In general, its main feature is that it is divided into neurotoxoids and non-neurotoxins, so neurotoxins are relatively very fast, and non-neurotoxins are slower.
-
It is characteristic of the release of poisons in the human body. It should spread to all parts of the body with the bloodstream, and this method is very difficult, so we should not easily come into contact with these toxic substances.
-
I think this should be the face will become lighter, and there will be sweating, these are the two most obvious characteristics, two characteristics are not right, and one feature is the whole body is weak and weak, this should be the most obvious three characteristics If it is solved, please give a thumbs up and, thank you.
-
The distribution of substances in the human body is characterized by the first entry into the bloodstream through the intestines, so what about the blood? Distributed throughout the body.
-
Toxins in the human body are mainly found throughout the body through the bloodstream.
-
Generally, there are the following routes: respiratory tract, **absorption, ingestion with food and water, and traumatic contamination.
-
Digestive tract Respiratory tract **mucosa.
-
To or under the wrong description of the process of poison in the body is () aPoisons mainly enter the human body through the digestive tract, respiratory tract, and mucous membranes.
b.Respiratory absorption is the fastest way to exert the poison.
c.The metabolism of the poison is mainly in the liver.
d.All poisons are metabolized and the toxicity is reduced.
e.The poison is excreted mainly through the kidneys and intestines.
Correct answer: d
-
The three ways industrial poisons enter the human body are generally through the digestive tract and the respiratory tract.
Gases and aerosols in the production of toxic substances.
Dust, smoke, fog and other poisons can enter the human body through the respiratory tract, mainly invading the bronchi, alveoli and other parts of the human body, after metabolism, some poisons may enter the blood circulation through the alveolar wall.
Affects all systems throughout the body.
Direct contact with some chemicals, such as aromatic compounds.
Nitro compounds, mercury, etc., can enter the human body through direct contact and cause harm.
Productive toxins can also enter the body through the digestive tract, mostly due to eating contaminated food or poor hand hygiene.
and cause infection.
If the work you are engaged in will produce those poisons, you must do a good job of protection at work, try not to let ** contact, and then you must wear a mask or gas mask at work.
-
Digestive tract absorption (swallowing), respiratory absorption (gas or dust inhalation) and percutaneous absorption (** infiltration).
Swallowing is well understood, including accidental ingestion and toxic residues in food.
Inhaled gases such as ammonia, chlorine, hydrochloric acid, etc. can cause acute respiratory tract damage, and dust can cause diseases such as pneumoconiosis.
Some substances can penetrate into the human body even on the surface of the good **, such as mercury and mercury, and some can be absorbed by ** after mixing with substances that promote penetration (such as oleic acid).
-
Respiratory, Digestive tract, **.
a) Respiratory.
Gases, vapours and aerosols are mainly inhaled through the respiratory tract. Through the alveolar membrane (70 m2), inhalation enters the large circulation.
Influencing factors:1Concentration 2blood gas partition coefficient; It is highly soluble in water (ammonia) and absorbed in the upper respiratory tract, and low in water solubility (nitrogen dioxide) in the deep part.
4.Meteorological conditions 5Respiratory clearance function.
ii). For example, organophosphorus compounds, aromatic amino and nitro compounds, organometalls (tetraethyl lead), etc., can enter the body through **.
Influencing factors: oil-water partition coefficient; poison concentration and viscosity; Humidity and temperature.
c) Digestive tract:
Insoluble dust enters with the pharynx. Common in accidents; Such as poor hygiene habits, etc.
-
Hello It mainly enters the human body through the respiratory tract, digestive tract, **.
-
The poison that enters the human body is repentant, and its distribution and () are related to the disturbance of the year.
a.Local blood flow.
b.The pH of bodily fluids.
c.Organizational affinity.
Molecule. Correct answer: ABC
Sodium bicarbonate and carbonic acid are both buffering substances in the human body, and they are called buffer pairs, and I personally believe that the small amount of sodium bicarbonate that the human body needs normally does not need to be ingested from outside the body.
Calcium is not broken down.
Much more, both sugars and lipids can be converted into proteins, but very little is converted into lipids. 1。Self-protein breakdown, 2. >>>More
