A comprehensive overview of the respiratory system, covering its key components, functions, and processes. It delves into the structure and roles of the trachea, lungs, pharynx, bronchi, larynx, alveoli, diaphragm, and epiglottis, as well as the mechanisms of inhalation and exhalation. The document also explores the right and left lungs, their lobes, and the overall function of the respiratory system in taking in oxygen and expelling carbon dioxide. This resource offers a detailed understanding of the respiratory system, making it a valuable study material for students in various fields, including biology, medicine, and health sciences.

THE RESPIRATORY SYSTEM, THE RESPIRATORY SYSTEM QUESTION AND ANSWER 2024 GRADED A+ UPGRADE Trachea ANSWER = It is also known as windpipe, it filters the air we inhale and branches into the bronchi. Lungs ANSWER = The main organ of the respiratory system. Pharynx ANSWER = Tube that connects the mouth to the larynx and esophagus. Bronchi ANSWER = Tube that connects the trachea to the lungs. Larynx ANSWER = commonly called the voice box, and a connection between the pharynx and trachea Aveoli ANSWER = It is the tiny sac like structure present in the lungs which the gaseous exchange takes place. Diaphragm ANSWER = Breathing begins with a dome-shaped muscle located at the bottom of the lungs. Epiglottis ANSWER = It is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box. Respiratory system ANSWER = This system has a primary organ which is lungs, the function is to take in oxygen and expel carbon dioxide as we breathe.
Right Lung ANSWER = It has 3 lobes: superior, middle, and inferior and it is the larger of the two lungs. Left Lung ANSWER = It has 2 lobes: superior and inferior and it is the smallest of the two lungs. Inhale ANSWER = To breathe in, diaphragm flattens Exhale ANSWER = To breathe out, diaphragm relaxes Inspiration ANSWER = The diaphragm contracts causing the lungs to stretch. This decreases the pressure inside causing air to rush into the lungs, balancing the air pressure and inflating the alveoli. Expiration ANSWER = The medula obongata stops sending signals to the intercostal muscles and diaphragm so they stop contracting. This decreases the volume in the lungs so the air pressure increases. This forces carbon dioxide out of the lungs and they deflate.
