In the alveoli of the lungs. This is where oxygen diffuses from the lungs into the bloodstream and carbon dioxide diffuses out of the bloodstream and into the lungs.
The capillaries are the primary sites of exchange between blood and tissues. Capillaries are small blood vessels with thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. These exchanges are essential for maintaining the proper function of tissues in the body.
Nutrient exchange takes place in small blood vessels called capillaries, which have thin walls that allow for the exchange of gases, nutrients, and waste products between the blood and surrounding tissues.
Oxygen exchange takes place in the capillaries, which are the smallest blood vessels in the body.
Gas exchange between oxygen and carbon dioxide takes place in small sacs called alveoli, which are located at the end of the respiratory bronchioles in the lungs. This is where oxygen from the air is transferred into the bloodstream and carbon dioxide is removed from the blood.
Capillaries are the tiny blood vessels where exchange of nutrients, gases, and waste products occurs between the blood and body tissues through the process of diffusion. They have thin walls that allow for efficient exchange of substances.

In the capillaries, oxygen diffuses from the blood into the tissue cells, where it is used for cellular respiration. At the same time, waste products and carbon dioxide produced by the cells diffuse from the tissues into the blood to be transported to the lungs for exhalation. This exchange occurs due to differences in concentration gradients between the blood and the surrounding tissues.

Blood qualifies as a fluid tissue that moves from place to place in the body.

Alveoli.
The only place where gas exchange occurs between the atmosphere and the blood is in the alveoli of the lungs. These tiny air sacs facilitate the exchange of oxygen and carbon dioxide through their thin walls, allowing oxygen to enter the bloodstream while carbon dioxide is expelled from the blood to be exhaled. This process is essential for respiration and maintaining the body's oxygen levels.
Oxygen exchange takes place in the capillaries, which are the smallest blood vessels in the body.
Tiny air sacs where the exchange of gases between air and blood takes place are located in the lungs. These air sacs are called alveoli and are surrounded by capillaries where oxygen from the air enters the blood and carbon dioxide exits the blood into the air.
Simple squamous epithelium is the type of epithelial tissue present in the organs where exchange of substances takes place, such as in the lungs for gas exchange or in the kidney for filtration. This type of tissue is thin and allows for efficient diffusion of substances.
