Warm-blooded vs. Cold-Blooded Animals
Most animals can be classified as either warm-blooded or cold-blooded. For example, all mammals and birds are warm-blooded, while all reptiles, amphibians, insects and fish are cold-blooded. As the owner of a leopard gecko, which is cold blooded, and a dog, which is warm-blooded, I chose this topic for my essay because I wanted to understand exactly what it means to be warm-blooded or cold-blooded, and how these creatures differ.
Basically, the temperature of an animal's blood is directly related to its body temperature. Warm-blooded creatures keep the inside of their bodies at a consistent temperature by generating their own body heat when they are in a cold environment, and cooling their body heat down when they are in a hot place. In order to create heat, warm-blooded animals transform all consumed food into energy. In comparison to cold-blooded animals, warm-blooded animals must eat a lot of food, in order to maintain a consistent body temperature. While they convert some of the food into body mass, the majority of the food is used to maintain their body temperature.
Warm-blooded animals have different ways of changing their body temperatures. They often sweat or pant to give off heat through water evaporation, or stay in cool areas or the water when they need to cool down. Warm-blooded mammals, with the exception of whales, have sweat...
Dinosaurs: Warm-Blooded? There is presently much controversy regarding the issue of dinosaurs, as the fact that experts have access to a limited amount of resources concerning this matter makes it difficult for them to express certainties concerning this particular animal reign. Even with the fact that there are presently no living dinosaurs to be dissected, scientists have come up with a series of theories based on how dinosaurs behaved. In spite
The picture to the left depicts the various elements that are responsible for thermoregulation in human skin. The illustrations shows the various layers of skin along with the veins, arteries and capillaries of the circulatory system that assist in insuring that the thermoregulatory system works properly. The sweat glands are responsible for selectively removing materials from the blood the sweat glands then concentrates or alters these toxins, and secretes them
Animals Thermoregulation There are a number of physical responses that occur in the a mammal's body when it is exposed to heat. It is important to not only understand what thermoregulation is, but the physiological and/or anatomical thermoregulatory responses that allow sustained exercise in horses. Understanding Thermoregulation Thermoregulation is the control of body temperature within certain limits even when the surrounding temperature is very different. This enables the body to function effectively and is
' That set point can shift, depending upon environmental influences. For example, if someone is infected, a fever can actually help his or her body survive the disease, as certain kinds of bacteria grow less vigorously at high temperatures. Cytokines attacking the intruders send signals to the hypothalamus to release prostaglandins to 'give' the person a fever. Even if the person moves to a cold room, the fever will persist,
Cellular Respiration Give the overall general reaction for cellular respiration. State what eukaryotic cell organelle is involved. Cellular respiration is the process by which cells convert biochemical energy from nutrients into adenosine triphosphate (ATP). In general, sugar is burned off, or oxidized, into CO2 and H2O. The overall formula is C6H12O6 + 6O2 -> 6CO2 + 6H2O + ~38 ATP (heat). Mitochondria are the eukaryotic cell organelle involved in this process. It
Cold War and Film Generally speaking, the Cold War has been depicted as an era of spy games and paranoia in popular films from the 1960s to the present day, but the reality of the era was much more complex. The Cold War was a period of military and political tension from 1947 to 1991, or from the end of WW2 to the collapse of the Soviet Union, in which
