The uncinate processes are the small white spurs about halfway along the ribs. The rest of this diagram shows the air sacs and other parts of a bird's respiratory system:1 cervical air sac, 2 clavicular air sac, 3 cranial thoracal air sac, 4 caudal thoracal air sac, 5 abdominal air sac (5' diverticulus into pelvic girdle), 6 lung, 7 trachea
The straight line generated from a double logarithmic scale of metabolic rate in relation to body mass is known as the "mouse-to-elephant curve". [24] These relationships of metabolic rates, times, and internal structure have been explained as, "an elephant is approximately a blown-up gorilla, which is itself a blown-up mouse."
The skin has a huge capacity to accept blood flow resulting in a range of 1ml/100g of skin/min, to 150ml/100g/min. Its metabolic requirements are very low and hence it only requires a very small fraction of the heart's output to maintain its own growth and metabolism.
The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water. The African bush elephant inhabits a variety of habitats such as forests, grasslands, woodlands, wetlands and agricultural land. It is a mixed herbivore feeding mostly on grasses, creepers, herbs, leaves, and bark. The average adult ...

The dwarf elephant P. tiliensis from the Greek island of Tilos is suggested by some authors to have survived as recently as 3,500 years Before Present (around 1500 BC) based on preliminary radiocarbon dating done in the 1970s, which would make it the youngest surviving elephant in Europe, but this has not been thoroughly investigated.
African bush elephant with ears spread in a threat or attentive position and visible blood vessels. Elephant ear flaps, or pinnae, are 1–2 mm (0.039–0.079 in) thick in the middle with a thinner tip and supported by a thicker base.
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
