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.
The full anatomical pathway of oxygen from outside the body to the blood stream would be this:
- Air is inhaled through the external nares (nostrils) into the nasal cavity and the paranasal sinuses.
- From there, it passes through the three regions of the pharynx: the nasopharynx (uppermost), oropharynx (middle) and the larngopharynx (lowermost region).
- From the pharynx, it passes through the larynx (which contains the epiglottis which prevents food or water entering the trachea) to the trachea.
- The trachea leads to the the two primary bronchi which branch off into the secondary bronchi > tertiary bronchi > bronchioles > terminal bronchioles > respiratory bronchioles < the diameter of the "tube" getting smaller each time it branches.
- From the respiratory bronchioles to the alveolar ductsthen the alveoli themselves
- Gases exchanges occurs between the alveoli and the surrounding capillaries and it is here that oxygen enters the bloodstream
once you breath in the air it goes down to your heart and is infused with red blood cells that travel all around your body until they get to a muscle then the muscle uses the air as a sort of gas that's making the pistons of a car[your body] go back and forth back and forth that powers your "car".
Oxygen enters the body along with other components of the air, when you inhale. It enters the lungs, where blood vessels that travel through the lungs receive the oxygen, and is bonded with red blood cells which are adapted to collect oxygen atoms.
It then re-enters the heart where it can then travel to every cell in the body through the arteries, and is used in muscle tissue for energy. The process of burning oxygen needs another component: carbon, which we eat when we consume things like rice, pasta, potato, and bread, but its found and pretty much everything organic. The tissues in our body derive energy from this process. What results when you combine oxygen and carbon? Carbon dioxide. This is then carried back through the veins, in the form of Carbonic Acid (H2CO3), to the heart, then to the lungs, where we then breathe it out.
Through the capillaries
which part completes the path of blood in whole body(systemic)circulation
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. 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.
When tracing the path of oxygen, water, carbon dioxide and glucose in the production of energy it will show that first oxygen and water enter the cell. Carbon dioxide and glucose are then produced in the cell and carbon dioxide is given off. Energy is also dispelled as glucose.

Yes, and back again, having picked up oxygen and dumped CO2.
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.
After entering it takes the left pump after entering
Colloid silver first passes into the stomach, most of it will continue on that path out of the body. Some is absorbed into the blood stream though and able to pass with-out issue.
After entering it takes the left pump after entering
The heart pumps your blood (cardio), into your lungs (respitory), to give them oxygen. Then it makes itsway around the body to supply oxygen to where it is needed. Then then new blood, without oxygen, goes on the exact same path.
The kidneys filter all toxins and chemicals, called urea, out of the bloodstream, then they move down into the bladder where they mix with excess water and salts. From there they are expelled. Nephron, Collecting duct, Minor calyx, Major calyx, Pelvis, Ureters, Bladder, Urethra, Outside the body.
Orbit is the path
The path that food takes to get out of the small intestine and into the blood is through the body cells. When food is broken down in the stomach, nutrients are absorbed through the intestinal walls. The nutrients cross the mucosa into the bloodstream where they are transported to other parts of the body.
Plant releases oxygen. Oxygen molecules diffuse. Bear inhales.
