What happens to the rate of blood delivery if your heart rate increases?(1 point) Responses Blood delivery rate increases Blood delivery rate increases it has no impact on blood delivery rate it has no impact on blood delivery rate Blood delivery rate decreases
Blood delivery rate increases
The rate of blood delivery increases if your heart rate increases.
When your heart rate increases, the rate of blood delivery also increases. This is because the heart pumps more blood with each beat, leading to a higher volume of blood being circulated throughout the body per unit of time. To understand this, you can think of the heart as a pump and the blood as the fluid being pumped. When the pump (heart) works faster, it increases the flow rate of the fluid (blood). Therefore, an increase in heart rate directly corresponds to an increase in the rate of blood delivery.
