We should all feel that our bodies are asymmetrical. When I buy shoes, I often feel that two shoes feel different when I wear them. In fact, our two feet look different. Why is this? Let's have a look with Sihai.

Why is person's body right and left asymmetry? Cause analysis of asymmetry between left and right sides of human body

From the appearance, the human body has perfect symmetry from five senses to limbs. For example, one hand, two legs, one pair of ears, two eyes, etc.

If you enter the interior of the human body, you will find that many internal organs are not symmetrical: the heart is located on the left side of the body, while the liver is on the right side of the body; the left bronchus is long and thin, and the direction is relatively flat; the right bronchus is thick and short, almost vertical.

Back out of the body, the area of the left foot touching the ground is usually larger than that of the right foot; some people have double eyelids in one eye and single eyelid in the other eye; one eyebrow is high and the other is low; one side has dimples when smiling, but the other side is not. These are normal asymmetric phenomena. If there is abnormal asymmetry, it is often a sign of illness. For example, only half of the body sweats, which is a precursor to stroke or hemiplegia.
