Embryology 3 Flashcards
what is the bronchial tree?
it is a branching system of bronchi and bronchioles, conducting air from the windpipe into the lungs
what is the function of the bronchial tree?
to distribute air to the lungs
what is the function of the trachea?
to distribute air to the lungs
what is the alveoli responsible for?
the primary function of the lungs, exchanging carbon dioxide and oxygen
what is the trachea and the 2 primary bronchi referred to together?
the bronchial tree
what lies at the end of the bronchial tree?
the alveolar ducts, the alveolar sacs and the alveoli
how are alveolar sacs formed?
they are formed by a group or cluster of alveoli, it is where the alveoli communicate
what occurs in the alveolar sacs?
exchange of oxygen and carbon dioxide
what are thin walled and rich in capillaries?
alveolar sacs
what is the diaphragm?
it is a dome-shaped sheet of muscle and tendon that serves as the main muscle or respiration and plays a vital role in the breathing process
what serves as an important anatomical landmark that separates the thorax from the abdomen?
the diaphragm
how is the diaphragm formed?
the septum transversum gives rise to parts of the thoracic diaphragm
what is the septum transversum?
it is a thick mass of cranial mesenchyme, formed in the embryo
what are abnormalities of the respiratory system?
abnormalities of lung development
abnormalities of the upper respiratory tract
abnormalities of the supporting musculoskeletal system
abnormalities of the vascular and neural system
