Yes, some CO2 is returned to the lungs by hemoglobin transport.
Oxygen is carried by hemoglobin in red blood cells, forming oxyhemoglobin. Carbon dioxide is carried in the blood mainly in the form of bicarbonate ions, but also as carbaminohemoglobin and dissolved CO2. These gases are exchanged between the blood and tissues in the lungs and other tissues in the body.
Carbon dioxide is a waste product of cells produced during cellular respiration as cells break down nutrients to create energy. It is then transported in the blood to the lungs where it is exhaled from the body.
The primary function of white blood cells is to fight infection. Red blood cells carry oxygen from the lungs to the body tissues, and carbon dioxide as a waste product away from the tissues and back to the lungs.
The respiratory system is primarily responsible for providing cells with oxygen and removing carbon dioxide. Oxygen is taken in through the lungs and transported by red blood cells to cells throughout the body, while carbon dioxide is released from cells, carried back to the lungs, and exhaled.
Oxygen enters cells through diffusion, where it moves from areas of high concentration in the bloodstream to low concentration in cells. Carbon dioxide exits cells through the same process, diffusing from high concentration in cells to low concentration in the bloodstream for removal by the lungs.
Venous blood is loaded with carbon dioxide and low in oxygen Arterial blood is rich in oxygen with little carbon dioxide
Respiration is the process that carries oxygen to the cells and removes carbon dioxide from them. Blood carries the oxygen to the cells.

Oxygen is carried in the blood by attaching to hemoglobin molecules in red blood cells. When the blood reaches cells that need oxygen, it is released from hemoglobin and diffuses into the cells. Carbon dioxide is mainly transported in the blood as bicarbonate ions, which are formed when carbon dioxide reacts with water in red blood cells.
Oxygen is inhaled into the lungs, where it is transferred to the blood and carried by red blood cells to tissues. Carbon dioxide is produced by cells as a waste product and transported back to the lungs through the blood to be exhaled. This flow of oxygen and carbon dioxide ensures that cells receive the oxygen they need for energy production and get rid of carbon dioxide.
Carbon dioxide rich blood, which is red blood cells lacking oxygen but high in carbon dioxide concentration.These blood cells have circulated through the body and given up much of its oxygen while collecting waste carbon dioxide. The pulmonary artery carries this blood from the heart to the lungs, where it picks up a fresh supply of oxygen and eliminates carbon dioxide.
In arterial blood cells Oxygen. In venous blood cells Carbon Dioxide.
