QuestionAnswer
EXTERNAL INTERCOSTAL MUSCLE it increases the AP chest diameter during inspiration.
INTERNAL INTERCOSTAL MUSCLE It decrease the lateral diameter during expiration.
DIVISION OF THE INTERIOR CHEST Right pleural cavity Left pleural cavity mediastinum
How does blood get oxygenated Ventilation, perfusion, transportation of respiratory gases.
Cardiac action potential It is a series of events that causes the electrical charge inside the cell to change from it's resting state to it's depolarized state.
ECG It is a graphic recording of electrical activity during the cardiac cycle. It records electrical current generated by movement of ions in and out of the myocardial cell membrane.
Normal sinus rate It indicates or implies that the impulse originate at the SA node and follows the normal sequence through the conduction system.
Ventilation It is the process of moving gasses into and out of the lungs.
cardiopulmonar physiology it involves the delivery of deoxygenated blood to the right side of the heart.
Oxygenation of blood Blood is oxygenated through ventilation, perfusion, transportation of respiratory gases.
events that alter the circulation of blood hemorrhage, dehydration causes increase in circulating blood and decrease in stroke volume.
coronary artery circulation it supplies the myocardium with Oxygen and nutrients and removes waste. the left coronary artery supplies the left ventricular myocardium.
systemic circulation it delivers oxygen, nutrients, and remove waste from tissues
cardiac output it is the amount of blood ejected from the left ventricle each minute. normal is 4-6L/min
surfactant it si a chemical produced in the lungs to maintain the surface tension of the alveoli and keep them from collapsing.
airway resistance it is teh pressure difference between the mouth and the alveoli in relation to the rate of flow of inspired gas.
events that lead to increase airway resistance airway obstruction, asthma, tracheal edema,
dysrhythemia it is a deviation from the normal sinus heart rhythm.
diffusion it is the process for the exchange of respiratory gases in the alveoli and capillary of the body tissues.
compliance it is the ability of the lungs to distend or to increase intra-aveolar pressure.
Tidal volume it is the amount of air exhaled in a normal breath and is assumed to equate with the amount of air inhaled with each minute.
Atria contractions the atrioventricular valves open to allow blood into the ventricles.
ventricular contractions it closes atrioventricualar valves and opens the semilunar valves to allow blood to the lungs and the rest of the body.
myocardial ischemia it results when the supply of blood to the myocardium from coronary arteries is insufficient to meet myocardial oxygen demands.
pulmonary circulation its primary function is to move blood to and from the alveolar capillary membrane for gas exchange it also act as a filter removing small thrombi before they reach the vital organs.
cardiac action potential it is a series of events that cause the electrical charge inside the cell to change from its resting state to its depolarized state and back tot eh resting state.
what causes hypoxia decrease hemoglobin, decrease in concentration of inspired oxygen, tissues inability to extract oxygen from blood, decrease in diffusion of oxygen from alveoli to the blood, poor tissue perfusion, impaired ventilation.
what causes alterations in cardiac function illness, alterations in cardiac rhythm, strength of contraction, blood flow through chambers, myocardial blood flow, peripheral circulation
myocardial infarction it results from sudden decrease in coronary blood flow or an increase in myocardial oxygen demand without adequate coronary perfusion.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
