The chest cavity houses numerous organs and structures vital for bodily functions. While many organs are centrally located or extend across both sides, specific structures are predominantly found on the right, influencing sensations in that region.
The Liver’s Location
The liver, the body’s largest internal organ, is primarily located in the upper right portion of the abdominal cavity. Its substantial size means it extends upwards, beneath the diaphragm and shielded by the lower right rib cage. Sensations or issues originating in the liver can often be felt in the lower right chest area.
This organ performs over 500 functions, including detoxifying harmful substances from the blood and producing bile, which is essential for fat digestion. It also plays roles in regulating blood sugar levels, synthesizing various proteins, and helping with blood clotting. Any inflammation or discomfort within the liver can manifest as pain or pressure in the right chest region.
Other Important Structures
Beyond the liver, several other significant structures influence the right side of the chest. The right lung resides within the right pleural cavity and is responsible for oxygen exchange. It is encased by a protective, double-layered membrane called the pleura, which allows for smooth, friction-free movement during breathing. Issues affecting the right lung or its surrounding pleura can cause discomfort or pain in the right chest, often worsening with deep breaths.
Beneath the lungs, the diaphragm is a dome-shaped muscle that separates the chest cavity from the abdomen. It serves as the primary muscle for respiration, contracting to draw air into the lungs and relaxing to expel it. Problems with the diaphragm, such as irritation or strain, can lead to pain in the lower right chest area.
The gallbladder, a small, pear-shaped organ, is situated directly beneath the liver in the upper right abdomen. Its main function is to store and concentrate bile produced by the liver, releasing it into the small intestine to aid in the digestion of fats. Conditions affecting the gallbladder, such as gallstones, can cause pain in the upper right abdomen that may radiate to the right chest or shoulder.
Understanding Symptoms and When to Act
Discomfort in the right chest area can manifest as sharp, dull, or aching sensations. This pain may worsen with movement, deep breathing, or specific activities. While many causes are minor, certain accompanying symptoms suggest the need for prompt medical attention.
If chest pain is accompanied by shortness of breath, fever, persistent pain, changes in bowel habits, or jaundice, seek evaluation. Other concerning signs include sweating, nausea, dizziness, or pain spreading to the back, neck, jaw, or arms.
