finlep [7]

Answer:

The blood pressure is directly proportional to the total length of the vessel.

Explanation:

The blood pressure is directly proportional to the total length of the vessel.

The long blood vessel will have higher the resistance and the flow of blood will be lower.

Thus, making intuitive sense, as with blood volume, as the vessel's enhanced surface area will impede blood flow. This lowering area will lead to the higher blood pressure through the blood vessel. Similarly with the reduction in the resistance of the blood vessel, the blood flow will boost.

Identifying relevant information in medical conversations to summarize a clinician-patient encounter
Alex_Xolod [135]

Identifying relevant information in medical conversations does help to summarize a clinician-patient encounter. This is a correct statement.
