Systemic metabolism refers to the biochemical processes that occur throughout the entire organism, rather than in isolated tissues or organs. It encompasses the conversion of nutrients into energy, the synthesis of essential molecules, and the regulation of metabolic pathways in response to physiological needs. This holistic view highlights the interconnectedness of different metabolic processes and their contributions to overall homeostasis and health.

What is the difference between first pass and phase one of drug metabolism?
First pass metabolism refers to the metabolism of a drug that occurs in the liver after it is absorbed from the gastrointestinal tract, before it enters systemic circulation. Phase 1 metabolism is the initial biotransformation of a drug, primarily carried out by enzymes such as cytochrome P450, to make the drug more polar and easier to eliminate from the body.
What is systemic toxicology?
Systemic toxicology is the study of the adverse effects of toxic substances on the body as a whole, including their distribution, metabolism, and elimination. It involves investigating how toxins affect various organ systems and biological processes in the body. This field is crucial for assessing the safety of substances and understanding their potential health risks.
Why is blood carried from the liver before it enters systemic circulation?
Blood is carried from the liver through the hepatic vein before it enters systemic circulation to allow processing and metabolism of nutrients, drugs, and toxins in the liver tissue. This ensures that substances have been properly detoxified or modified by the liver before they are distributed throughout the body.

Is buccal local or systemic?
Buccal administration is considered both local and systemic. When a medication is absorbed through the buccal mucosa in the mouth, it can enter the bloodstream directly (systemic effect) or act locally within the oral cavity.

How does systemic systemic system works?
systemic circulation - BETWEEN the heart and lungs

What will happen to the drug after first pass elimination when taken orallyWill the concentration of the drug decrease?
Depending on the drug, first pass can have a major influence on it's fraction reaching systemic circulation. F = fa x fg x fh Essentially the fraction reaching the systemic circulation or bioavailability (F) is influenced by fa - absorption from intestine, fg = fraction escaping metabolism in the gut, and fh = fraction escaping the first pass (metabolism) by the liver carried via the portal vein. The amount of drug reaching the systemic circulation (bioavailable) can be drastically reduced by first pass. When talking concentration, we can only measure the blood, so the amount reaching could be less.
What is the claimed benefit of Dr Oz's Green Drink?
The claimed benefit of Dr. Oz's Green Drink is it speeds up metabolism, improves energy and deactivates systemic yeast. Another benefit is it stabilizes blood sugar.
Which respiration is the exchange of gases between the blood in the systemic capillaries and tissue fluid?
The respiration that involves the exchange of gases between the blood in the systemic capillaries and tissue fluid is known as internal respiration. During this process, oxygen diffuses from the blood into the tissue cells, while carbon dioxide diffuses from the cells into the blood. This exchange is crucial for cellular metabolism and energy production.
What are the two types of circulation of blood in the body?
Pulmonary and systemic
What is the sum of all the chemical processes that take place in an organism?
is called metabolism .
How do systemic pesticides work to kill pests?
Systemic pesticides are absorbed by plants and distributed throughout their tissues, including leaves, stems, and roots. When pests feed on these parts of the plant, they ingest the pesticide, which disrupts vital processes within their bodies, such as nervous system function or metabolism. This leads to the death of the pests over time, effectively controlling infestations while minimizing direct exposure to beneficial organisms.
