100

Working with 1-way valves, SNS signals a need to get blood back to the heart. 

What is Venoconstriction?

200

Being in this position leads to a more even distribution of blood and therefore greater stroke volume. 

What is horizontal?

300

During inspiration, the diaphragm decreases the pressure in this cavity drawing air into the lungs. 

What is the thoracic / chest cavity?

400

Aerobic exercise leads to greater stroke volume by increasing __________.

What is Blood Volume?

500

To increase stroke volume, you rely on _______ more during rest and _______ more during exercise. 

What are venoconstriction and the muscle pump. 

The Oxyhemoglobin Dissociation Curve (Bohr-ing!!!)

100

RBCs remain mostly saturated with O₂ here. 

What is arterial blood? 

200

The PO₂ is 40 mmHg here. 

Where is the muscle?

300

I hang onto O₂ until I can't anymore (generally 15-20 mmHg). 

What is myoglobin? 

400

Muscular contractions generate heat which causes more ___________.

What is O₂ unloading from Hb?

500

During exercise, I'll cause a lower O₂ saturation at an equal PO₂ due to the hydrogen ions I'm carrying. 

What is Lactate (or lactic acid)? 

Nate Dogg and Warren G gonna what?

100

I am the word for detection of increased ADP, CO2, and Temperature. 

What is autoregulation?

200

This is the result of nitric oxide release from shear stress along the blood vessel walls. 

What is Vasodilation?

300

If PCO2 reaches 50 mmHg, this happens.

What is taking a breath?

400

I detect pressure in the carotid artery and slow heart rate when pressures are too high. 

What are baroreceptors?

500

I send messages to the brain regarding stretch and tension in muscles. 

What are the mechanoreceptors?

Pump up the Lung Volumes

100

TV, VC, RV, and TLV are all examples of this type of volumetric measure. 

What is Static Volume?

200

I am the maximal amount of air that can be expired following a maximal inhalation. 

What is Vital Capacity?

300

I am the result of multiplying tidal volume (TV) and breathing frequency (BF). 

What is Minute Ventilation (Ve)?

400

I am the amount of air left in the lungs after all other air has been expired. 

What is Residual Volume?

500

I'm the result of the following equation:

(TV - ADS) x BF

What is Alveolar Ventilation?

Jargon and Idioms

100

This is the product of cardiac output and total peripheral resistance.

What is Blood Pressure?

200

This is the relaxation of the heart.

What is Diastole?

300

This is the pressure each gas in a mixture exerts independently.

What is Partial Pressure?

400

This is the collective name given to structures of the conducting zone. 

What is Anatomical Dead Space?

500

I make things slippery instead of sticky.

What is Surfactant?
