Ventricular depolarization c. Atrial repolarization d. Ventricular repolarization 18. You wo to precede the uld expect the ventricular contraction signal from the ventricular contraction signal from the a. Finger pulse transducer /ECCG b. ECG /finger pulse transducer 19. The pressure that it ventricle is larger due to the generate. a. Right / high b. Left / high c. Right low d. Left / low 20. The base unit of the lung that is responsible for gas exchange is called a. Alveoli b. Bronchiole c. Tertiary bronchus air volume within the lungs. 21. Contraction of the diaphragm a. Increases b. Decreases c. No change 22. When you exhale there is no remaining gas within your lungs. a. True b. False your your heart rate whereas breathing out 23. Breathing in a. Decreases / increases b. Increases / decreasesExplanation / Answer
15. b. oxygenated/ deoxygenated.
Oxygenated blood from the lungs enter left atrium and deoxygenated blood from the body enters right atrium.
16. b. False.
The two atrium contract simultaneously, and when they relax, the two ventricles contract simultaneously.
17. b. ventricular depolarization.
QRS complex in ECG occurs due to depolarization of the ventricles and is the phase when ventricles begin to contract.
19. b. Left / high
The left ventricle is larger due to the high pressure that it is required to generate.
The left ventricle needs to generate high pressure as the blood from it circulates to the whole body.
