Question

question 17 (1 point)
the swelling associated with inflammation decreases when the fluid
○ is lost in perspiration
○ is excreted in urine
○ returns to the blood
○ goes into lymph capillaries
question 18 (1 point)
the presence of which of the following indicates a current infection rather than a previous infection or vaccination?
○ ige
○ igm
○ igd
○ igg
○ iga

Explanation:

Question 17

In inflammation, the excess fluid (exudate) from the interstitial space can enter lymph capillaries (lymphatic system) to be drained, reducing swelling. Perspiration and urine excretion don't primarily reduce inflammatory swelling, and returning to blood isn't the main pathway for reducing inflammatory fluid buildup.

IgM is the first antibody produced during a current infection. IgG is associated with past infections/vaccination (long - lasting immunity), IgE with allergies/parasitic infections, IgD has less - defined roles in immunity, and IgA is for mucosal immunity. So IgM indicates a current infection.

Answer:

D. goes into lymph capillaries
