Lazaro Spartier

On February 11, 1799, the famous Italian naturalist, physiologist and experimental physiologist Lazaro Spartier passed away at the age of 70.

character brief introduction

Lazaro Sparatier was born in the town of Scandiano, Italy. His father was a famous lawyer and his mother came from a wealthy family. He had in-depth research on animal blood circulation, animal digestive physiology, fertilization, etc. His bat experiments provided the theoretical basis for the study of "ultrasound". In addition, he was also one of the founders of volcanology. He died of anuria on February 11, 1799, at the age of 70. Sparatier dedicated his life and part of his body to the cause of science. According to his will, his ailing bladder was dedicated to the Natural Museum of Pavia.

When Spaltier was young, under the guidance of his cousin, Spaltier developed a strong interest in natural sciences, so he transferred to natural sciences and obtained a doctorate in 1753. Shortly thereafter, the church appointed him priest and became a priest in 1760. The church's financial support ensured the smooth progress of his scientific career.

research results

In 1765, Spalatier began research on animal regeneration. After thousands of experiments, it has been discovered that the regenerative ability of animals is stronger than that of higher animals, young animals are stronger than adult animals, and body surface tissues are stronger than internal organs. In addition, he also used snails to transplant the head of a human body and was successful. Successfully unveiled the mystery of bat flight at night. He collected his research results in two books,"A Brief Comment on Animal Regeneration" and "Experimental Results on the Head Regeneration of Land Snail".

Sparatier also conducted a systematic study of the circulatory system of animals, proposing that in addition to the pressure generated by the heart, the beating of the arteries also has the elastic effect of the blood vessel wall. In 1768, he published "On the Movement of the Heart", summarizing the results in this regard.

In 1777, Sparatier began to study the digestive physiology of animals. In 1783, he first introduced the term "digestive juices" through experiments, believing that digestive juices contain certain chemical components that can decompose food. The so-called digestion is the process of digestive juices decomposing food.

From 1771 to 1780, Spalatier also conducted research on fertilization issues. At first, Spalatier was an oogenist, believing that eggs contained extremely shrunk individuals of the organism. Later, through experiments, Sparratier invented an artificial insemination method.
