What system is the body's first line of defense?
The body's first line of defense is the innate immune system, which includes physical and chemical barriers like skin, mucous membranes, and stomach acid that help prevent pathogens from entering the body. If pathogens breach these barriers, the immune system responds with inflammation and activates other immune cells to fight off the infection.
How does the body's first line of defense function?
The Body's first line defense acts as physical barriers, in which it functions by trapping the pathogens and blocking them from entering the body. Also, all first line defenses act the same way to all pathogens, in which they're called non-specific defense.
What is the first line of Mitch's non-specific defenses?
The first line of Mitch's non-specific defenses is the physical barriers provided by the skin and mucous membranes. These barriers serve as the body's first line of defense against pathogens by preventing their entry into the body.
What provides mechanical barriers?
There are multiple chemical barriers present in the body. The sebum of the skin, the lactimal secretions of the eye, the gastric acid of the stomach and the urinary acids of the urinary bladder are all examples of chemical barriers to infection.
What are your bodys first line defenses against pathogens in general?
Your skin is the first line of defense.

What is produced by epithelial membranes as a first line of defense protection?
Mucous secretions are produced by epithelial membranes as a first line of defense protection. The mucous helps to trap pathogens and foreign particles, preventing them from entering the body and causing infections. Additionally, epithelial membranes also produce antimicrobial peptides that can help to kill or inhibit the growth of pathogens.

What organ is your first line of defense against pathogens?
The integumentary system (skin) and mucous membranes are the first line of defense. They provide a physical barrier against invasion of pathogens. Any break in this physical barrier, such as a cut, makes it easier for pathogens to enter your body.
Which one of the following participate in the bodys second line of defence?
Macrophages, natural killer cells, and complement proteins participate in the body's second line of defense. These components help to identify and eliminate pathogens that have breached the first line of defense, which includes physical and chemical barriers like the skin and mucous membranes.
What are your bodys first line defenses against pathogens in general?
Your skin is the first line of defense.
What are the first 3 lines of defense?
The first line of defense is physical barriers like skin and mucous membranes, which prevent pathogens from entering the body. The second line of defense includes immune cells like neutrophils and macrophages, which attack pathogens that breach the first line. The third line of defense is the adaptive immune response, involving T and B cells that target specific pathogens and create immunological memory.
The skin and mucous membranes are examples of?
The skin and mucous membranes are examples of physical barriers that serve as the first line of defense for the immune system. They help to prevent pathogens from entering the body and causing infection.
Which action is an example of a chemical defense in your skin?
One example of a chemical defense in your skin is the secretion of antimicrobial peptides like defensins. These peptides help to kill bacteria and other pathogens on your skin's surface, providing a first line of defense against infections.
What are different ways the body can use for defense?
The body can use physical barriers like skin and mucus membranes, the immune system to detect and eliminate pathogens, inflammation to recruit immune cells to the site of infection, and fever to create an inhospitable environment for pathogens.
