Which cells activate the immune system when foreign substances appear in the body?
T-cellls
What kind of cells activate the immune system when foreign substances appear?
Cells called antigen-presenting cells, such as dendritic cells and macrophages, play a key role in activating the immune system when foreign substances appear. These cells identify and capture foreign antigens, present them to T cells, and help initiate an immune response.
What kind of cells activate immune system and foreign substances appear?
Immune system activation primarily involves dendritic cells and macrophages, which are types of antigen-presenting cells (APCs). These cells capture and process foreign substances, such as pathogens, and present their antigens to T cells. This interaction activates T cells, which then help coordinate the immune response by signaling other immune cells, including B cells that produce antibodies. Together, these cells work to identify and eliminate foreign invaders.
How do macrophages in the skin contribute to the body's immune response against pathogens and foreign substances?
Macrophages in the skin play a key role in the body's immune response by engulfing and destroying pathogens and foreign substances. They also help to activate other immune cells and release signaling molecules to coordinate the overall immune response. This helps to protect the body from infections and maintain overall health.
What mounts the attack against particular foreign substances?
The immune system reacts to foreign substances.
What term describes foreign molcules that activate the immune system?
Antigen : NovaNet
Which system is to prevent foreign substances from entering the body to attack foreign substances that are in the body?
The Immune System is the defense network of the body. The immune system works with specific receptors on specialized cells - detecting foreign bodies and signaling for the immune system to destroy them.
What Protects the body against foreign substances?
Immune system
The immune system respond to agent cell or substances that are foreign or nonself collectively called?
antibodies
What system produces clls that inactivate foreign cells or substances in the body?
Immune System, bud.
What are substances such as viruses bacteria and fungi that can trigger an immune response?
Substances such as viruses, bacteria, and fungi that can trigger an immune response are known as pathogens. These microorganisms invade the body, leading to infections that activate the immune system to recognize and combat these foreign invaders. The immune response involves various cells and mechanisms, including antibodies and white blood cells, to eliminate the pathogens and protect the body. Additionally, the immune system can develop memory cells that help provide long-term immunity against future infections by the same pathogen.
What the immune system do?
It protects the body from foreign substances and pathogenic organisms by producing the immune response. <a href="http://www.tedthomas.com/">tax deeds for sale</a>
