Pulse
"A-V" valve means....
Atrioventricular
The thick vertical wall that divides the left chambers of the heart from the right chambers is known as....
Septum
At the end of the smallest bronchial tubes are microscopic air sacs that make up the tissue of the lungs. These air sacs are known as...
Alveoli
Put in order the correct sequence of structures that an oxygen molecule passes through in order to oxygenate the blood at the capillary where gas exchange occurs in each lung:
Alveolus, Bronchiole, Bronchus, Glottis, Larynx, Pharynx, and Trachea
1) Pharynx (throat, where oral and nasal cavity connect)
2) Glottis [make sure the epiglottis is open]
3) Larynx
4) Trachea
5) Bronchus
6) Bronchiole
7) Alveolus

Lungs
Bonus: Chest
What is the difference between pulmonary circulation and systemic circulation?
Pulmonary circulation relates to the blood flow between heart and lungs, whereas systemic circulation refers to the blood flow through all parts of body except the lungs.
The valve that separates the right atrium from the right ventricle is known as the _____________ valve.
(Bonus: The valve that separates the left atrium from the left ventricle is known as the ____________ valve.)

Larynx
Blood that is passing through the pulmonary valve is leaving which chamber of the heart?
A) Left atrium B) Left ventricle
C) Right atrium D) Right ventricle
D) Right ventricle
Blood pressure is measured by ____________ over ________________.
BONUS: Which of the following is an example of an average healthy blood pressure measurement:
A) 160/50 B) 90/120 C) 110/70 D) 140/90
Bonus: C
It is from the left ventricle that recently oxygenated blood is forcefully pumped through the aorta into the rest of the entire body (It has to be strong to both exert that pressure and sustain the force!)
