Question

which pressure is measured when the heart is relaxed?
diastolic
systolic
stenotic
intercalated
question 24
choose the root that means protection; safeguard.
phoresis
palpita
phylaxis
petechia

Explanation:

• Diastolic pressure: When the heart relaxes between beats (diastole), the pressure in the arteries is measured as diastolic pressure.
• Systolic pressure: This is the pressure when the heart contracts (systole), not when it's relaxed.
• Stenotic: Refers to a narrowing (like in a blood vessel or heart valve), not a pressure measurement related to heart relaxation.
• Intercalated: In the heart context, intercalated discs are structures between cardiac muscle cells, not a pressure term.

For the second question:

• Phylaxis: The root “phylaxis” means protection or safeguard.
• Phoresis: Generally means “carrying” (e.g., in medical terms like “electrophoresis” - carrying with electricity).
• Palpita: Related to “palpitate” (heart beating rapidly or irregularly).
• Petechia: Refers to small red or purple spots on the skin (due to bleeding).

Answer:

First question: diastolic
Second question: phylaxis
