Immune System & Immune Response

1. Immune System & Immune Response

Your immune system protects you from foreign invaders that might harm you. When your immune system responds to these threats, it's called an immune response. Learn about two arms of immunity known as antibody-mediated and cell-mediated immunity.

Basic Principles of Infection Control

2. Basic Principles of Infection Control

We are going to gain an understanding of microorganisms and what it means to be pathogenic. This lesson will go on to discuss the importance of infection control.

Blood Coagulation and Wound Healing

3. Blood Coagulation and Wound Healing

When your blood vessels suffer damage, your body follows a sequence of events to promote blood clotting. In this lesson, you will learn about coagulation cascade and important clotting factors involved in wound healing.

The Three Phases of Wound Healing

4. The Three Phases of Wound Healing

In this lesson, you're going to learn the fundamental facts about the three phases of wound healing. These phases include inflammation, proliferation, and maturation. When you are through, take the quiz to see what you have learned.

Chronic Inflammation: Long Term Consequences

6. Chronic Inflammation: Long Term Consequences

This lesson explores the harmful effects of long-term inflammation. We'll define chronic inflammation, inflammatory mediators, and reactive oxygen species before covering some specific causes of chronic inflammation and its consequences.

The Inflammatory Response's Effect on the Entire Body

7. The Inflammatory Response's Effect on the Entire Body

This lesson will discuss two important roles systemic inflammation is involved in: fever and leukocytosis. It will also discuss the flip-side, two bad components of systemic inflammation: cachexia and anaphylactic shock.

Progress of Disease: Infection to Recovery

8. Progress of Disease: Infection to Recovery

This lesson will teach you about the five basic steps of the development of disease, what they are called, and what occurs during each phase. We'll talk about the incubation and prodromal period as well as the periods of convalescence, decline, and illness.
