Carbon dioxide, when combined in liquid is mildly acidic. When you exhale, you're outgassing CO2. This would result in a small pH change making your blood less acidic as CO2 is released and O2 taken up.
The blood leaving the lungs is loaded with oxygen, while blood entering the lungs is about to get oxygen from the respiratory system.
carbon dioxide
Blood coming from the lungs has lower pressure while that from the heart has higher pressure. Blood coming from the lungs also has higher oxygen content and lower carbon dioxide content compared to that coming from the heart.
Blood leaving the lungs is oxygenated
The blood entering from the lungs has a high oxygen content and the blood entering from the body is high in carbon dioxide.
Blood entering the left atrium is oxygenated blood coming from the lungs that is pumped throughout the rest of the body.
Carbon dioxide leaves the blood and travels through the lungs before leaving your body.
Blood entering the heart from Superior vena cava and Inferior vena cava is "dirty". Bloold going through Pulmonary artery is 'dirty" and is "cleaned" (oxygenated) in the lungs. Blood entering the heart via pulmonary vein and leaving via aorta is clean.
Yes
Blood entering the right atrium is deoxygenated and saturated with CO2. Blood that is entering the left atrium has passed through the lungs and is oxygenated. It returns to the left atrium via the pulmonary vein and is saturated with oxygen. - Med Student
The blood absorbs oxygen from the lungs - enabling it to be transported throughout the body.
it goes through and around your body!
