What else can I help you with?
How can pathogens cause disease in the human body?
Pathogens can cause disease in the human body by invading tissues, releasing toxins, and triggering an immune response that can damage healthy cells and tissues.
Group of microorganisms composed only of hereditary material wrapped in a protein covering?
This description fits the definition of a virus. Viruses are not considered living organisms because they lack the ability to carry out metabolic processes on their own and reproduce by invading host cells.
What is found in the lymph nodes and tonsils?
Lymph nodes are located along lymphatic pathways, and contain lymphocytes and macrophages, which destroy invading microorganisms. They remove and destroy potentially harmful foreign particles from the lymph through phagocytosis by macrophages. They are also the centers for the production of lymphocytes that act against foreign particles.Lymph nodes are located along lymphatic pathways, and contain lymphocytes and macrophages, which destroy invading microorganisms.
What Are present in the cell which are responsible for digestion of microbes?
Lysosomes are responsible for digesting microbes in the cell. They contain enzymes that can break down various molecules, including those from invading microorganisms. Through a process called phagocytosis, lysosomes can engulf and degrade foreign particles or pathogens within the cell.
What human cell uses phagocytosis as a mechanism of defense?
White blood cells, particularly macrophages and neutrophils, use phagocytosis as a mechanism of defense against invading pathogens. These cells engulf and digest foreign particles such as bacteria, viruses, and cellular debris to protect the body from infections.
Any substance released by invading pathogens?
antigen
If the white blood cells are not able to stop invading pathogens?
the skin keeps out most pathogens
What are some of your body's defenses against invading microorganisms?
lymph
What is the invading material in the body which triggers the body to produce an antibody?
Pathogens
Where in the body do acids protect us from invading pathogens?
Immune system,
What can happen if the white blood cells are not able to stop invading pathogens?
AIDs.
What do you call a white blood cell that attacks invading pathogens?
killer cells
How do white blood cells get to the infection?
White blood cells can get to the site of infection through a process called chemotaxis, where they are attracted to the area by chemical signals released by the damaged tissues or invading pathogens. Once they reach the infection site, white blood cells can engulf and destroy the invading microorganisms to help fight the infection.
The body's nonspecific defenses against invading pathogens include?
Mucus, sweat, and tears
What is the white blood cell that attacks the invading pathogens?
The white blood cell that attacks invading pathogens is called a neutrophil. Neutrophils are a type of phagocyte, which means they engulf and destroy pathogens through a process called phagocytosis. They are an important part of the body's immune response to infections.
What is the bodys main defence barrier against microorgansism?
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.
If white blood cells are not able to stop invading pathogens what happens next?
the disease invades them and our body
