation has both venous and arterial systems

Only the pulmonary circulation has arterial and venous systems, the systemic circulation only has a venous system

The systemic arterial circulation is a low pressure system

The systemic arterial circulation is a high pressure system

Hydrostatic pressure is not necessary to perfuse tissues with a high resistance to blood flow

Hydrostatic pressure is required to perfuse tissues with a high resistance to blood flow

Which of the following statements is accurate to the pulmonary arterial and venous & systemic venous circulations

High pressures in venous systems may cause fluid to leak from the vessels and to accumulate as edema

Low pressures in venous systems may cause fluid to leak from the vessels and to accumulate as edema

Blood pressure

Blood pressure refers to systemic arterial blood pressure

Blood pressure refers to systemic venous blood pressure

Blood pressure refers to pulmonary arterial blood pressure

Systemic arterial blood pressure rises and falls in coordination with the circadian rhythm

Systemic arterial blood pressure rises and falls in coordination with the cardiac cycle

Systole

Diastole

What allows proper tissue perfusion & prevention of edema formation (capillaries and veins)

How does the contraction & relaxation of the heart occur

Difference between systolic and diastolic pressures

Increase in BP & resistance is caused by

What controls the vasoconstriction of arterioles

What NS is dominant at rest

At rest, blood flow is directed towards

Intrinsic ability for spontaneous depolarization & repolarization results in

Depolarization occurs ONLY when stimulated by a nerve ending

Depolarization occurs w/o stimulation by a nerve-ending

Cardiac tissues have ____________, which causes depolarization to occur w/o stimulation by a nerve ending

Muscle fibers w/in the RA =

Terminology for "listening to the heart" is ___________ ____________

Most important factor of the regulation of the heart is the

HR can be determined by various factors including body temperature

Term for normal heart rhythm

What is the sinus rhythm determined by

Arrhythmias can be

A bradyarrhythmia is

A tachyarrhythmia is

How is contractility of the myocardium determined by (at the molecular level

Which of the following has a high resistance to blood flow

What is required to perfuse the following tissues; heart, kidney, brain, & other tissues above the heart

How many parts is the cardiac cycle divided into

Systole corresponds to

Diastole corresponds to

Systole is when

Diastole is when

Common pulse point location for the cat

Common pulse point location of a dog

Cardiac muscle fibers are

Much like skeletal muscle, impulses travel cell to cell, via intercalated discs in a wave like fashion

unlike skeletal muscle, impulses travel cell to cell, via intercalated discs in a wave like fashion

The heart does not contract as a unit, but rather, the individual chambers contract intermittently

The heart contracts as a unit or not at all

What determines the rate of spontaneous depolarization of the SA node

An electrocardiogram CANNOT determine heart rate

An electrocardiogram can determine heart rate

Does the sympathetic NS impact level of contractility of the myocardium?

What can cause increase in rate & force of myocardial contraction by increasing the amount of calcium available
