Final answer:
Jessica would discuss the processes of how drugs are transported within the body to the cells they target, including the role of transport proteins, cardiovascular system, and pharmacokinetics involved in drug transport and elimination.
Step-by-step explanation:
Jessica's lecture on "The Transport of Drugs from Bloodstream to Site of Action" would cover the intricate processes involved in how drugs move within the body to reach their intended targets. One of the key mechanisms involves molecules attached to transport proteins, which facilitate the delivery of drugs through the bloodstream to the cells that need them. This is crucial for pharmaceutical substances to exert their therapeutic effects.
In discussing the cardiovascular system, Jessica would likely explain its role in transporting substances such as drugs throughout the body. The lecture could also delve into the properties of drugs and how they influence their passage across various barriers within the body, such as cell membranes, metabolic enzymes, and efflux transporters. Factors like drug absorption in the gastrointestinal (GI) tract, whether through passive diffusion or active transport, and how the body eliminates drugs via processes like glomerular filtration and tubular secretion could also be covered.
Moreover, Jessica would address considerations such as the pharmacokinetics involved in drug discovery and development, including drug elimination. Important considerations for choosing the route of administration, such as oral versus parenteral (e.g., intravenous or intramuscular injection), based on factors like absorption and plasma levels will likely be part of the discussion as well.
