The 3 systems where the effects of lead are more dangerous are?

• A. The nervous system, blood and kidneys
• B. The digestive system, liver and heart
• C. The respiratory system, lungs and skin
• D. The circulatory and immune systems

Answer: (A)

Lead exposure most dangerous effects appear in the nervous system, the blood-forming (hematologic) system, and the kidneys. The developing nervous system in children is especially vulnerable, with potential irreversible cognitive and behavioral damage from exposure. Lead also disrupts enzymes needed for heme synthesis, leading to anemia and significant blood-related problems. Additionally, lead can injure the kidneys, particularly the proximal tubules, causing nephrotoxicity. Other organs can be affected, but these three are the primary sites where lead’s harm is most severe and clinically significant.
