Heart Structure
This chamber has the thickest muscular wall.
What is the left ventricle?
The first audible sound heard when releasing a BP cuff.
What is systolic pressure?
DOUBLE JEOPARDY: Electrical conduction begins in this node.
What is the SA node?
Gas exchange occurs in these structures.
What are alveoli?
Air breathed in and out normally.
What is tidal volume?
Blood leaving the right side of the heart and traveling to the lungs is part of this loop.
What is the pulmonary loop?
In a BP reading of 154/86, this number represents systolic pressure.
What is 154?
This EKG wave represents ventricular depolarization.
What is the QRS complex?
DOUBLE JEOPARDY: Pulling the balloon upward in the bottle lung model causes this.
What is increased pressure, air leaves?
TV + IRV + ERV equals this lung measurement.
What is vital capacity?
DOUBLE JEOPARDY: During a Maniken build, this vessel should connect to the right ventricle.
What is the pulmonary artery?
Ankle systolic = 90, Brachial systolic = 100.
ABI equals this value.
What is 0.90?
This wave represents ventricular repolarization.
What is the T wave?
Fluid filling the alveoli causes this effect.
What is decreased gas exchange efficiency?
A prolonged, slow exhalation curve suggests this type of condition.
What is obstructive airway disease?
This type of muscle is involuntary but striated.
What is cardiac muscle?
DOUBLE JEOPARDY: An ABI of 0.60 suggests this condition.
What is peripheral artery disease?
Irregular spacing between QRS complexes suggests this condition.
What is arrhythmia?
Oxygen-rich blood returns to this chamber from the lungs.
What is the left atrium?
A pulse oximeter reading of 85% indicates this.
What is hypoxia?
This chamber pumps oxygen-rich blood to the body.
What is the left ventricle?
A 5-second strip shows 6 QRS complexes.
Heart rate equals this.
What is 72 beats per minute?
If the AV node fails, this process is disrupted.
What is ventricular contraction timing?
This structure connects the trachea to smaller bronchioles.
What are bronchi?
DOUBLE JEOPARDY: At high altitude, oxygen feels reduced because of this.
What is lower air pressure reducing oxygen density?
