Blood pressure and pulse

Systolic blood pressure, diastolic blood pressure, and pulse (or heart rate) are the readings we see on our monitors. And although we quite understand what each term means, we have difficulty understanding the relationship between them. Let’s clear these up.
To have a common understanding, we will use the following loose definitions.
As we mention in the effective blood pressure log, systolic blood pressure is the pressure that the blood exerts on the arteries when the heart contracts (contract in Greek is “systellomai,” hence the term) to push the blood throughout your body.
Diastolic pressure is the pressure exerted by the blood on the arteries when the heart dilates (dilate in Greek is “diastellomai,” hence the term) after its contraction. It obviously has lower values than those of systolic, which is why it is also called “low” in contrast to the systolic, which is also called “high.”
On the other hand, the pulse is the number of times our heart beats per minute. We consider as normal a resting heart rate of 50 to 100 beats per minute for most adults. People who exercise regularly usually have lower resting heart rates.
Both blood pressure and pulse can change based on activity level, age, medication, and other factors throughout life. Usually, blood pressure increases with age, but pulse does not.
Somebody reasonably would think that during hard physical activity that necessarily increases the pulse would also increase BP since more blood should pass from the same vessels. But if the vessels are healthy, they expand in size, and the blood pressure remains almost stable.
Can you see how critical it is to watch these parameters? What would be your conclusion if you observe that your BP and pulse are positively correlated, meaning when one increases, the other increases too, for a long time?
