by diffusion across a capillary wall
The circulatory system (blood and vessels) transports oxygen and nutrients around the body. The heart furnishes the power to move the blood.
During respiration, oxygen enters the body through the respiratory system (nose, trachea, lungs) and reaches the alveoli where it diffuses into the bloodstream. The oxygen is then transported by red blood cells to tissues and cells where it is used to produce energy through cellular respiration. Carbon dioxide, a waste product of this process, is carried back to the lungs to be exhaled.
Oxygen moves into the blood by diffusing across the respiratory membrane in the lungs. This process occurs in the alveoli, tiny air sacs where oxygen enters the bloodstream from the surrounding air. From there, oxygen binds to hemoglobin in red blood cells for transportation to tissues throughout the body.
Air or CO2 must pass through the respiratory system, specifically the lungs. During exhalation, these gases move out of the lungs and are expelled from the body through the nose or mouth.
Oxygen is used by the cells for aerobic respiration -- the oxidation of carbohydrates to provide energy for the cells. The process provides the energy to move muscles, and to build tissues, and to keep the body warm.
The respiratory system and the circulatory system work together to move oxygen throughout the body. The respiratory system takes in oxygen from the air and delivers it to the bloodstream, while the circulatory system transports oxygen-rich blood to all the cells in the body.
Material moves from the respiratory system to the circulatory system by diffusing across a membrane in the air sacks called alveoli.

The circulatory system helps move oxygen throughout your body.
Even if insects have an open circulatory system, which is usually characterized by slow animals with low metabolic rates, their circulatory system does not participate in supplication of oxygen to the tissues and in the gas exchange process. That is handled by the independent tracheal system, the spiracles, which allows direct contact of cells with the air. With this, the oxygen demand can be supplied even with an open circulatory system.source: http://www.biology-questions-and-answers.com/the-circulatory-system.html
The respiratory system feeds the cardiovascular system oxygen which the cardiovascular system then transports to every living cell in the body and simultaneously the cardiovascular system is transporting carbon dioxide to the respiratory system so that the respiratory system will expel the carbon dioxide from the body (large amounts of carbon dioxide are fatal). This balance is necessary of oxygen and carbon monoxide to cells (all of them) in producing energy that is used to move muscles and maintain the homeostatic temperature of the body.
The Respiratory system. We breathe oxygen containing air into our lungs. Our hearts send 'old' blood to the lungs where the carbon dioxide is removed and oxygen added, and that oxygen enriched blood is carried around the body until it lands up in the lungs again. So is it really a joint effort by the circulatory system and the respiratory system.
The Muscular System depends on then Nervous System because nerve signals from the brain to the correct muscle so it may be able to move. 1. it depends on the nervous system because of whats stated up there. ^^^^^ 2. it depends o the respiratory system because it needs oxygen to move around. 3. it depends on the Circulatory system because it needs to oxygen from somewhere. 4. and it depends on the digestive system because it needs glucose to function. 5. Brain to control the nervous system
Diffusion occurs in the respiratory system, where oxygen and carbon dioxide exchange happens in the lungs. It also occurs in the digestive system, where nutrients pass through the walls of the small intestine into the bloodstream. Additionally, diffusion takes place in the circulatory system, where gases and nutrients move between blood and tissues at the capillaries.
Material moves from the respiratory system to the circulatory system by diffusing across a membrane in the air sacks called alveoli.
The primary system to get rid of CO2 is the respiratory system. But it is aided by the circulatory system which delivers CO2 to the aveoli, where hemoglobin on Red blood cells then picks up O2 to take back to the cells.
