Placenta is expelled by the ?
Mother
Umbilical Arteries atrophy and become?
Lateral Umbilical Ligaments
________ becomes the round ligament (Ligamentum Teres) of the liver.
Umbilical Veins
_______ becomes the Ligamentum Venosum
Ductus Venosus
A fibrous cord in the liver
Ligamentum Venosum
It becomes a depression in the Interatrial Septum
Fossa Ovalis
The ductus arteriosus atrophies and becomes the ?
Ligamentum Arteriosum
A reddish brown disk, about 20cm long and 2.5 cm thick
Placenta
The placenta consists of 15-20 segment called
Cotyledon
Cotyledon provides an interface between the
Maternal and fetal circulation
The three main structures in the Cotyledons
- Fetal Vessels
- Chorionic Villi
- Intervillous Spaces
Each cotyledons contains
Maternal and Fetal blood vessels
Basic structural and functional unit of the placenta
Cotyledons
The cotyledons is surrounded by millions of
Fetal Capillaries
It carries deoxygenated blood from the fetus to placenta
Umbilical Arteries
It carries oxygentated blood from the placenta to fetus
Umbilical Veins
The oxygenated blood from the intervillous spaces is collected by the
Umbilical Vein
This oxygen-rich blood is transported through the
Umbilical Cord
A blood vessel that bypasses the lungs in Utero
Ductus Arteriosus
A hole in the heart between the atria
Foramen Ovale
temporary vessels/openings that allows flow of food/substance
shunts
an opening between the two atria (upper chambers) of the fetal heart
Foramen Ovale
It is a vessel that connects the pulmonary artery to the descending aorta allowing blood to bypass the fetal lungs
Ductus Arteriosus
What are the 10 changes?
- Breathing Changes
- Circulatory Changes
- Thermoregulation
- Metabolic Adaptations
- Gastrointestinal Changes
- Renal Function
- Immune System Activation
- Neurological Adaptations
- Excretion of Amniotic Fluid
- Sensory Stimulation
