Yes, the blood from the lungs is rich in oxygen. Since you breathe in oxygen and nutrients through your nose/mouth to the lungs, the oxygen and nutrients are absorbed in the lungs and go through the blood stream into the heart
The superior and inferior VENA CAVA are responsible for returning deoxygenated blood to the Heart.
I would say 'Oxygenated'.
Oxygenated blood
A blood vessel
Because they are also carrying oxygenpoor blood.
Yes, blood flows into the heart via veins. Blood flows away from the heart in aryteries.
The blood returns to the heart through veins.
Inferior vena cavae
No. Blood from the head returns to the right side of the heart and is then pumped ino the lungs. The blood from the head returns to the heart and is then sent to the lungs. If it went to the lungs before returning to the heart, that would be wasteful becase then it would have gone through the lungs twice before going to where it was needed.
Veins are the type of blood vessel that drains blood from tissues and returns it to the heart.
Blood is bright red when it returns to the heart from the lungs. It is darker red when it returns to the right atrium from the systemic circulation.
Because they are also carrying oxygenpoor blood.
The blood vessels that carry the blood from the heart to the lungs are the pulmonary arteries. Blood returns from the body and is pumped by the right ventricle to the lungs, through the pulmonary arteries. The blood returns to the left side of the heart through the pulmonary veins.
the blood returns because of the preasure with in the body it cotracts to pump the blood and relaxes that's when the blood returns on the other side
Blood returns to the heart via the pulmonary veins and it enters into the left atra.
Pulmonary vein
The atria are chambers that receive blood that returns to the heart.
The atria are chambers that receive blood that returns to the heart.
deoxygenated blood
Yes, blood flows into the heart via veins. Blood flows away from the heart in aryteries.
the same thing all veins do, it returns blood to the heart and circulation , arteries take blood to the body
