Question 32

Step1: Recall human blood volume

The average adult human body contains about 5 to 6 quarts (or 4.7 to 5.7 liters) of blood. Option a is 5 - 7 pints (too low, as 1 quart = 2 pints, so 5 quarts = 10 pints), option b is 8 - 10 pints (close but typically 5 - 6 quarts which is 10 - 12 pints? Wait, no, correction: average blood volume is about 4.5 to 5.5 liters, which is about 4.7 to 5.8 quarts, or 9 to 12 pints. Wait, maybe the options are different. Wait the options: a. 5 - 7 pints, b. 8 - 10 pints, c. 3 - 4 quarts, d. 5 - 6 quarts. Let's convert: 1 quart = 2 pints. So 5 quarts = 10 pints, 6 quarts = 12 pints. The average blood volume is about 8 - 10 pints (4 - 5 liters) for adults? Wait, maybe the question is for "what" human body, maybe a typo. Wait, maybe the correct answer is d. 5 - 6 quarts? Wait no, let's check: typical blood volume is 4.5 - 5.5 liters, which is 4.7 - 5.8 quarts, so 5 - 6 quarts is close. But 8 - 10 pints is 4 - 5 quarts (since 8 pints = 4 quarts, 10 pints = 5 quarts). So maybe the answer is d. 5 - 6 quarts? Wait, maybe I made a mistake. Let's recheck: adult blood volume is approximately 5 liters, which is about 5.28 quarts (since 1 liter = 1.057 quarts). So 5 - 6 quarts is correct. So the answer is d. 5 to 6 quarts.

Step2: Match with options

Option d is 5 to 6 quarts, which is the correct range for blood volume in the adult human body.

Step1: Define "integument"

The term "integument" refers to a natural covering, like the skin (integumentary system). Option a: hormone - no, hormones are chemical messengers. Option b: bone marrow - no, that's part of the bone. Option c: natural covering - yes, that's the definition of integument. Option d: gland - no, glands secrete substances.

Step2: Select the correct option

So the correct answer is c. natural covering.

Step1: Recall skin nerve density

One square centimeter of skin contains about 3 yards of nerves. Option a: 12 - too high, option b: 3 - correct, option c: 4 - no, option d: 10 - no.

Step2: Choose the correct option

So the answer is b. 3.

Answer:

d. 5 to 6 quarts
