Specialized globular proteins that attack foreign proteins and pathogens is known as what?
They are known as killer T cells, which are a type of white blood cell that engulfs and digests foreign proteins/pathogens that enter the body. They work in conjunction with another type of white blood cell called Helper T cells which do the actual targeting of the pathogen/protein.

How do complement proteins cause foreign cell lysis?
Complement proteins cause foreign cell lysis through a process known as the complement cascade, which is initiated when these proteins are activated in response to pathogens. Once activated, they form a membrane attack complex (MAC) that inserts itself into the foreign cell's membrane, creating pores. These pores disrupt the osmotic balance of the cell, leading to an influx of water and ultimately resulting in cell swelling and lysis. This mechanism helps eliminate pathogens from the body effectively.
Which part of the lung cells produce protein in mucus?
Goblet cells in the respiratory tract produce and secrete proteins called mucins, which contribute to mucus production. These proteins help to trap and remove foreign particles and pathogens from the airways.
What are phagocytes made of?
Phagocytes are a type of white blood cell that are made up of various components including a cell membrane, cytoplasm, and a nucleus. They also contain specialized structures like lysosomes that help them to engulf and digest foreign particles or pathogens in the body.
Large proteins of the blood and body fluids produced by the immune system in response to the invasion of the body by foreign molecules?
Antibodies are large proteins produced by the immune system that specifically recognize and bind to foreign molecules called antigens. They help the immune system to identify and neutralize pathogens such as bacteria, viruses, and other harmful substances. Each antibody is unique and can target a specific antigen.
Where would you find the kupffer cells of the liver?
Kupffer cells are specialized macrophages found in the liver, specifically within the sinusoids, which are specialized blood vessels in the liver. They play a key role in the immune system by removing debris, pathogens, and other foreign particles from the blood passing through the liver.

What are plasma proteins that non specifically bind to pathogens?
Nonspecific plasma proteins that bind to pathogens are:Non-phagocytic leucocytes - Basophil. which contains granules of toxic chemicals that can digest foreign microorganisms. They are involved in allergic response.Mast Cells - They are similar to basophils, and contain inflammatory chemicals including histamine and seratonin that cause blood vessels near a wound to constrict.Complement proteins are plasma proteins which have a role in nonspecific and specific defenses.

What is a group of proteins that normally circulate in the blood in an inactive form and activated by contact with nonspecific antigens such as foreign blood cells or bacteria is known as?
A group of proteins that circulates in the blood in an inactive form and is activated by contact with nonspecific antigens, such as foreign blood cells or bacteria, is known as the complement system. This system plays a crucial role in the immune response by helping to clear pathogens and promote inflammation. Once activated, complement proteins can enhance opsonization, facilitate phagocytosis, and contribute to the lysis of pathogens.
Which part of the lung cells produce protein in mucus?
Goblet cells in the respiratory tract produce and secrete proteins called mucins, which contribute to mucus production. These proteins help to trap and remove foreign particles and pathogens from the airways.
How do the immune cells discover intracellular pathogens?
All cells have specialized proteins on their surface that show a sampling of the contents of the cell to certain immune cells, which recognize these samples as self or foreign (i.e. intracellular pathogens) and kill infected cells.
What is the root word for antibody?
The root word for "antibody" is "body." The prefix "anti-" means "against," indicating that antibodies are proteins produced by the immune system to combat foreign substances, such as pathogens. Thus, "antibody" refers to a substance that acts against the body’s foreign invaders.
What are phagocytes made of?
Phagocytes are a type of white blood cell that are made up of various components including a cell membrane, cytoplasm, and a nucleus. They also contain specialized structures like lysosomes that help them to engulf and digest foreign particles or pathogens in the body.
What is present in the blood to protect the body from infectons and disease?
The blood contains several components that protect the body from infections and diseases, primarily white blood cells (leukocytes), antibodies, and complement proteins. White blood cells, such as lymphocytes and phagocytes, identify and destroy pathogens. Antibodies are specific proteins produced by B cells that recognize and neutralize foreign invaders. Additionally, complement proteins enhance the ability of antibodies and phagocytes to clear pathogens from the body.
The group of proteins that normally circulate in the blood in an inactive form and are activated by contact with nonspecific antigens such as foreign blood cells or bacteria?
These proteins are part of the complement system, which forms a crucial part of the immune response. Once activated, the complement proteins can lead to the destruction of pathogens through processes such as opsonization, inflammation, and cell lysis.
What do phagocytes do for a site of injury?
Engulf pathogens, backteria, foreign bodies
