Which of the following is the effect of inflammation in the healing process?
Pulls the edges of the wound together
Causes bleeding to clean out the wound
Cleans out debris and toxins from the wound
Builds the scab to protect the wound
The Correct Answer is C
a. Pulls the edges of the wound together: Wound closure is a later stage of healing, not a primary function of inflammation.
b. Causes bleeding to clean out the wound: While some bleeding might occur initially, inflammation doesn't actively cause bleeding to clean the wound.
c. Cleans out debris and toxins from the wound: Inflammation is a natural response to injury or infection. It involves increased blood flow, redness, swelling, and heat. This process helps to deliver white blood cells and other immune factors to the area to fight infection and remove debris and damaged tissues, promoting healing.
d. Builds the scab to protect the wound: Scab formation is a result of dried blood and plasma, not a direct effect of inflammation.

b. Artificial active: Artificial active immunity is acquired through vaccination, where a person's immune system is exposed to a weakened or inactive form of a pathogen, such as the varicella (chickenpox) virus, to stimulate an immune response and the production of antibodies.
c: Natural active - Natural active immunity occurs when a person is exposed to a pathogen in the environment and develops an immune response, such as contracting and recovering from a disease like chickenpox.

b. Leukocytes: Leukocytes, also known as white blood cells, are involved in the immune response and protect the body from pathogens such as bacteria, viruses, and fungi.
c: Thrombocytes - Thrombocytes, or platelets, are involved in blood clotting but not in protecting the body from pathogens.
d: Erythrocytes - Erythrocytes, or red blood cells, are primarily involved in transporting oxygen and carbon dioxide and do not play a direct role in immune defense.
