aerobic respiration
Heart rate increases.
the heart increases in rythm and pumps more blood to the muscles
running
During exercise our blood circulation speed increases. It effect in amino acid and a molecule ATP which causes muscles to increase strength.
bone stimulation
lactate
The pressure in the pulmonary artery increases during exercise if the cardiac output increases.
Because during exercise more oxygen is required , so more blood is pumped to meet the requirement.
it increases
During exercise, mean arterial pressure typically increases due to the body's increased demand for oxygen and nutrients. This is because the heart pumps more blood to deliver these essential substances to the muscles and organs that are working harder during physical activity.
It INCREASES.
Yes, blood flow increases during exercise to deliver more oxygen and nutrients to the muscles and remove waste products.
