Accepted Answer

Lymph nodes

Question 3

A patient has a swollen tonsil after a throat infection. Which best describes the tonsil's role in the lymphatic system?

Accepted Answer

It is a lymph nodule that traps pathogens entering through the mouth

Question 4

Which of the following is NOT a lymphatic organ?

Accepted Answer

Accepted Answer

Lymph nodes are encapsulated and filter lymph; nodules are unencapsulated and found in mucosal tissues

Question 6

Which of the following best describes the flow of lymph through the body?

Accepted Answer

Question 7

Which of the following is a correct definition of immunity?

Accepted Answer

The ability of the body to resist and defend against disease-causing agents

Question 8

Which of the following is a key difference between innate and adaptive immunity?

Accepted Answer

Innate immunity is present at birth and responds rapidly; adaptive immunity develops after exposure and is specific to pathogens

Question 9

A person receives a vaccine for influenza. Which best describes how the vaccine works?

Accepted Answer

Question 13

Which equation best represents the relationship between hydrostatic pressure and lymph flow?

Accepted Answer

$$Q = \frac{\Delta P}{R}$$

Question 14

During inflammation, which cardinal sign is caused by increased blood flow to the affected area?

Accepted Answer

Question 15

Which step occurs first in the inflammatory response?

Accepted Answer

Vasodilation and increased permeability of blood vessels

Question 16

Which of the following best describes the PLAN of attack by antibodies?

Accepted Answer

Question 17

Which immune cell type is most involved in cell-mediated immunity?

Accepted Answer

T cells

Question 18

Which of the following is a function of the spleen in the lymphatic system?

Accepted Answer

Question 19

Which of the following best describes the relationship between the immune and lymphatic systems?

Accepted Answer
