What Effects Does Smoking Have on the Spleen?

Smoking harms the body in many ways. Nicotine from cigarettes is absorbed into the bloodstream and can affect how the body's organs operate. The spleen is a peripheral organ not often discussed in relation to smoking, but it is at risk of damage.

Function

• The spleen is a major body organ that filters harmful or damaged red blood cells and unwanted bacteria from the blood.

Impact

• A study conducted by the Brookhaven National Laboratory concluded that nicotine affects several major organs in the body including the spleen by reducing the amount of the enzyme monoamine oxidase B (MAO B).

Features

• MAO B is responsible for breaking down chemical compounds that cause high blood pressure. It also breaks down dietary amines and neurotransmitters, having an effect on both the body and personality.

Results

• Study results showed a reduction of up to 46 percent of MAO B in the bodies of smokers, significantly reducing their ability to remain healthy.

Considerations

• The spleen is not considered a vital organ and other peripheral organs are able to handle many of the spleen's responsibilities if necessary. However the MAO B effects of nicotine impact the entire body's ability to function.
