Answer 1

Answer: Y: Cardiac output; Z: A phase in which in which the heart contracts

Explanation: this has to do with cardiovascular system heart rate is where how many beats heart is beating per second and your intensity. if the blood is being pumped then is contracting in order for your hearts blood to be pushing thru. it must contract for the blood to pump in one minute
