The signs of inflammation that came in the given statement. Introduction: An inflammation is the sequence of events in response to the infections that would limit the effects of injury or any agent in the body. It is the biological response against the harmful stimuli to eliminate the initial cause of the healthy tissue injury or damage. Its main function is to act as a defense mechanism of the body to remove the injurious agents from the body to prevent infections.

Expert Solution & Answer

Explanation of Solution

Given statement: While jogging in the surf, a person’s toes land on a jelly fish. The bottom of the toes becomes swollen, red, and warm to touch.

In the given case, the sting of the jellyfish causes inflammation that accompanies the visible signs such as redness, swelling, warmth, and pain. The inflammation begins through a signal provided by the damage caused by the sting. The basic steps involved in the inflammation are caused by the sting of jelly fish as follows:

Basic steps involved:

1. Release of various chemicals: Numerous chemicals such as histamine, interleukins, tumor necrosis factors (TNFs), chemotactic factors, leukotriene, and prostaglandins are released by the damaged cells of injured tissues basophils, mast cells, macrophages, dendritic cells, and infectious organisms to promote inflammation.
2. Vascular changes: The released chemical causes many local effects on the blood vessels such as:

Increased vascular permeability
Arteriolar vasodilation
Leukocyte adhesion

3. Leukocyte recruitment:The movement of the leukocyte through the blood at the site of infection occurs by the following processes:

a) Margination: The cell adhesion molecules (CAM) present on the surface of the leukocytes (first neutrophil and then macrophages) adhere to the endothelial capillaries present within the injured tissue.
b) Diapedesis: Here, the cells migrate to the site of infection by exiting the blood through “squeezing out” between the vessel walls.
c) Chemotaxis: Chemotaxis is the movement of cells along a chemical gradient formed due to the chemicals release by the damaged cells, dead cells, or invading pathogens. Cytokines and granulocyte-macrophage colony-stimulating factor (GM-CSF) are released to attract more macrophages to the site of infection. IL-1 released by macrophages induces fever in the body.
d) Delivery of plasma proteins: Several plasma proteins such as immunoglobulin’s complement, clotting proteins, and kinins are brought into the infection site that cause local effects such as increased vascular permeability, pain, heat, and swelling on the infected site.

4. Tissue repair and healing:Immune cells and their secretions process the pathogen and the newly formed lymph carries the pathogen with the unwanted dead cells and cell debris from the interstitial space of the tissue. The exudate (fluid and cellular/protein mix) is passed through the lymph nodes for monitoring, transported liver, and then, removed from the body.

The cardinal signs of inflammation are as follows:

1. Redness: Inflammation increases the vascular permeability which causes the flow of a large amount of blood toward the site of infection. Due to the increased blood flow, there will be redness at the site of infection.
2. Heat: The heat will be generated at the site of infection due to the increased blood flow as well as the increased metabolic activity of cells within the area.
3. Swelling: As a result of inflammation, a large amount of fluid is lost from capillaries into the interstitial space that causes swelling around the injured site.
4. Pain: Pain occurs when the pain receptors are stimulated due to the compression from the accumulation of interstitial fluid and by the irritation of the released microbial substances, kinins, or prostaglandins.
5. Loss of function: Loss of function occurs due to the pain and swelling.

Thus, several immune factors produced as a result of inflammation neutralize the toxin from the jellyfish.
