The oxygenated blood first enters the left atrium
The left ventricle pumps blood out of the heart and it leaves via the aorta.
the heart to get oxygenated
Veins are blood vessels that carry blood back from the cells to the heart. The pressure is rather low and the blood is moving slower than when the blood first leaves the heart.
after pupil first light enters aqueous humour or pupil
the first leaves are the primary leaves whereas the second leaves are the secondary leaves.
First, the deoxygenated blood enters the right atrium, then goes through the right ventricle. From there, it goes to the lungs, to become oxygenated. The oxygenated blood then goes through the left atrium and ventricle, before being pumped through the aorta to the rest of the body.
It enters the arteries.
blood, at first it is deoxygenated but by the time it leaves the lungs it is full of dissolved oxygen
The oxygenated blood first enters the capillaries, then they carry the blood through other veins to the rest of the body.
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.
Blood returning from the body systemic circulation first enters which chamber of the heart?
Deoxygenated blood first enters the heart through the right atrium.
it first passes through the duodenum
blood first enters the heart through the right atrium.
Through the vena cava. Blood enters the heart at the right atrium when from the systemic circulation. It Gets here through the superior and inferior vena cava and the coronary sinus. From the pulmonary circulation it enters the left atrium from the pulmonary vein.
it first enters the blood stream at the left brachiocephalic vein (at junction of the left subclavian vein and the left internal jugular vein)
The right atrium is where deoxygenated blood enters the heart.
