During a contraction, the flow of oxygen (from the mother) through the placenta (to the baby) is temporarily stopped
Increase
Ecosprin 75 is used to prevent venous thromboembolism (VTA) or blood clots. This medicine helps to decrease the chance of placenta related complications. Before pregnancy it helps to increase blood flow to the uterus.
increase in the diameter of blood vessel. it increases the blood flow
Blood flow can be increased in two main ways: firstly, the heart can pump blood round the body at a faster rate i.e. by increasing blood flow. Secondly, vasodilation can take place, by which blood vessels "expand" in order to allow more blood to pass through. This process is mainly used during exercise, when our body needs to lose excess heat energy.
CDS has proven extremely useful for evaluating the blood flow to the placenta and uterus during pregnancy
vasoconstriction
Except in cases of massive blood loss, it's not the job of the vessels to increase or decrease blood flow, but of the capillary beds.
Is increase in blood pressure in the capillaries
Expand
Some medications increase blood flow, like inotropics. Others, like vasoconstrictors, may decrease blood flow.
