"Natural calamities and the human body"

  • Natural calamities are associated with blood clots and blood supply issues.
  • Touching natural calamities can cause heat and noise.
  • Waterlogging occurs in both natural calamities.
  • An air filter is used to prevent moisture and warmth before entering.
  • The esophagus divides into two tubes, the food pipe and the windpipe.
  • The epiglottis covers the opening to the windpipe while eating.
  • The anterior end of the windpipe is where the vocal cords are located.
  • The vocal cords are essential for producing voice.
  • Air enters the windpipe and passes through the vocal cords to produce sound.
  • The larynx is crucial for the passage of air and sound production.

Vocal cords vibrate for sound production.

  • Tractors in the body start fluttering when air passes through them, causing vibrational sound production.
  • Vibration is essential for the vocal cords to produce sound, enabling speech.
  • The vocal cords vibrate when air passes through them, creating sound.
  • Testosterone release during puberty thickens vocal cords in boys, resulting in a deeper voice.
  • The incomplete rings of cartilage in the trachea support the walls and prevent collapse.
  • The contraction and relaxation of the trachea's muscular tube affect voice production.
  • The trachea's internal walls are lined with stratified columnar epithelium.
  • Blood vessels and goblet cells pass through the trachea's walls, aiding in mucus production.
  • Mucus in the trachea traps dirt, dust particles, and bacteria, aiding in respiratory health.
  • The mucus in the trachea serves to trap and remove impurities from the airways.

Mucus traps dirt, aids lung health.

  • Mucus in the body traps dirt, dust particles, pollen grains, bacteria, allergens, and pathogens to prevent infections in the lungs.
  • The mucus, once filled with dirt, needs to be expelled to remove the trapped contaminants.
  • Rhythmic movements help in expelling the dirt-trapped mucus from the body.
  • The mucus moves in one direction, from the mouth upwards, to facilitate the removal of trapped dirt.
  • The mucus, after being expelled, helps in maintaining lung health by preventing infections.
  • The body's thoracic cavity is divided into three parts: Direct Endowment Health, Dormitory Held for Research and Development, and Smooth.
  • The thoracic cavity contains the trachea and is further divided into smaller branches for efficient functioning.
  • The primary bronchi branch into secondary bronchi, then tertiary bronchi, and finally into terminal bronchioles.
  • The terminal bronchioles are the smallest branches that facilitate the exchange of gases in the lungs.
  • The terminal bronchioles are crucial for maintaining lung health and are the final part of the respiratory system before the alveoli.
