Question

There are four main factors that influence blood pressure. Select the correct four factors from the following options:

	a.	Blood volume, blood pressure, the strength of each heart contraction, heart rate
	b.	Blood volume, the strength of each heart contraction, heart rate, thickness of the blood
	c.	Blood pressure, blood volume, the strength of each heart contraction, heart rate
	d.	Blood volume, the strength of each heart contraction, heart rate, stroke volume

Answer 1

Ans b.

Blood volume, the strength of each heart contraction, heart rate, thickness of the blood

Changes in blood volume affect arterial pressure by changing cardiac output. An increase in blood volume increases central venous pressure. This increases right atrial pressure, right ventricular end-diastolic pressure and volume.

also called heart rate, refers to the number of times your heart beats in one minute. Typical pulse measurements range from 60 to 100 beats per minute.

Blood pressure is an estimate of the force your blood is exerting on your blood vessels. A typical value for blood pressure is 120/80. Doctors consider blood pressure to be elevated when it’s between 130 and 139 systolic (the top number) over 80 to 89 diastolic (the bottom number).

Symptoms of thick blood may include lightheadedness, blurred vision, and headaches. A hypercoagulability problem with a person's blood is often symptomless and will first show as a blood clot and excessive menstrual bleeding or clotting. high blood pressure.
