Q: Which formula best represents the calculation of body mass index (BMI), a measure often used to assess adipose tissue distribution?

$$\text{BMI} = \frac{\text{weight (kg)}}{\text{height (m)}^2}$$

Question 1

Which type of epithelial tissue is best suited for rapid diffusion of gases in the alveoli of the lungs?

Accepted Answer

Simple squamous epithelia

Question 2

A patient presents with a burn that destroys the epidermis and exposes the underlying tissue. Which epithelial tissue is most likely damaged, and what is its primary function?

Accepted Answer

Stratified squamous epithelia; protection against abrasion

Question 3

Which glandular secretion mechanism involves the entire cell rupturing to release its contents?

Accepted Answer

Holocrine secretion

Question 4

Transitional epithelia are uniquely suited for which organ, and why?

Accepted Answer

Urinary bladder; because they stretch and recoil

Question 5

Which connective tissue type is characterized by parallel bundles of collagen fibers and is found in tendons?

Accepted Answer

Dense regular collagenous connective tissue

Question 6

A biopsy reveals tissue with chondrocytes in lacunae and a glassy matrix. Which type of cartilage is this, and what is its primary function?

Accepted Answer

Hyaline cartilage; support with some flexibility

Question 7

Which formula best represents the calculation of body mass index (BMI), a measure often used to assess adipose tissue distribution?

Accepted Answer

$$	ext{BMI} = \frac{	ext{weight (kg)}}{	ext{height (m)}^2}$$

Question 8

Which connective tissue is most abundant in the dermis of the skin and provides resistance to multidirectional stress?

Accepted Answer

Dense irregular connective tissue

Question 9

A patient with a genetic disorder affecting elastic fibers would most likely have problems in which connective tissue type?

Accepted Answer

Dense regular elastic connective tissue

Question 10

Which muscle tissue type is responsible for voluntary movements and is characterized by multinucleated, parallel fibers?

Accepted Answer

Skeletal muscle tissue

Question 11

Cardiac muscle tissue is unique because it contains intercalated discs. What is the primary function of these structures?

Accepted Answer

To allow rapid communication and synchronized contraction

Question 12

Which tissue type is responsible for transmitting electrical impulses throughout the body?

Accepted Answer

Nervous tissue

Question 13

A patient with a deficiency in vitamin D is likely to have issues with which specialized connective tissue, and why?

Accepted Answer

Bone; because vitamin D is required for calcium absorption

Question 14

Which of the following best describes the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream; exocrine glands secrete products into ducts

Question 15

Which scenario best illustrates the function of pseudostratified columnar epithelia?

Accepted Answer

Movement of mucus in the respiratory tract

Question 16

A patient is diagnosed with a disorder affecting the reticular tissue. Which organ is most likely to be impacted?

Accepted Answer

Liver

Question 17

Which formula would you use to calculate the total surface area ($$A) of a $$simple squamous epithelial layer covering a rectangular organ with length $$l$$ and width $$w$$?

Accepted Answer

$$A = l 	imes w$$

Question 18

Which muscle tissue type is found in the walls of hollow organs such as the intestines and is responsible for involuntary movements?

Accepted Answer

Smooth muscle tissue

Question 19

Which of the following best explains why stratified squamous keratinized epithelia are found in the skin?

Accepted Answer

They provide a waterproof barrier and protect against abrasion

Question 20

A patient with a blood disorder affecting erythrocytes is most likely to have issues with which specialized connective tissue, and what is its primary function?

Accepted Answer

Blood; transport of gases, nutrients, and wastes
