pulmonary vein: One of four veins that carry oxygen-rich blood from the lungs to the heart.
Which veins deliver blood from the lungs?
- The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium.
- The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream.
- The pulmonary veins bring oxygen-rich blood to the left atrium.
Which blood vessels bring blood to and from the heart?
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart.
Which vessel carries blood from the lungs and returns it to the heart?

Which side of human heart is low in oxygen?
The right side of your heart collects blood on its return from the rest of our body. The blood entering the right side of your heart is low in oxygen. Your heart pumps the blood from the right side of your heart to your lungs so it can receive more oxygen.
Do lungs have veins?

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 are the different kinds of blood vessel?
There are three kinds of blood vessels: arteries, veins, and capillaries.
What carries blood from the body to the heart?
There are three main types of blood vessels
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.
What vein goes to the heart?
The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
What are some places that blood goes after leaving the heart?
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.
Which body part is designed to move the blood around your body?
The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body. It usually beats from 60 to 100 times per minute, but can go much faster when necessary.
Where is your heart located on a man?
