The only vein to carry oxygenated blood is the pulmonary vein which carries blood from the lungs to the right atrium.
Arteries always carry blood away from the heart.
Usually the blood is oxygenated; the exceptions are the pulmonary arteries, which carry blood away from the heart to the lungs to become oxygenated.
The 4 chambers of the heart are the left atrium and right atrium (upper chambers), and the left ventricle and right ventricle (lower chambers).
The right side of the heart collects blood on its return from the rest of the body.
The blood entering the right side of the heart is low in oxygen.
The largest structure of the heart is the left ventricle.
The left ventricle is the largest and strongest chamber in the heart.
The left ventricle's chamber walls are only about a half-inch thick, but they have enough force to push blood through the aortic valve and into the body.
The smallest blood vessels in the body are called the capillaries.
Capillaries are the smallest blood vessels that connect the arteries and veins together.
The main vein that carries oxygen rich blood is the aorta although more than one vein carries oxygen rich blood.
The pulmonary veins bring oxygen-rich blood to the left atrium.
The aorta carries oxygen-rich blood to the body from the left ventricle.
The main artery in the human body is called the Aorta.
The largest artery in the body is the Aorta artery.
The aorta is the main artery that carries blood away from your heart to the rest of your body.
The blood leaves the heart through the aortic valve.
Then it travels through the aorta, making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles and other cells.
The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle.
The aorta branches into a network of smaller arteries that extend throughout the body.
The arteries' smaller branches are called arterioles and capillaries.
The aorta is divided into four sections: The ascending aorta rises up from the heart and is about 2 inches long.
The coronary arteries branch off the ascending aorta to supply the heart with blood.
The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.
The aorta, normally on the left side of the body, may be found on the right in dextrocardia, in which the heart is found on the right, or situs inversus, in which the location of all organs are flipped.
Variations in the branching of individual arteries may also occur.
An aortic aneurysm develops from a weakness in the wall of the aorta.
This weakness can be present at birth or can develop as the result of disease or injury.
Atherosclerosis: A clogged or damaged artery from a condition called atherosclerosis is the most common cause of aneurysm.
