Profe Claudio Nieto: The immune system

Profe Claudio Nieto explains a bit about the immune system.

It’s the body’s way of attacking invaders that harm the body.

Don’t overlook the ways you can improve your system.

Welcome to a fascinating journey through one of the most complex and vital systems of our body: the immune system.

We will delve into the depths of this intricate defense system, exploring from its basic functions to its extraordinary ability to fight external invaders, such as viruses and bacteria.

It’s surprising how much misunderstanding surrounds the immune system and, even more concerning, how many of us don’t properly care for it.

But why should we care about our immune system? Because ultimately, it determines our ability to face illnesses and stay healthy.

Our body is constantly exposed to a variety of threats, from bacteria to viruses.

However, our susceptibility to illness largely depends on the effectiveness of our immune system. What does this security and defense system represent?

It’s like a sophisticated surveillance system, where immune cells tirelessly work to identify and destroy any threats that arise, while recognizing and respecting healthy cells.

But how do we strengthen our immune system? The best strategy is prevention. Understanding how our defense system works allows us to take proactive measures to strengthen it.

From maintaining a healthy diet to exercising regularly, our daily habits can have a significant impact on our body’s ability to fight diseases.

One of the first obstacles invaders must overcome is the skin, our largest organ and a crucial barrier against infections.

In addition to the skin, we have other internal barriers, such as saliva, stomach hydrochloric acid, and elevated body temperature in the form of fever.

These defenses work together to create a hostile environment for invading microorganisms.

But what happens if an invader manages to overcome these barriers?

This is when the innate immune system comes into play, deploying specialized cells such as neutrophils and macrophages, which are responsible for detecting and destroying invaders.

Inflammation, though often feared, plays a crucial role in this process by increasing blood flow to the infected area and facilitating the arrival of additional immune cells.

But the immune response doesn’t end there. The adaptive immune system comes into play, triggering specific responses aimed at combating the invader more precisely and effectively.

T and B lymphocytes, two types of immune cells, collaborate to produce antibodies that identify and neutralize invaders.

While memory cells ensure a quick and efficient response in case of future encounters with the same pathogen.

This fascinating journey through our immune system reminds us of the importance of caring for and strengthening our health from the inside out.
