Question

question 25
1 pts
the localized pressure gradient needed to maintain blood flow in a tissue is called
regional pressure.
perfusion pressure.
systolic pressure.
diastolic pressure.
question 26
1 pts
the difference between systolic pressure and diastolic pressure is called
korotkoff sounds.
minute volume.
pulse pressure.
pressure gradient.
question 27
1 pts
the term used to describe the collection of mechanisms that influence the circulation of blood is:
hematopoiesis.
hemodynamics.
hemostasis.
hematocrit.

Explanation:

• Question 25: Perfusion pressure is the localized pressure gradient required to maintain blood flow in a tissue. Regional pressure is a more general term. Systolic pressure is the pressure when the heart contracts, and diastolic pressure is when the heart relaxes.
• Question 26: Pulse pressure is calculated as systolic pressure - diastolic pressure. Korotkoff sounds are the sounds heard when measuring blood pressure. Minute volume is related to respiratory volume (tidal volume × respiratory rate). Pressure gradient is a more general term for a difference in pressure over a distance.
• Question 27: Hemodynamics is the study of the forces and mechanisms influencing blood circulation. Hematopoiesis is blood cell formation. Hemostasis is the process of stopping bleeding. Hematocrit is the percentage of red blood cells in the blood.

Answer:

• Question 25: perfusion pressure.
• Question 26: pulse pressure.
• Question 27: hemodynamics.
