Small organs have high surface area:volume ratio.So they are active than large organs.
Tools such as positron emission tomography (PET) scans and fluorodeoxyglucose (FDG) tracer can be useful for viewing metabolic activity in the body. These methods involve measuring the uptake of glucose, a marker of metabolic activity, in different tissues. PET scans can provide valuable information about the functioning of organs and tissues in the body.
The pituitary and thyroid glands are typically larger in humans compared to cats due to differences in hormone regulation and metabolic rates. Human adrenal glands are also relatively larger as they are essential for stress response and regulation in humans.
No. Why should they? You've got tiny little organs like the parathyroid glands, they obviously don't need as much "power" to work as the brain or the muscles, and carbon dioxide production is more or less directly related to how much sugar the organ "burns".
Organs such as the liver, brain, and heart contribute the most to resting metabolic needs due to their high metabolic activity. These organs require a significant amount of energy to perform essential functions even when the body is at rest. Additionally, muscle tissue also plays a role in resting metabolism as it accounts for a higher percentage of overall body mass.
The kidneys, liver, and lungs are the primary organs that help eliminate metabolic waste products from the body. The kidneys filter waste products from the blood to produce urine, the liver processes and detoxifies metabolic waste, and the lungs excrete waste gases through respiration.

The metabolic rate does change with the development of an animal from a zygote to adult because of the development of the organs. As growth occurs the organs fully develop.

Nutrient metabolism involves various pathways that occur in different organs and cells. For example, carbohydrate metabolism primarily occurs in the liver, muscle, and adipose tissue, while lipid metabolism happens mainly in adipose tissue and the liver. Protein metabolism takes place in the liver and various tissues throughout the body. These pathways are interconnected, with organs like the liver playing a central role in coordinating the metabolism of different nutrients.

Tissues such as adipose (fat) tissue produce relatively little internal heat compared to active muscle tissue. Additionally, organs like the skin, which primarily serve as a barrier and regulator of temperature rather than a heat producer, also generate minimal internal heat. Overall, areas with lower metabolic activity, such as the brain at rest, contribute less to the body's heat production compared to highly active tissues.
When parasympathetic activity increases, it promotes a state of rest and relaxation in the body, often referred to as the "rest and digest" response. This leads to a decrease in heart rate, enhanced digestion, and increased glandular activity. Additionally, blood flow may be redirected towards the digestive organs, facilitating processes such as nutrient absorption and metabolic regulation. Overall, heightened parasympathetic activity supports recovery and energy conservation.
