Answer:
The Journey of a Breath of Air
Breathing is only part of the process of bringing oxygen to where it is needed in the body. After oxygen enters the lungs, what happens?
The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion.
The oxygen-rich blood returns to the heart.
Oxygen-rich blood is then pumped through the aorta, the large artery that receives blood directly from the heart.
From the aorta, oxygen-rich blood travels to the smaller arteries and, finally, to the capillaries, the smallest type of blood vessel.
The oxygen molecules move, by diffusion, out of the capillaries and into the body cells.
While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.
Carbon dioxide is brought, through the blood, back to the heart and then to the lungs. Then it is released into the air during exhalation.
Why is oxygen needed by each cell in your body? To make ATP, the usable form of cellular energy. Oxygen is needed in the final stage of cellular respiration, which is the process of converting glucose into ATP. This process is much more efficient in the presence of oxygen. Without oxygen, much less ATP is produced. As ATP is needed for the cells to function properly, every cell in your body needs oxygen. Getting that oxygen begins with inhaling. The oxygen moves into your blood, where it travels to every cell in your body.
Answer:
Breathing me in, I come in through the nose. Quickly, I go through th throat and into a tube. In one of the lungs I go through the bronchi. I get absorb by cell bodies with nutrients and turns into energy. I get used by a human body so they won’t die. The respiratory system makes the heart pump blood and oxygen and carbon dioxide exchange, and exhaled while getting rid of waste.
The steps of the air entering our lungs. First, the air enters our body through our nose or mouth. Next, the air passes through our throat, in our throat there are the pharynx and the larynx (voice box). Finally, air passes into the trachea (strong tube) witch divides into two branches (bronchi). Before the air enters your body it has to go through three steps.
The air is now in the lungs. First, the bronchi leads the air to a air sac called alveoli. Next, the alveoli is surrounded by tiny blood vessels called capillaries. Then, in the capillaries, oxygen in the air enters the blood, in the capillaries carbon dioxide leaves the blood then it enters alveoli. Finally, CO2 is exhaled.
Cellular respiration happens in animal cell in the whole body. First, in the capillaries blood cells absorbs oxygen from the air in the alveoli. Secondly, nutrients and oxygen exits out of the body cell and goes into other body cells. Third, carbon dioxide and HO2 exits from the body cells, then it goes back into the blood cells in the capillaries. To be oxygenated the capillaries takes carbon dioxide-rich cells back to the lungs. In the whole body is where cellular respiration happens.
The body needs oxygen to do things to make it survive. The body need oxygen and nutrients to make energy. Without oxygen the heart won’t pump blood. What else would happen if the heart won’t pump blood?
