Exchange of carbon-di-oxide for oxygen takes place between capillaries and tissues.
The exchange of gases occur through diffusion.
In Lungs, oxygen from inhaled air in the alveolar space moves into the RBCs in the capillaries and the carbon-di-oxide moves form the RBCs in the capillaries to the alveolar space which is exhaled during respiration.
In other tissues, the Oxygen is given to the tissues and carbon-di-oxide is taken from the tissues into the blood.
Many gases can be exchanged across the capillaries but the exchange of oxygen and carbon-di-oxide occurs normally in the body.
Gas exchange occurs in the alveoli of the lungs. These tiny air sacs are surrounded by capillaries where oxygen from the air can enter the bloodstream and carbon dioxide can be removed from the blood.

capillaries and tissue cells
alveolus
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
To allow Oxygen to travel to every Cell in a living organism there is a gas exchange between nearby Capillaries and the cells of that organism.The same exchange works the other direction to take away waste products of cell living
Capillaries. Its one-celled thick structure help it to perform its work efficiently
Exchange among subdivisions of the extracellular fluid (ECF) occurs primarily at the capillaries, where nutrients, gases, and waste products are exchanged between the blood and interstitial fluid. This exchange is facilitated by the thin walls of capillaries and the pressure differences between the blood and surrounding tissues.
yes capillaries are connected to heart because heart is a muscular organ and the exchange of materials between heart walls and blood occurs through capillaries.
