What are the ways for poisons to enter the body, and what are the ways for poisons to enter the body

The way the toxin enters the body is also inseparable from the way our human body communicates and exchanges with the outside world, there are three main ones, the first is through our hair contact, absorption into the body, the second through our respiratory tract, the third through our mouth, or through the end of our digestive tract, through the rectum and so on into the body. Manifestations of intoxication.

The brother upstairs has already said it more comprehensively. Eat it in your mouth, breathe it in your nose, and penetrate it in. I would like to add two points: a wound with broken skin can become infected by contact with poison, and an eye can also become infected by contact with poison.

Eat it in your mouth, breathe it in your nose, and penetrate it in.

Respiratory tract absorption, ** absorption, digestive tract absorption.

Mouth, nose, ears. Industrial poisons, chemical substances that exist in small quantities in industrial production as raw materials, semi-finished products, finished products, by-products or wastes in industrial production, can have chemical or physicochemical interactions with the human body, destroy normal physiological functions, and cause dysfunction, disease, and even death.

After a small amount of chemical substances enter the human body, they can have chemical or physicochemical effects with the human body, destroy normal physiological functions, cause dysfunction, disease, and even death, and the substance is called poison.

These substances are called industrial poisons when they are present in industrial production as raw materials, semi-finished products, finished products, by-products or wastes.

There are three ways for toxic substances to enter the human body: absorption, swallowing, and inhalation. Absorption: through **, but also through wounds and infected wounds and conjunctiva.

Organic solvents, when accidentally exposed to them or rinsed with them, can be invaded by **, e.g., tetraethyl lead and toluene. Swallowing:

It enters the human body through the mouth. Inhalation: The main way for harmful substances to enter the human body, directly attacking the lung tissue.

There are three ways for toxic substances to enter the human body: absorption, swallowing, and inhalation.

1. Absorption. Through **, wounds and infected wounds and ocular conjunctival resorption. Organic solvents, when accidentally exposed to them or rinsed with them, can be invaded by **, e.g., tetraethyl lead and toluene.

2. Swallowing. This is rare in causing industrial illness and is more common in food poisoning.

It enters the human body through the mouth. When the lungs take action to expel the substances they reject, it is calculated that 50% are deposited in the upper respiratory tract.

and 25 substances deposited deep into the respiratory tract and eventually swallowed into the human body.

3. Inhalation. This is the main way for harmful substances to enter the human body, and it will cause harmful substances to bypass other human defense organs and directly attack the lung tissue. The lungs are an unobstructed way to bring substances from the external environment into the human body.

90% of industrial poisons enter the human body through this pathway.

There are three main ways for productive poisons to enter the human body:

Respiratory tractThe respiratory tract is the most common and dominant route. All productive poisons in the form of gases, vapors, dust, smoke and fog can invade the human body through the respiratory tract under the condition of improper protection. The entire respiratory tract of the human body absorbs the poison.

It is one of the ways for some poisons to be absorbed into the human body, and the poisons can be absorbed into the human blood through the pores, sebaceous glands, and sweat glands without damage.

In the production environment, the chance of poisoning caused by simple absorption from the digestive tract is relatively rare, often due to the direct use of contaminated hands to eat food with contaminated hands, resulting in poison entering the digestive tract with food. For example, when pesticides such as trichlorfon are packaged by hand, it may cause the poison to be absorbed through the digestive tract.

1) Soluble in fats and lipid-like, mainly aromatic nitro, amino compounds, metallolead compounds, etc. followed by benzene, toluene, xylene, chlorinated hydrocarbons, alcohols can also be absorbed by **.

2) Substances that can be combined with fatty acid groups in **, such as mercury and mercury salts, arsenic oxides and salts.

3) Corrosive substances, such as strong acids, strong alkalis, phenols and yellow phosphorus.

The main ways for productive poisons to enter the human body are the respiratory tract, ** and digestive tract.

Respiratory: This is the most common and main route. Poisons in the form of gases and aerosols (dust, smoke, fog) can enter the human body through the respiratory tract. Its main sites are the bronchial tubes and alveoli.

After the poison absorbed through the respiratory tract is inhaled into the alveoli, it can quickly enter the blood circulation through the alveolar wall, and the poison flows back to the heart with the blood of the pulmonary circulation, and then does not go through the liver for detoxification, that is, it directly enters the systemic circulation and is distributed throughout the body. Generally speaking, the higher the concentration of poison in the air, the smaller the dust poison particles, the greater the solubility of the poison in body fluids, and the faster the absorption through the respiratory tract.

In production, it is also more common for poisons to be poisoned by absorption. Some poisons can enter the body through intact**. **The absorbed poison generally reaches the dermis through the epidermal barrier and enters the blood circulation.

Fat-soluble poisons can be directly absorbed by **, such as aromatic amino and nitro compounds, organophosphorus compounds, benzene and homologues. Individual metals such as mercury can also be absorbed. Some gaseous poisons, such as hydrogen cyanide, can also enter the body at high concentrations.

When there is a lesion, the poison that cannot be absorbed completely** can also be absorbed in large quantities. In addition to the chemical characteristics of the poison itself, the concentration and viscosity of the poison, the area and location of contact, and the outside temperature and humidity will also affect the absorption.

There are many ways in which the poison is absorbed. If it is contact poisoning, the route of poison absorption can be ** or respiratory poisoning, and the absorption route is the lungs. In the case of oral poisoning, it can be absorbed through the mucous membranes of various organs of the respiratory system, including the esophagus, stomach, small intestine, large intestine.
