Red blood cells contain a chemical called hemoglobin which has the capacity to form a weak bond to oxygen molecules, so that the oxygen will be carried along, through the blood, by the hemoglobin, but will still be released by the hemoglobin later on, and will therefore be able to reach the various cells of the body, all of which need oxygen in order to metabolize food and generate chemical energy with which to function.
Oxygen moves from the lungs into the blood stream through the blood capillaries. It is usually transported through the alveoli sacs which are surrounded by many blood vessels.
Oxygen is brought into the blood stream by inhalation. Carbon dioxide moves out of the cells, into the blood, and taken to the lungs to be exhaled. Oxygen in, carbon dioxide out.
The questions leads towards which physiological important gases the blood contains.When the blood moves TO the lungs it has both CO2 (carbondioxide) and O2 (oxygen). However the level of oxygen is lower, and the level of CO2 is higher than with blood coming from the lungs.
the oxygen releases carbon dioxide
the oxygen releases carbon dioxide
In the lungs. The blood is pumped from the right side of the heart to the lungs. Air moves into the trachea, the bronchi and finally to the alveoli. From the alveoli oxygen diffuses into the microcapilaries (small blood vessels) of the lungs.
The left atrium receives blood from the lungs. This blood moves into the left ventricle to be sent out to the body.
through respiratory membrane via diffusion
Oxygen is moving by simple diffusion. It is going from a higher level of oxygen (air) to lower (blood).
we breath in mostly oxygen when we breath and when that oxygen goes to our lungs it goes through the bronchi and into little air sacs called alveoli the oxygen then moves into the blood going into the red blood cells while at the same time carbon dioxide moves out of the blood and comes out of body as exhales air
deoxygenated blood
moves out oxygen and removing in carbon dixode oxygen is necessary for life.without it no one can imagine of life. we get oxygen from atmosphere into the lungs from where it reaches to the every cell of the body. oxygeneted blood is purify blood, whereas deoxygeneted blood is impure blood. carbondioxide is necessary for plants etc. when we take breath the oxygen come in from the atmosphere to lungs and carbondioxide go out from the lungs into the atmosphere.
The respiratory system draws oxygen into the lungs. The circulatory system moves blood into the lungs to pick up the oxygen and then brings the oxygen to cells in the rest of the body.
