ascending aorta – Preliminary part of the aorta, rising from the left ventricle for your distance of close to 5 cm.
basal plate – developmental location in the spinal wire that offers increase on the lateral and anterior horns of grey make a difference.
chordae tendineae – string-like extensions of hard connective tissue that reach in the flaps from the atrioventricular valves on the papillary muscles.
blood–testis barrier – tight junctions involving Sertoli cells that avert bloodborne pathogens from gaining use of afterwards levels of spermatogenesis and forestall the likely for an autoimmune response to haploid sperm.
