The human body has many homeostatic mechanisms that keep us healthy and comfortable. The human body is designed to be both anatomically as well as physiologically able to adapt to changes in its environment. Ever wondered what keeps us alive. What keeps us alive? Many systems and organs work together to keep the body alive.

What keeps us alive

The human body is able to do 10 amazing things that keep you alive.

1. Every minute, your skin sheds between 30,000 and 50,000 skin cells. This mechanism is essential for getting rid of harmful organisms and dead skin cells on the surface. Only the eyes shed. Skin that sheds is quickly replaced.

2. A woman’s body organ is damaged while she is pregnant. The stem cells are sent by the baby to repair damaged organs.

3. Normal body temperature for humans is 37 degrees Celsius. The body will die if it goes above or below 37 degrees Celsius. The body can do a number of things to maintain its temperature regardless of the temperature outside, including shivering and sweating.

4. The stomach secretes acid that can damage the stomach lining. Your body produces a new stomach lining each 3-4 days.

You forget some information in order to protect yourself from emotional stress and information overload. This helps you think faster and better assimilate information.

6. Self-healing is a natural ability of the body. The bleeding stops instantly in minutes if you get cut or hurt. The destroyed cells immediately grow back. It is important to note that we would all have died if this mechanism had not been in place.

How does the body respond in extreme cases of starvation? The body uses glucose and glycogen first to keep it going. It uses glucose and glycogen for 6 hours before switching to fats, ketone bodies and proteins. This mechanism could help you to survive hunger for as long as 70 days. This depends on factors such as weight and fat content.

8. When faced with a situation that could be life-threatening, the body secretes adrenaline and cortisol. This is called an acute stress reaction. This reaction increases your energy levels and gives you an extra boost of strength. This is a vital response in a fight or flight situation.

9. The body is able to identify and destroy pathogens which have previously attacked the body. This is called acquired immunity. You can develop acquired immunity over the course of your life. It can be acquired through a vaccination, an exposure to disease or from another person’s antibody (immune cells that fight infection).

10. The liver plays a vital role in the body. It is responsible for many metabolic and homeostatic processes. If part of the liver is removed because of injury, disease or surgery, it can regrow. Isn’t that amazing? It can grow to the perfect size for the organ it is in.

11. Your blood delivers oxygen and vital nutrients to your organs every second. The blood also removes waste from your body. Flowing blood can also be used to cool or heat you, depending on the situation.

 

In conclusion, we should always acknowledge our body’s amazing abilities. Thanks!
