## Summary
Marcello Malpighi was an Italian physician, anatomist, and biologist (1628–1694) who made foundational contributions to microscopy and the understanding of human and plant anatomy. He is best known for discovering the capillary system, linking arteries and veins, and for pioneering microscopic studies of biological tissues, which laid the groundwork for modern histology and physiology.

## Biography
- **Born**: March 10, 1628 (Crevalcore, Papal States)
- **Died**: November 29, 1694 (Rome, Papal States)
- **Nationality**: Italian (citizen of the Papal States)
- **Education**:
  - University of Bologna (medicine)
  - University of Pisa (studied under Giovanni Alfonso Borelli)
- **Known for**: Discovering the capillary system, advancing microscopic anatomy, and contributing to plant physiology
- **Employer(s)**:
  - University of Bologna (professor of medicine)
  - University of Pisa (professor of theoretical medicine)
- **Field(s)**: Anatomy, physiology, microscopy, botany, entomology

## Contributions
Marcello Malpighi revolutionized the study of anatomy and physiology through his pioneering use of the microscope. His key discoveries include:
- **Capillary System (1661)**: Demonstrated the existence of capillaries, proving William Harvey’s theory of blood circulation by showing how arteries and veins connect.
- **Lung Structure (1661)**: Described the alveolar structure of the lungs, explaining gas exchange.
- **Skin Anatomy**: Identified layers of the skin, including the Malpighian layer (stratum germinativum).
- **Plant Anatomy**: Studied plant tissues, including the structure of leaves and stems, contributing to early botany.
- **Silkworm Studies**: Conducted microscopic research on silkworm anatomy, advancing entomology.
- **Kidney Structure**: Described the renal pyramids and Malpighian corpuscles (renal corpuscles), critical to understanding kidney function.

His works, such as *De Pulmonibus* (1661) and *De Viscerum Structura* (1666), established microscopy as essential to biological research.

## FAQs
**What did Marcello Malpighi discover?**
Malpighi discovered the capillary system, proving how blood circulates between arteries and veins. He also described the alveolar structure of lungs, skin layers, and kidney components like the Malpighian corpuscles.

**Where did Malpighi study and work?**
He studied at the University of Bologna and the University of Pisa, later teaching at both institutions. He also worked in Rome under papal patronage.

**What is the Malpighian corpuscle?**
It refers to the renal corpuscle in the kidney, which Malpighi described, and also to a disambiguation page for his namesake structures in biology.

**How did Malpighi influence modern medicine?**
His microscopic studies laid the foundation for histology and physiology, enabling later advances in cellular biology and medical diagnostics.

**What honors or recognitions did Malpighi receive?**
He was elected to the Royal Society (1669) and the Arcadian Academy (1690), and an asteroid (11121 Malpighi) and a glacier (Malpighi Glacier) were named after him.

## Why They Matter
Malpighi’s work bridged macroscopic anatomy and microscopic biology, proving that complex physiological systems could be understood through detailed observation. His discovery of capillaries confirmed Harvey’s circulation theory, while his studies of lungs, skin, and kidneys advanced medical knowledge. By applying microscopy to biology, he pioneered a methodology that became central to modern science. His influence extends to botany, entomology, and comparative anatomy, making him a foundational figure in the scientific revolution.

## Notable For
- Discovering the capillary system (1661), resolving the circulation debate.
- First to describe lung alveoli and skin layers microscopically.
- Identifying renal pyramids and Malpighian corpuscles in kidney anatomy.
- Pioneering microscopic studies of plants and insects.
- Member of the Royal Society (1669) and Arcadian Academy (1690).
- Namesake of asteroid 11121 Malpighi and Malpighi Glacier in Antarctica.
- Author of *De Pulmonibus* (1661) and *De Viscerum Structura* (1666).

## Body

### Early Life and Education
Marcello Malpighi was born on March 10, 1628, in Crevalcore, part of the Papal States. He studied medicine at the University of Bologna, one of Europe’s oldest universities, and later at the University of Pisa, where he worked under Giovanni Alfonso Borelli, a prominent mathematician and physiologist.

### Career and Research
Malpighi’s career spanned academia and research:
- **University of Bologna**: Served as a professor of medicine, where he conducted much of his microscopic research.
- **University of Pisa**: Taught theoretical medicine, collaborating with Borelli on physiological studies.
- **Papal Patronage**: Later moved to Rome, where he worked under papal support, continuing his anatomical investigations.

His research focused on applying the microscope to biological tissues, a novel approach at the time. Key publications include:
- *De Pulmonibus* (1661): Described the lung’s alveolar structure.
- *De Viscerum Structura* (1666): Detailed the anatomy of organs like the liver and spleen.

### Major Discoveries
- **Capillary System**: In 1661, Malpighi observed capillaries in frog lungs, proving Harvey’s theory of blood circulation.
- **Skin Anatomy**: Identified the Malpighian layer (stratum germinativum), crucial for understanding skin regeneration.
- **Kidney Structure**: Described the renal pyramids and Malpighian corpuscles, foundational to nephrology.
- **Plant and Insect Studies**: Applied microscopy to botany and entomology, studying silkworms and plant tissues.

### Legacy and Influence
Malpighi’s work established microscopy as a cornerstone of biological research. His discoveries influenced later scientists, including:
- **Anatomy**: His detailed descriptions of tissues advanced histology.
- **Physiology**: His studies of circulation and respiration shaped modern understanding.
- **Botany and Entomology**: His plant and insect research contributed to these fields.

### Honors and Namesakes
- **Royal Society**: Elected in 1669 for his contributions to science.
- **Arcadian Academy**: Joined in 1690, recognizing his intellectual achievements.
- **Asteroid 11121 Malpighi**: Named in his honor.
- **Malpighi Glacier**: An Antarctic glacier bearing his name.
- **Malpighiaceae**: A plant family named after him.

### Death and Burial
Malpighi died on November 29, 1694, in Rome. He is buried in the Church of the Saints Gregory and Siro in Bologna, Italy.

### Impact on Modern Science
Malpighi’s integration of microscopy into biology transformed how scientists study life. His methods and discoveries remain foundational in anatomy, physiology, and related fields, cementing his legacy as a pioneer of the scientific revolution.
