100
The firing of the sinoatrial node signals this wave on an ECG
P-Wave (Atrial Depolarization)
100
This type of nervous input constricts the coronary arteries
Parasympathetic
100
Oxygenated blood is carried back to this chamber of the heart
left atrium
100
The process of "Respiration" refers to these 3 processes
Ventilation, Gas Exchange, Oxygen Use
100
Air in the pleural cavity causes this
Pneumothorax
200
The QRS wave on an ECG signifies this
Ventricular Depolarization (and atrial repolarization)
200
This type of artery conducts large volumes of blood away from the heart
Elastic Artery (conducting artery)
200
The systemic circuit begins in this chamber of the heart
left ventricle
200
Both fluid, air, and food pass through this part of the pharynx
Oropharynx
200
Forced exhalation relies on these muscles
abdominals and interosseous part of the internal intercostals
300
After the AV node, electric signals are sent here
Bundle of His
300
This type of capillary is found in the liver and spleen to allow for greatest amounts of diffusion
Sinusoid (Discontinuous)
300
For blood to flow from the right atrium to the right ventricle, it must pass through this valve
tricuspid valve
300
Type II Alveolar Cells secrete this
Surfactant
300
The covering of the lungs is called
Visceral pleura
400
Parasympathetic input to the heart comes from this nerve
Vagus
400
These blood vessels have valves to prevent backflow
Veins
400
In order to open heart valves, this structure must pull on the cusps of the valves
chordae tendinae
400
Inhalation happens when air pressure in the lungs is ______ than the atmospheric pressure, causing an _______ in thoracic diameter
lower; increase
400
Cardiac pain is referred to the left side of the body at these vertebral levels
T1-T4
500
This part of the ECG is for ventricular FILLING
PR Interval
500
If an artery is cut, this happens in a vein
Vasoconstriction to conserve blood volume
500
When blood pressure is low, this receptor is triggered to cause vasoconstriction
Baroreceptors
500
The muscles responsible for RELAXED inhalation are
diaphragm, external intercostals, and interchondral part of internal intercostals
500
The primary bronchi divide into these branches
superior, intermediate (on right), inferior lobar bronchi
