Physiology. Amylase is a calcium dependent enzyme which hydrolyzes complex carbohydrates at alpha 1,4-linkages to form maltose and glucose. Amylase is filtered by renal tubules and resorbed (inactivated) by tubular epithelium. Active enzyme does not appear in urine.
The prostate is an accessory sex gland that surrounds the urethra and neck of a male dog's bladder. The prostate gland produces a fluid that helps nourish and transport sperm. Benign prostatic hyperplasia is a condition in which the prostate gland is enlarged. The word hyperplasia means increased in size.
Facts about the prostate gland. The prostate gland is about the size of a walnut. It's located just below the bladder and it surrounds the urethra (a tube that carries urine and semen out of the body). The prostate is partly muscular and partly glandular, with ducts opening into the prostatic portion of the urethra. It is made up of three lobes: a central lobe with one lobe on each side.
