pair of kidneys, the ureters, the bladder, and the urethra. The kidneys provide a blood-filtering system to remove many waste products, and to control water balance, pH, and the level of many electrolytes. The kidney filtrate is urine, which is conveyed to the bladder by the 2 ureters. From there it is evacu-ated via the urethra. Proper urinary functioning avoids kidney failure and all its consequences: swelling, toxicity, and weight loss.
The Reproductive System
The reproductive system ensures the continuation of the species.
The male reproductive system consists of the testicles, the acces-sory glands and ducts, and the external genital organ. The female reproductive system consists of the ovaries, oviducts, uterus,

The Skeletal System
The skeletal system serves as a framework for the horse’s body, giving the muscles something to work against, and defining the animal’s overall size and shape. The skeleton also protects the horse’s vital internal tissues and organs. For example, the skull protects the brain; the rib cage protects the lungs and heart; the vertebral column protects the spinal cord.The
