The aorta is the largest artery in the body. It carries oxygenated blood from the left ventricle of the heart into systemic circulation. The aorta has many subdivisions that branch off into smaller arteries.
Where do arteries carry blood?
The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
What is unique about blood in pulmonary arteries?
Structure. The pulmonary arteries are blood vessels that carry blood from the right side of the heart through to the capillaries of the lungs. The blood that is carried is, unlike other arteries, without oxygen (“deoxygenated”).
What is the largest artery found in the body?
Aorta Anatomy
The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
What are the two exceptions to arteries carrying oxygenated blood?
Most arteries carry oxygenated blood; the two exceptions are the pulmonary and the umbilical arteries, which carry deoxygenated blood to the organs that oxygenate it (lungs and placenta, respectively). The effective arterial blood volume is that extracellular fluid which fills the arterial system.

What do you call the smallest blood vessels in the body?
Veins carry blood back toward your heart. Capillaries, the smallest blood vessels, connect arteries and veins.
Which part of heart contains pure blood?
The left half of the heart collects and pumps pure (oxygenated) blood from the lungs to all parts of the body.
How can I remember the arteries of my brain?
Useful mnemonics to remember the branches of the internal carotid artery is: A VIP’S COMMA. Calming Voices Make Intra-Operative Surgery Pleasurable And Almost Memorable.
What’s the main artery called?
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.
What is the smallest artery in the body?
The smallest of the arteries eventually branch into arterioles. They, in turn, branch into a extremely large number of the smallest diameter vessels—the capillaries (with an estimated 10 billion in the average human body). Next blood exits the capillaries and begins its return to the heart via the venules.
What is the largest artery and vein in the body?
The largest artery in the body is the aorta, which is connected to the heart and extends down into the abdomen (Figure 7.4. 2). The aorta has high-pressure, oxygenated blood pumped directly into it from the left ventricle of the heart.
What are the 5 major arteries?
This is a list of arteries of the human body.
- The aorta.
- The arteries of the head and neck. The common carotid artery. The external carotid artery. …
- The arteries of the upper extremity. The subclavian artery. The axilla. …
- The arteries of the trunk. The descending aorta. …
- The arteries of the lower extremity. The femoral artery.
What artery is the widow maker?
The widow-maker is a massive heart attack that occurs when the left anterior descending artery (LAD) is totally or almost completely blocked. The critical blockage in the artery stops, usually a blood clot, stops all the blood flow to the left side of the heart, causing the heart to stop beating normally.
Which coronary artery is most commonly blocked?
The LAD artery is the most commonly occluded of the coronary arteries. It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system.
Which leg is your main artery in?
The femoral artery is the major blood vessel supplying blood to your legs. It’s in your upper thigh, right near your groin.
How many arteries supply the brain?
There are two paired arteries which are responsible for the blood supply to the brain; the vertebral arteries, and the internal carotid arteries.
What does circle of Willis mean?
The Circle of Willis is the joining area of several arteries at the bottom (inferior) side of the brain. At the Circle of Willis, the internal carotid arteries branch into smaller arteries that supply oxygenated blood to over 80% of the cerebrum.
Which organ is purify the blood?
Liver. your liver is the organ below the lungs. It acts like a filter for the blood. Chemicals and impurities, including from drugs and medications, are filtered by the liver.
Does heart filter blood?
How do the kidneys and heart work together? The heart pumps blood filled with oxygen through all parts of your body, including the kidneys. The kidneys clean the blood, removing waste products and extra water. Without the kidneys, your blood would have too much waste and water.
