Lunges primarily work the muscles in the legs and buttocks, helping to build strength and endurance in those areas. The cardiovascular system is responsible for transporting oxygen to tissues, and activities like aerobic exercises, such as running or swimming, are more effective at improving oxygen delivery to tissues throughout the body.
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
The respiratory system is responsible for exchanging carbon dioxide from the bloodstream for oxygen to be delivered to tissues. This process occurs in the lungs where oxygen is inhaled and carbon dioxide is exhaled.

Red blood cells transport oxygen from the lungs to the tissues and remove carbon dioxide from the tissues back to the lungs for exhalation.
Red blood cells, also known as erythrocytes, are responsible for transporting oxygen from the lungs to the body tissues and carbon dioxide from the tissues to the lungs for elimination. These cells contain hemoglobin, a protein that binds to oxygen and carbon dioxide for transport.
No, humans do not breathe in carbon dioxide. We inhale air that contains oxygen and exhale carbon dioxide as a waste product of respiration. Breathing in too much carbon dioxide can be harmful to our health.
Red blood cells have the highest affinity for both oxygen and carbon dioxide. This is due to the presence of the protein hemoglobin in red blood cells, which binds to oxygen and carbon dioxide molecules. Hemoglobin helps transport oxygen from the lungs to tissues and carries carbon dioxide away from the tissues to be exhaled from the lungs.
Hemoglobin
Haemoglobin binds to oxygen in the lungs to transport it to tissues throughout the body. It also binds to carbon dioxide in the tissues and transports it back to the lungs for exhalation. This crucial function helps to maintain the body's oxygen and carbon dioxide balance.
