Organs located on the left side of a normal human body include the left hemisphere of the brain, the left lung, the heart and the stomach, according to Inner Body. Additional organs located on the left side include the left kidney, the spleen, and sections of the large and small intestines.
Roughly the size of a closed fist, the heart is a critical part of the cardiovascular system. The system is responsible for transporting nutrients, cellular waste, oxygen and hormones to varied sites around the body, explains Inner Body. The heart is divided into four chambers: the left ventricle, the right ventricle, the left atrium and the right atrium. Ventricles are larger and stronger, as they pump blood away from the heart. In contrast, the atria have thinner and less muscular walls because the role they play, receiving blood, is less taxing.
The spleen is ensconced between the diaphragm and the stomach. Part of the body's immune and lymphatic systems, the organ filters harmful microorganisms out of the blood. Additionally, the spleen stores blood and platelets, elements that play a critical role in blood clotting, notes Inner Body. Unlike the heart, the spleen is not a vital organ; its functions can be performed by the liver, red bone marrow and lymph nodes.
Individuals suffering from situs inversus have the spatial orientation of their organs reversed, reports The New York Times. Those with this condition have hearts and spleens located on the right side of the body.
