Blood vessels alter blood flow by vasoconstriction and vasodilation. Chemicals that mediate vasoconstriction include serotonin and norepinephrine among others. Vasoconstriction works by contraction of smooth muscle lining the vessel walls and narrowing of the lumens of vessels, increasing blood pressure, but also increasing resistance. Chemicals that mediate vasodilation include acetylcholine, epinephrine and nitric oxide. During vasodilation, the muscles lining a vessel relax, increasing the space inside the vessel and slowing the velocity of blood flow. Blood flow velocity is highest in the arterial system, while slowest in the capillaries and venules; constriction increases the velocity of blood flow, while dilation increases blood delivery to the tissues. A system of valves in the lower extremities are used to create a pressure gradient that directs deoxygenated blood back up to the inferior vena cava.

Who is E Gorter?
Eduard Gorter was a Dutch physician and physiologist who is known for his research on blood circulation and muscle physiology. He developed the Gorter model, which describes the relationship between blood flow and muscle metabolism during exercise.
Why test for u and e in blood?
Testing for u and e in blood helps to assess kidney function. Urea (u) and electrolytes (e) measurements can provide information about how well the kidneys are filtering waste products and maintaining the body's balance of electrolytes, such as sodium and potassium. These tests are important in diagnosing conditions that affect kidney health, such as kidney disease or dehydration.

What is the time complexity of the Ford-Fulkerson algorithm for finding the maximum flow in a network?
The time complexity of the Ford-Fulkerson algorithm for finding the maximum flow in a network is O(E f), where E is the number of edges in the network and f is the maximum flow value.
