First you breath in air (which is not pure oxygen, only about 19% is oxygen) which goes to the lungs. The lungs have a huge surface area (the size of a football field!) covered in capillaries which blood flows though. The oxygen from the air is absorbed in the capillaries and is transfefred to the blood. The blood releases the waste Carbon Dioxide into the lungs which is breathed out.

The path of air into the lungs is as follows: the nasal cavity then pharynx then trachea then the bronchus then the bronchioles then to the alvioli and to the bloodstream.

From the capillaries of the alveoli, the blood travels through progressively larger veins of the pulmonary circulation, until it reaches the pulmonary vein and then the left atrium. From there, the oxygenated blood goes through the mitral valve into the left ventricle, then is pumped out the aorta. The oxygenated blood, with oxygen attached to the hemoglobin in the red blood cell, moves to body tissues through progressively smaller arteries of the systemic circulation. It moves out of the blood and into tissues via diffusion through the thin-walled capillaries, then into cells where it is used in cellular respiration.

How does oxygen travel through your body starting from the nasal cavity?

It goes to your lungs just like all other air.when air goes into any body part it always goes to your lungs.And oxygen isn't in the air,carbon dioxide is.

Briefly describe the path that oxygen follows in your respiratory system and your circulatory system?

Oxygen enters your respiratory system through the airways, passes through the lungs where it diffuses into the bloodstream in the alveoli. In the circulatory system, oxygen is carried by red blood cells through the pulmonary veins to the heart, then pumped to the rest of the body via the arteries. Oxygen is exchanged for carbon dioxide in the tissues, and then returned to the lungs to be exhaled.


What path does bacteria take when it enters the body?

When bacteria enters the body, it can enter through various routes, such as inhalation, ingestion, or through breaks in the skin. Once inside, bacteria can travel through the bloodstream or lymphatic system to different parts of the body where they can cause infection. The body's immune system response typically involves white blood cells trying to eliminate the bacteria.


What is the complete path of blood in the whole body in systemic circulation?

Oxygen-poor blood enters the right atrium of the heart from the body via the superior and inferior vena cava. It then flows into the right ventricle and is pumped to the lungs for oxygenation through the pulmonary arteries. Once oxygenated, the blood returns to the heart via the pulmonary veins, entering the left atrium, flowing into the left ventricle, and finally being pumped out to the rest of the body through the aorta.


What is the circulatory path of a red blood cell in the human body?

The pathway of blood is as follows: 1. Vena Cava (Superior/Inferior) 2. Right Atrium 3. Tricuspid Valve 4 Right Ventrical 5. Pulmonary Valve 6. Pulmonary Trunk 7. Pulmonary Arteries 8. Right/Left Lung 9. Pulmonary Veins 10. Left Atrium 11. Mitral/Bicuspid Valve 12. Left Ventrical 13. Aortic Valve 14. Aorta 15. Arteries 16. Arterioles 17. Capillaries 18. Venules 19. Veins Step one starts over again.

What is the path of air from outside of the body to the location where oxygen and carbon dioxide are exchanged?

Air enters the body through the nose or mouth, travels down the trachea into the bronchial tubes, and finally reaches the alveoli in the lungs where gas exchange occurs. Oxygen is absorbed into the bloodstream from the alveoli, and carbon dioxide is released from the bloodstream into the alveoli to be exhaled.


Describe the path that a molecule of oxygen takes as it moves form the air outside your body into the alveolar?

A molecule of oxygen enters the body through the nose or mouth, travels down the trachea, passes through the bronchi and bronchioles, and finally reaches the alveoli in the lungs where oxygen diffuses into the bloodstream through the thin walls of the alveoli.


What path does oxygen take as it enters the body?

Oxygen enters the body through the mouth or nose and travels down the trachea into the bronchial tubes, which then lead to the lungs. In the lungs, oxygen diffuses across the alveoli walls into the bloodstream where it binds to hemoglobin in red blood cells. The oxygen-rich blood is then pumped by the heart to the rest of the body's tissues and organs.


What path does oxygen take to enter the body in order?

Oxygen enters the body through the respiratory system. It is inhaled through the nose or mouth, travels down the trachea, enters the lungs, and then diffuses into the bloodstream through tiny blood vessels called capillaries in the lungs.


How will you describe the path way of oxygen and the breathing system?

Oxygen enters the body through the nose or mouth, then travels down the trachea into the lungs via the bronchial tubes. In the lungs, oxygen is exchanged with carbon dioxide in the alveoli, where it is absorbed into the bloodstream. The oxygen-rich blood is then pumped by the heart to the rest of the body's cells and tissues for energy production.

What path does oxygen take throughout the body?

Oxygen enters the body through the respiratory system by inhaling air through the nose or mouth. It travels through the trachea, bronchi, and bronchioles to reach the alveoli in the lungs. From the alveoli, oxygen diffuses into the bloodstream and binds to hemoglobin in red blood cells. The oxygenated blood is then pumped by the heart to various tissues and organs in the body where it is used for cellular respiration.


What sequence correctly shows the path of carbon dioxide during respiration?

External respiration is the exchange of oxygen and carbon dioxide between the lungs, body and the outside environment; the breathing process known as inhalation and exhalation. Upon inhalation, air enters the body and is warmed, moistened, and filtered as it passes to the alveoli of the lungs. Oxygen diffuses from the alveoli to the bloodstream, then into the red blood cells. Simultaneously, carbon dioxide in the blood is diffused from the blood to the alveoli, and exhalation expels the carbon dioxide from the alveoli.

What is the path of air as it travels the body?

Air enters the body through the mouth or nose, travels down the trachea, passes through the bronchial tubes in the lungs, and finally reaches the alveoli where oxygen is absorbed into the bloodstream and carbon dioxide is released. This process allows for gas exchange to occur in the lungs.


What is the path that a molocule of oxygen takes?

A molecule of oxygen enters the body through the respiratory system, where it is inhaled into the lungs. It then diffuses across the walls of the lungs into the bloodstream, where it is carried by red blood cells to tissues and cells throughout the body for cellular respiration. After being used by cells for energy production, carbon dioxide is produced as a waste product and transported back to the lungs to be exhaled.
