Heart disease is?

The leading cause of death in the u.s.

1 in how many deaths are caused by deart disease?

1 in 4

Perfusion is the passage of ____1__ and ___2___ blood through the body to the cells and the removal of cellular __3__ products. Select the fill in the blanks in order 1-3.

Nutrients, Oxygenated, Waste

Perfusion depends on the ___1___ functions of the ___2___ and __3__ systems. Select the fill in the blanks in order

Normal, Respiratory, Cardiac

The Superior and inferior vena cava deliver blood where? (Picture is just for reference, will be with all anatomy and physiology type questions.

Right atrium

The blood then travels through which valve?

Tricuspid valve

The blood then enters the?

Right ventricle

Once in the right ventricle the blood enters which valve?

The pulmonic valve

Once in the pulmonic valve the blood enters where?

The pulmonic arch/pulmonary artery.

Once in the pulmonary artery what happens?

The artery splits into two, one going to each lung

The blood then enters the?

Lungs

Once the good is done exchanging Co2 for oxygen where does the blood go?

Through the pulmonary veins

Once the blood is in the pulmonary veins where does the blood go?

The left atrium

Once the blood is in the left atrium where Les it go?

Through the bicuspid mitral/valve

Once through the bicuspid valve where does the blood go?

The left ventricle

Once the blood is in the left ventricle where does it go?

Through the semilunar/aortic valve

Once in the semilunar/ aortic valve where does the blood go?

The aortic arch through the aorta and out into the body

The left anterior descending artery is also known as?

The widow maker full blockage very bad!

The autonomic nervous system is made of two parts which are?

Sympathetic nervous system, Parasympathetic nervous system

The sympathetic nervous system does what?

Increases HR, Increase rate of conduction, increases contraction strength, Fight or flight response

The parasympathetic system does what?

Decreases HR, decreases conductivity, decreases contractility., Low and slow, Think para-paralyzed low and slow? idk

If preload is decreased what happens to the stroke volume (SV) and cardiac output (CO)?

SV decreases, CO decreases

If afterload increases what happens with the SV and CO?

Decreased SV, Decreased CO

If there is decreased contractility what happens with the SV and CO?

Decreased SV, Decreased CO

What are arteries?

A blood vessel that carries oxygenated blood from the heart to tissues and organs in the body.

What are veins?

A blood vessel that carries deoxygenated blood to the heart from tissues and organs in the body.

NOW NOTE THIS “RULE” IS SWITCHED WITH THE PULMONARY VEINS AND ARTERIES. Select the function of the pulmonary veins and the function of the pulmonary arteries.

The pulmonary arteries carry deoxygenated blood from the heart to the lungs to be oxygenated., The pulmonary veins bring that oxygenated blood back to the heart into the left atrium.

What are capillaries?

Any of the fine branching blood vessels that for a a network between the arterioles and venules.

What are lymphatics?

They are thinner than veins thicker than capillaries. They carry lymph or lymphatic fulid through out the body.

Blood flow is?

Regulates by the CNS, circulating hormones and chemicals to meet metabolic demands of tisssues.

Select the fill in the blanks in ORDER. Increased demand = vessels ___1__ to increase blood flow and __2__ blood pressure.

Dilate, Decrease

Select the fill in the blanks in ORDER. Decreased demand = vessels __1__ causing a(n) __2___ in B.P.

Vasoconstrict, Increase

What is diastole?

The phase of the cardiac cycle that consists of relaxation and filling of the atria and ventricles, usually about 2/3rds of the cardiac cycle

What is diastolic B.P.?

The amount of pressure or force against the arterial walls during the relaxation phase of the cardiac cycle, Think d, down, (bottom number of B.P.)

What is systole?

The phase of the cardiac cycle that consists of the contraction and emptying of the atria and ventricles.

What is systolic B.P.?

The amount of pressure or force generated by the left ventricle to distribute blood into the aorta with each contraction of the heart., S is the top number

True or false? The kidneys play a role in regulating BP.

True

Does the autonomic nervous system play a role in regulating BP?

Yes

The autonomic NS (nervous system) is comprised of what two parts? And there needs to be what between the two?

The sympathetic NS, The parasympathetic NS, Balance!

What does the sympathetic NS do?

Increase HR, Increase AV conduction, Increase contractility, Vasocontriction, Really gonna need memory trick to separate these two I always mix them up 😭🤣

What does the parasympathetic NS do?

Decrease HR, Decrease contractility, Decrease conductivity, Para- paralyzed slow? idk grasping at straws here 😭

What are Chemoreceptors in the heart do? And where are they?

They are in the aortic arch and carotid bodies., They are sensitive to hypoxemia.

Where are baroreceptors and what do they do?

In the aortic arch and carotid sinuses, Respond to an increase in BP

Where are stretch receptors and what do they do?

In the vena cava and right atrium, Sensitive to a decrease in volume
