Q: Which equation correctly represents the calculation of hematocrit, a measure of the proportion of red blood cells in blood?

$$\frac{\text{Volume of red blood cells}}{\text{Total blood volume}} \times 100$$

Q: Which of the following equations correctly calculates the total number of cells in a blood sample if the concentration is $$5 \times 10^6$ cells/mL and the sample volume is 2 mL?

$$5 \times 10^6$ \times 2 = 1 \times 10^7$ cells$

Question 1

Question 4

A patient presents with a burn injury that destroys the top layer of skin. Which tissue type is most likely affected?

Accepted Answer

Stratified squamous epithelial tissue

Question 5

Which of the following is a key difference between stratified squamous epithelial tissue and connective tissue - blood?

Accepted Answer

Stratified squamous epithelial tissue is avascular, while blood is highly vascular.

Question 6

Which of the following best explains why stratified squamous epithelial tissue is found lining the esophagus?

Accepted Answer

It resists mechanical stress and abrasion from food passage.

Question 7

A blood smear reveals an abnormally high number of neutrophils. What condition might this indicate?

Accepted Answer

Bacterial infection

Question 8

Which of the following equations correctly calculates the total number of cells in a blood sample if the concentration is $$5 	imes 10^6$ cells/mL and the sample volume is 2 mL?

Accepted Answer

$$5 	imes 10^6$ 	imes 2 = 1 	imes 10^7$ cells$

Question 9

Which of the following statements about the structure of stratified squamous epithelial tissue is correct?

Accepted Answer

It consists of multiple layers of flat cells, with the deepest cells being cuboidal or columnar.

Question 10

Which function is NOT associated with connective tissue - blood?

Accepted Answer

Protection against mechanical abrasion

Question 11

A biopsy of skin tissue reveals several layers of cells with flattened, anucleate cells at the surface. What is the most likely tissue type?

Accepted Answer

Stratified squamous epithelial tissue

Question 12

Which of the following is a major component of the extracellular matrix in blood?

Accepted Answer

Plasma

Question 13

If a patient has a reduced number of erythrocytes, which physiological process is most likely impaired?

Accepted Answer

Oxygen transport

Question 14

Which tissue type is most likely to regenerate rapidly after injury due to its high mitotic rate?

Accepted Answer

Stratified squamous epithelial tissue

Question 15

Which of the following best describes the arrangement of cells in blood connective tissue?

Accepted Answer

Cells are suspended in a liquid matrix called plasma.

Question 16

Which of the following is a real-world consequence of damage to stratified squamous epithelial tissue in the oral cavity?

Accepted Answer

Increased risk of infection and ulceration

Question 17

Which of the following equations would you use to calculate the percentage of neutrophils in a blood sample if there are 200 neutrophils out of 1000 total white blood cells?

Accepted Answer

$$\frac{200}{1000} 	imes 100 = 20\%$$

Question 18

Which of the following is NOT a characteristic of stratified squamous epithelial tissue?

Accepted Answer

Cells at the surface are cuboidal in shape

Question 19

A patient with a genetic disorder affecting keratin production would most likely have issues with which tissue type?

Accepted Answer

Stratified squamous epithelial tissue

Question 20

Which of the following best explains why blood is classified as a connective tissue?

Accepted Answer

It has cells suspended in an extracellular matrix (plasma) and connects body systems by transport.
