Respiration is the process in which inhalation of oxygen and exhalation of carbon dioxide occurs with the help of contraction and relaxation of muscles. Respiratory muscles are responsible for the inhalation and the exhalation process by the expansion and contraction of the thoracic cavity. The three groups of respiratory muscles are:- diaphragm, rib cage muscles and the abdominal muscles. These groups act on the wall of the chest and its compartments (the lung-apposed rib cage, the diaphragm-apposed rib cage, and the abdomen). The strength of the diaphragm is reflected by the MIP and other inspiratory muscles, while the strength of the abdominal muscles is reflected by the MEP and other expiratory muscles. Inspiratory muscle strength is the maximal sniff nasal inspiratory pressure. Lungs are a part of the breathing system, a collection of organs and tissues that works collectively that will help us to breathe. The breathing system's most important activity is to transport clean air into your frame at the same time as doing away with waste gases. Every cell needs oxygen so one can live. The air we breathe is made up of oxygen and various gases. Once with the lungs, the oxygen is moved to the blood and transported in the frame. In every cell in the body, oxygen is exchanged for carbon dioxide. The individual's bloodstream then includes this waste gas lower back to the lungs wherein it's far eliminated from the bloodstream after which exhaled. The lungs and respiration regularly go through this essential process, known as gas exchange.In addition to gas exchange, your respiration gadget plays different roles essential to breathing. These include:- Bringing air to the right frame temperature and moisturizing it to the proper humidity level.Protecting the body frame from dangerous substances. This is achieved with the aid of using coughing, sneezing, filtering, or swallowing them. Right lung consists of 3 LOBES. Each lobe is a balloon filled with sponge-like tissue. Air moves in and out via an opening which is a branch of the bronchial tube whereas left lung is divided into 2 LOBES. The anterior edge of the lung corresponds to the pleural reflex and creates a cardiac notch in the left lung. The heart notch is a concavity in the lung that forms to face the heart.Answer:- Left lung contains cardiac notch.
