How many cells do people consume per day? How many cells in the human body disappear in a day?

On average, about 70 billion cells die in the body of an adult returning to the human body, and even in an average child between the ages of 8 and 14, about 200.30 billion cells die every day.

In fact, these cells all die naturally, and new cells are produced in our body every day, and some cells die of natural aging. The average adult has a total of about 13 trillion cells in his body, and even if 70 billion die every day, it only accounts for the total number of cells.

Characteristics of human cells:

The cells of the lungs are constantly renewing themselves. However, the lungs have different cells that are updated at different rates. The renewal process of air bubbles or air sacs located deep in the lungs to exchange oxygen and gas is stable and takes about 1 year.

At the same time, the cells on the surface of the lungs must renew themselves every 2 to 3 weeks.

There are about 9,000 taste buds on the tongue that help us feel sweet, salty, bitter or sour. The taste buds themselves are a collection of cells on the surface of the tongue, each with about 50 taste cells. It usually takes only 10 days to 2 weeks for the taste buds to renew themselves.

70 billion human cells die every day, and all of these cells are removed by phagocytes. In fact, phosphatidylserine exists in the cells of the human body, and when the cell is still alive, it exists in the cytoplasmic membrane, but when the cell dies, it will run out of the cell, and send a signal to other cells in the human body, "The cell here is dead", and when the phagocytic cell receives the signal, it will come to deal with it.

Phagocytes are actually a very large family, and the familiar white blood cells actually belong to phagocytes. There are a lot of phagocytes in the blood of the human body, about 1000ml of blood, there are 6 billion phagocytic cells, which means that the 70 billion cells that the human body dies every day may not be enough for them to stuff their teeth.

When phagocytes receive the signal, they move away from the vicinity of these dead cells. Phagocytic cells are actually a very important part of the body's immune system, as long as they sense that there are substances that will cause harm to the body, they will carry out phagocytic behavior, mainly phagocytosis of some bacteria and viruses, but when the body has no problems, they will also take on the responsibility of dealing with dead cells.

Phagocytes may be able to be cleaned in a few minutes near these desired cells. Phagocytic cells have digestive enzymes that can break down all the dead cells and then excrete the remaining waste products from the body. The products of its decomposition can also provide certain nutrients to the surrounding cells, and the normal metabolism of the human body will also excrete a part of the waste products.

Although 70 billion cells die every day, 70 billion new cells are produced in order to maintain the balance of cells in the body. However, not all cells in the human body are normal apoptosis, and some of them are necrotic due to the influence of diseases, which will affect the health of the human body. In the process of cell turnover, phagocytes play a vital role.

It takes 500 trillion cells to make up a human body, and 5 million cells are cubic meters.

24 hours, i.e. 1440 minutes, 86400 seconds, 365 days in a year, 8760 hours, 525600 minutes, 31536000 seconds.

China has a land area of 9.6 million square kilometers (9,600,000), including Chinese mainland and its coastal islands.

China is the most populous country in the world, with a population of more than 1,400,000,000 (1.4 billion).

The world's largest ocean is the Pacific Ocean, which covers an area of 179,968,000 square kilometers (17,968,000 square kilometers).

The largest continent in the world is Asia, with an area of 4,400 (4,400) square kilometers.

The largest country in the world by land area is Russia, with an area of 17,075,870 (17,075,870) square kilometers.

It is widely accepted that the number of stars in the Milky Way is about 150 billion, that the solar system is about 10,000 light-years away from the center of the Milky Way, and that the average distance between stars near the solar system is at least 5 light-years, and one light-year is 9.46 trillion kilometers.

Human cells. It is the structural and functional unit of the human body. There are about 400,000-60 trillion cells in total, and the average diameter of the cells is between 10 and 20 microns.

With the exception of mature red blood cells, all cells have a nucleus that is the center that regulates cellular action. The largest are mature egg cells, with a diameter of more than millimeters; The smallest is platelets, which are only about 2 microns in diameter.

The lifespan of intestinal mucosal cells is 3 days, the lifespan of liver cells is 500 days, and the lifespan of nerve cells in the brain and bone marrow is several decades, which is almost the same as the lifespan of the human body. Some white blood cells in the blood only live for a few hours.

In the entire human body, 100 million cells die every minute. The most amazing thing is that the nerve cells of the brain transmit nerve impulses at a speed of more than 400 kilometers per hour, which is equivalent to half the speed of a 777 aircraft. Answer.
