Oxygen is the most important air molecule for the body because oxygen is moved from the air to the body cells. In order for this to happen, the body has several systems that work together such as the respiratory system, the cardiovascular system and the muscular system.
These systems work together to move oxygen through the body. There are several different parts that are included in the respiratory system.
Breathing is an involuntary movement, which means that we breathe without thinking about it. The respiratory system plays a huge role in breathing, and it is connected to the heart and circulatory system through the cardio-pulmonary circulatory process.
This process is what the body uses to make sure that oxygen and carbon dioxide are in a perfect balance.
The respiratory system uses more than the lungs to breathe. First, the trachea, or the windpipe, is a tube that delivers the air from the lungs and is also used to help keep the lungs healthy.
When we breathe air in, this air contains different things such as dust, bacteria, viruses and more. The air is dry and cool, and it travels from the nose to the throat and then down through the trachea where it is cleaned, moistened and warm to enter the other parts of the body.
The larynx is another part of the respiratory system and it helps you to talk. The larynx is part of the respiratory system that helps make sounds.
Cords in the larynx stretch to the vocal folds and when someone talks or sings and air is exhaled from the lungs, the vocal folds vibrate, and this is what causes there to be sound. Don’t forget the tongue, lips and teeth also help you to sing and talk!
Behind the chest are two hollow tubes that the trachea divides into and these tubes go into the lungs and then change to even smaller tubes. The smallest tubes have to be looked at with a microscope and they have sacs at the end, and they have very thin walls.
When a person breathes in or inhales, oxygens passes through these thin walls easily, and it goes into the blood. The red blood cells then carry the oxygen to other parts of the body while the carbon dioxide also passes through the walls so that you can exhale it.
The musculoskeletal system plays a huge job in breathing because your rib muscles and the diaphragm helps your body take air in and let air out by moving a certain way in the body. The diaphragm is a muscle that helps with breathing.
Your body needs oxygen to help make energy from sugar. If the body does not have oxygen, it cannot make energy. The body cannot live without oxygen.
The body has three stages of breathing. The first stage is inhaling the oxygen into the body. With this stage, the diaphragm expands, and the lungs expand with air that has entered through the nose and mouth.
The second stage is the gas exchange that happens in the lungs. With this stage, air enters the lungs and oxygen from the inflated lung moves from the alveoli into the capillaries as carbon dioxide moves from the capillaries into the alveoli.
The last stage is exhaling carbon dioxide out of the body. The diaphragm muscles relax and the pressure around the lungs pushes the air out of the body where carbon dioxide is released from the body, traveling from the alveoli to the bronchiole to the bronchi, up the trachea and out through the nose and mouth.
