Answer:

Explanation:

1. A technician extracts and

later purifies venom from the

species for which SCIENTISTS want

to make an antivenom.

2. A ranch hand injects a small,

harmless dose of venom

into a horse. The TOXINS in the

venom trigger the horse’s immune

system to produce antibodies that

neutralize those particular toxins.

3. Over the next year, the horse

receives several booster

shots with increasing amounts

of venom. Eventually, the horse

produces so many antibodies that

it’s immune to the venom.

4. A ranch hand draws blood

from the horse. A machine

extracts the plasma, the part of the

blood that contains the antibodies.

The REST of the blood is returned

to the horse.

5. The plasma is sent to a LAB,

where chemists purify it and

package it as a liquid or freeze dried

powder. It is then shipped in

vials to hospital pharmacies.

6. When a patient comes in with

a bite or sting, doctors use an

IV line to inject the antivenom into

the patient’s veins. The antibodies

circulate through the body and

neutralize the toxin molecules.
