  What is Plant Anatomy? Plant anatomy is the study of internal structure and organization of tissues in plants. It helps in understanding: Functional adaptation Transport system Growth patterns Tissue Organization in Flowering Plants Flowering plants have three major tissue systems :  Epidermal Tissue System Components: Epidermis Single layer of compact cells No intercellular spaces Covered by cuticle (except roots) Cuticle Made of cutin Prevents water loss Stomata Present mainly on leaves Composed of guard cells Regulate: Gas exchange Transpiration Root hairs Extensions of epidermal cells Increase surface area for absorption Trichomes (in stem) Hair-like structures Protection + reduce transpiration  Functions: Protection Water conservation Gas exchange 🌿 B. Ground Tissue System  Types of Ground Tissue: 1. Parenchyma Living cells, thin cell wall Large vacuole Functions: Storage Photosynthesis ( chlorenchyma ) Air storage ( aerenchyma ) 2. Collenchyma Living cell...

 Coronary artery disease (CAD) is a condition that occurs when the blood vessels (coronary arteries) that supply oxygen-rich blood to the heart muscle become narrow or blocked due to the accumulation of plaque or fatty deposits, leading to reduced blood flow and oxygen supply to the heart. Causes Atherosclerosis: This is a process where plaque, made up of cholesterol, calcium, and other substances, builds up on the walls of the coronary arteries over time, narrowing them and reducing blood flow to the heart. This can be caused by a variety of factors, including high cholesterol levels, high blood pressure, smoking, diabetes, and obesity. High blood pressure: When blood pressure is consistently high, it can cause damage to the inner lining of the arteries, making them more vulnerable to the accumulation of plaque. High blood pressure can also cause the heart to work harder to pump blood, leading to an increased risk of CAD. High cholesterol levels : High levels of LDL or "bad...
