Just like human males, both urinary and genital tract are linked to the same pathway for male rabbits. Like human females, the urinary tract and genital tract are in different pathways for female rabbits, but they join together at the urinary bladder.
Thus rabbits have a combined urinary and reproductive systems. Hence the system is called a urinogenital system. In this object, a urinogenital system of the rabbit is explained.
The urinogenital system in rabbits consists of:
- Urinary or excretory system
- Genital or reproductive system
Excretory system of rabbit:
There are numerous nephrons in each kidney. It removes nitrogenous wastes from the blood and excretes them as urea.
The structure of mammals nephron
Kidneys are bean-shaped organs with a dark red colour that are located in the abdominal cavity. The ureters emerge from each kidney, opening posteriorly into the urine bladder and leading into the urethra, a thick-walled muscular duct.
Reproductive system of rabbit:
Important!
Rabbits demonstrate sexual dimorphism. Male and female sexes are distinct and morphologically distinct.
Male reproductive system:
The rabbit's male reproductive system consists of a pair of ovoid-shaped testes. Scrotal sacs in the abdominal cavity contain the testes. Seminiferous tubules are a type of tiny tubule found in each testis. These network of tubules leads to the epididymis, a coiled tubule that leads to the vas deferens, the sperm duct.
Just below the urinary bladder, the vas deferens merge in the urethra. The urethra enters the penis and flows backwards. The prostate gland, Cowper's gland, and the perineal gland are the three accessory glands. Their secretions aid reproduction.
Female reproductive system:
A pair of ovaries, small oval structures, make up the rabbit's female reproductive system. They are found in the abdominal cavity, behind the kidneys.
Each side of the ovary has a funnel-shaped aperture that leads to a pair of oviducts that open into the body cavity. The fallopian tube is the oviduct's anterior portion. It connects to the uterus, which is a larger tube.
The uterus joins to produce a vaginal tube in the middle. The urinogenital canal, also known as the vestibule, is produced by connecting the urine bladder and the vagina. It runs backwards and has a vulva-like orifice that opens to the outside.
Important!
The accessory glands in the female reproductive system are a pair of Cowper's glands and a perineal gland.
