The relationship of blood flow (Q), resistance (R), and pressure (P) in a vessel can be expressed by which equation?
A. Q = P/R.
B. Q = R/P.
C. Q = PQ.
D. P = Q/ R
Answer:
A. Q = P/R.
Explanation:
Resistance is the force that counteracts the blood flow and slows down the speed of the blood flow. It occurs due to friction between blood and the walls of blood vessels. Resistance is regulated by the size of the blood vessels, length of the blood vessels and viscosity. Blood always flows from the region of the higher blood pressure towards the lower one. Therefore, blood flow is directly proportional to pressure and is indirectly proportional to the resistance.
So, Q= P/R
Because when exercising your heart pumps more blood to your body and
it has more space to fill so it beats faster
Yes you are correct. Nice job!
