How does lead affect the human body?!
Question: Please describe the effects that lead has on the Human body.
Answers: Please describe the effects that lead has on the Human body.
Most of the dysfunctions produced by the absorption of lead are due to lead's ability to mimic and inhibit the actions of calcium. In humans the lead is directly absorbed, distributed, and excreted. Once in the bloodstream lead is distributed to three main compartments: blood, soft tissue (kidney, bone marrow, liver, and brain), and mineralized tissue (bones and teeth). Lead effects children and adults in different ways. Low lead levels in children can cause the following side effects:
Nervous system and kidney damage.
Learning disabilities, attention deficit disorder, and decreased intelligence.
Speech, language, and behavior problems.
Poor muscle coordination.
Decreased muscle and bone growth.
Hearing damage.
Seizures, unconsciousness, and death
In adults high levels of lead in their systems can cause the following:
Increased chance of illness during pregnancy.
Harm to a fetus, including brain damage or death.
Fertility problems (in men and women).
High blood pressure.
Digestive problems.
Nerve disorders.
Memory and concentration problems.
Muscle and joint pain. (4)
Once lead enters the body it interferes with normal cell function and physiological processes. Some of the physiological effects of lead include harm done to the peripheral and central nervous system (PNS, CNS), blood cells, metabolism of vitamin D and calcium, and reproductive toxicity. The nervous system seems to be the most sensitive to lead poisoning.
Several factors must be looked at in order to find the harmful health effects produced by lead:
How much lead is present in the organ system?
How long has the lead been present?
Is the organ system at a time in its development when it can be affected by lead?
lead poisoning happens slowly. The lead that is taken in daily, mounts up in the tissues, especially the bones.Sometimes bone releases its lead. This may be when the person has a disease, for example osteoporosis, or sometimes during pregnancy and lactation. During pregnancy lead is transferred from the mother to the developing infant. Because lead freely crosses the placenta, the mother's blood lead amounts determine how much lead reaches the foetus.
hope this shud help....
Long term lead exposure can cause brain damage. Symptoms that develop include a metallic taste in the mouth, abdominal pain and loss of appetite
It can prevent your organs from getting oxygen.
