What type of muscle tissue is located in our body's blood vessels

Which blood vessel contains valves?

The transfer of fluid, nutrients, and waste products into and out of the tissue spaces occurs where?

What class of medication causes the smooth muscle of the arterial walls to relax (or dilate)?

a section of an artery that has become abnormally widened because of a weakening of the arterial wall (can sometimes form a saclike extension of the arterial wall)

procedure where balloon is inserted into the vessel until it reaches the affected area of plaque, then balloon is inflated and pushes plaque out to either side of affected vessel

Once the coronary vessels have supplied blood to the heart muscle, the deoxygenated coronary blood empties into what structure?

A specialized type of radiography which is used to visualize arteries

Which vessel contains precapillary sphincters?

Oxygen-rich blood returns from lungs via which structure(s)?

The medical word for heart attack is:

The general term used to describe disease of the myocardial tissue:

Class of drug which prevents clot formation in patients

A medication type which blocks norepinephrine receptors in cardiac muscle, thereby reducing the rate and strength of the heart beat

A drug which slows and increases the strength of cardiac contractions

Left heart failure is the most common type of heart failure, and is also referred to as:

The volume of blood pumped by one ventricle per minute:

Heart rate (HR) x stroke volume (SV) =

Another word for extra-systole is

The normal, natural pacemaker of the heart is the :

a graphic record of the heart's electrical activity obtained using an electrocardiograph apparatus

The AV node and atrial walls depolarizing shows which change on an EKG/ ECG strip?

Which of the following is not a factor that influences blood pressure?

Which type of drug promotes water loss by increasing urine output?

_________ describes any force that acts against the flow of blood in a blood vessel

Any pericardial fluid, pus, or blood that may accumulate in the space between the two pericardial layers and impair the pumping action of the heart is called

contraction of the heart is also called

The electrical activity that triggers the contraction of the heart muscle is called:

When does the myocardium receive oxygen-rich blood?

The contraction and relaxation of the four heart chambers

Chest pain that occurs when the myocardium is deprived of adequate oxygen; often acts as warning that coronary arteries are not able to supply enough oxygen to heart

A procedure designed to treat coronary blockages where a device is inserted into a blocked artery to force open a channel for blood flow

The area slightly left of the center of the chest

A lubricant that reduces friction as the heart contracts and relaxes

The thick layer of muscle tissue that divides the left and right sides of the heart

Exits the right ventricle into the pulmonary artery

Exits the left atrium into the left ventricle

The largest part of the heart; the lower-left area

This term means "listening to"

They lead to the lungs and transport oxygen-poor blood

Deoxygenated blood from the veins of the coronary circulation will drain into what structure first?

Blood returns from the body to the right atrium through these inferior and superior structures

Listening to this is considered the most accurate method of measuring heart rate

A fatty, plaque-like substance that can narrow or block coronary vessels

Blood enters these after leaving the arterioles. Their walls are just one cell thick.

The natural pacemaker for the heart

What anatomic structure electrically and physically join muscle fibers together to conduct an impulse throughout a chamber of the heart without stopping?

Each complete heart beat is called a

The “backup” pacemaker, it transfers impulse to both ventricles

The upper blood pressure number, which reflects the highest pressure exerted against artery walls during ventricular contraction

The lower blood pressure number, which reflects the lowest pressure exerted against artery walls during ventricular relaxation

Diagnostic or therapeutic radiography (radiological imaging) of the heart and blood vessels

Small, computer-driven defibrillator that analyzes the patient’s rhythm, selects the appropriate energy level, charges the machine, and delivers a shock to the patient

The volume of blood ejected from the ventricle during each beat

Emergency procedure that provides manual external cardiac compression and sometimes artificial respiration

What class of medication causes the smooth muscle of the arterial walls to relax (or dilate)?

Delivery of an electrical shock with the goal of ending ventricular fibrillation and restoring normal sinus rhythm

Creation and study of graphic records (electrocardiograms) of electric currents originating in the heart

Device that can trigger the mechanical contractions of the heart by emitting periodic electrical discharges

Protein released into the body by damaged heart muscle, considered the most accurate blood test to confirm the diagnosis of an MI (myocardial infarction)

The depolarization of the ventricles is associated with which part of the ECG/ EKG?

extra systoles are also known as

The volume of blood pumped by one ventricle per minute (average is 5 L)

the inability of the heart to pump enough blood to sustain life

This drug dilates or widens coronary blood vessels, increasing the flow of oxygenated blood to the myocardium; often used to treat angina pectoris

A general term for any disease affecting the heart (myocardial )tissue

Restoration of normal sinus rhythm (N S R) by chemical or electrical means
