Skin, mucous membranes, sloughing of dead skin, tears, sweat, normal microbial flora of skin.
Non specific defenses against pathogens include intact skin, temperature, neutophils, macrophages, and natural kills cells.
The body's natural defenses against pathogens also include mucus, which traps pathogens and debris in the respiratory and digestive tracts. Additionally, the immune system plays a crucial role, using white blood cells to identify and destroy invaders. Other defenses include stomach acid, which kills harmful microorganisms, and the presence of beneficial bacteria that outcompete pathogens. Together, these mechanisms help protect the body from infections.
Your skin is the first line of defense.
Our bodies have many natural defences. Our main internal defence would be our immune system which helps combat bacterial and viral diseases. Our main external defence would be our skin which protects our body and prevents pathogens and microbes from entering our bodies. Hope This Helps :D
The body's internal defenses include the immune system, which comprises various cells and proteins that work together to identify and eliminate pathogens like bacteria and viruses. Key components include white blood cells, antibodies, and the complement system, which help detect and destroy invaders. Additionally, the body has mechanisms such as inflammation and fever that enhance the immune response. Together, these defenses maintain health and protect against infections.
Pathogens
The body's second line of defense, which includes inflammatory responses and phagocytic cells, comes into play when pathogens manage to breach the first line of defense (skin and mucous membranes). These responses help contain and eliminate the pathogens before they can cause harm.
They can fight them using white blood cells to create anti bodys.
Lysozymes
The tonsils are apart of the lymphatic system. They aid in the bodys ability to fight germs.
White
True. Natural killer cells play a crucial role in immune surveillance by recognizing and eliminating cancerous cells, making them one of the body's important defenses against cancer. They can directly kill cancer cells and also produce cytokines to enhance the immune response against cancer.
