1. allergic reaction

a. a substance made by the body; released in anaphylaxis

1. leukotrienes

b. a harsh, high - pitched inspiratory sound, usually resulting from upper airway obstruction

1. wheezing

c. a raised, swollen area on the skin resulting from an insect bite or allergic reaction

1. urticaria

d. an exaggerated immune response to any substance

1. stridor

e. raised areas on the skin that itch or burn, sometimes called hives

1. allergen

f. a poison or harmful substance

1. wheal

g. a substance that causes an allergic reaction

1. toxin

h. high - pitched, whistling breath sound usually resulting from bron - chospasm or bronchoconstriction, usually heard on exhalation

Explanation:

Step1: Match 1. Allergic reaction

An allergic reaction is an exaggerated immune response to any substance. So 1 - D.

Step2: Match 2. Leukotrienes

Leukotrienes are substances made by the body; released in anaphylaxis. So 2 - A.

Step3: Match 3. Wheezing

Wheezing is a high - pitched, whistling breath sound usually resulting from bron - chospasm or bronchoconstriction, usually heard on exhalation. So 3 - H.

Step4: Match 4. Urticaria

Urticaria are raised areas on the skin that itch or burn, sometimes called hives. So 4 - E.

Step5: Match 5. Stridor

Stridor is a harsh, high - pitched inspiratory sound, usually resulting from upper airway obstruction. So 5 - B.

Step6: Match 6. Allergen

An allergen is a substance that causes an allergic reaction. So 6 - C.

Step7: Match 7. Wheal

A wheal is a raised, swollen area on the skin resulting from an insect bite or allergic reaction. So 7 - C (Wait, no. Wait, correct: A wheal is a raised, swollen area on the skin resulting from an insect bite or allergic reaction. So 7 - C. Wait no, let's re - check. The description for C is “A raised, swollen area on the skin resulting from an insect bite or allergic reaction” which matches wheal. So 7 - C. And allergen (6) is “A substance that causes an allergic reaction” which is F? No, wait the options: F is “A poison or harmful substance” (toxin). C is for wheal.

Step8: Match 8. Toxin

A toxin is a poison or harmful substance. So 8 - F.

Answer:

1 - D, 2 - A, 3 - H, 4 - E, 5 - B, 6 - G (Wait no. Wait the options: G is not used. Wait re - check:

1. Allergic reaction - D (exaggerated immune response)
2. Leukotrienes - A (substance made by body in anaphylaxis)
3. Wheezing - H (high - pitched whistling on exhalation)
4. Urticaria - E (raised itchy areas called hives)
5. Stridor - B (harsh high - pitched inspiratory)
6. Allergen - G? No, wait the options: G is “A substance that causes an allergic reaction” which is allergen. So 6 - G.
7. Wheal - C (raised swollen area from insect bite/allergic)
8. Toxin - F (poison/harmful)

So final answer:

1. D
2. A
3. H
4. E
5. B
6. G
7. C
8. F
