Question : ok i actually feel like crap because i am sick. i regret my other question now lol. so i took my temperature and it said 36.8 degrees celsius. is that high or normal because i dont know what temperature your body is meant to be.
Answer : The normal range of human body temperature varies due to an individuals metabolism rate, the higher (faster) it is the higher the normal body temperature or the slower the metabolic rate the lower the normal body temperature. Other factors that might affect the body temperature of an individual may be the time of day or the part of the body in which the temperature is measured at. The body temperature is lower in the morning, due to the rest the body received, and higher at night after a day of muscular activity and after food intake.
Where you take the temperature may also be a factor. Oral temperatures, probably the most common use of temperature taking, is at 37.0 C. Axillary temperatures, external such as the armpit, is usually at 97.6 F (36.4 C). Mind you, it s the most long and inaccurate of all temperature measuring methods. Rectal temperatures fall at 99.6 F (37.6 C) and this is the most accurate way of taking temperatures, being because it is internal.

Question : I can't find this answer anywhere!
Answer : SIMILARITIES:
For both you need an ideal respiratory surface, whether it be internal (like human alveoli) or external (like skin of earthworm):
The respiratory surface for both must be:
3. close to a supply of oxygen
4. close to a blood or transport system.
External respiration, commonly known as breathing, is the exchange of oxygen and carbon dioxide between an animal and its environment. Most animals use specialized organs or organ systems, such as lungs, trachea, or gills, for external respiration.
Internal respiration is the exchange of oxygen and carbon dioxide between blood and cells in different tissues of an animal's body. Internal respiration occurs in animals with a circulation system. Animals with gills or lungs take up oxygen and transport oxygen-rich blood throughout the body; they transport carbon dioxide-rich blood from the body back into the respiratory organs where it is expelled. The oxygen-rich blood and carbon dioxide-rich b..
