Because it is convenient. You could actually separate them and study them individually. But, since both functions occur with many of the same physiological components, many teachers choose to teach them at the same time.
Another reason may be because the excretory system is not really a system to itself because many systems of the body contribute to excretion.
excretory means: things that come out of you ( a.k.a feces ) reproductive means: doing the dirty ( a.k.a making babies ) so they work together like this... reproductive system makes the babies.... the excretory system makes the baby out!
I'm afraid I don't have a full answer to that, its a very deep question in terms of the evolutionary past but I can answer in a general way. Evolution can be very haphazard and nonsensical. Perhaps they have never been separate and it would be counter productive to rearrange things now. Once something has evolved into a certain form it cannot get worse to get better.
My 2cents hope this helps a little.
Because the bladder is connected to other organs that produce sperm and filter out urine during ejaculation. Urine passes through from the bladder to the prostate via the urethra prior to ejaculation. The urine helps in formation of the ejaculation fluid.
The products of the male reproductive system (semen) and the urinary systems (urine) come out same place. Both products are deposited through the urethra. The end of the urethra can be seen as an opening at the tip of the penis.
They works together to remove waste in the body such as urine.
They don't actually work together the reproductive system just happen to be in the same area as the place where the urine leaves the body.
The pulmonary and renal mechanism work together to support the chemical buffer system through bringing the body into a state of homeostasis as the kidney helps to maintain the acid-base balance by excreting either an acid or an alkaline in urine or through respiration.
There are eleven organ systems, which work together to help organisms meet their basic needs and survive: Circulatory system Reproductive system Endocrine system Lymphatic system Skeletal system Muscular system Nervous system Urinary system Respiratory system Digestive system integumentary system
When different organs work together, they work together as a system.

A system is a group of organs that work together like the digestive system. While a body is a group of systems that work together. You are not just your digestive system but also your musculoskeletal system, urogenital system, endocrine system and nervous systems that work all together.

The reproductive system. It is different in males than it is females.
The organs work together by
All the systems work together in the body not one of them dont because that is how we stay alive
The Reproductive System The reproductive system is a system of organs within an organism which work together for the purpose of reproductive. Female Reproductive System The human female reproductive system is a series of organs primarily located inside the body and around the pelvic region of a female that contribute towards the reproductive process. It is designed to transport the ova to the site of fertilization.production of androgen and by production of spermEr, reproduction.
At puberty, the reproductive system starts producing hormones that cause the skeletal system to mature. The female pelvis also widens to eventually accommodate a baby's head during birth.

All organ systems work together in order for a body to function. The circulatory system and the excretory system work together to rid the body of wastes. As blood travels to the kidneys, unneeded materials are filtered out through the rest of the excretory system and the filtrated blood is carried away via the Renal vein.
