From where does the blood get oxygen?
The blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
Which gas present in air takes part in a combustion reaction?
Oxygen.
What organ or structure absorbes oxygen from the air?
The respiratory system seems like the obvious answer, but you used the word absorb. The respiratory system takes air into the lungs, but the red blood cells (erythrocytes) absorb the oxygen out of the air taken into the lungs. The circulatory system then delivers these red blood cells to the capillaries where the oxygen is traded for carbon dioxide as the cells need.
What is the oxygen content of air?
The oxygen content of air is approximately 21%. Nitrogen is the largest component of air as it takes up 78% of the atmosphere.
Does oxygen go in body?
Generally, the air contains about 21% oxygen, 78% nitrogen and 1% a mixture of several gas. When we take a breath, the air go into the lung, down the trachea, then go into smaller broncial tubules, finally, the air go into a microscopic air sac called an alveolus. It is here that the exchange of oxygen and CO2 between the air and the blood takes place. Blood enters the lungs via the pulomanory arteries. It then proceeds through arterioles and into the alveolar capillaries. Oxygen and carbon dioxide are exchanged. The red blood cell is the main carrier of oxygen in the artery. The blood flow to the organs or tissues, in similar manner, oxygen and CO2 exchange in the capillary beds, and the blood carries CO2 back to lung. And a new cycle begins.
What saclike organ takes oxygen from the air and delivers it to the blood on an amphibian?
Lungs
Which organ system takes oxygen out of the air?
In air breathing animals, the lings are the organ system that takes in air and extracts oxygen for distribution through the circulatory system. In water breathing animals, the gills perform this function. Those smaller animals that have neither lungs nor gills usually have a system for direct absorption of oxygen from the air, or water.

Why you inhale oxygen only?
when you inhale air into your lungs the concentration of oxygen in the blood can be no greater than that in the air.As the blood reaching the lungs is lower in oxygen there is transfer from the air to the blood stream until the concentrations stabilise.However there is no active transfer.Therefore there will always be Oxygen in exhaled air even if the initial oxygen concentration in the blood is zero as the air oxygen and the blood oxygen will reach a steady state equilibrium

Which organ takes in oxygen?
The lungs absorbs oxygen into the blood
What do your lung take out of your blood?
The lung takes carbon dioxide out of your blood and replaces it with oxygen.
Why do the air you breathe out contain no oxygen?
The oxygen in the air you breathe in is absorbed via the lungs into the blood.
Which part of the human body takes in oxygen directly from the air?
The lungs take in oxygen directly from the air.
What has more oxygen air sacs or blood?
air sacs
Where the blood takes oxygen and nutrients?
To the rest of the body
