How medications are absorbed in the body-

Drug absorption is the process of how drugs get into the bloodstream and travel throughout the body. Although there are many routes of administration the most common and easy-to-use method is oral, such as tablets, capsules, and other forms of pills. These drugs slowly travel to the stomach, dissolve in stomach fluids, pass through the walls of the digestive tract, and enter small blood vessels (known as capillaries). Medication that is inhaled by clients is a direct and efficient route because it goes through the lungs, rapidly absorbed into the capillaries, and sent to the brain without going through the heart. Finally, drugs that are administered via the mucus membrane (mouth or nose), often result in direct absorption into the bloodstream (helpful for children who struggle swallowing pills).

How medications are eliminated from the body-

There are four routes (liver, kidneys, lungs, and skin) through which medications leave the body, a process known as excretion. A majority of the drugs are eliminated through the kidneys as a water soluble compound. These fluids are filtered out of the capillaries held in a chamber known as Bowman’s Capsule, and passed through the bladder. Other pathways for drug excretion include sweat, faeces, bile, and respiration.
