The faster your heart beats the faster blood flows.
The heart beats faster when we exercise because the heart pumps more blood and the body also needs more blood
Insulin is a peptide hormone released by the pancreas when glucose levels in the blood rise.
your moving g=faster, causing blood to flow faster and you're creating heat.
Heart beats faster therefore circulating blood faster.
Your heart beats faster because it is pumping blood around your body faster
The pancreas (glucagon) and the adrenal glands (cortisol).
This is certainly true
As you exercise, the muscles need more oxygen to work. The heart beats faster to get the oxygenated blood from the lungs to the muscles. The harder you exercise, the more oxygen the muscles need, the faster the heart beats.
Sure, generally, if your heart beats faster, your blood pressure drops.
When you are excited, your heart rate tends to increase. This is because the stimulation from excitement activates the sympathetic nervous system, which releases adrenaline into your bloodstream. Adrenaline then stimulates the heart, causing it to beat faster and pump more blood to provide the body with energy and oxygen.
More blood is pumped around the body because the heart beats more. When the heart beats more the that makes the blood move around the body faster :)
