100

Lowest possible grade necessary on final exams to pass

What is 70%

100

Number of years of paramedic experience necessary to qualify for the TNKase class

What is a minimum of 2 years

100

Medication that dilates both arteries and veins, but is much more efficient in veins

What is nitroglycerin

100

Number of questions on the final exam

What is 80

200

Partial Pressure of Oxygen in inspired air.

What is 160 mmHg.

200

Facilitates the diffusion of respiratory gases across the alveolar membrane

What is the difference in the partial pressure of gases/diffusion

200

Nitroglycerine works by dilating vessels, allowing more blood flow around occlusions and this equally important function.

What is decreases preload.

200

The inner most layer of Pericardium

What is visceral pericardium

200

This artery runs just inferior to the left atria and continues around to posterior side of the heart

What is the circumflex coronary artery

300

The thickest layer of heart tissue

What is the myocardium

300

Holds the atrioventricular valves closed during asystole

What is chordae tendinae 

300

States that the total pressure of a mixture of gases is the sum of each gases partial pressure. 

What is Dalton's Law

300

Partial pressure of oxygen in the alveolus

What is 160mm Hg

300

Tissue that lines the interior walls of atria 

What is pectinate muscle

Neurotransmitter released by the cardioacceleratory center; must jump gap junctions to reach target tissue

What is norepinephrine

400

Partial pressure of CO2 in the alveolus

What is 30mm Hg

400

Patrial pressure of Oxygen in respiratory arterioles.

What is 40 mmHg

Heart valve that is subject to the highest pressure

What is the bicuspid valve

500

Nervous  system that connects the cardioaccerlatory medulla to the heart

What is the sympathetic nervous system

500

Neurotransmitter released by the cardioinhibitory center; must cross gap junctions to effect target tissue

What is acetylcholine

500

Medication that takes up receptor sites on pacemaker cells; compliments the cardioacceleratory role

What is atropine

500

Hormone released by the cardioaccelratory center; interacts with specialized cells in the heart

What is epinephrine
