Salmonella bacteria can bypass the body's first line of defense, which includes physical barriers like skin and mucous membranes, by entering the body through contaminated food or water. Once ingested, they can survive the acidic environment of the stomach and adhere to the intestinal lining, allowing them to invade epithelial cells. By exploiting host cell mechanisms, Salmonella can also evade the immune response, facilitating their survival and proliferation within the host.
If bacteria get into the stomach of a human the first line of defense of the immune system that will potentially stop the bacteria is the gastric juice in the stomach.
Your skin,sweat,mucus,and tears is the first line of defense of your immune system. it is the original protector from bacteria and viruses
saliva, mucus, hairs and Skin
Lysozymes
skin and mucous membranes
skin and mucous membranes first line of defense second line-leukocytes and macrophages, inflammation and fever third is immune system
what first line of defence wiil stop bacteria
The main line of defense in the human body is the immune system, which helps to protect against pathogens such as bacteria, viruses, and parasites. This includes physical barriers like the skin, as well as specialized cells and proteins that work together to identify and neutralize harmful invaders.
The first line of defense includes the skin, breathing passage, mouth and stomach.
In the immune system, the first line of defense are mechanical and physical barriers, such as the skin and the cornea of the eye. The main line of defense, meanwhile, are the innate immunity and acquired immunity of an organism.
Well eat tutty. It ges through them as it does in the with second line fo defence okay. My name is AOL
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.
