Title:
High blood pressure

Species:
Giraffe

Description:
The heart of the giraffe beats 56 ± 5 times per minute and its carotid artery pressure is around 200 to 300 mmHg, although in the head, it has a pressure of 100.3 ± 20.9 mmHg. However, when the head is below the heart (which occurs while drinking) the pressure does not increase, since it contains a high density of muscle fibers in the main arteries. In addition, the veins present valves that prevent the return of blood to the heart. The skin of the legs has a thickness of 15 mm and contains a large amount of collagen fibers. Both features act by reducing the vascular edema generated by the venous insufficiency caused by the arterial hypertension presented by the giraffes.
