The innate immune system is the body's first line of defense against infection and is present from birth. It includes physical barriers like the skin and mucous membranes, as well as cells and molecules that help destroy pathogens.

• 00:00:00 The video discusses the characteristics of innate immunity, which refers to the body's natural defense mechanisms. Humans and other animals are surrounded by a great number of strange substances and other living beings are so small we can't see them directly. We call these microorganisms "microorganisms." Some microorganisms and strange substances can harm us, so our body has mechanisms to prevent the entry of invaders and to recognize and defend against them if they manage to enter our body. We will explain the characteristics of our defenses and identify some daily habits that strengthen our immune system to fight against diseases from the moment of birth. Our living organisms possess physical and chemical barriers as well as cells and molecules that protect us from infections. All of this constitutes innate immunity. The skin is a physical barrier that prevents the entry of microorganisms on the surface of the skin. These substances are released and burn in the acidity, and the skin's oils and fats reduce the growth of microorganisms, which could be pathogenic. It is important to maintain the integrity of the skin, its cleaning and lubrication. Additionally, the digestive tract, respiratory system, and genitourinary system are covered by mucous membranes, which acts as a physical barrier that prevents the entry of microorganisms, pathogenic or not
• 00:05:00 The innate immune system is a rapid response system that helps repair cells and tissues, reduces stress, and is present from birth. Some common features of innate immunity include barriers like the skin and mucous membranes, which are always present and prevent pathogen entry immediately. In addition, tears, sweat, and saliva contain antimicrobial proteins. When the skin or mucous membranes are damaged, neutrophils and some soluble molecules like proteins in the complement system destroy pathogens. The innate immune system has the following characteristics: it acts quickly, in minutes or hours, is born with it, and does not need prior contact with the pathogen. It includes some physical barriers and recognizes pathogens with low accuracy.
