  2. Haemodynamic response - Wikipedia

    en.wikipedia.org/wiki/Haemodynamic_response

    In haemodynamics, the body must respond to physical activities, external temperature, and other factors by homeostatically adjusting its blood flow to deliver nutrients such as oxygen and glucose to stressed tissues and allow them to function. Haemodynamic response (HR) allows the rapid delivery of blood to active neuronal tissues. The brain ...

    en.wikipedia.org/wiki/Composition_of_the_human_body

    Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent) Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water , protein , fats (or lipids ), hydroxyapatite (in bones), carbohydrates (such ...

  4. Biological functions of hydrogen sulfide - Wikipedia

    en.wikipedia.org/wiki/Biological_functions_of...

    Animals and humans naturally produce some hydrogen sulfide in their body; researchers have proposed that the gas is used to regulate metabolic activity and body temperature, which would explain the above findings. [18] Two recent studies cast doubt that the effect can be achieved in larger mammals.

  5. Catabolism - Wikipedia

    en.wikipedia.org/wiki/Catabolism

    Catabolism is the breaking-down aspect of metabolism, whereas anabolism is the building-up aspect. Cells use the monomers released from breaking down polymers to either construct new polymer molecules or degrade the monomers further to simple waste products, releasing energy.

  6. Homeostasis - Wikipedia

    en.wikipedia.org/wiki/Homeostasis

    Urinary water loss, when the body water homeostat is intact, is a compensatory water loss, correcting any water excess in the body. However, since the kidneys cannot generate water, the thirst reflex is the all-important second effector mechanism of the body water homeostat, correcting any water deficit in the body.
