Who can answer this question: 'How many holes are there in the human body?'

Don't think it's easy. The answer is not simply that men have 8, women have 9 with eyes, nose, ears, genitals. In fact, there are lots of sweat glands, hair follicles on the body, and if so, exactly no one can give an answer.

1. The human body and huge numbers startle you
2. 5 parts of the human body become redundant and useless due to evolution
3. If stretched all the way, how big are the human organs?

The distribution of hair and hair on the body depends on gender, age, hair color. The brown-haired person has a higher density of hair follicles in red-haired people.

Based on the study of hair follicles / hair follicles to differentiate human and other primates of anthropologist Adolf Schulz, we can give an estimate of the number of hair follicles / hair on the body. human body.

According to Adolf Schulz's study, on average humans and primates have the same number of hair follicles / hairs, about 300 per cm2. The density of hair follicles in the chest is the smallest, only one capsule per 1 cm2. Accordingly, if only based on the average density of hair follicles / hair, the human body has 5,000,000 holes.

In fact, in addition to hair follicles, people also have sweat glands. According to the results of a recent study, it is estimated that humans have a total number of sweat glands of about 3 million.

Summing up, the number of losses on the human body is a tremendous number compared to the estimate of any one of us.
