endotherms-heat themselves ectotherms-have to use another source to heat themselves They both must regulate there body temperatue
Homeostasis
The skeletal muscles are responsible for heat generation in the body. This is because they account for 40% of body mass and are required for maintaining body temperature.
Animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestors. Generating internal heat to moderate body temperature, e.g., modern birds and mammals. Warmblooded.
endotherms are mammals like you and me who produce their own body heat and maintain a constant internal condition. Ectotherms are animals whose internal temperature is greatly influenced by its own environment.
Water is the most important substance for maintaining body temperature.
One of the main adaptations that ensures that the body does not lose heat too quickly. It is apart of the Environmental Adaptation as it is how an organism responds to its environment...
yes
Fish are ectothermic, which is commonly referred to as 'cold-blooded'. Their body temperature is dependent on external environmental conditions.

Blood is a vital organ of the body - it delivers nutrients to all cell tissues and removes wastes. It is also important in the immune system, as many immune cells are located in the blood, and in maintaining homeostatis by transferring heat and maintaining fluid balances.
Heat retention is referred to as the energy transferred resulting in a difference in temperature. This allows for heat to be magnified in a specific area.
