What is the vagus nerve? - ANSWERS-The vagus nerve is the 10th
cranial nerve. It's supplies parasympathetic innervation to the heart.
Stimulation of the vagus nerve will do what? - ANSWERS-Slow the
heart rate.
When you have an excessive parasympathetic stimulation of the vagus
nerve it can cause a sudden drop in what? - ANSWERS-Heart rate
(bradycardia) and blood pressure (hypotension)
What is it called if there's a decrease in the blood flowing to the brain
causing the patient to faint from excessive parasympathetic stimulation
of the vagus nerve? - ANSWERS-Vasovagal syncope
what can vasovagal syncope be triggered by? - ANSWERS-Sight of
blood, or extreme stress, standing in place for long periods of time, heat
exposure, straining. Episodes usually Last less than a minute and resolve
without treatment.
What type of drug is atropine? - ANSWERS-Parasympatholytic drug
(counters the effects of the parasympathetic system.

The heart is divided into four chambers, the two upper chambers are the?
- ANSWERS-Atria/atrium
The heart is divided into four chambers, the two lower chambers are the?
- ANSWERS-Ventricles
The tricuspid valve is located where? - ANSWERS-Between the right
atrium and the right ventricle
The mitral valve is located where? - ANSWERS-between left atrium and
left ventricle
The pulmonic valve lies in the what? - ANSWERS-Pulmonary artery
The aortic valve lies in the what? - ANSWERS-The Aorta
What is the function of the heart? - ANSWERS-The heart is the most
powerful muscle in the body, which pumps blood through blood vessels
to provide the body with oxygen.

How does the heart pump in an atrial contraction? - ANSWERS-The
atria squeezes the blood into the ventricles. Tricuspid and mitral valves
open. Aortic and pulmonic valves close.
How does the heart pump in ventricular contraction? - ANSWERS-Both
ventricles are filled with blood. Ventricles squeeze blood into the
pulmonary artery and the aorta, pulmonic and aortic valves open,
tricuspid and mitral valves close.
What's the pathway of blood through the heart on the right side? -
ANSWERS-Superior and inferior vena cava, right atrium, tricuspid
valve, right ventricle, pulmonic valve, pulmonary artery, to the lungs.
What's the pathway of blood through the heart on the left side? -
ANSWERS-Pulmonary vein, left atrium, mitral valve, left ventricle,
aortic valve, aorta to the rest of the body
Superior and inferior Venna cava bring deoxygenated blood from
where? - ANSWERS-From the body to the right atrium
The pulmonary artery takes deoxygenated blood from where? -
ANSWERS-From the right ventricle to the lungs.

The pulmonary vein takes newly oxygenated blood from where? -
ANSWERS-From the lungs to the left atrium.
The aorta takes oxygenated blood from where? - ANSWERS-From the
left ventricle to the rest of the body.
How do arteries and veins connect? - ANSWERS-They connect through
the capillary
They connect through the capillary - ANSWERS-
What happens in a capillary? - ANSWERS-As the blood moves,
octogenarian is dropped off and carbon dioxide is picked up.
What happens when the blood moves through capillaries in the lungs? -
ANSWERS-Pick up oxygen and drops of carbon dioxide.
What is aortic stenosis? - ANSWERS-Aortic valve is "stiff"
