What else can I help you with?
In mammals what will blood returning from the head pass through just before entering the right atrium?
Blood returning from the head in mammals will pass through the superior vena cava just before entering the right atrium.
Sequence of parts through which blood moves in passing from the venae cavae to the lungs?
starting from the Veins Vein (unoxygenated) (e.g Inferior Vena cava) > right atrium > right ventricle > Pulmonary truck > Pulmonary Arterys > Lungs (to become oxygenated) > Pulmonary Veins (now oxygenated) > left Atrium > left ventricle > aorta > to the arteries in the body > arterioles > capillaries > venules > veins (where the oxygen is again replaced by coz and is thus unoxygenated) (the cycle repeats itself)
Which blood vessel has the lowest concentration of oxygen?
The circulatory system contains high pressure vessels called arteries which come from the heart and then the capillaries where gas and nutrient exchange ocurrs. From there veins form and they come back to pick up more. The veins are high volume but low pressure vessels. Arteries are lower volume and higher presure vessels. See the video below for good information.
What happens in the right atrium?
The atria are the two upper chambers of the heart (the ventricles are the lower two) The atria are the 'filling' chambers, so blood entering the heart passes through the atria first, which then push it down into the ventricles. The two largest veins in the body (the superior and inferior venae cavae) empty deoxygenated blood returning from the body into the right atrium. The right atrium then contracts, pushing the blood into the right ventricle. The right ventricle then pumps the deoxygenated blood to the lungs where it is oxygenated. After leaving the lungs, the newly oxygenated blood is returned via the pulmonary veins into the left atrium. The left atrium then contracts and pushes the blood into the left ventricle, which pumps the oxygenated blood around the rest of the body.
Is Systemic Circulation oxygen poor blood?
No, systemic circulation carries oxygen-rich blood from the heart to the body tissues and then returns oxygen-poor blood back to the heart. This blood flow is essential for delivering oxygen and nutrients to cells, as well as removing waste products like carbon dioxide.

What does the largest vein in your body do?
The largest veins are the venae cavae that return deoxygenated blood from the body into the heart.
If the Venae cavae clogged vhat is going to happen vith the blood?
Edward Cullen comes and drinks it up.
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 the sequence of valves in the pathway of blood from the venae cavae to the aorta is?
-tricuspid valve -pulmonary semilunar valve -mitral/bicuspid valve -aotic valve
