Final answer:
The normal range for red blood cell count for adult males is 42 to 52, with a mean of 47, and for adult females, it is 37 to 47, with a mean of 41. These values express the percentage of blood volume that is red blood cells.
Step-by-step explanation:
Normal Red Blood Cell Counts for Adults
The normal range for red blood cell count varies by gender due to physiological differences. For an adult male, normal hematocrit values range from 42 to 52, with a mean of 47. This means approximately 42-52% of their blood volume is comprised of red blood cells. For an adult female, normal hematocrit values range from 37 to 47, with a mean value of 41, indicating that 37-47% of their blood volume is made up of red blood cells.
It's important to note that these values are approximate and can be influenced by various factors including age, altitude, smoking habits, and certain medical conditions. Deviations from the normal range may necessitate further medical investigation to determine the underlying cause.
