@gethelpwithproctoredexam: The liver is the human body's premier internal powerhouse, acting as a high-tech filtration system and chemical plant all in one. Tucked safely in the upper right abdomen, this reddish-brown organ weighs roughly 1.5 kg and is divided into distinct right and left lobes. It operates at a cellular level through units called lobules, which are supplied with nutrient-rich blood via the portal vein and oxygen via the hepatic artery. Its biological workload is staggering: it detoxifies the blood of harmful substances, metabolizes essential macronutrients (carbs, proteins, and fats), and produces bile for digestion. Beyond processing, it serves as a vital warehouse for glycogen, iron, and vitamins. By regulating blood sugar and supporting immune function, the liver maintains the body’s internal balance. However, its efficiency can be compromised by conditions like fatty liver, hepatitis, or cirrhosis, making it essential to protect this silent hero that keeps you running every single day. #student #nursingnotes #study #nursingstudent #nurse
