What is meant by eustachius valve?
This is the valve of the vena cava inferior and the right atrium, also known as the valvula venae cavae inferioris. It is shaped like a half moon.
Function of the frog right atrium?
Definition: the right upper chamber of the heart that receives blood from the venae cavae and coronary sinus
How do atria and ventiricles differ in structure and function?
Function of the Atria The atria of the heart receive blood returning to the heart from other areas of the body. Right Atrium: Receives blood returning to the heart from the superior and inferior venae cavae. The superior vena cava returns de-oxygenated blood from the head, neck, arm and chest regions of the body to the right atrium. The inferior vena cava returns de-oxygenated blood from the lower body regions (legs, back, abdomen and pelvis) to the right atrium. Left Atrium: Receives blood returning to the heart from the pulmonary veins. The pulmonary veins extend from the left atrium to the lungs and bring oxygen-rich blood back to the heart.
What is the function of each atrium?
the main or central room of an ancient roman house open to the sky with a pool for collecting water. A large open space in a building Microscopic air sacs within the lungs An anatomical structure within the heart Atrium of the ventricular system of the brain (a cavity or passage in the brain)
Path of blood flow through the systematic circulation?
There are two circulations: pulmonary which goes from heart to lung and back to the heart, and the systemic which supplies the rest of the body.Blood from the body travels through the veins to the vena cava and the right atrium of the heart. It is pumped by the right ventricle through the pulmonary arteries to the lungs. From the lungs, the blood flows back to the heart through the pulmonary veins, enters the left atrium, and is pumped by the left ventricle out through the aorta, and through the arteries to the body.
Inferior venae cavae?
one of the vein that is leading toward the heart.
What vessel empties into the upper right chamber of the heart?
The superior and inferior venae cavae.
What is the first heart chamber to receive blood from the superior and inferior venae cavae?
Right Atrium
What do veins merge to become?
The ones returning blood to the heart from the body tissues eventually merge to become the inferior and superior venae cavae.
What is vena cava plural?
venae cavae
What is the blood vessel?
Venae cavae are the largest two.Aorta

Which chamber of the heart do venae cavae empty into?
right atrium
Blood returns to the heart from systemic circulation through the?
venae cavae
Where does the venae cavae lead in to?
starts at brain ends at heart you have the upper which is the bigger and the lower which is the smaller
Compare the thickness of the walls of the superior and inferior vena cava and the aorta?
The aorta has significantly thicker walls than the superior and inferior venae cavae as the aorta is an artery that must respond to significant intraluminal pressures whereas the venae cavae are veins that have minimal intraluminal pressure.
