What is immune function and immunity?

Children have poor resistance, and the first thing to do is to advocate a normal work and rest time. Secondly, a balanced diet is required.

In addition, don't clean the environment too much, so that there is no suitable environment to cultivate children's resistance.

Of course, it is necessary to avoid going to places that are too densely populated and lively, as there are a large number of pathogenic bacteria, which can easily cause children to get sick. Finally, certain medications can partially improve resistance, but they are not the first choice.

Now there are more and more children with poor immunity, which breaks the hearts of parents who run to the hospital with their children every once in a while. How can a little sweat and a little wind blow a little bit and the child will catch a cold? Obviously, this is the reason for the child's poor immunity.

Resistance and immunity are words that we hear more frequently in our lives, but what is the difference between the two?

In simple terms,Resistance is a kind of resistance, while immunity is a kind of body's ability to recognize and distinguish diseases.

1. Resistance.

Resistance refers to the fact that the various systems of the human body work closely together through the control of the central system so that the body can function properly. Among the major systems, the immune system is the most important system that affects a person's resistance, the immune system and resists the invasion of external pathogens, so as to help the human body avoid the occurrence of various diseases to the greatest extent, and the defense ability generated by this work is called resistance.

2. Immunity.

For the human body, immunity is a defense mechanism, which can identify and eliminate foreign bodies, and can also deal with its own aging, damaged and degenerated cells.

It can be seen that the body's resistance and immunity are subtly different, but the two cooperate with each other, and the common purpose is to protect the health of the human body, which is of great significance to life safety.

Immunity refers to the body's ability to resist the invasion of external pathogens (such as viruses, bacteria, etc.) and protect its own health. The stronger the immunity, the better the body can resist various diseases and stay healthy.

Immunity is mainly maintained by the body's immune system. The immune system is an effective defense system in the human body against foreign invaders, which is composed of a variety of immune cells and immune molecules. Immune cells include white blood cells (such as T cells, B cells, etc.) and macrophages. Immune molecules include antibodies, etc.

The body's immunity can be affected by factors such as lifestyle, diet, exercise, etc. Lifestyle factors include maintaining good hygiene habits, such as washing hands frequently and avoiding contact with disease sources; Dietary factors include eating more fresh fruits and vegetables, eating enough protein, eating foods rich in vitamin C, etc.; Exercise factors include exercising properly, maintaining a good mental state, etc.

In addition, effective health care methods can also be used to increase immunity. For example, the use of immune boosters, health care food, etc.; Get vaccinated and seek medical attention promptly.

Human immunity refers to the body's ability to fight diseases and infections. It is a defense mechanism provided by the complex mechanisms of the immune system. The immune system is a complex network of cells, organs, and molecules designed to recognize, attack, and eliminate invading pathogens (e.g., bacteria, viruses, fungi, and parasites) as well as abnormal cells (e.g., cancer cells).

There are two main aspects of human immunity:

1.Natural immunity (innate immunity): This is the body's innate immune response and the first line of defense. Natural immunity quickly identifies and fights off pathogens through the mucosal barrier, macrophages, inflammatory responses, and more.

2.Acquired immunity (adaptive immunity): This is the body's immune response that gradually develops after exposure to pathogens.

Acquired immunity is achieved through lymphocytes (such as B cells and T cells) and antibodies in the immune system. It identifies and remembers previously exposed pathogens, allowing for more effective response to the next re-exposure.

The strength of the body's immunity depends on a variety of factors, including genetics, age, lifestyle, nutritional status, environmental factors, etc. Maintaining a healthy immune system is very important and can be boosted by:

Eat a healthy diet: Eat enough vitamins, minerals, and antioxidants, including fresh fruits, vegetables, whole grains, and protein.

Exercise regularly: Moderate physical activity can boost the function of the immune system.

Get enough sleep: Getting enough sleep can help boost immunity and restore your body.

Healthy lifestyle habits: Avoid smoking, limit alcohol intake, maintain an appropriate weight, and manage stress.

Vaccinations: Receiving proper vaccinations boosts the immune system's protection against specific pathogens.

Human immunity refers to the body's ability to fight off the invasion of foreign pathogens. When our body is infected by microorganisms such as bacteria, viruses, fungi, etc., the immune system produces a series of reactions to protect the body from damage. These reactions include the proliferation and differentiation of white blood cells, the activity of phagocytic cells, the production of antibodies, etc., and ultimately the formation of immune defense mechanisms against specific pathogens.

In addition, in daily life, developing good eating habits, moderate exercise, and maintaining mental health can all help improve the body's immunity.

Immunity and resistance are both part of the endocrine system, a relationship that assists each other, and most people basically think of the two rounds as the same.

The main differences are:

1. Immunity refers to the fact that when the germ invades, immunity is to actively identify the harmful nature of the dangerous jujube and eliminate the harmful foreign punishment of the paulownia dismantle.

2. Resistance is the ability of the immune system to resist external germs.

Both are designed to protect human health.

Immunity and resistance are the ability of our body to fight against viruses, and immunity and resistance ensure the normal progress of human life activities. So what's the difference between immunity and resistance?

1. The meaning is different. Immune cavity is the body's own defense mechanism, which is the body's recognition and elimination of any foreign body (virus, bacteria, etc.) that invades from outside. Immunity has the ability to deal with aging, damage, death, degeneration of its own cells, as well as to recognize and process mutant cells and virus-infected cells in the body.

Resistance refers to the system under the control of the central nervous system, the various systems of the human body cooperate and cooperate closely to ensure the normal progress of human life activities.

2. The functions are different. The function of immunity is to defend against infection and make the body resistant to infection by pathogenic microorganisms; It also has the function of removing senescent, dead, and damaged cells in the body in a timely manner, and the function of identifying and removing abnormal cells caused by mutations in the body at any time.

The resistance has unique immune organs for the human body, including the thymus, spleen and lymph nodes, as well as the humoral immune system (B cell system), cellular immune system (T cell system), phagocytic system and complement system, and realizes the body's immune defense function through its own way.

In general, the meaning and function of immunity and resistance are different, and I believe you will have a better understanding of the concept of the two after reading them.
