Through breathing.
The lungs.
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
Oxygen is brought into the blood, and carbon dioxide released from the blood, at the alveoli of the lungs. Gases diffuse across the alveolar membrane to enter or leave the blood.

It is carbon dioxide which is collected from different organs of the body by blood
The place is the same for both; the alveoli in the lungs.
Oxygen enters the blood through the alveoli in the lungs during inhalation, where it diffuses into the bloodstream. Carbon dioxide leaves the blood in the same location, diffusing from the blood into the alveoli to be exhaled during exhalation.
Diffusion
Blood picks up oxygen and releases carbon dioxide in the lungs.
Blood picks up oxygen and releases carbon dioxide in the lungs.
Blood carbon dioxide levels help regulate the pH of the blood. Carbon dioxide is converted to bicarbonate ions in the blood, which helps maintain the blood's acid-base balance. Changes in blood carbon dioxide levels can result in respiratory and metabolic imbalances.
Venous blood is loaded with carbon dioxide and low in oxygen Arterial blood is rich in oxygen with little carbon dioxide
