how does the urinary system support reproduction and passing on genetics?

Without a functioning urinary system, we'd be dead. We can't reproduce and pass on our genes if we're dead.

The urinary system and the reproductive system are two separate systems in the human body with distinct functions. However, they can indirectly support each other in maintaining overall reproductive health. Let's break it down:

1. Waste Removal: The urinary system, which includes the kidneys, ureters, bladder, and urethra, is primarily responsible for removing waste products from the blood and excreting them as urine. This process helps maintain the balance of electrolytes and chemicals within the body. Proper waste removal also ensures that harmful substances do not accumulate and potentially negatively impact reproductive organs.

2. Hormone Clearance: The urinary system plays a role in eliminating certain hormones, such as estrogen and testosterone, from the body. By clearing these hormones, the urinary system helps regulate their levels, which is vital for the proper function of the reproductive system. Hormonal imbalance can interfere with fertility and reproductive health.

3. Preventing Infections: The urinary system helps to prevent infections, such as urinary tract infections (UTIs), in the reproductive system. UTIs can have detrimental effects on the reproductive organs, leading to complications like pelvic inflammatory disease (PID), which can impact fertility.

Although the urinary system indirectly supports reproduction by maintaining overall health and preventing issues that could affect the reproductive system, it does not directly contribute to passing on genetics. The passing on of genetics primarily occurs through the reproductive system, specifically through processes such as sexual intercourse and fertilization.
