What type of blood vessel is the vena cava?

What type of blood vessel is the vena cava?

What type of blood vessel is the vena cava?

The vena cava are the two largest veins that carry blood into the right upper chamber of the heart (the right atrium). The superior vena cava carries blood from the brain and arms into the top of the right atrium.

Is the vena cava afferent or efferent?

Cardiovascular/Respiratory

Question Answer
Is the vena cava an afferent or efferent blood vessel? Afferent
Is the aorta an afferent or efferent blood vessel? Efferent
Is the blood in the aorta oxygen rich or oxygen poor? Oxygen Rich
Is the blood in the vena cava oxygen rich or oxygen poor? Oxygen Poor

What are afferent blood vessels?

The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems. They play an important role in the regulation of blood pressure as a part of the tubuloglomerular feedback mechanism. The afferent arterioles branch from the renal artery, which supplies blood to the kidneys.

Is vena cava a great vessel?

The Great Vessels of the Heart. There are a number of great vessels associated directly with the heart. These are the ascending aorta, the pulmonary trunk, the pulmonary veins, the superior vena cava, and the inferior vena cava. These two large veins both drain into the right atrium of the heart.

Where does blood leaving the afferent Arteriole go to next?

Each nephron is served with blood by the afferent arteriole. This vessel brings blood into a capillary tuft called the glomerulus. Blood leaving the glomerulus flows into the efferent arteriole. Usually an arteriole flows into a venule.

Which arteriole has more diameter?

afferent arteriole
Explanation: The afferent arteriole is the arteriole that brings blood to the glomerulus. It is larger in diameter than the efferent arteriole. The efferent arteriole is the arteriole that carries blood away from the glomerulus.

What happens if the afferent arteriole is vasoconstriction?

Constriction of the afferent arterioles has two effects: it increases the vascular resistance which reduces renal blood flow (RBF), and it decreases the pressure downstream from the constriction, which reduces the GFR. Constriction of the efferent arterioles also increases the vascular resistance so it reduces RBF.

What happens if the afferent Arteriole is vasoconstriction?

Which organ does not excrete waste?

The kidneys are the only means for eliminating the wastes that are the end products of protein metabolism. They do not themselves modify the waste products that they excrete, but transfer them to the urine in the form in which they are produced in other parts of the body.

Which arteriole has a smaller diameter?

efferent arteriole
The efferent arteriole is the arteriole that carries blood away from the glomerulus. It is smaller in diameter than the afferent arteriole.
