Cardiovascular System Flashcard

Front

The cardiovascular system is the first system to function in the embryo because:

Back

It ensures embryonic nutrition

Front

The heart develops from which embryonic germ layer?

Back

Mesoderm

Front

The heart tube is derived from the: Ectoderm, Neural crest, Cardiogenic plate, Notochord, Foregut endoderm

Back

Cardiogenic plate

Front

Which structure is formed when the two endocardial heart tubes fuse? Options: Truncus arteriosus, Pericardial sac, Primitive heart tube, Sinus venosus, Dorsal aorta

Back

Primitive heart tube

Front

The three primary sources of heart development include: Neural tube, septum transversum, and splanchnic mesoderm, Heart tube, myoepicardial mantle, and pericardial sac, Endocardium, pericardial cavity, and sinus venosus, Neural crest, bulbus cordis, and atrioventricular canal, Aortic arches, cardiogenic plate, and myocardium

Back

Heart tube, myoepicardial mantle, and pericardial sac

Front

The process by which the heart tube folds into its characteristic shape is called:

Back

Looping

Front

What is the first chamber to appear during heart development?

Back

Sinus venosus

Front

The last chamber to develop during heart formation is the: Bulbus cordis, Right atrium, Sinus venosus, Left ventricle, Aortic sac

Back

Left ventricle

Front

The atrioventricular canal forms between which two developing structures? Options: Sinus venosus and atrium, Atria and ventricles, Ventricle and bulbus cordis, Truncus arteriosus and atria, Pulmonary trunk and ventricles

Back

Atria and ventricles

Front

The structure responsible for forming the sinus venarum of the right atrium is:

Back

Right horn of the sinus venosus
