It depends on the type of excercise - is it vigorous cardiovascular excercise? Your heart pumps faster, circulating the blood more quickly to your lungs and subsequently the rest of the body. Your blood pressure rises and your skin flushes as the capillaries in your skin dilate to help dissipate heat and keep your body temp at a reasonable level. Your body then determines which organ systems require the most blood supply - in this case the musculoskeletal system. So vessels to your muscles dilate and deliver more blood while the vessels to your kidneys, digestive tract, etc will constrict and receive less blood. That's a very simplistic answer to a complex question.
The short term effect exercise has on blood pressure is to elevate it, the heart has to pump blood more quickly when the body is in motion. This isn't bad health news, however, as the long term effect is a stronger heart and lower blood pressure.
What are the short term effects of exercising on blood flow?
Blood flow increase so as the blood pressure inside the vessels which dilate the vessels upto some extent
redirection of blood flow to exercising tissue
when a person IS exercising, their blood flow speeds up as their heart is pumping more blood around the body, so when a person stops exercising, their blood flow gradually slows down
The blood starts to flow faster.
Carry in oxygen, carry out CO2 and toxins
Studies show that strawberries do help the flow of blood, in which case making it easier to exercise and burn more calories.
Blood vesseld will dilate to allow an increased blood flow to the working muscels and therefore providing more Oxygen.
Go and see a Doctor.
Sweating, panting, and increasing the blood flow underneath the skin.
It stops blood flow.
When exercising in a cold environment the muscle will be cold and oxygen and blood will not flow smoothly during exercise. It is important to dress warmly and warm-up before exercising to prevent injury.
The heart and veins are the parts of the circulatory system that have valves to assist with blood flow.
The kidneys, which are part of the urinary system, may not work as optimally when exercising. This is because the blood flow is restricted.
