to the heart.
thru your nose in to your lungs and finaly to you blood
blood gets a fresh dose of oxygen from the lungs and a fresh ration of food from the liver
from the lungs where does it go back
The diaphragm squeezes the air out of your lungs
The lungs.
yes
The blood goes through the lungs because the blood has to get purified and then go to all parts of the body.
Fresh blood is brilliant red, but as it clots it will turn brown.

The alveoli, or air sacs, of the lungs. Blood is returned by veins to the vena cava, and to the right atrium of the heart. The blood is pumped by the heart's right ventricle to the lungs through the pulmonary arteries. The pulmonary veins return the oxygenated blood to the left atrium, where it is pumped by the left ventricle into the body's arteries through the expanded artery called the aorta.
what do you mean by "fresh blood"? Deoxygenated blood from the body comes through the inferior and superior vena cava. Oxygenated blood from the lungs comes to the heart through the pulmonary veins.
The circulatory system is where the heart exchanges de-oxygenated blood for oxygenated blood from the lungs to go through the veins and arteries. As for the respiratory system, this is involving the lungs in exchanging carbon dioxide for oxygen, through the process called breathing. The heart and lungs depend on each other. If the lungs does not give blood its needed oxygen, then all the organs would fail, causing a horrible death, and if the heart does not keep the lungs alive, with fresh blood (that the lung gave oxygen to) then the lungs would fail, causing the heart to go into a heart attack.
