the phenomenon in which hypoxic (and thus radioresistant) tumor cells become more exposed to oxygen (and thus more radiosensitive) by coming into closer proximity to capillaries after death and loss of other tumor cells due to previous irradiation.

What are the veins function?
To allow the blood to get back to the heart to be reoxygenated.
What is the function of the superior venacava?
The superior venacava navigates deoxygenated blood back to the heart to get reoxygenated
What are the blood vessels that direct blood to the heart?
Veins - return deoxygenated blood to the heart to be reoxygenated. In contrast to arteries that bring the oxgenated blood from the heart, to the rest of the body for use.
What brings blood to the lungs for gas exchange?
The heart pumps blood to the lungs to be reoxygenated. Valves in our veins and the muscle contractions of our legs helps bring blood from the lower limbs to the heart.
What is the function the right ventricles?
The right ventricle receives blood that has circulated through the body via the right atria. it then pumps the blood through the pulmonic valve to the lungs where the blood becomes reoxygenated for circulation. :)
Which does not carry oxygenated blood?
All arteries (the red blood vessels) carry oxygenated blood. it's the viens (the blue blood vessels) that don't carry oxygenated blood. However the Pulmonary artery carries Deoxygenated blood to the lungs to be reoxygenated, as it carries blood away from the heart it is called a Artery.
Why does the right side of the heart have deoxyenated blood?
The right side of the heart receives blood which has already been pumped around the body and has had all its oxygen used up. The right side of the heart pumps deoxygenated blood through the lungs where it is reoxygenated.
Why cant you say that arterys carry oxygenated blood?
Because although most arteries do carry oxygenated blood, there is one exception - the pulmonary arteries. These take deoxygenated blood from the heart to the lungs so it can be reoxygenated. It is more accurate to say that arteries carry blood away from the heart.
Why Blood is pumped by the brain?
Veins running back to your heart from your ear! Jk, the Veins flow thru your neck and the blood is reoxygenated to continue its cycle.
What is the function of a Right Atrium?
The function of the right atrium is to receive deoxygenated blood from the body (through the superior and inferior vena cavae, and the coronary sinus) and pump it into the right ventricle, which then pumps it to the lungs to be reoxygenated.
Which artery doesnt carry oxygen?
All arteries (the red blood vessels) carry oxygenated blood. it's the viens (the blue blood vessels) that don't carry oxygenated blood. However the Pulmonary artery carries Deoxygenated blood to the lungs to be reoxygenated, as it carries blood away from the heart it is called a Artery.
What are three parts of the cardiovascular system?
-Capillaries bring blood and nutrients to every cell. They are smaller than your hair. -Veins bring non-oxygenated blood back to the heart, so that the blood can become reoxygenated. -Arteries take the blood straight from your heart. They are very flexible so that they will not break every time the heart pumps blood.
