Heart & Blood Flow
The heart has this many chambers and this many valves.
What are four chambers and four valves?
The highest pressure reached during ventricular contraction.
What is systolic?
This is the delivery of blood, oxygen, and nutrients to the body’s tissues.
What is perfusion?
These are the three types of blood vessels.
What are arteries, veins, and capillaries?
This structure is known as the heart’s pacemaker.
What is the SA (sinoatrial) node?
This is a normal blood pressure.
What is 120/80 mmHg?
The three P’s of perfusion are the pump, the pipes, and this.
What is plasma (blood volume)?
These thick, muscular vessels carry blood away from the heart under high pressure.
What are arteries?
The tricuspid valve sits between these two chambers.
What are the right atrium (RA) and right ventricle (RV)?
Fast heart rate, stable blood pressure, mild disorientation, and pale, sweaty skin, in a patient who is getting worse.
What is compensated shock?
In this type of shock, the body is still keeping blood pressure stable by speeding up the heart rate and constricting vessels.
What is compensated shock?
These tiny vessels are where oxygen and nutrients are exchanged with the tissues.
What are capillaries?
This chamber has the thickest myocardium because it pumps blood to the entire body.
What is the left ventricle?
On an ECG, the P wave shows this event.
What is atrial contraction?
In this type of shock, blood pressure drops and the body can no longer make up for it.
What is decompensated shock?
These vessels are able to dilate and constrict to change blood flow.
What are arteries?
Name all four heart valves.
What are the tricuspid, pulmonary, bicuspid (mitral), and aortic valves? (30 seconds)
The QRS complex shows this event.
What is ventricular contraction?
Vessel diameter, cardiac contraction strength, and blood volume all affect this.
What is perfusion?
Blood gets from the feet back to the heart against gravity thanks to these two things working together. (20 seconds)
What are one-way valves in the veins and squeezing from skeletal muscles?
