What to know for exams
- The Pulmonary trunk arises from the right ventricle and divides into the right and left pulmonary arteries.
- The Pulmonary trunk carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
- The Pulmonary trunk is located anterior to the ascending aorta and posterior to the left atrium.
It belongs to the organs layer. Learn its location, relations, and the structures it works with.
Clinical relevance
The Pulmonary trunk is located anterior to the ascending aorta and posterior to the left atrium.
Link the pulmonary trunk to its blood supply, innervation and relations. That is how exam questions usually test it.
