  2. QUESTION:
    What process is responsible for moving food along the esophagus and intestines?

    • ANSWER:
      Peristalsis

      Check out the Wikipedia entry, which begins ...

      "Peristalsis is the rhythmic contraction of smooth muscles to propel contents through the digestive tract. The word is derived from New Latin and comes from the Greek peristaltikos, peristaltic, from peristellein, "to wrap around," and stellein, "to place."

      "In much of the gastrointestinal tract, smooth muscles contract in sequence to produce a peristaltic wave which forces a ball of food (called a bolus while in the esophagus and gastrointestinal tract and chyme in the stomach) along the gastrointestinal tract. Peristaltic movement is initiated by circular smooth muscles contracting behind the chewed material to prevent it from moving back into the mouth, followed by a contraction of longitudinal smooth muscles which pushes the digested food forward."

  3. QUESTION:
    What are the components of the respiratory system?
    And what are all the chemical processes?
    What is the function of the diaphragm?

    • ANSWER:
      Larynx

      Known colloquially as the ‘Voice Box’, the larynx contains vocal cords that vibrate when sound is made.
      The vocal cords are also known as the ‘vocal folds’.

      Forming the sounds that comprise speech.

      Pharynx

      The Naso-Pharynx is the junction of the nasal passage and the buccal cavity.

      A muscular tube lined with mucous membrane, that extends from the beginning of the oesophagus (gullet) up to the base of the skull.
      It is divided into the:

      Nasopharynx

      Oropharynx

      Laryngopharynx

      The pharynx acts as a passageway for food from the mouth to the oesophagus, and as an air passage from the nasal cavity and mouth to the larynx. It also acts as a resonating chamber for the sounds produced in the larynx.

      Trachea

      The windpipe, the part of the air-passage between the larynx and the main bronchi (i.e. from just below the Adam’s Apple, passing behind the notch of the sternum). This is kept open by a ‘C’-shaped ring of cartilage – the hyoid bone.

      The upper part of the trachea lies just below the skin, except where the thyroid gland is wrapped around it.

      The lower part of the trachea divides into two bronchi (one for each lung). These lead to the upper and lower bronchioles, and eventually the alveolar ducts.

      Connects the external respiratory organs (nares and buccal cavities) with the lungs.

      Bronchi

      The bronchi are air passages beyond the trachea, which have cartilage and mucus glands in their walls.
      The trachea divides into two main bronchci, which divide successively into five lobar bronchi, 20 segmental bronchi, and two or three further divisions

      Components essential for external respiration.

      Broncioles

      Bronchioles are subdivisions of the bronchial tree that do not contain cartilage or mucus glands in their walls.
      They (bronchioles) open from the 5th or 6th generation of bronchi and extend for up to 20 more generations before reaching the terminal bronchioles. Each terminal bronchiole divides into a number of respiratory bronchioles, from which the aveoli open.

      Components essential for external respiration.
      Each terminal bronchiole conducts air to an acinus in the lung.

      Alveoli

      An alveolus in the lung is a blind-ended air sac of microscopic size.
      About 30 alveoli open out of each alveolar duct, which leads from a respiratory bronchiole. The alveolar walls, which separate alveoli contain capillaries. The alveoli are lined by a single layer of pneumocytes, which thus form a very thin layer between air and blood so that exchange of oxygen and carbon dioxide is normally rapid and complete.
      Children are born with about 200 million alveoli. The adult number of about 300 million is reached around the age of eight years.

      Components essential for external respiration.

      Diaphragm

      The diaphragm is a thin musculomembranous dome-shaped muscle that separates the thoracic and abdominal cavities.
      It is attached to the lower ribs at each side, and to the breast bone and the backbone at the front and back.
      It bulges upwards against the heart and lungs, arching over the stomach, liver, and spleen.
      There are openings in the diaphragm through which the oesaphagus, blood vessels, and nerves pass.

      The diaphragm plays an important part in breathing. It contracts with each inspiration, becoming flattened downwards and increasing the volume of the thoracic cavity. With each expiration the diaphragm relaxes and is restored to its dome shape.
