it goes to the lungs
The blood passes through tiny capillaries that lie in close proximity to the alveoli in the lungs. This is where the gas exchange takes place.
carbon dioxide
Mostly arteries.
blood take oxygen from blood.
bye- bye!!
In the alveoli of the lungs, where it passes into the blood capillaries which surround them.
The body has a double circulation the blood passes through the heart twice in one complete circuit.
The heart, lungs, kidneys, and liver are the four major organs through which the blood passes in the body. The heart pumps oxygen-rich blood to the lungs for oxygenation, then to the kidneys and liver for filtering and detoxification before circulating back to the heart.
There are two types of circulations, known as lesser and greater circulation. They are placed in series. say blood enters in right atrium through superior and inferior vena cave. Then it enters right ventricle. Then it passes to lungs, via pulmonary trunk. After purification from here it goes to left atrium. From it goes to left venrticle. From left ventricle it goes to all the body, but lungs. then from superior and inferior vena cave it again enters the left atrium.
From the main vein the blood enters the right artery which will then pump into the right artery next right vertical will pump the net into the lungs. After passing through the lungs they will enter the left artery the veins the left artery pump the blood into the left
