suddenly.
B.Medication derived from pit viper venom works to lower high blood pressure.
C. Pit viper venom blocks the production of a hormone involved in the regulation

Answer 1

B

Step-by-step explanation:

The discovery that the venom of the Brazilian pit viper, which causes a massive decrease in arterial pressure, works by inhibition of angiotensin-converting enzyme (ACE) led to the development of synthetic, orally administered ACEIs.

This viper venom drug is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension [83]. Currently, several venom-based drugs are being developed; for example, a pain-reliever.
