What is the largest type of artery?

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 are the 4 major arteries?

The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries.

What is the correct order of blood flow?

Blood enters the heart through two large veins – the posterior (inferior) and the anterior (superior) vena cava – carrying deoxygenated blood from the body into the right atrium. Blood flows from the right atrium into the right ventricle through the tricuspid valve.

What are the 5 Major blood vessels?

There are five classes of blood vessels: arteries and arterioles (the arterial system), veins and venules (the venous system), and capillaries (the smallest bloods vessels, linking arterioles and venules through networks within organs and tissues) (Fig 1).

Which blood vessel is the smallest?

Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries. Capillaries are so small they can only be seen under a microscope.

Which leg has the main artery?

The main artery of the lower limb is the femoral artery. It is a continuation of the external iliac artery (terminal branch of the abdominal aorta). The external iliac becomes the femoral artery when it crosses under the inguinal ligament and enters the femoral triangle.

What are the 3 types of arteries?

There are three main types of arteries:

• Elastic arteries.
• Muscular arteries.
• Arterioles.

What are the 3 layers of arteries?

The artery wall is comprised of three distinct layers: the intima, media, and adventitia. The intima is the innermost of three concentric layers, and is mainly connective tissue composed of a continuous ECs monolayer directly attached to the basement membrane which consists of collagen type IV and elastin.

What are your major arteries?

The aorta is the largest artery in the body that exits the left ventricle of the heart. Main branches from the aorta include the brachiocephalic artery, left carotid artery, and the left subclavian artery.

What are the 3 major veins?

These include the great cardiac vein, the middle cardiac vein, the small cardiac vein, the smallest cardiac veins, and the anterior cardiac veins. Coronary veins carry blood with a poor level of oxygen, from the myocardium to the right atrium.

What is the longest vein in the body?

Did you know that your Great Saphenous Vein is the longest vein in the human body? Extending from the top of your foot to the upper thigh and groin, THIS vein is the major culprit that causes Varicose Veins.

What is the pathway of blood?

Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs and body.

What is the correct order of blood flow through the kidneys?

Oxygenated blood comes to the kidneys from the right and left renal arteries off the abdominal aorta. Deoxygenated blood leaves the kidneys via the right and left renal veins that run into to the inferior vena cava.
