ARTICLE III.
Of the influence which the death of the heart exercises upon that of the lungs.
Division of respiratory phenomena, 151
§ I. Inquiry how the action of the lungs is interrupted, when the heart with black blood ceases to act.—In this case the chymical phenomena are first annihilated, 152
§ II. Inquiry how the cessation of action in the heart with red blood interrupts that of the lungs.—In this case death commences by the mechanical phenomena, 153
ARTICLE IV.
Of the influence of the death of the heart upon all the organs.
§ I. Inquiry how the cessation of the functions of the heart with red blood interrupts those of all the organs.—The functions of animal and organic life then cease, partly from the same, and partly from different causes.—Comparison of the different organs with the brain, as to the ingress of blood, motion, &c.—Different considerations on the excitement of the organs by the motion of the blood which enters them, 154
I have passed over in silence the influence of the death of the heart with black blood upon that of the organs, because it is extremely rare that death commences by that.
ARTICLE V.
Of the influence which the death of the heart exercises upon general death.
Series of phenomena in the termination of the two lives.—Permanence of vital properties after death.—Some reflections upon syncope.—It only secondarily affects the brain; its seat is in the heart.—Different proofs of this assertion.—Sometimes in diseases death commences by the heart.—Vacuity of the lungs when this organ is the first affected, 162—168
ARTICLE VI.
Of the influence which the death of the lungs exercises upon that of the heart.
The death of the lungs commences sometimes by the chymical and sometimes by the mechanical phenomena, 169
