The body has three lines of defense against pathogens: the first line is physical barriers like skin and mucous membranes, the second line is non-specific immune responses like inflammation and phagocytosis by white blood cells, and the third line is the adaptive immune response involving specialized cells and proteins to target specific pathogens.

What is the difference between innate and adaptive defenses?
Innate defenses are the body's first line of defense against pathogens and are non-specific, meaning they target any foreign invader. Adaptive defenses are more specific and target particular pathogens, developing over time as the body is exposed to different threats. Innate defenses are always present and ready to act, while adaptive defenses take time to develop but provide long-lasting immunity.
How do cancer cells work to proliferate and evade the body's natural defenses?
Cancer cells proliferate by growing and dividing uncontrollably, forming tumors. They evade the body's natural defenses by mutating to avoid detection by the immune system and by disrupting normal cell signaling pathways that regulate cell growth and death.
The body's main defense against pathogens is the?
immune system, which includes cells like white blood cells and antibodies that can recognize and neutralize harmful pathogens like bacteria, viruses, and fungi. These immune responses can help prevent infections and keep the body healthy.
How long before a red line under the skin appears from an infection?
A red line under the skin can appear within a few hours to a few days after an infection, depending on the severity and type of infection. It is essential to seek medical attention promptly if you notice a red line under your skin, as it can be a sign of a serious infection spreading.
Are non- specific body defenses are innate while specific are adaptive?
Innate is a broad general response against any pathogen. It is very quick response but it is limited in how well it can defend your body. It is absolutely necessary to have a functioning innate immunity or your adaptive immunity will not be able to respond efficiently. Adaptive has a very specific response against a pathogen. On first exposure it may time several weeks to acquire the appropriate defenses, however, on secondary exposure it is a very quick response. It has long term memory so you are protected for a long time against that same pathogen.
What are the six first line defenses of the body?
The first six lines defenses of the body are mucous membrane, skin, chemicals, pH, hair, and cilia.
What are your body's first-line defenses against pathogens in general?
Your skin is the first line of defense.
What is your third line of defense?
Your body's third line of defense is specific defenses, such as the immune response.
What are your body' first-line defenses against pathogens in general?
Your skin is the first line of 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.
If foreign substances pass the body's first line of defenses and into the bloodstream what happens?
They are attacked by lymphocytes .
Why it is important that your body has several different defenses to protect you from pathogens?
Your body is really a possible large dinner table for pathogens that are found everywhere. You need as many defenses as you have to fend them off.
Why are physical defenses called the body's first line of defence against disease?
Physical defenses are considered the body's first line of defense against disease because they provide immediate protection against pathogens. These barriers, such as the skin, mucous membranes, and cilia, prevent the entry of harmful microorganisms into the body. They act as a physical shield, blocking pathogens and reducing the likelihood of infection. Additionally, these defenses are always present and ready to respond, making them crucial for maintaining overall health.
What is the difference between innate and adaptive defenses?
Innate defenses are the body's first line of defense against pathogens and are non-specific, meaning they target any foreign invader. Adaptive defenses are more specific and target particular pathogens, developing over time as the body is exposed to different threats. Innate defenses are always present and ready to act, while adaptive defenses take time to develop but provide long-lasting immunity.
