Once inhaled air enters the lungs, oxygen is absorbed through the alveoli in the lungs and enters the blood stream. The oxygenated blood travels through the pulmonary vein to enter the left atrium -> left ventricle of the heart, which is the pumping chamber.
The heart then pumps this oxygenated blood via aorta (the majory artery) to all the different muscles and organs in the body. As the oxygenated blood approaches its target destination, oxygen diffuses out of the artery, through the capillaries, and into the oxygen deficient area. The muscle/ organ/ whatever now has oxygen to utilize!
At the same time, HCO3-, a molecule that essentially exists for carbon dioxide to be liquid soluble, diffuses through the capillary into the vein. The deoxygenated blood is then forced back into the right atrium-> right ventricle-> pulmonary artery back into the lungs to be oxygenated once more.
The path is simple, but understand that the process of diffusion is a matter of both chemical equilibria (remember, movement is high solute-> low solute) and osmotic balance.
What else can I help you with?
What best describes where cellular respiration?
Aerobic respiration occurs in the mitochondria of body cells. Anaerobic respiration (glcolysis) occurs in the intracellular cytosol.
What occurs during the first stage of respiration?
Glycolysis occurs in the cytoplasm during the first stage of respiration.
The part in which respiration occurs is?
Respiration occurs in the mitochondria of cells, specifically in the inner membrane where the electron transport chain and ATP synthesis take place. This is the final stage of cellular respiration, following glycolysis and the citric acid cycle.
What is the only stage of cellular respiration that occurs in the cytoplasm?
Glycolysis, the first stage of respiration, occurs in the cytoplasm.A molecule of glucose splits into two molecules of pyruvate. No oxygen is needed for this stage of respiration and it occurs in cells that respire using mitochondria and cells that ferment sugars.
How is ventilation controlled in response to changing demands on the body?
Ventilation is a process humans rely on to maintain high oxygen and low carbon dioxide concentrations at the gas exchange surface. The process that ventilates lungs is breathing. Humans ventilate the lung by negative pressure breathing
Where respiration occurs?
Respiration occurs in the cells.
Air moving in and out of lungs is called?
Breathing is the simple answer. Respiration is also an answer but respiration includes oxygen going into the bloff and throughout the body and Carbon Dioxide going back to the lungs and being exhaled.
What is the organelle where respiration occurs?
Cellular respiration occurs in the mitochondria.
The act of ventilation occurs in the?
trachea
What controls respiration under normal conditions?
pulmonary ventilation
What is the difference between breathing respiration and ventilation?
respiration is the process of yainhaling oxygen to the body and provide the cells.
What are synonyms of respiration?
Breathe, airing, panting, oxygenating, ventilation, and inhalation are synonyms for respiration. Cellular respiration is when a cell exchanges O2 and CO2.
What is ventilation?
first of all, its ventilation and it means breathing. but don't get mixed up with respiration and breathing they are different!
What best describes where cellular respiration?
Aerobic respiration occurs in the mitochondria of body cells. Anaerobic respiration (glcolysis) occurs in the intracellular cytosol.
What occurs during the first stage of respiration?
Glycolysis occurs in the cytoplasm during the first stage of respiration.
Where does respiration occur at in the cell?
Cellular respiration occurs in the mitochondria.
What Respiration that occurs when a lot of oxygen is present?
Aerobic respiration
