In order to better understand cardiac defects, it’s best to start off reviewing how a normal heart works. First, the Superior and Inferior Vena Cava carrydeoxygenated blood into the heart (Right Atrium) from other parts of the body. The deoxygenated blood then passes through the TricuspidValve into the Right Ventricle. Thedeoxygenated blood is following the pathway through the heart in order to get to the lungs to gain oxygen, next the blood passes through the PulmonaryValveand enters the Pulmonary Artery, the pulmonary artery is special because it is the only artery in the body that carries deoxygenated blood. Once the deoxygenated blood passes through to theLungsit becomes oxygenated. The newly oxygenated blood then flows back to the heart through the Pulmonary Veins and into the Left Atrium. It then passes through the MitralValveand into the Left Ventricle. The blood is then contracted through the AorticValveinto the Aortaand to the rest of the body.
The Fetal Heart: During the fetal period and some time after birth, the circulation is quite different. The heart has more, holes, if you will in order for the fetal blood to bypass the lungs that are unable to oxygenate blood while the fetus is in utero. - The Foramen Ovale is an opening that allows passage of blood from the Right Atrium directly into the Left Atrium. The blood passing through is already oxygenated from the placenta. - The Ductus Arteriosus is an opening that passes oxygenated blood from the Pulmonary Artery directly into the Aortato get pumped to the rest of the body.
I found this in an old sketchbook. I wanted to try and figure out how the skull of this anime person would look since her mouth is almost in line with where her eyes start.
Bird wing anatomy practice from earlier in the month. I had to draw bird wings in a certain pose for a project I’ve been hacking away at, and then realized I did not know how to properly draw bird wings. So I stopped that and did these over a few days.
Here are tutorials/anatomy breakdowns I found really helpful:
so… listen up baby!artists! this is mainly… my process and some thoughts i keep in the back of my head while drawing. there are different ways on how to draw teeth.
but when you are unsure always pull up a reference! or look at yourself in a mirror! take a selfie!
i just like to esagerate some shapes here
when you see this post. go wash your teeth and don’t forget to floss!!!

To include genitals or not to include genitals…. that is the question.
I think I was talked out of it by my team so we could have greater reach in conservative US schools. I think that normalizing differently shaped genitals is a really important message, and I suppose I don’t mind having that on the website instead.
[Hi, Boston! I’m Dr. Williams. You are probably familiar with the stereotypical male and female sexes for humans (these are called dyadic), but scientists have known for a long time that there’s way more options than that. We call these intersex, and it’s more common than you may think! These are normal and natural conditions and part of the beautiful diversity of human bodies. Just like we have lots of variation in hair color, nose shape, or height, we have many shades of gendered biology, too.
When it comes to our bodies, no two are exactly alike! Genitals are a great example of this. They come in all shapes and sizes and colors. Sometimes there’s a medical need for the body’s plumbing to be modified surgically at birth. However, doctors will often operate on infants with functioning genitals for no good medical reason - just to make their bodies look “normal.” This is terrible because it hurts children, makes lasting changes without consent, and sends a message that their bodies are not okay.
The truth is that all bodies are beautiful. But, your body doesn’t define you: you can have any gender identity or sexual orientation with any body type. Our bodies change as we grow. Sometimes our relationship with our bodies is part of how we understand our gender. The important thing is try to be a friend to your body and use words that feel good to you to describe it.
FYI box:The United Nations released a statement in 2013 condemning forced genital-normalizing surgery, but unfortunately, it still happens.11 Groups like InterACT are working to help advocate for the human rights of all children.]
This is a very rough draft from the upcoming version of the GENDER book I’m working on, posting here for community feedback. Please let me know what you think, where I am being problematic and how it could be better!

Animated Anatomies was curated by Valeria Finucci and Maurizio Rippa-Bonati with the assistance of Rachel Ingold and Meg Brown.
Animated Anatomies explores the visually stunning and technically complex genre of printed texts and illustrations known as anatomical flap books. These publications invite the viewer to participate in virtual autopsies, through the process of unfolding their movable leaves, simulating the act of human dissection. This exhibit traces the flap book genre beginning with early examples from the sixteenth century, to the colorful “golden age” of complex flaps of the nineteenth century, and finally to the common children’s pop-up anatomy books of today.
This display includes volumes from Duke’s Rare Book, Manuscript, and Special Collections Library, the Duke Medical Center Library & Archives History of Medicine Collection and from the private collections of the curators of the exhibit, Professor Valeria Finucci, Director of Duke’s Center for Medieval and Renaissance Studies, and Professor Maurizio Rippa-Bonati, historian of medicine at the University of Padua.
Animated Anatomies is an exhibit on display in the Perkins Gallery, Perkins Library, Duke University, Durham, North Carolina, from April 6-July 17, 2011, and in the History of Medicine Gallery in the Medical Center and Archives Library from April 13-July 17, 2011.
Santa Fe-based sculptor and jewelry designer Debra Baxter combines glass, bronze, crystal, wood, and found objects to create ghostly sculptures of human forms.
For many of her recent works Baxter shares with Roq Larue Gallery that she drew inspiration from the phenomenon of the “Ghost Heart.” In this medical procedure, a heart is cleansed of all of its blood cells and then injected with hundreds of millions of new blood steam cells which cause the heart to begin beating again. Baxter is interested in how this concept explores the complexity of existence, walking the line between life and death.
