Sure, but not in any organised way. Thing is, some sorts of cells might die in the presence of blood. Not having blood vessels could be very limiting for more complex or bigger lifeforms.
the type of blood vessels which flow contaminated blood to the heart are known as VEINS
Yes.
Blood vessels. Constriction of blood vessels increases blood pressure by reducing the space for blood flow, while dilation of blood vessels decreases blood pressure by increasing the space for blood flow.
you crazy 니
so that the blood cannot flow the wrong way through the vessels
Sympathetic vasoconstriction decreases blood flow by narrowing blood vessels, while sympathetic vasodilation increases blood flow by widening blood vessels.
The heart is a pump and move blood through the blood vessels.
by blood vessels
Intercostal is a set of blood vessels. The blood vessels gives blood flow to the ribs.
Contractions of blood vessels can affect blood flow. Constricting (narrowing) of blood vessels reduces blood flow, while dilating (widening) of blood vessels increases blood flow. This regulation is important for controlling blood pressure and directing blood to different parts of the body based on its needs.
