Document Summary
Pulmonary arterial system relates to the blood flow going from the heart to the lungs (to become oxygenated) via the pulmonary artery. Pressure in the systemic arterial system is stronger that the venous system. If there are any pathogens or microbes, these get picked up by the lymph vessels and are taken to lymphoid tissue bodies & lymph nodes & are cleared out there. Lymphatic vessels (lymphatics), lymph trunks, lymph nodes, lymphoid tissue. Lymph vessels go on to form lymph trunks which then go to lymph nodes (where lymph gets presented for cleaning out) and they then go from there to bigger organs. Therefore, it is only present in mesoderm-derived structures. * avascular & non-lymph structures: ectoderm-derived (epidermis), endoderm-derived (surface epithelium) & articular cartilage (although mesoderm derived it is an exception because it covers bones and is likely to undergo compression & friction)
