#vascular system

When biomedical researchers need to test their latest ideas, they often turn to engineered human tissue that mimics the responses in our own bodies. It's become an important intermediary step before human clinical trials. One limiting factor: The cells need blood circulation to survive, and achieving that can be difficult in three-dimensional cell structures. Without proper vascular systems—even primitive ones—engineered tissue faces restricted size and functionality, even developing necrotic regions of dead cells.

In the 1920s, scientists noted this increasing plant complexity in the fossil record but were not able to pinpoint the reason land plants adapted to drier climates.

How the early land plants were able to adapt to new habitats and move beyond their original moist, boggy environments. These plants were small, usually no more than a few centimeters tall, and were found near streams and ponds. Land plants are now more resistant to drought, allowing them to thrive in new, drier environments.

However, about 400 million years ago, they developed vascular systems that allowed them to extract water more efficiently from the soil and use it for photosynthesis, a change that had a significant impact on the Earth’s atmosphere and ecosystems.

Cardiovascular Anatomy

*

Hello Everyone!

I’m currently in my study week for end of semester exams. I decided to target one of my difficult areas for anatomy which is labeling the different veins and arteries of the body. I’m really proud of how this page turned out I think it’s really pretty and hopefully having to actually draw out the vessels and label them will help me remember them in the exam. I just realised that I forgot to label the hepatic portal vein in the liver diagram even though it was emphasised to be a very important vein during lectures and workshops. I hope everyone is doing well during these times and good luck to anyone going into exams like I am.

Silk Me Back – Arterial Kimono

Gorgeous kimono featuring the human arterial system designed by FMR for an exhibition in France, called Silk Me Back at the Nesle Gallery. Created to support victims of the Fukushima nuclear plant disaster, this exhibition featured 25 stunning kimonos like the one above. All of the kimono’s will be auctioned off on February 9th, 2013 in the Westin-Paris Vendôme hotel in Paris. Profits will be donated to KNK Japan/Children Without Borders and the Furusato Project.

If you look closely, you can see that the arterial system on the silk kimono is all handwritten with text from the Buddhist Sutta.  Stunning detail down to the drops of blood on the collar!
