Respiration is the process of gaseous exchange by: External breathing, the oxygen is taken up by the capillaries of the lung alveoli
(air sacs) and expelled as carbon dioxide which is released from the blood. Internal, the stage of respiration in which oxygen is released to the tissues and carbon dioxide absorbed by the blood.

as leaves.
Gaseous exchange in humans takes place in the alveoli of the lungs. Oxygen from inhaled air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide from the blood diffuses into the alveoli to be exhaled.
Gaseous exchange is the movement of oxygen in the body, it takes place in the lungs through diffusion by the alveolar surface. There are millions of alveloi in the lungs, which gives it around 70m2 of exchange surface.
The term gaseous exchange is the movement of oxygen into the body. Your body needs a constant supply of oxygen for cellular resporation.
generally in the lungs and the alveli
Oxygen exchange takes place in the capillaries, which are the smallest blood vessels in the body.
Gaseous exchange occurs through capillaries all over the body to bring oxygen to cells and remove carbon dioxide.
As with most organs in the human body, gaseous exchange in the heart takes place via the capillaries, tiny blood vessels that release oxygen from the lungs into body tissue and receive carbon dioxide to transport back to the lungs.
through respiration
During respiration the exchange of gases takes place through the walls of the alveoli. From there, the oxygen is taken by the blood to the body tissues.
The exchange of nutrients and oxygen does not take place in the heart. The exchange of oxygen takes place in the alveoli of the lungs and the exchange of nutrients takes place at numerous sites around the body, but the most predominant is the duodenum and ileum of the small intestine.
artria
The blood cells carry carbon dioxide to the lungs which, through the mechanism of breathing, gaseous exchange takes place with the carbon dioxide leaving the body while someone breathes out. When they breathe in again, the blood cells in the pulmonary capillaries get loaded with oxygen and the new oxygen rich blood goes to the heart to be sent around the body.
