To detect predators by using the large size and flexible positioning of the external ears to channel sound waves into the ear canal.

<h3>What is thermoregulation ?</h3>

Mammals regulate their body temperature carefully and independently of their environment through a process called thermoregulation. A method of maintaining a constant internal temperature necessary for survival is temperature regulation.

  • Poikilothermy and homeothermy are the two main reactions to changing environmental temperatures (TA) that animals display.

  • Progesterone tends to promote heat conservation and higher body temperatures, whilst estradiol tends to increase heat dissipation, and both hormones have an impact on thermoregulation both centrally and peripherally.

Acinar cells

Yes, CCK would be activated in response to a heavy fat and protein meal, which would then drive a pancreatic secretion that is rich in enzymes.

<h3>What do Acinar cells do ?</h3>

Nearly all of the digestive enzymes required for nutrition digestion that are active in the small intestinal lumen are synthesised and secreted by pancreatic acinar cells. To ensure a sufficient supply of digestive enzymes, both synthesis and secretion are tightly controlled over short and long time scales.

  • The exocrine pancreas's role. The centroacinar cells and intercalated duct cells release a biocarbonate-rich buffer solution, whereas the acinar cells create, store, and release digesting enzymes.
