Very small infectious agents that live only by invading other cells are called viruses. Unlike bacteria, viruses cannot reproduce on their own and require a host cell to replicate and propagate. They consist of genetic material encased in a protein coat and can infect a wide range of organisms, including animals, plants, and bacteria.
What else can I help you with?
What are 3 main function of inflammation?
To get rid of the invading micro organism.
A substance produced by plasma cells of the immune system to fight infectious agents?
Antibodies, also known as immunoglobulins, are proteins produced by plasma cells in the immune system to target and neutralize infectious agents such as bacteria, viruses, and other pathogens. These antibodies bind to specific antigens on the surface of the pathogens, marking them for destruction by other immune cells.
What cells remove debris from the CNS?
Microglial cells are the primary cells responsible for removing debris from the CNS. These cells act as the resident immune cells of the CNS and are constantly surveying the brain for any abnormal or harmful substances. Upon detection, microglia engulf and remove the debris through a process called phagocytosis.
What cells are mainly used to kill infectious microbes and tumor cells?
The cells mainly used to kill infectious microbes and tumor cells are immune cells called cytotoxic T cells and natural killer cells. These cells can recognize infected or abnormal cells and destroy them by releasing toxic chemicals or by inducing programmed cell death.
What term means a white blood cell that surrounds and kills invading cells?
A macrophage is the type of white blood cell that surrounds and kills invading cells.
What are 3 main function of inflammation?
To get rid of the invading micro organism.
Why blood cells use to devour disease agents invading your body?
White blood cells.
What infectious agent live only by invading cells?
Viruses are infectious agents that can only replicate and survive by invading host cells and hijacking their cellular machinery. Once inside a host cell, viruses use the cell's resources to produce more viral particles, which can then go on to infect other cells. This process ultimately leads to the destruction of the host cell as new viruses are released to infect additional cells.
What are the slimy secretions in the lungs that protect it from dust and infectious agents?
The slimy secretions in the lungs that protect it from dust and infectious agents are called mucus. Mucus traps particles like dust and pathogens, preventing them from entering deeper into the lungs. The cilia in the respiratory tract then move the mucus upwards so it can be expelled from the body.

Antibodies, also known as immunoglobulins, are proteins produced by plasma cells in the immune system to target and neutralize infectious agents such as bacteria, viruses, and other pathogens. These antibodies bind to specific antigens on the surface of the pathogens, marking them for destruction by other immune cells.
What is a noncellular particle containing hereditary material called?
A Virus They have a protein coat to encase them
What is the gender of virus?
Viruses do not have a gender. They are microscopic infectious agents that replicate inside living cells.
What characteristics of the skin make it such a formidable barrier to infectious agents?
The skin's formidable barrier to infectious agents is primarily due to its structure and composition. It has a tough outer layer, the stratum corneum, made of dead keratinized cells that physically block pathogens. Additionally, the skin secretes antimicrobial peptides and oils that create a hostile environment for microorganisms. The presence of tightly packed cells and the acidic pH further enhance its protective function, making it difficult for infectious agents to penetrate and thrive.

A macrophage is the type of white blood cell that surrounds and kills invading cells.
What cell organism starts with the letter v?
A cell organism that starts with the letter "v" is a virus. Viruses are infectious agents that can only replicate inside the cells of other organisms.
