The Journey of a Molecule

The Journey of an Oxygen Molecule (3)

Your lungs are two sponge-like organs that fill with air when you inhale, and you exhale carbon dioxide. The contracting and expanding of the lungs is controlled by the diaphragm, the only muscle in the Respiratory System. The process of breathing is called respiration. Once inside the lungs, oxygen is forced into little holes called alveoli, which are covered in capillaries that cover them. The capillaries bring oxygen into the bloodstream, where it is delivered to other bodily systems.

After that, the air travels into the larynx, or voice box. The larynx controls your vocal cords, which allow you to speak and communicate with voice. If you rub a finger up and down the front of your throat, the ridges you feel are the outside of the larynx. The oxygen now travels into the trachea. the trachea is the passageway for air traveling from the larynx to the lungs. the trachea will then split up into two tubes called the bronchi. Once the air travels through the bronchi and bronchioles, it will enter your lungs.

An oxygen molecule begins in the atmosphere and the surrounding air. It is enhaled through either the mouth or the nose (the nose mostly). At the same time the ribcage expands to open up the path for air.

After this the air is filtered through the wind pipe and naval cavities in order to expel carbon dioxide and leave only oxygen in the body.

Facts of an oxygen molecule

1. All living things on the planet require oxygen to survive.

2. Approximately 2/3 of the mass of the human body is oxygen.

3. Oxygen is a gas that is colorless, odorless and tasteless. It is composed of two oxygen elements.

4. Discovered By: Joseph Priestly, Carl Wilhelm Scheele

5. Discovery Date: 1774 (England/Sweden)

How Much Oxygen we Take in

After oxygen has been through the respiratory system it will fill the needs of other bodily systems such as the muscular system. The more activity a certain muscle is doing at the time requires a higher supply of oxygen. In archery required muscles to pull back a bow are the

* Upper Back and Shoulder Muscles - to draw the bow

* Upper and Lower Shoulder Muscles - to control the bow

* Arm Muscles - to extend the bow arm

* Finger muscles - to hold the bowstring

* Upper and Lower Leg Muscles - to control balance

* Lower Back and Waist Muscles - to control a steady stance

Breathing patterns in Archery

The average amount of air an adult inhales and exhales somewhere around 7-8 liters of air per minute, in an hour it is near 11,000 liters. A person who is exercising obviously uses a lot more oxygen than that. You could determine how much air is moving through your lungs by exhaling into a plastic bag of known volume at each breath and seeing how long it takes to fill the bag.

The Role of the Respiratory System

Option 1

1. A deep diaphragmatic settling breath should be taken prior to raising the bow.

2. With the focus on the target a normal breath, using diaphragmatic breathing, is taken between Raising the Bow and Set-Up. This not only has a settling effect, but will also lower the center of gravity. Further, it will help the archer to increase their focus and aids in not rushing the draw.

When an archer becomes more advanced and has acquired a good technique the breathing cycle can be modified as follows.

Option2

1. A deep diaphragmatic settling breath should be taken and exhaled before raising the bow.

2. While raising the bow inhale deeply and naturally, employing the diaphragmatic breathing technique, which will create a natural feeling of gaining strength.

What is the Respiratory System?

The cells in our body need oxygen to survive and it is the respiratory system's job to make sure our cells get it. The respiratory system takes up oxygen molecules from the air we breath and expels the unwanted carbon dioxide. when we inhale oxygen and exhale carbon dioxide, this exchange of gases is the respiratory system's means of getting oxygen to the blood.
