Arteries and veins are anatomical terms. Arteries Always carry blood Away from the heart and veins carry blood back. If these are veins coming to the heart from the lungs, they must be rich in oxygen.
The blood flows towards the heart.
'''Arteries, Arterioles, Capillary beds, Venules, Veins'''
Veins have valves to make sure that blood flows in only one direction.
No. (Not counting the pulmonary veins) the least "deoxygenated" blood is in the renal veins and the jugular. (Neither the brain nor the kidneys use up all the oxygen in their blood supply.) Blood flow to the skin is sometimes controlled by temperature - heat to be lost - and MAY be less desaturated.
The Pulmonary Semilunar Valve allows blood from the right atrium into the pulmonary trunk.
In the arteries it is away from the heart (centrifugal), in the veins it is toward the heart (centripetal).
toward the heart from the lungs
Yes, blood leaving the lungs via the pulmonary veins goes into the left atrium.
The path of blood flow starting at the pulmonary veins: -pulmonary veins -left atrium -bicuspid valve -left ventricle -Pulmonary semi lunar valve -Aorta
They all are veins and the blood in them all flow toward the heart
Veins.
Valves
toward the heart if deoxegen
Deoxygenated blood is in the systemic veins. The pulmonary veins carry oxygenated blood to the heart to be pumped to body tissues.
'''Arteries, Arterioles, Capillary beds, Venules, Veins'''
there are two main veins that makes the blood flow toward the heart which are the superior vena cava and inferior vena cava.
Veins have valves to make sure that blood flows in only one direction.
Blood flows from the right ventricle of the heart into the lungs through the pulmonary arteries that carry deoxygenated blood. From the lungs, oxygenated blood flows through the pulmonary veins to the left atrium of the heart.
