Chapter 6 Flashcards
The amount of blood ejected from the heart in one contraction
Stroke volume
The amount of blood injected from the heart in one minute
Cardiac output
A substance that when dissolved in water separates into charged particles
Electrolyte
Fraction of inspired oxygen; the concentration of oxygen in the air we breathe
FiO2
The volume of air moved in a minute by the lungs
Minute volume
Swelling associated with the movement of water into the interstitial Space
Edema
And abnormally low amount of water in the body
Dehydration
And exaggerated response by the immune system to a particular substance
Hypersensitivity
The constant supply of oxygen and nutrients to the cells by the flow of blood
Perfusion
The study of how disease processes affect the function of the body
Pathophysiology
The push of water out of the bloodstream as a result of the pressure within the vassal
Hydrostatic pressure
Sensors in the blood vessels designed to identify internal pressure
Stretch receptors
The pressure in the per referral blood vassals that the heart must overcome to pump blood
Systemic vascular resistance
The volume of air moved in or out during one cycle of breathing
Tidal volume
Open, clear, and free from obstruction
Patent
Here that occupies the space between the mouth and I’ll they’ll lie but does not actually reach the area of gas exchange
Dead airspace
The cellular function of converting nutrients to energy necessary for cell function
Metabolism
Chemical sensors in the brain and blood vessels that identified changing levels of oxygen and carbon dioxide
Chemoreceptors
The pull exerted on water in and around the body cells into the bloodstream by large proteins in the plasma portion of the blood
Plasma oncotic pressure
Ventilation/perfusion match
V/Q match
A ventilation/perfusion match or a V/Q match requires what two things?
Enough air for alveoli and enough blood in capillaries
Shock is commonly defined as:
Poor perfusion
