lymph
Non specific defenses against pathogens include intact skin, temperature, neutophils, macrophages, and natural kills cells.
The body's main defense barrier against microorganisms is the immune system. This system includes physical barriers like the skin and mucous membranes, as well as specialized cells and proteins that identify and destroy pathogens to prevent infections. Additionally, the body has inflammatory responses that help to contain and eliminate invading microorganisms.
Your skin is the first line of defense.
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.
The tonsils are apart of the lymphatic system. They aid in the bodys ability to fight germs.
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.
Inflammation is one of the bodies non-specific defenses. It helps localize the infection to stop it from spreading to other areas of the body so that your bodys other defenses can come in and fight the infection.
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.
White blood cells
Neutrophils
White blood cells, also known as leukocytes, are the cells that play a crucial role in the body's defense against invading microbes. They work by identifying and attacking foreign invaders such as bacteria, viruses, and other pathogens to help prevent infections.
