immunity and producing antigens that protect the body...
Prevents the invasion of of pathogen into the body and acts as the first and second line of defence Agianst pathogens
what first line of defence wiil stop bacteria
The difference between the first and second line of defence is that the first line of defence is your physical barrier like your skin and it protects you from most pathogens entering your body and the sweat and oil on your skin prevent some pathogens from growing on your body. the second line of defence is when a pathogen makes it past the first line of defence your body can mount an immune response to the attack and destroy the invader. Whether or not the response succeeds depends very much on your body's ability to distinguish between cells that belong to it and cells that do not.
The second line of defence is the non specific, it includes antimicrobial proteins, phagocytes and other cells. - In this state to inhibit spread of invader through out the body. -Inflamation, is its hallmark and most important mechanism.
The body's first line of defense consists of physical and chemical barriers that prevent pathogens from entering, such as the skin, mucous membranes, and secretions like saliva and stomach acid. The second line of defense involves the innate immune response, which includes white blood cells, inflammation, and the activation of proteins that help fight infections. Together, these defenses provide a robust response to protect the body from harmful invaders.
The skin is the first line of defence( protection) that is why lesion in the skin leads to infection.
With the 1st, 2nd and 3rd line of defence
This may or may not be what you had in mind, but the first line of defense is the skin, which keeps out pathogenic organisms. Then there is the immune system.
The body's first line of defense against HIV is the mucous membranes. These membranes act as a physical barrier that helps prevent the virus from entering the body through openings like the mouth, nose, and genitals. Additionally, the mucous membranes also produce substances like mucus and enzymes that can help trap and eliminate pathogens like HIV.
Yes, memory cells are part of the adaptive immune response, which is considered the third line of defense in the immune system. Memory cells are responsible for remembering previous encounters with specific pathogens and mounting a quicker and more efficient immune response upon re-exposure.
The first line of defense against infection or contamination of I.V. products is by hand washing.
