Aorta - right common iliac - external iliac - femoral

Select the correct sequence of arteries carrying blood to the right thigh

Aorta - celiac - gastric

Select the correct sequence of arteries carrying blood to the stomach.

right atrium - tricuspic AV valve - right ventricle - pulmonary semilunar valve - pulmonary trunk

Select the correct sequence of blood flow through the heart.

artery - arteriole - capillaries - venule - vein

Select the correct sequence of blood flow.

SA node - AV node - AV bundle - Purkinje fibers

Select the correct sequence of impulse transmission in the heart.

superior mesenteric - hepatic portal vein - liver - hepatic vein - inferior vena cava

Select the correct sequence of veins carrying blood from the small intestine.

increased water intake

Select the response that does not affect blood pressure under normal conditions

Withstand a higher blood pressure than arteries

Select the response that is not a characteristic of veins.

large artery to a ventricle.

Semilunar valves prevent the flow of blood from a/an

Capillary - interstitial fluid - tissue cells

Select the correct sequence for the movement of materials from the blood to the tissue cells.

varicose veins.

A condition in which leg veins are dilated and swollen so their valves are not functioning is called

congestive heart failure

A disorder in which the heart is unable to pump out all of the blood returned to it, resulting in edema of body tissues is called

Contraction of skeletal muscles in the legs

A major factor in the return of venous blood from the legs is

dilate

A significant increase in carbon dioxide concentration within a muscle will cause the arterioles serving that muscle to

bradycardia

A slow heart rate of less than 60 beats per minute is known as

Cardiac muscle tissue

The type of muscle tissue forming the heart muscle is

increase

An abnormal increase in RBC's or plasma proteins is likely to cause the blood pressure to

ventricle to an atrium

An atrioventricular valve prevents the flow of blood from a/an

pulmonary veins

The veins carrying oxygenated blood to the heart are the

deoxygenated

Blood returning to the right atrium is

Atrioventricular valves

Chordae tendineae anchor the cusps of

hypertension

Chronic high blood pressure is known as

semilunar valves

During ventricular systole, the open heart valves are the

sinoatrial node

Impulses that initiate heart contraction are spontaneously formed in the

thrombophlebitis

Inflammation of a vein that is complicated by the formation of a blood clot is called

pericarditis

Inflammation of the sac enveloping the heart is called

ystolic/diastolic blood pressures

Normal systemic blood pressure is often expressed as 120/80 mm of Hg. These numbers express

Aorta/capillaries

Systemic blood flow is fastest/slowest in these vessels:

Contraction of the left ventricle

Systemic blood pressure is generated by

aneurysm.

The ballooning of a portion of an artery because of a weak spot in its wall is called a/an:

medulla oblongata

The center controlling the diameter of arterioles is located in the

systole

The contraction phase of the cardiac cycle is

Both aorta - brachiocephalic - right common carotid - right internal carotid and aorta - left common carotid - left internal carotid

The correct sequence of arteries carrying blood to the brain is

**NOT**** internal jugular - subclavian - superior vena cava - right atrium.

The correct sequence of veins returning most of the blood from the brain is

heart - arteries - capillaries - veins - heart

The correct sequence of vessels in the flow of blood is:

myocardial infarction

The death of a portion of the heart muscle due to an obstruction of a coronary artery is called

Parietal pericardium and an outer fibrous pericardium

The double-layered, loosely fitting sac around the heart is formed of an inner

closure of the atrioventricular valves

The first heart sound of the cardiac cycle is produced by

allow the flow of blood when the tissues are in need of oxygen

The function of precapillary sphincters is to

left atrium

The heart chamber receiving oxygenated blood from returning veins is the

medulla oblongata

The heart rate control center is located in the

aorta

The left ventricle pumps blood directly into the

smooth muscle

The middle layer of the wall of arteries and veins is composed of

QRS wave

The portion of an electrocardiogram that is formed by depolarization of the ventricles is the

systemic circuit

The portion of the circulatory system carrying oxygenated blood to body tissues and returning deoxygenated blood to the heart is the

the lungs only.

The pulmonary circuit carries blood to

atherosclerosis

The reduction in diameter of the lumen of an artery due to formation of fatty deposits in its wall is called

decrease

The release of acetylcholine by neurons in the pacemaker of the heart causes the heart rate to

***NOT** venae cavae

The right atrium receives blood directly from the

myocardium

The thickest layer of the heart wall is the
