What else can I help you with?
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.
What cells are involved in specific defense?
Cells involved in specific defense include B and T lymphocytes. B cells produce antibodies that can recognize specific pathogens, while T cells can directly kill infected cells or coordinate immune responses. These cells are crucial for mounting a targeted and effective immune response against pathogens.
How does Mucus serves as a nonspecific defense to pathogens by?
Mucus serves as a nonspecific defense to pathogens by trapping them as they try to enter the body through the respiratory or digestive system. The mucus contains enzymes and antibodies that help neutralize and eliminate pathogens, preventing them from causing infections. Additionally, the cilia in the respiratory tract help move the mucus and trapped pathogens out of the body.
Function of the white blood cells?
White blood cells are the body's primary defense against infections. They detect and eliminate pathogens like bacteria, viruses, and other harmful substances. White blood cells also help in the body's immune response by producing antibodies and activating other immune cells.
What is the bodys first defense against bacteria and viruses?
Lysozymes
What pathogens respond to antibodies?
Pathogens such as bacteria, viruses, fungi, and parasites can respond to antibodies produced by the immune system. Antibodies work by binding to specific antigens on the surface of pathogens, marking them for destruction by other immune cells. This antibody response is a key component of the adaptive immune system's defense mechanism against infections.
What is bodies second line of defense against pathogens?
the body's second line of defense against pathogens is the B cells.
How do your help keep pathogens out of your body?
through antibodies and certain blood vessels ears are the #1 defense
What are the 5 lines of defense against pathogens?
4

How do your ears help keep pathogens out of your body?
through antibodies and certain blood vessels ears are the #1 defense
What of the human system is on defense against pathogens?
The immune system
What is a fact about the integumentary system?
It is the first line of defense against pathogens.
What cells are involved in specific defense?
Cells involved in specific defense include B and T lymphocytes. B cells produce antibodies that can recognize specific pathogens, while T cells can directly kill infected cells or coordinate immune responses. These cells are crucial for mounting a targeted and effective immune response against pathogens.
What organ is your first line of defense against pathogens?
The integumentary system (skin) and mucous membranes are the first line of defense. They provide a physical barrier against invasion of pathogens. Any break in this physical barrier, such as a cut, makes it easier for pathogens to enter your body.
What are two types of immune respones in the second line of defence?
The body has three main lines of defense against pathogens. They are as follows:First line of defense: Skin, Mucous membranes, and Secretions of skin and mucous membranesSecond line of defense: Phagocytic white blood cells, Antimicrobial proteins, and the Inflammatory responseThird line of defense: Lymphocytes, and Antibodies
True or false The skin provides the first defense against invasion by pathogens?
True. The skin acts as a physical barrier and provides the first line of defense against invasion by pathogens, preventing them from entering the body.
