D
3000
Verified step by step guidance1
Step 1: Understand the concept of total lung capacity (TLC). Total lung capacity refers to the maximum amount of air the lungs can hold after a full inhalation. It is the sum of all lung volumes, including tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume.
Step 2: Recall the average total lung capacity for males. In general biology, it is commonly stated that the normal total lung capacity for males is approximately 6000 mL. This value is based on physiological studies and averages across populations.
Step 3: Compare the given options to the average total lung capacity for males. The options provided are 6000 mL, 4500 mL, 12000 mL, and 3000 mL. Identify which value aligns most closely with the normal range for males.
Step 4: Eliminate incorrect options. For example, 12000 mL is too high and exceeds the physiological capacity of the lungs, while 4500 mL and 3000 mL are too low to represent the total lung capacity for males.
Step 5: Select the correct answer based on the comparison. The correct value should match the normal total lung capacity for males, which is approximately 6000 mL.
