The circulatory system consists of one heart, five liters of blood, and approximately 96,000 kilometers of blood vessels, responsible for transporting nutrients and waste throughout the body. Water ...

A new imaging breakthrough combines ultrasound and light-based techniques to generate vivid 3D images that show both tissue ...

Leonardo da Vinci’s study of human anatomy combine scientific exploration with expert artistry. Leonardo da Vinci resumes his investigation into human anatomy, merging rigorous scientific exploration ...

Our blood consists of many cell types that develop through different stages from a precursor type -- the blood stem cell. An international research team has now investigated the developmental pathways ...

With each heartbeat, blood courses through your body. Some traverse arteries from the lungs back to the heart, and some navigate through capillaries in the thinnest layers of your eyelid, almost ...

A newly developed imaging method blends ultrasound and photoacoustics to capture both tissue structure and blood-vessel function in 3D.

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

FRANKFURT. Every second, an adult generates around five million new blood cells to replace aging or dying ones, making the blood system a highly regenerative organ. These new blood cells are formed in ...
