How Complicated is the Human Body

The human body is full of complications. It is so complicated that you can’t study it within a single day and rather it takes a time span of years and ages to be able to study it completely. It is much easy for one these days to study the description of human body put forward by researchers, but in olden days when there were no researches made over this topic, it was rather a big job to find or reveal something about the human body. Human body works like a machine where food and air is the fuel and our different organs of the body act as the parts of this machine. The structure of the human body along with its complexities can be explained as cell:-

How Complicated is the Human Body

1. From The Smallest Unit to Big Organs:-

The smallest unit in the human body is its cell. Many cells compose together to form a tissue and many tissues form together to form muscles. Each of the 6.8 billion people on earth is composed of a unique set of roughly 100 trillion cells and all of our bodies compose of the same composition where cells keep on making and damaging.

2. A Systematic Functioning of Sensory Organs:-

Human body works upon different kind of senses. This includes your sense of touch, sense of vision, sense of smell, sense of hearing, sense of taste etc. this is bought into a function by different sensory organs like eyes, nose, skin, ears, tongue etc. for example, if there is an approaching danger, you are able to analyze it by either seeing it or by hearing the noise that it makes. If there is a tasty food being made somewhere, you will come to know about it by just its smell.

3. Different Organs for Different Functions:-

In the human body, there are different organs for different functions and each of them has been further sub-divided into many sub parts. For example, heart pumps the blood, penis helps in urination, brain helps in thinking and taking decisions and similarly each and every organ has got its different function. If I give you an example of the way these organs have been further sub-divided, the best example will perhaps be the human brain, which is composed of different parts like cerebellum, cerebrum, mid brain, hind brain etc.

4. Breakdown of Energy:-

We take food through the mouth. There are two pipes connected with our mouth, one of which is for taking air to breathe and the other is for swallowing the food. When we are eating the food, wind pipe stays closed and when we are breathing, the food pipe stays closed. When we take food in mouth and start chewing it, the salivary glands immediately secrete saliva that gets mixed with food to make it easy to be swallowed and then when the food reaches inside the body, different digestive enzymes act on it to break it down into simpler components. The energy is taken from this food and thus our boy is able to function properly.

5. The Excretion after Intake:-

I told you earlier that we have different organs and systems in the body for each and every function.  When the air is taken in, it is taken with the help of the respiratory system. When we take food, it is taken from esophagus or food pipe which is a part of the digestive system. When food is broken down into small components, the same digestive system is responsible for that and once energy is taken from the food that reaches our body, there are some waste products left which are eliminated by excretory system.

Human body is difficult and complex to understand as each of these systems can be further sub-divided into many sub-components. There are also some other systems like nervous system which is related to brain, endocrine system, Integumentary system (Exocrine system), Lymphatic system, Muscular system or skeletal system and Renal system which is also called the urinary system.
