Answer 1

Correct Answer: 300-600ml

Rationale:

The normal bladder capacity in healthy adults typically ranges from 300-600ml. This is the volume of urine the bladder can hold comfortably before the urge to urinate is felt. While this range can vary slightly among individuals, it is considered the standard capacity under normal physiological conditions.
The bladder is a hollow, muscular organ that stores urine produced by the kidneys. It gradually fills over time, and as it reaches its capacity, nerve signals are sent to the brain, prompting the sensation of needing to urinate.
Factors such as age, hydration levels, and overall health can influence bladder capacity. For example, older adults may experience reduced bladder capacity due to age-related changes in bladder elasticity and muscle tone.

Explanation of Other Options:

100-300ml

Rationale: This range is too low to represent the normal bladder capacity in a healthy adult. Bladders with such a low capacity may indicate underlying medical conditions, such as an overactive bladder or bladder dysfunction.

600-900ml

Rationale: Although the bladder can stretch to hold larger volumes, this is beyond the normal comfortable capacity. Holding urine for prolonged periods at such volumes can lead to discomfort and potential complications, such as urinary tract infections (UTIs) or bladder distension.

900-1000ml

Rationale: A bladder capacity this high is abnormal and can occur in cases of chronic urinary retention or neurological conditions that impair bladder function. Such high volumes can strain the bladder muscles and lead to long-term damage.

No Option Provided

Conclusion:

The normal capacity of the bladder in a healthy adult is approximately 300-600ml. This range allows the bladder to function efficiently without discomfort. It is important to maintain good urinary habits, including regular voiding, to prevent complications related to overdistension or underuse of the bladder.
