This course on Parasitology and Immunology explores the body's defense mechanisms against infections. It covers different types of immunity, defense mechanisms, processes, functions, and the interaction of antibodies with antigens. The course delves into hypersensitivity, autoimmunity, and the immunology of tissue transplantation. Students will gain an understanding of infections, protection, and the roles of various cells and molecules in the immune response. The course aims to provide a comprehensive overview of parasitology and immunology.

What you'll read
The real module and unit structure of BIO406, taken from the course material NOUN publishes.
One paragraph, so you can see how it reads
BIO406 · UNIT 2: INFECTION, IMMUNITY AND PROTECTION
Naturally acquired active immunity occurs when a person is exposed to a live pathogen, and develops a primary immune response, which leads to immunological memory. This type of immunity is “natural” because it is not induced by deliberate exposure. Many disorders of immune system function such as immunodeficiency and immuno-suppression can affect the formation of active immunity.
What you should be able to do
- Define and differentiate between various types of immunity.
- Explain the mechanisms of infection and the body's defense strategies.
- Describe the nature of antigens and their interaction with antibodies.
- Classify and explain the different types of hypersensitivity reactions.
- Discuss the causes and pathogenesis of autoimmunity.
- Explain the immunology of tissue transplantation and graft rejection.

Where it gets hard
The units students slow down on, and what makes each one heavy.
- Module 1: Immunity
Unit 3: Antigen
Understanding the complex interactions between antigens and antibodies requires a strong foundation in biochemistry and molecular biology.
- Module 2: Hypersensitivity
Unit 1: Hypersensitivity
Differentiating between the various types of hypersensitivity reactions (I-IV) and their underlying mechanisms requires careful attention to detail.
