Textbook Question

Chapter 34, Problem 2MCQ

Histamine acts on the _____, causing redness and swelling.

a. white blood cells

b. cells lining blood vessels

c. outermost layer of skin

d. red blood cells

Expert Solution & Answer

Summary Introduction

Introduction:

Inflammation is caused in the blood cells due to the entry of the pathogens. It causes redness and swelling in the blood vessels. It is released from the mast cells at the site of injury. It causes the blood vessels to dilate and increases the membrane permeability. The white blood cells reach the site of infection by squeezing through the spaces in the capillaries and blood vessels.

Answer to Problem 2MCQ

Correct answer:

Histamine acts on the cells lining blood vessels, causing redness and inflammation. Therefore, option b. is correct.

Explanation of Solution

Reason for the correct statement:

The injury to the blood vessels causes the release of the histamine from the mast cells. It is a chemical mediator of the damage of the cell membrane.

Option b. is given as “cells lining blood vessels”.

As, “Histamine acts on the cells lining blood vessels causing redness and swelling”, is the right answer.

Hence, option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “white blood cells”.

White blood cells reach the site of infection after an injury but histamine is released during redness and inflammation of the blood vessels. So, it is a wrong answer.

Option c. is given as “outermost layer of skin”.

The outermost layer of the skin is called as epidermis which gets destroyed during infection but histamine is released from the mast cells during redness and swelling. So, it is a wrong answer.

Option d. is given as “red blood cells”.

Red blood cells are present at the site of injury but histamine is released from the site of redness and swelling. So, it is a wrong answer.

Hence, options a., c., and d. are incorrect.

Conclusion

Inflammation causes redness and swelling at the site of infection due to the infection caused by the microorganisms leading to the release of histamine from the mast cells.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?
