What part of the heart distributes blood to body organs except lungs?
The right ventricle pumps the blood from the right atrium into the lungs to pick up oxygen and remove carbon dioxide. The left atrium receives blood from the lungs. This blood is rich in oxygen. The left ventricle pumps the blood from the left atrium out to the body, supplying all organs with oxygen-rich blood.
What does the pulmonary trunk do?
The pulmonary trunk is a short artery transporting deoxygenated blood from the heart towards the lungs. Some authors refer to this vessel as the main pulmonary artery, or simply the pulmonary artery. The pulmonary trunk arises from the base of the right ventricle of the heart.
What gives rise to the left and right pulmonary arteries?
The sixth aortic arch gives rise to both the right and left pulmonary arteries and the ligamentum arteriosum. The ligamentum arteriosum is the ductus arteriosus during fetal development. The ductus arteriosus serves to allow oxygenated fetal blood to bypass the developing lungs and move directly into the aorta.
Which of these structures returns blood to the right atrium?
1. Superior vena cava: Receives blood from the upper body; delivers blood into the right atrium.
Which part of the heart distributes blood to the body?
From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
Which part of the heart pumps blood to the lungs?
right ventricle
The right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA). From there, the blood flows through the right and left pulmonary arteries into the lungs.
Is pulmonary trunk a vein?
The pulmonary trunk is a short and stout (wide) structure that is about 5 cm in length and 3 cm in diameter, which branches into 2 pulmonary arteries; the left and right pulmonary arteries, which act to deliver deoxygenated blood to its respective lung.
What is another name for pulmonary trunk?
The pulmonary trunk, also known as main pulmonary artery (mPA), (TA: truncus pulmonalis) is the solitary arterial output from the right ventricle, transporting deoxygenated blood to the lungs for oxygenation.
What is the largest artery in your body?
The aorta
The aorta is the largest blood vessel in your body. It’s more than 1 foot long and an inch in diameter at its widest point.
What is the difference between pulmonary artery and artery?
The main difference between pulmonary artery and other arteries is that pulmonary artery carries deoxygenated blood whereas the other arteries carry oxygenated blood. Furthermore, the pulmonary artery supplies blood to the lungs while the other arteries supply blood to the body.
Which 3 vessels carry blood to the right atrium?
Deoxygenated blood enters the right atrium through three major veins: the superior and inferior vena cava and the coronary sinus. The superior vena cava returns all of the blood to the heart from tissues superior to the heart in the head, neck, arms and upper thorax.
Which of the following structures does not return blood to the right atrium?
Answer and Explanation: The right atrium does not receive blood from the d) circumflex artery.
What are the 4 main parts of the circulatory system?
The circulatory system consists of four major components:
- heart.
- arteries.
- veins.
- blood.
Which part of the circulatory system carries blood throughout the body?
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 pumps blood to the body?
heart
Your heart pumps blood around the body all the time – about five litres (eight pints) of it – and this is called circulation. Your heart, blood and blood vessels together make up your cardiovascular system (or heart and circulatory system).
What does blood deliver to every part of the body?
oxygen and nutrients
Blood brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.
What are the 4 pulmonary veins?
There are typically four pulmonary veins, two draining each lung:
- right superior: drains the right upper and middle lobes.
- right inferior: drains the right lower lobe.
- left superior: drains the left upper lobe.
- left inferior: drains the left lower lobe.
Do veins go to the lungs?
The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. The largest pulmonary veins are the four main pulmonary veins, two from each lung that drain into the left atrium of the heart.

What connects the heart to the lungs?
The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
Which is the largest vein?
vena cava
The largest vein in the human body is the vena cava which consists of superior and inferior vena cava.
What is the longest vein in the body?
Great Saphenous Vein
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.
Is aorta a vein or 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.
What is difference between vena cava and pulmonary artery?
Vena cava is a large vein. 2. Aorta is the large artery.
| Pulmonary artery | Pulmonary vein |
|---|---|
| 1. This involves the circulation of blood from the heart to the lungs. | 1. This involves the circulation of blood from lungs to the heart. |
| 2. It carries deoxygenated blood | 2. It carries oxygenated blood. |
What are the 4 main arteries of the heart?
They branch off of the aorta at its base. The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries.
What carries blood away from the heart?
Arteries. Blood vessels that carry oxygenated blood away from the heart to the body.
