What are the main arteries of the heart?

What are the main arteries of the heart?

The 2 main coronary arteries are the left main and right coronary arteries. Left main coronary artery (LMCA). The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium).

Is the vena cava an artery?

Large red vessel (the aorta) – Large artery that carries blood from of the left ventricle to the arteries of the body. Large blue vessel (vena cava) _(includes the superior and inferior vena cava) – _Large vein that empties blood into the right atrium of the heart.

What’s the difference between the vena cava and the artery?

Vena cava are large diameter tubes. The blood which carries by the vena cava is darker due to the absence of oxygen. The blood pressure of the vena cava is lower compared to the arteries. What are the Similarities Between Aorta and Vena Cava?

What is the function of the superior vena cavae?

The superior and inferior venae cavae play a vital role in blood circulation as they return oxygen-poor blood to the heart for re-oxygenation and recirculation. Superior Vena Cava: This large vein brings de-oxygenated blood from the head, neck, arm, and chest regions of the body to the right atrium.

Where does the superior vena cava receive the azygous vein?

At the level of T4, the superior vena cava receives the azygous vein, which drains the upper lumbar region and thoracic wall. The superior vena cava is a thin-walled, low pressure vessel which makes it vulnerable to compression.

Where does the right gonadal vein join the vena cava?

The right gonadal vein (ovarian in females and testicular in males) joins the inferior vena cava just inferior to the level of the left renal vein at an acute angle. It opens into its right anterolateral aspect and is usually double in its course.

What kind of blood is in the vena cava?

There are two main veins which mainly bring deoxygenated blood to the heart. They are superior vena cava and inferior vena cava. These two are also known as precava and postcava. Superior vena cava brings oxygen-depleted blood from head, neck, arms and upper body.

What’s the difference between the aorta and the vena cava?

Aorta and vena cava are the two types of main blood vessels attached to the heart. Aorta is the main artery of the body while the two main veins of the body are superior and inferior vena cava.

Where does the inferior vena cava enter the heart?

The inferior vena cava is one of the two main veins bringing de-oxygenated blood from the body to the heart. Veins from the legs and lower torso feed into the inferior vena cava, which empties into the right atrium of the heart.

Which is the main vein in the body?

Vena Cava is the main type of veins in the body. Aorta is attached to the left ventricle of the heart. Vena Cava is attached to the right atrium of the heart. Aorta carries oxygenated blood throughout the body. Vena Cava returns deoxygenated blood from the body into the heart. Aorta: A single aorta begins at the left ventricle.
