Pressure profile and morphology of the arteries along the giraffe limb
TLDR
The sudden narrowing was also observed in the hind legs of neonates, indicating that it does not develop as an adaptation to the high transmural pressure in the standing giraffe, more likely it represents a preadaptation to thehigh pressures experienced by adult giraffes. Expand
Left Ventricular Morphology of the Giraffe Heart Examined by Stereological Methods
TLDR
A quantitative structural study of the LV myocardium in young and adult giraffe hearts suggests the presence of myocyte proliferation during growth of the animal to increase wall thickness and normalize LV wall tension as the neck lengthens and the need for higher blood pressure ensues. Expand
The thick left ventricular wall of the giraffe heart normalises wall tension, but limits stroke volume and cardiac output
TLDR
It is concluded that, relative to body mass, a small left ventricular cavity and a low stroke volume characterizes the giraffe heart, resulting in typical mammalianleft ventricular wall tensions but lowered cardiac output. Expand
The giraffe kidney tolerates high arterial blood pressure by high renal interstitial pressure and low glomerular filtration rate
TLDR
It is hypothesized that a species‐specific evolutionary adaption in the giraffe kidney allows normal for size renal haemodynamics and glomerular filtration rate (GFR) despite a mean arterial blood pressure double that of other mammals. Expand
Monodontella giraffae Infection in Wild-caught Southern Giraffes (Giraffa camelopardalis giraffa)
TLDR
It is suggested that the nematode M. giraffae may not be an unusual parasite of the giraffe and that it does not necessarily cause detrimental liver disease. Expand
About Myths and Facts in the Cardiovascular System of the Giraffe
Being the tallest living animals, giraffes are endowed with a mean arterial pressure (MAP) twice as high as other mammals, including humans. The high pressure of the giraffe cardiovascular systemExpand
