Important Systems of the Human Body

Breathing is a mechanical process consisting of two phases:

Inspiration or inhalation or intake of fresh air into the lungs.
Expiration or respiration or out of impulse and air consumed out of the lungs.

Breathing is associated with the existence of life itself. The lung itself cannot pull air or push it out. Therefore, human breath with the suction pump mechanism. The chest wall and diaphragm act as large pumps in moving air in and out of the lungs. In humans when breathing normally, 500ml of air moves in and out of the lungs every time you breathe. The mechanism of breathing: We know that breathing consists of two phases, namely breathing in or inspiring and breathing out or expiring. Many factors are involved in the mechanism of breathing, eg

Contractions and relaxation of intercostal muscles between the ribs bring changes in the position of the ribs and sternum. When these muscles contract, the ribs lift and move up and forward and when these muscles relax, the ribs settle and move in and back. The breastbone also moves in and back.
Contraction and relaxation of the diaphragm muscles bring changes to their shape. When these muscles contract, the diaphragm becomes like a dome or convex
The elasticity and elasticity of the lungs causes expansion and contraction. They expand when breathing and contract during breathing.

Breathing or inspiration: In humans, inspiration is an active process. During inspiration, the intercostal muscles between the ribs contract and pull the rib cage forward and outward, pushing the sternum further from the spinal column. With the contraction of the intercostal muscles and diaphragm, the size of the thorax as a whole increases and the inner pleural cavity enlarges. Because the pleural cavity is closed therefore their enlargement tends to create a partial vacuum in it. Lungs are elastic and communicate with the atmosphere through the airways (trachea, bronchi). As soon as the pressure around the lungs is lowered, air flows in through the trachea and bronchi. In this way the lungs expand to fill the pleural cavity and the pressure on the inner and outer thorax is equalized. Thus the mechanism of human breathing is the mechanism of the suction pump. The lungs are made to expand and contract with the movement of the ribs and diaphragm.

Breathing or expiration: Expiration in humans is usually a passive process. But in heavy muscle training, expiration also becomes active. During expiration, the intercostal muscles of the ribs relax, the ribs move downward and inward. Thus the size of the chest cavity is reduced from side to side. The breastbone reaches its original position, reducing the size of the chest cavity from front to back. At the same time the muscles of the diaphragm relax so that the diaphragm takes a dome-shaped position. So by relaxing the muscles of the diaphragm and intercostal muscles, the overall size of the chest cavity decreases. Reducing the size of the thorax puts pressure on the lungs. The lungs themselves are very elastic and tend to return to their original size. When the lungs are pressed, dirty air in them is expelled or expiration occurs….

Incredible Systems

The human body is a complex organization of complementary systems that work together to make the body function properly. Every complex system has individual parts that must function properly so the system can work. In this article you will find a brief overview of some of the body’s extraordinary systems.

Framework System

The main work of the framework is to provide structural support for our bodies. Without bones, our body will collapse into a pile of skin, organs, and muscle tissue. Bones provide a place for the muscles to stick so that we can move. In addition, the skeletal system helps protect the fragile internal organs and tissues of our body.

The skeleton of an adult human has an average of 206 bones joined by ligaments and tendons to form a protective and supportive skeleton for the attached muscles and soft tissue underneath.

Digestive system

The digestive system is a group of organs that work to break down the chemical components of food through the use of digestive juices into important nutrients, which can be absorbed to produce the body’s energy. This system also builds and replaces cells and tissues, which constantly die.

Bloodstream system

The circulatory system is responsible for transporting materials throughout the body. It transports nutrients, water, and oxygen to billions of cells in your body while carrying waste such as carbon dioxide produced by the body’s cells. The circulatory system is an extraordinary highway that moves through your entire body that connects the totality of your body’s cells.

The circulatory system is divided into three main parts:

Heart

Blood

Blood vessel

Respiratory system

The respiratory system carries oxygen to the body through inhalation and removes carbon dioxide as you exhale. This system includes the nose, trachea, and lungs. When you breathe, air enters your nose or mouth and goes down a long tube called the trachea. The trachea splits into two bronchial tubes, or primary bronchi, which have full access to the lungs. The primary bronchial branch becomes a smaller bronchial tube, or bronchiole. Bronchiole ends in the alveoli, or air sac. Oxygen follows this pathway and passes through the walls of the air sac and blood vessels into the bloodstream. At the same time, carbon dioxide is passed to the lungs and removed from the body when exhaled.

Nervous system

Your nervous system is a system of command and control of the body. His job is to communicate by sending and receiving messages. Your nervous system controls thoughts and movements. As part of the nervous system, you have:

Brain Center – Command

Spinal cord

Neurons – Bring electrical messages which are the “language” of the nervous system.

The body also has an additional system that we haven’t mentioned here. Each of these ‘body’ systems consists of smaller complex systems. Even the simplest cell in the body itself is a complex system.

How did this complicated system appear?

It’s easy to think that this system is designed by intelligence that is far greater than ourselves. It is easy and logical to believe because we see this in our daily lives. Complex systems such as personal computers, TVs or DVD players are never the result of accidents. They are always the result of intelligent minds that manipulate and produce them.

Evolutionists have adopted a dogmatic belief system that affirms humanity, and all animal life in this case, evolved from primitive beings. Evolutionists show us a picture of this development when a monkey turned ape and finally from apes to modern humans. We have all seen these photos, which are considered one of the icons of evolution. These images make evolution seem simple. An ape looks like a human so it makes sense that they are one of our ancestors, right? Unfortunately, many people take this simple explanation at face value without questioning logic. However, as stated above, life is more than just this simple development. Life has a surprising complexity when you study the molecular level. Every living organism has many systems that have been engineered with extraordinary precision.

But many people prefer to believe that this complex system is the result of a series of random accidents.

In essence, the theory of evolution states that every complex system evolves through small changes in organisms over a long period of time.

Those who refer to the theory of evolution, no matter what is stated by evidence, have come up with various explanations for this scenario, but no one has passed the test using logic as the main indicator. The explanation of dogmatic evolutionists makes no logical sense and they also disagree with scientific knowledge, as we know. They are also not in accordance with the world that can be observed around us.
