Lungs~pulmonary veins~left atrium~left ventricle
It depends blood doesnt go into the lungs but if your talking about how does blood travel threw lungs its by veins.
To the lungs
Blood that has perfused the lungs and is now oxygenated collects into the pulmonary veins to travel back to the heart. Once reaching the heart, oxygenated blood from the lungs enters the left atrium. The left atrium collects blood from the lungs
The pulmonary veins carry blood from the lungs back to the heart.
Red blood cells are part of the blood and travel where the blood goes. Blood is moved through the heart to the lungs and back to the heart. Then it is moved through arteries to all the tissues of the body and back to the heart through the veins.
Veins allow blood to travel from the body and lungs back to the heart (to be pumped to the body and lungs, simutaneously and seperately).
The heart pumps blood to different parts of the body through small tubes called blood vessels. The human body has two circulatory systems. Pulmonary Circulation and Systemic Circulation. Pulmonary Circulation - blood flows from the heart to the lungs and then back from lungs to heart. Systemic Circulation - blood flows from the heart to other organs in the body and back from other organs to the heart.
The inferior vena cava brings blood back to the heart from the lungs.
from the lungs where does it go back
So as to get OXYGENATED by process of OXYGENATION(and not oxidation).
There are two circuits: Pulmonary-carries blood to the lungs and back to the heart Systemic-carries blood from the body and back to the heart
The pulmonary circulation carries blood from the heart to the lungs and back. In the pulmonary circulation, arteries carry deoxygenated blood.
