The two largest veins in the body are the superior vena cava, which carries blood from the upper body directly to the right atrium of the heart, and the inferior vena cava, which carries blood from the lower body directly to the right atrium.
What is the largest blood vessel in the body?
As the heart pumps inside the center of the chest, oxygenated blood circulates to organs and other tissues starting with the aorta, the largest artery in the body, and arteries that branch from it.
What is the order of blood vessels from largest to smallest?
Blood vessels include arteries, veins, and capillaries.
- Arteries are muscular blood vessels that carry blood away from the heart. …
- Veins are blood vessels that carry blood toward the heart. …
- Capillaries are the smallest type of blood vessels.

What are the two main types of blood vessels?
Are there different types of blood vessels?
- Arteries. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
- Capillaries. These are small, thin blood vessels that connect the arteries and the veins.
- Veins.
What are the 2 large veins that deliver blood into the right atrium?
The blood vessels include the superior and inferior vena cava. These bring blood from the body to the right atrium.
Which of the blood vessels is the strongest?
Blood vessels carry blood around the body. The 3 main types of blood vessels are: arteries that carry blood pumped from the heart — these are the largest and strongest.
What are the 4 major blood vessels?
The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart), and the coronary …
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).
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 is the smallest blood vessels in the body?
Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries. Capillaries are so small they can only be seen under a microscope. The walls of the capillaries are permeable to oxygen and carbon dioxide. Oxygen moves from the capillary toward the cells of the tissues and organs.
What are the 3 major blood vessels?
There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart. They’re tough on the outside but they contain a smooth interior layer of epithelial cells that allows blood to flow easily.
What are the major blood vessels?
There are three main types of blood vessels:
- Arteries. They carry oxygen-rich blood away from the heart to all of the body’s tissues. …
- Capillaries. These small blood vessels connect the arteries and the veins. …
- Veins. These are blood vessels that take blood back to the heart.
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.
Do all arteries carry oxygen-rich blood?
Arteries usually carry oxygenated blood and veins usually carry deoxygenated blood. This is true most of the time. However, the pulmonary arteries and veins are an exception to this rule. Pulmonary veins carry oxygenated blood towards the heart and the pulmonary arteries carry deoxygenated blood away from the heart.
Which side of human heart is low in oxygen?
The blood entering the right side of your heart is low in oxygen. This is because oxygen is removed from your blood as it circulates through your body’s organs and tissues. Your heart then pumps the blood to your lungs so it can receive more oxygen.
When blood flows through the aorta where is it going next?
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.
