Human Body /Diaphragm Song

The video tutorial provides an in-depth look at the diaphragm, a dome-shaped muscle crucial for respiration. It explains the diaphragm's anatomical position, separating the chest from the abdomen, and its structure, composed of muscle and tendon. The tutorial details the diaphragm's function in breathing, highlighting how it flattens during inhalation and returns to a dome shape during exhalation. It also covers the diaphragm's attachment points, including the lumbar vertebrae and sternum, and mentions alternative names like the thoracic diaphragm. Key structures passing through the diaphragm, such as the vena cava, aorta, and esophagus, are also discussed.
