Summary of The Immune System

00:00:00 - 00:10:00

The immune system is a complex system that helps to protect us from infection by attacking viruses and other harmful cells. It involves the production of antibodies and killer T cells, as well as the help of humors in the body.

• 00:00:00 The immune system protects us from infection by attacking any invaders that are not part of our body. This includes pathogens such as viruses and bacteria, as well as foreign objects such as heart implants. The immune system also has a specific immune response that attacks specific invaders.
• 00:05:00 The immune system protects us from infection by viruses and other harmful cells. B lymphocytes produce antibodies specific to particular antigens, and T lymphocytes kill infected cells.
• 00:10:00 The immune system defends the body from infections by attacking and killing viruses and other cells. The humors of the body, which are liquid substances, help to fight the infections. The immune system also involves the production of antibodies and immune cells (killer T cells and B cells) that can attack and kill the virus or cells that are infected. Colds are caused by the viruses that cause them and can be fought by the immune system by producing antibodies and immune cells quickly.
