Anatomy Of The Female Urogenital System Of The West African Giraffe (Giraffa Camelopardalis Peralta)

The knowledge of the anatomy of organs of the urogenital system is vital in understanding aetiologies of anomalies. To this end, morphology and morphometry of the organs of reproduction and urine formation, from autopsies of two adult non-gravid West African giraffes (Giraffa camelopardalis peralta) at the Faculty of Veterinary Medicine, University of Ilorin, Ilorin, Nigeria were studied. In situ, two encapsulated kidneys were found to be retroperitoneal and asymmetrically pressed against the dorsal abdominal wall on each side of the

The Remarkable Cardiovascular System of Giraffes

Gravity affects the physiology of many animals, and the effect is, for good reason, most pronounced in tall species. The physiology—in particular, cardiovascular function—of giraffes has therefore captivated the interest of physiologists for centuries. Several studies document high mean arterial blood pressure of giraffes of about 200 mm Hg. This appears necessary to establish a cerebral perfusion pressure on the order of 100mmHg at the cranial end of the carotid arteries. Here, we discuss the unique characteristics of blood vessels,

Kidney of Giraffes

This study focuses on certain aspects of the renal structure of the giraffe, with some implications as to its function. About 4,000 collecting ducts open at the truncated end of a curved crest that juts into the renal pelvis as the inner medulla (IM). Extensions of the pelvis pass between the medullary (MP) and vascular (VP) processes almost to the corticomedullary border. The MPs contain an IM and an outer medulla (OM) containing clusters of capillaries (vascular bundles). The VPs
