TED-Ed: Your body vs. implants - Kaitlyn Sadtler
Why do medical implants like insulin pumps and prosthetic knees need replacement? Explore how the immune system fights implants and how new devices are trying to help. -- Insulin pumps improve the lives of millions of people with...
Crash Course
Immune System, part 1: Crash Course A&P
Our final episodes of Anatomy & Physiology explore the way your body keeps all that complex, intricate stuff alive and healthy -- your immune system. The immune system's responses begin with physical barriers like skin and mucous...
Professor Dave Explains
Basophils and Eosinophils
We are almost done looking at the cells of the innate immune system, but two of the most important are basophils and eosinophils. What do these cells do? What types of receptors do they express? Let's get a closer look!
Professor Dave Explains
Mast Cells: Strategic Granulocytes
We've covered macrophages, dendritic cells, and neutrophils, so let's move on the mast cells. These are examples of granulocytes, and they are involved in a variety of immune responses. Let's get a closer look now!
Professor Dave Explains
Neutrophils: First Line of Defense
We've covered macrophages and dendritic cells, so let's move on to neutrophils. These are the most abundant white blood cells, and they act as the first line of defense in innate immunity. How do they form, and what do they do...
Catalyst University
Catalytic Mechanism of Myeloperoxidase & Hypochlorous Acid Functions
Here we explore the catalytic mechanism of Myeloperoxidase and subsequent formation of Hypochlorous Acid and Hypothiocyanite, two reactive oxidative species (ROS). We will also see functions of Hypochlorous Acid.
Catalyst University
Physiology of Neutrophils, Macrophages, and Dendritic Cells
In this video, we explore the functions of neutrophils, macrophages, and dendritic cells.

Macrocytic Anemia | Megaloblastic vs Non-Megaloblastic | Approach & Causes
Macrocytic Anemia | Megaloblastic vs Non-Megaloblastic | Approach & Causes Macrocytic anemia is a condition with low hemoglobin and high MCV (mean corpuscular volume). Macrocytic anemia can be broken down into Megaloblastic and...
Professor Dave Explains
The Inflammatory Response
We touched upon the inflammatory response in the Anatomy & Physiology series, but now it's time to go much deeper. What is inflammation on the cellular level? Which cell types are involved with the response, and what are the mechanisms...

Immune System: Innate and Adaptive Immunity Explained
The immune system (or immunity) can be divided into two types - innate and adaptive immunity. This video has an immune system animation. The innate immune system consists of defenses against infection that are activated instantly as a...

The Cells of Innate Immunity (and Mechanism)
The Innate immune response is a general response your immune system has against foreign invaders. And there are special cells involved in the process. In this video, we'll cover those cells and the roles they play.

White Blood Cells Introduction (aka Leukocytes) | How they Work
White blood cells, a.k.a. Leukocytes. These are the second most common cell type in the blood. But what do we know about their structure and what exactly do they do? Well, that’s what we cover in this video.

The Immune System
The main role of the immune system is to prevent disease caused by infection. Infections can be caused by a wide variety of pathogens, including bacteria, fungi, parasites (such as malaria) and viruses (such as influenza and the common...
Science Friday Initiative
Science Friday: March of the Immune Cells
Paul Kubes filmed the immune cells, neutrophils finding their way to a mouse's wounded liver. The researchers wanted to understand how neutrophils find injuries when bacteria aren't around to signal the damage. [3:32]
Crash Course
Crash Course A&p #45: Immune System, Part 1
Find out how the immune system's responses begin with physical barriers like skin and mucous membranes, and when they're not enough, there are phagocytes, the neutrophils, and macrophages. It also features the natural killer cells and...
