Respiratory tract

The lecture will introduce the development of the respiratory system and associated structures. The lecture will not cover adult anatomy, physiology of gas exchange and red blood cell function and cardiovascular development.

The respiratory system does not carry out its physiological function (of gas exchange) until after birth, though the respiratory tract, diaphragm and lungs do begin to form early in embryonic development and continue through fetal development, only functionally maturing just before birth.

The respiratory tract is divided anatomically into 2 main parts:

  1. upper respiratory tract - consisting of the nose, nasal cavity and the pharynx.
  2. lower respiratory tract - consisting of the larynx, trachea, bronchi and the lungs.

The respiratory "system" usually includes descriptions of not only the functional development of the lungs, but also related musculoskeletal (diaphragm) and vascular (pulmonary) development.

Aims

adult lungs

To understand the prenatal and postnatal developmental anatomy of human respiratory organs.

Key Concepts

  1. Embryonic origin of respiratory components (tract, lungs, diaphragm, muscles)
  2. Key stages in respiratory development.
  3. Time course of respiratory development.
  4. Respiration at birth.
  5. Postnatal development of respiration.
  6. Developmental abnormalities.


lung structure
alveoli and blood vessels
