Is the number of people with blood type a in a random sample of 34 people?
To determine the number of people with blood type A in a random sample of 34, you would first need to know the prevalence of blood type A in the population. In general, approximately 26% of the population has blood type A. Therefore, in a random sample of 34 people, you could expect about 8 to 9 individuals to have blood type A, though the actual number may vary due to random sampling.
What do the 2 numbers in blood pressure represent?
The first number in a blood pressure reading is the systolic blood pressure. It represents the pressure in the artery when the heart is contracting. The second number is the diastolic blood pressure, and represents the pressure when the heart is relaxing.
Why blood pressure is expressed with two number?
When a blood vessel (like an elastic pipe) is empty there is no pressure on its wall. When there is blood flowing in a blood vessel it exerts pressure on the walls of the blood vessel (pipe). This is the basal pressure called the Diastolic pressure (The lower of the two numbers). When the heart pumps blood it drives the blood with force and this exerts higher pressure on the walls of the blood vessel. This is called the Systolic pressure, the higher number in the blood pressure measurement. Thus, Blood Pressure of 120/70 means the systolic pressure is 120 and the diastolic pressure is 70.
What blood pressure is the force of blood on the?
The blood pressure is the pressure in the arteries created by the large quantity of blood circulating in them. The number on the top is the systolic blood pressure and the number on the bottom is the diastolic blood pressure. The systolic BP is the pressure in the arteries right when the blood is pumped out of the heart, therefore the pressure is bigger. The diastolic BP is the pressure in the arteries after the blood has been pumped out and before the next heart contraction. At this moment, the heart is relaxed and the pressure is much lower.
What does the 3 numbers blood pressure reading mean?
A blood pressure reading consists of two numbers: systolic pressure (the top number) and diastolic pressure (the bottom number). The systolic pressure measures the pressure in the arteries when the heart beats, while the diastolic pressure measures the pressure in the arteries when the heart is at rest between beats. The third number, if present, is the pulse pressure, calculated by subtracting the diastolic pressure from the systolic pressure. This number gives an indication of the force the heart generates with each contraction.
What is the highest pressure exerted by blood in your arteries called?
The upper Blood Pressure Number is the Systolic, Which is the force of blood in your arteries when you heart beats.
In what units is blood pressure read?
Systolic pressure is the upper number and diastolic pressure is the lower number.
120 over 80 blood pressure what is the first number?
The first number is called your systolic blood pressure and the second is called your diastolic. The Systolic is the pressure in your arteries when the ventricles are contracting - so it is the maximum pressure that the heart exerts on the arteries. The diastolic is the pressure when the heart is relaxed - so it is the minimum amount of pressure.
What is the difference between systolic pressure and diastolic pressure?
systolic pressure when ventricals are contracting while during diastole they are in relaxed state
Is always ok when do blood pressure number comes out an even?
normal blood pressure reading
What is the highest pressure against the blood vessels?
systolic, its the number on top, that's why that number is larger
What is resting blood pressure?
Resting Blood Pressure: Diastolic (blood filling into atrium of heart) is the top number Systolic (blood pumping from atrium into ventricles of heart) is the bottom number
