Chapter 7 - Ventilation, Perfusion, and Shock: Understanding Pathophysiology Flashcards
The process of converting glucose and other nutrients into the form of ATP is called:
metabolism.
Important chemicals in the body that separate into charged particles when dissolved in water are called:
electrolytes.
The process of metabolism that uses oxygen is called:
aerobic metabolism.
The fraction of the concentration of oxygen in the air that people breathe is called:
FiO2
An airway that is open to allow air to move in and out is called:
patent.
The volume of air that is moved in and out during one breathing cycle is called:
tidal volume.
The air inside the space between the mouth and the lungs is called the:
dead air space.
Specific receptors in the brain and vessels that register oxygen and carbon dioxide levels are called:
chemoreceptors.
The force exerted by proteins in the blood that tends to attract water away from the area around the body cells and pulls it toward the bloodstream is called:
plasma oncotic pressure.
Pressure created inside the blood vessels that pushes fluid out of the vessels is called:
hydrostatic pressure.
Specialized cells that measure the pressure inside blood vessels are called:
stretch receptors.
The amount of blood that returns to the heart prior to contraction is called:
preload.
The amount of blood moved by the heart in one minute is called:
cardiac output.
Hypoperfusion is another name for:
shock.
An exaggerated response by the immune system to a particular substance is called:
hypersensitivity.
