Each isotope has a special name derived from Latin (protium, deuterium, and tritium). What structural feature do these names ref
Eduardwww [97]

An isotope of any element is the same, with a variation in the neutrons of the nucleus.

The mass number change but the atomic number doesn't.

In this case, protium, deuterium, and tritium are all hydrogen isotopes.

Protium is 1H or Hydrogen-1 is without neutrons.

Deuterium is 2H  or Hydrogen-2 has one neutron.

Tritium is 3H or Hydrogen-3 has two neutrons.

dem82 [27]

Answer: Systolic pressure.

Explanation:

Every time the heart beats, it pumps blood into the arteries, which are vessels through which blood circulates from your heart to your tissues with the oxygen and nutrients they need. Blood pressure is the force of the blood pushing against the walls of the arteries, and is highest when the heart beats, pumping blood, which is measured as systolic pressure (i.e., when the heart contracts). On the other hand, diastolic blood pressure refers to the pressure of blood in the artery when the heart relaxes between beats (i.e., when the heart relaxes). Since there are two types of pressures, blood pressure readings are given in two numbers, with the top number being the systolic pressure and the bottom number being the diastolic pressure.  

For example, if the systolic pressure measured in a person is 125 millimeters of mercury (mm Hg) and the diastolic pressure is 85 mm Hg, the blood pressure is recorded as 125/85.  

So, <u>the systolic blood pressure is registered with the stethoscope when the cuff is deflated.</u> When two heartbeats are heard, the pressure gauge reading is recorded. <u>When the heartbeat ceases, the cuff pressure is released and the diastolic pressure is measured at this time.</u>
