Gaseous Exchange is a crucial topic in FSC Biology and important for MDCAT and entry test preparation. It is the process by which organisms take in oxygen (O₂) for respiration and release carbon dioxide (CO₂) as a waste product. In humans, gaseous exchange occurs in the alveoli of the lungs, where oxygen diffuses into the blood and carbon dioxide diffuses out. In plants, it takes place through stomata, lenticels, and cell membranes. Efficient gaseous exchange is essential for cellular respiration, energy production, and maintaining homeostasis. Understanding the mechanisms, structures, and adaptations involved in gaseous exchange is vital for FSC board exams and MDCAT entry test preparation. PLS Academy provides clear concept-based explanations, diagrams, and practice MCQs to help students excel in this topic.
