Cyanide is a broad-spectrum poison because the reaction it inhibits is essential to aerobic metabolism; COX is found in many forms of life. [28] However, susceptibility to cyanide is far from uniform across affected species; for instance, plants have an alternative electron transfer pathway available that passes electrons directly from ...
The blood of people killed by blood agents is bright red, because the agents inhibit the use of the oxygen in it by the body's cells. [2] Cyanide poisoning can be detected by the presence of thiocyanate or cyanide in the blood, a smell of bitter almonds, or respiratory tract inflammations and congestions in the case of cyanogen chloride ...
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. [2] Symptoms may include abdominal pain, constipation , headaches, irritability, memory problems, infertility , numbness and tingling in the hands and feet. [ 1 ]
The human body contains many types of cells and a human can be killed by the loss of a single type of cells in a vital organ. For many short term radiation deaths (3–30 days), the loss of two important types of cells that are constantly being regenerated causes death.
Poisoning is the harmful effect which occurs when toxic substances are introduced into the body. [1] The term "poisoning" is a derivative of poison, a term describing any chemical substance that may harm or kill a living organism upon ingestion. [2] Poisoning can be brought on by swallowing, inhaling, injecting or absorbing toxins through the skin.
Affected cells then proceed to blebbing, and this is followed by pyknosis, in which nuclear shrinkage transpires. [21] In the final step of this pathway cell nuclei are dissolved into the cytoplasm, which is referred to as karyolysis. [21] The second pathway is a secondary form of necrosis that is shown to occur after apoptosis and budding. [21]
The human body has protective mechanisms in place to prevent excess free ferric iron from circulating the body. When being transported throughout the body, iron is bound to an iron transporting protein called transferrin to prevent iron from being absorbed into different cells. [6] Any excess iron is stored as ferritin in the liver. [6]
Some toxic effects do not necessarily cause permanent damage and can be reversible. However, some toxins can cause irreversible permanent damage. Depending on the intensity of the poison of the substance it [2] can affect just one particular organ system or they may produce generalized toxicity by affecting a number of systems. A variety of ...
