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.

In respiration ventilation, the diaphragm and intercostal muscles contract to increase the volume of the thoracic cavity, lowering the air pressure within the lungs. This pressure gradient causes air to flow into the lungs, allowing for the exchange of oxygen and carbon dioxide in the alveoli.

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.
How is ventilation controlled in response to changing demands on the body?
Ventilation is controlled by the respiratory centers in the brainstem, which monitor factors like blood pH, carbon dioxide levels, and oxygen levels to regulate breathing rate and depth. When demands on the body change, such as during exercise or when oxygen levels decrease, the respiratory centers adjust ventilation to meet the body's needs.
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 are the cellular respiratory processes that lungs perform?
The lungs perform the following cellular respiratory processes - pulminory ventilation external respiration internal respiration
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.
Where respiration occurs?
Respiration occurs in the cells.
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 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 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.
How does gasous exchange occurs?
Gas exchange occurs when oxygen from the air diffuses into alveoli in the lungs and then into the bloodstream, while carbon dioxide simultaneously diffuses from the bloodstream into the alveoli to be exhaled. This process allows the body to obtain oxygen for cellular respiration and remove carbon dioxide waste.
What is the difference between external ventilation and internal ventilation?
External respiration, the process by which gases are exchanged between the atmosphere and the pulmonary loop of circulationWhereas,Internal respiration: the is the gaseous exchange between the blood and tissue ( and also cells)
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.
