Question

What organs are located on the left side of your body below the ribcage?

Answer 1

In most vertebrates, the rib cage is an arrangement of ribs linked to the spinal column and sternum in the thorax that encloses and protects critical organs like the heart, lungs, and major vessels. The thoracic cage, which includes the rib cage and sternum, is a semi-rigid bony and cartilaginous structure that surrounds the thoracic cavity. Ribs are classified according to their location and relationship to the sternum. True ribs are those that articulate directly with the sternum, while false ribs are those that do not.

Complete answer:
Your rib cage is made up of $24$ ribs, $12$ on the right side and $12$ on the left. Their purpose is to keep the organs under them safe. This includes your heart, left lung, pancreas, spleen, stomach, and left kidney on the left side.
The spleen, pancreas, stomach, left adrenal gland, left kidney, left ureter, left Fallopian tube (female), left ovary (female), left testis (male), descending colon, sigmoid colon, rectosigmoid colon, and rectum are all on the left side of the body behind the rib cage.

Additional information:
The rib cage is a part of the respiratory system in humans. It protects the lungs by enclosing the thoracic cavity. The muscular diaphragm at the bottom of the thoracic cavity contracts and flattens during inhalation, while the intercostal muscles contract and raise the rib cage up and out.

Note:
The rib cage is made up of long curving bones called ribs. The protective cage of the thorax is formed by the ribs, which are made up of $24$ bones in $12$ pairs. All ribs are linked to the thoracic vertebrae posteriorly and are numbered one through twelve. The thoracic internal organs are protected by the ribs. They connect to the vertebral column in the back and end in cartilage in the front.
