Tricuspid and mitral

What two valves make the semilunar valves?

• mitral and tricuspid

pulmonary and aortic

Valve Backflow prevention involves:

• coordinated open and close movement to keep blood flowing in one direction

• coordinated muscle contraction of only the atriums

• coordinate muscle contractions atriums and ventricles

• coordinated open and close movement of tricuspid and mitral valves only

coordinated open and close movement to keep path of blood flowing in one direction

Tricuspid and Mitral Valve closing functions to prevent back flow into the ___:

• ventricles

• atria

• atrium and ventricles

atria

what causes the pulmonary and aortic valves to close?

• when atria only relax and ventricles contract

• when ventricles relax and atria contract

• when atria and ventricles are relaxed AND when atria pumps blood into ventricles

• when atria and ventricles are contracted AND when atria pumps blood into ventricles

when atria and ventricles are relaxed AND when atria pumps blood into ventricles

The _____ is found in the right atrium

• pectinate muscle

• cord tedinae

• papillary muscles

• trabecular carneae

pectinate muscle

What are the three tissues of the right ventricle?

• cord tendinae, papillary muscles, trabecular carneae

• cord tendinae, papillary muscles, pectinate muscle

• pectinate muscle, cord tendinae, papillary muscles

cord tendinae, papillary muscles, trabecular carneae

the cordae tendinae attach to which valve:

• mitral valve by cartilaginous ligaments

• tricuspid valve by cartilaginous ligaments

• bicuspid valve by tendinous cords

• tricuspid by tendinous cords

tricuspid valve via tendinous cords

Which tissue in the right ventricle is described to connect the cord to the ventricle walls?

• cordae tendinae

• papillary muscles

• trabecular carneae

papillary muscles

Which part of the interior heart is mostly smooth muscle with small pectinate ridges:

• L-A

• L-V

L-A

True or false: the left ventricle has trabeculae carneae and papillary muscles, but no cordae tendinae

False: the left ventricle has trabeculae carneae, papillary muscles, and cordae teninae

Blood enters heart via _______ and leaves heart via _______

• ventricles ; atria

• atria ; ventricles

atria ; ventricles

Superior and Inferior Vena Cava bring blood to which heart chamber:

• left atrium

• right atrium

• left ventricle

• right ventricle

right atrium

Pulmonary veins bring blood into the:

• right atrium

• left atrium

• right ventricle

• left ventricle

left atrium

The right ventricle takes blood away via the :

• pulmonary trunk which splits into R-L pulmonary arteries

• aortic trunk which splits into R-L pulmonary arteries

• pulmonary trunk which split into veins

• aortic trunk which split into veins

pulmonary trunk which splits into R-L pulmonary arteries

Step 1 of Blood Path in Heart

De-oxygenated blood enters right

atrium via superior and inferior vena

cavae

Step 2 of Blood Path in Heart

De-oxygenated blood moves to right

ventricle when tricuspid valve opens**

Step 3 of Blood Path in Heart

Right ventricle pumps this

deoxygenated blood to left and right

pulmonary arteries when pulmonary

valve opens

Step 4 of Blood Path in Heart

Blood is oxygenated in the lungs via

gas exchange

Step 5 of Blood Path in Heart

Oxygenated blood returns to heart

via pulmonary veins

Step 6 of Blood Path in Heart

Oxygenated blood enters left

atrium

Step 7 of Blood Path in Heart

Oxygenated blood enters left

ventricle when mitral (bicuspid)

valve opens**

Step 8 of Blood Path in Heart

Left ventricle pumps oxygenated

blood into body via aorta when aortic

valve opens

Order of Blood Path through chambers of the heart:

• right atrium, right ventricle, lungs, pulmonary veins, left atrium, left ventricle

• left ventricle, left atrium, pulmonary veins, lungs, right ventricle, right atrium

• right ventricle, right atrium, pulmonary veins, lungs, left atrium, left ventricle

right atrium, right ventricle, lungs, pulmonary veins, left atrium, left ventricle
