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.

Immune cells can detect intracellular pathogens through pattern recognition receptors (PRRs) that recognize specific pathogen-associated molecular patterns (PAMPs). When PRRs on immune cells bind to PAMPs, it triggers a signaling cascade that activates the immune response against the intracellular pathogen. This process helps immune cells detect and respond to the presence of intracellular pathogens.

What do you mean by phagocytic in nature?
"Phagocytic" describes the function of certain immune cells that engulf and digest foreign particles, such as bacteria and debris, to help protect the body from infection and maintain tissue health. These cells, like macrophages and neutrophils, play a vital role in the immune response.
Not a principle of cell theory?
Cells must have a specific shape and size is not a principle of cell theory. Cell theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells come from pre-existing cells.
Do bacteria have smooth er?
No, bacteria do not have smooth endoplasmic reticulum (ER). Smooth ER is a cell organelle found in eukaryotic cells, not in prokaryotic cells like bacteria.
What is the direction of water movement in a cylinder of potato tissue in distilled water?
In a cylinder of potato tissue placed in distilled water, the direction of water movement will be from the external solution (distilled water) into the potato tissue due to osmosis. This is because the potato cells have a higher solute concentration compared to the external solution, resulting in water moving into the cells to equalize the concentration gradient.
Do bacteria have ER?
No, bacteria do not have endoplasmic reticulum (ER) like eukaryotic cells. Bacteria lack membrane-bound organelles, including the ER, and instead have a simpler internal structure.
What happens when the body cannot differentiate between pathogens and body cells?
The immune system will target the body's own cells
Is intracellular space same as intercellular space?
intracellular pathogens can only replicate inside a host cell, whereas extracellular pathogens can replicate independent of the host
How do cells involved in the innate immune response detect the presence of pathogens?
Leukocytes recognize unique molecules on pathogens
What is a network of cells tissues organs and chemicals that fight pathogens?
The immune system is a network of cells tissues organs and chemicals that fight pathogens. This is how the body keeps healthy and defends against invading illnesses.
What disease causes the body to attack pathogens and its normal cells?
Auto-immune
Which are special molecules of protein produced by the immune system that match parts of pathogens and prevent them from infecting cells?
Antibodies are special molecules of protein produced by the immune system that match parts of pathogens and prevent them from infecting cells.
Which cells in the immune system identify pathogens and distinguish one pathogen form another?
T cells
Which cells in the immune system identify pathogens and distinguish one pathogen from another?
B cells and Helper T cells
What is a network of cells tissues organs and chemicals that fights off pathogens?
immune system
What helps the immune system?
The system that helps the immune system is the circulatory system because it carries the white blood cells to where the pathogens are.
How does the immune system function and protect against pathogens?
The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens such as bacteria, viruses, fungi, and parasites. Its primary function is to recognize and eliminate these pathogens while distinguishing them from the body's own healthy cells. The immune system can be broadly divided into two main components: the innate immune system and the adaptive immune system. Innate immune system: This is the first line of defense and provides a rapid, nonspecific response to pathogens. It includes physical barriers like the skin and mucous membranes, as well as various cellular and chemical components. The innate immune system recognizes certain patterns associated with pathogens, called pathogen-associated molecular patterns (PAMPs), through receptors on immune cells. These cells include phagocytes (such as macrophages and neutrophils) that engulf and destroy pathogens, natural killer cells that kill infected cells, and dendritic cells that present antigens to initiate an adaptive immune response. The innate immune system also releases chemical signals called cytokines that help coordinate the immune response. Adaptive immune system: This is a specific and highly specialized defense mechanism that develops more slowly but provides long-term protection against specific pathogens. The adaptive immune system has the remarkable ability to recognize and remember specific pathogens it has encountered before. It involves two main types of cells: B cells and T cells. B cells: B cells produce antibodies, which are proteins that bind to specific molecules on pathogens called antigens. When an antigen is encountered, B cells undergo activation and differentiation into plasma cells that produce large quantities of antibodies. Antibodies can neutralize pathogens directly, mark them for destruction by other immune cells, or activate the complement system, which is a group of proteins that help eliminate pathogens. T cells: T cells have several roles in the immune response. Helper T cells recognize antigens presented by dendritic cells and help coordinate the immune response by releasing cytokines. Cytotoxic T cells, also known as killer T cells, directly destroy infected cells by releasing toxic substances. Regulatory T cells modulate the immune response to prevent excessive reactions and maintain tolerance to self-antigens. Both the innate and adaptive immune systems work together in a coordinated manner. When a pathogen breaches the physical barriers of the body, innate immune cells detect its presence and initiate a response. This response activates the adaptive immune system, which mounts a targeted attack against the specific pathogen. After the infection is cleared, some adaptive immune cells remain as memory cells, providing long-lasting immunity. If the same pathogen is encountered again, the immune system can mount a quicker and more effective response, preventing reinfection. It's important to note that the immune system is a highly intricate and dynamic system, and its functioning can be influenced by various factors such as genetics, overall health, nutrition, and previous exposure to pathogens.
What is the function of the immune system?
The function of the immune system is to protect your body from infection by pathogens and foreign invaders, or what the body perceives as invading "germs". Your immune system works to identify pathogens and sometimes other unrecognized cells, like tumor cells, that could cause disease and then to eliminate them from your system. Your body's immune system has an incredibly difficult task in this because some of these pathogens can be "sneaky": they can redesign (mutate) themselves to trick the immune system into misidentifying them as harmless cells rather than appropriately treating them as foreign invaders.
