Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells

1. Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells

The innate immune system builds a defense against dangerous pathogens and other foreign invaders of the body. Explore the innate immune system and discover the functions of various immune cells, like neutrophils, which are the first immune cells to respond to wounds.

Acquired Immunity: T Cells, B Cells and Antibodies

2. Acquired Immunity: T Cells, B Cells and Antibodies

People who have acquired immunity against an illness cannot be infected with it again. Discover how T cells, B cells, and antibodies work together to fight illnesses in this lesson.

Antibiotics and Vaccines

3. Antibiotics and Vaccines

Antibiotics and vaccines have a great contribution to the increase in life expectancy over time. Learn more about the history of antibiotics and vaccines, and how different types of vaccines are developed.

Flu Viruses, HIV and Immune System Evasion

4. Flu Viruses, HIV and Immune System Evasion

Some viruses, such as influenza and HIV, continue to spread and infect despite the human immune system. Understand characteristics of these viruses, such as rapid or high mutation rates, and how they help in evading the human body's protections.

Pathogens: Antibiotic Resistance and Virulence

5. Pathogens: Antibiotic Resistance and Virulence

Antibiotic resistance comes about when a disease causing microbe evolves to hold out against the effects of medications due to overuse. Study antibiotic resistance, its dangers, virulence, factors of virulence, and how virulence specificity is beneficial.
