aorta
The circulatory system is a closed loop system. It starts and ends at the heart. The blood doesn't leave the system and is pumped back to the heart to start the journey of the cycle again. The circulatory system runs throughout the body to supply blood to all parts.
They both work to provide oxygen to the cells. The respiratory system provides air to the circulatory system. The the blood from the circulatory system delivers oxygen to the cells. For more help search on the Internet. :)
The process by which red blood cells are produced is called erythropoiesis. It occurs in the bone marrow and is regulated by the hormone erythropoietin, which stimulates the production of red blood cells from stem cells. Erythropoiesis is essential for maintaining a stable supply of red blood cells in the body to carry oxygen to tissues.
In fetal circulation, the placenta provides oxygen and nutrients to the fetus, so the lungs are not used for oxygen exchange - instead, a bypass called the ductus arteriosus shunts blood away from the lungs. After birth, the lungs take over oxygen exchange, the ductus arteriosus closes, and the foramen ovale between the atria closes, redirecting blood flow through the heart to support pulmonary circulation.

pulmunary artery
The pulmonary artery contains deoxygenated blood. It is going to the lungs to pick up oxygen.
The pulmonary artery.
Vessels that carry blood away from the heart are arteries. The main artery from the heart that contains oxygen-rich blood is the aorta.
The pulmonary artery contains the least amount of oxygen, as it carries deoxygenated blood from the heart to the lungs to be oxygenated.
An artery contains blood pumped away from the heart. The pulmonary, or "lung" artery pumps "used" blood from the body away from the heart to the lungs to get a new, fresh load of oxygen for the body.
The main artery that serves as the passageway for blood as it leaves the heart is the aorta. The aorta is the largest artery in the body and carries oxygen-rich blood from the heart to the rest of the body.
The aorta is the largest artery in the human body.
The right atrium and ventricle of the heart, as well as veins, contain oxygen-poor blood. The left atrium and ventricle, as well as the arteries, contain oxygen-rich blood. One exception to this is the pulmonary vein and artery, which are reversed - pulmonary artery contains oxygen-poor blood and pulmonary vein contains oxygen-rich blood.
The aorta is the largest; it takes oxygenated (oxygen rich) blood from the heart to the body.
