A developing embryo has a complete endocardial cushion defect. The foetus develops to full-term and is born at 39 weeks gestation. 1) Describe which septum are missing in this newborn (2 marks); 2) Compare and contrast the blood flow in the developing foetus (1 mark), to that in the newborn, including oxygenation and shunting of blood (1 mark); 3) Describe which side of the heart will have increased blood volume, and how this increased blood volume will impact the heart wall thickness over time (1 mark). Hint: Think about which side of the heart will end up with more blood (i.e. blood volume) as the heart beats, and identify how this increased blood volume will impact the heart tissue growth (i.e. hypertrophy etc.) Key words: Atria, Ventricle, shunt, hypertrophy Use dot points to answer this question *Use dot points 1) Describe which septum are missing in this newborn (2 marks); Interatrial septum 2) Compare and contrast the blood flow in the developing foetus (1 mark), to that in the newborn, including oxygenation and shunting o blood (1 mark); 3) Describe which side of the heart will have increased blood volume, and how this increased blood volume will impact the heart wall thickness over time (1 mark).
Ans :- septum which is missing is interarterial septum . Blod flow in affected child will left to right shunting od blood and it will move from left atrium to ri
