Blood vessels start in the periphery!
The first immediate action of the blastocyst when burrowing into the nutrient rich Uterine wall is to harvest nutrients, oxygen and fluids, as well as bring carbon dioxide and urea to be released from the embryo. The cells on the outside of the trophoblast grow rapidly into this wall and immediately creates small blood islands. It also breaks down the tissues of the mothers womb into a pool of nutrients and blood, at which time it grows tentacles into these blood and nutritious pools to harvest this rich food. In order to bring the nutrients in - it connects its blood islands into veins and arteries =FLOW! and this flow connects them with the blood vessels that are being built in the body of the becoming embryo.
The embryo is highly motivated to connect to a source of nourishment! Once it sticks to a spot on the uterine wall, it uses all of its resources to make it's way into the inviting uterine wall - great amounts of innovation and energy starts on the peripheral cells. Also the developing yolk and the becoming body begin to populate the organism with blood islets, that join up to become veinules ( little veins) and arterioles, then larger and larger channels, until FLOW starts. Flow starts in these joining blood islands that strive to harvest the nutrients and oxygen on the mother, the yolk and to connect these to the body body of the embryo - to circulate.
Although we humans have a similar map for our arteries and veins - there is considerable individuality in these maps....see if you can touch different people with the excitement of this time in embryology and notice their specific map, the traces of this rousing phase of life.
After the embryo has established this nutrient rich connection - it starts to focus its harvest into the growing placenta and the growing yolk sac. In this time the embryo starts establishing the fluids it will swim in ( amniotic, now a bubble on one side of the inner cells, and chorionic - whichsurrounds all tissues even the amnion) All tissues grow dramatically until it grows out of the uterine wall and suspends into the uterine cavity.
All these structures that start from the periphery of the embryo as well as in the becoming body actually start creating rhythms, pump in concert with each other , long before the primitive heart at 4 weeks starts pumping. Arteries and veins to a lesser extent have their own muscle contractions that move blood, cells draw the oxygen and nutrients in and even each blood cell has a sense of contractile rhythm: the whole organism is alive with this pumping.
Don't let your heart carry it alone, Let it be embedded into the vibrant bed of cells that can move, blood vessels that move the flow and finally your heart that receives all this support and activity as it sets time for this exchange.
Excerpt from a workshop description by Nicole Binder, BMC practitioner:
......The arterial blood swirls out toward the distal parts of the body and has a repetitive, pulsing rhythm. The venous blood whorls back toward the heart and has a wavelike rhythm. The place where the arterial and venous capillaries meet is called the isoring, a resting place between coming and going. Through balancing this inward and outward flow and finding the meeting place of stillness, we can move with more facility between solo dancing, meeting others, and sharing weight.
This workshop will also explore polarities as they manifest in the blood and cerebrospinal fluid, which are the heaviest and lightest fluids in the body. In utero the blood forms in the yolk sac in the front, and the cerebrospinal fluid arises from the amniotic fluid in the back. Within these two fluids we can find opposition and balance between front / back, inner / outer, gravity / space, folding / extending, rolling / sloughing, and underdancer / overdancer. The transitions between these poles are nonlinear and take us into spiral pathways......
- 1st video - watch without sound and notice how the outer tissues of the embryo relate to the uterine wall
- 2nd video - at 3:40 you can see how fast the new heart is pumping!
- Placenta video - midwife shows how the amniotic sac connects to the placenta - she is also just so relaxed!!
- 4th video might inspire you to draw!!
- 8 Medical Embryology - go to 13:25- 15:10 it shows the blood islands in the arch that becomes that heart that have not fused yet! then 17:40 on it shows the heart tube shifting to bend and wrap around itself. Don't worry about all the other details!!

Watch out for how the embryo's system creates blood vessels, then connects these into veins and arteries to harvest nutrients from the tissues close to the mother's capillaries.
Then notice that it establishes blood vessels to feed on its own yolk sac, transforming this nourishment into cells, organs, tissues of its new body.
