Anatomi Systema Cardiovasculare : Sirkulasi fetus
Summary
TLDRThis educational video script discusses the fetal circulation system, focusing on the umbilical cord's connection to the fetus and mother. It explains the unique blood flow through the umbilical vein and arteries, including the role of the ductus venosus and foramen ovale. The script also highlights the changes that occur at birth, such as the closure of the foramen ovale and the transformation of the umbilical structures into ligaments, reflecting the shift from fetal to neonatal circulation.
Takeaways
- 🔴 The fetal blood circulation is connected to the mother through the umbilical cord.
- 🩸 The umbilical cord contains one vein and two arteries.
- 🌐 The vein, called the umbilical vein, carries oxygen and nutrients from the placenta to the fetus.
- 🔄 The two arteries, known as the umbilical arteries, carry blood back to the placenta to be cleansed of metabolic waste.
- 📍 After birth, the umbilical vein becomes the ligamentum teres hepatis.
- 💧 The umbilical vein passes through the abdominal wall and goes cranially to the liver.
- 🔄 The blood from the umbilical vein enters the inferior vena cava and then the right atrium of the heart.
- 🫀 The blood from the inferior vena cava has a low oxygen level, but the blood from the umbilical vein is highly oxygenated.
- 🚫 The foramen ovale allows the oxygen-rich blood to bypass the lungs and enter the left atrium.

🩺 Fetal Circulation Explained
This paragraph discusses the circulation of blood in a fetus. It is connected to the mother through the umbilical cord, which contains one vein and two arteries. The vein, known as the umbilical vein, carries oxygen and nutrients from the placenta to the fetus. After birth, this vein becomes the ligamentum teres hepatis. The two arteries, called the umbilical arteries, carry blood back to the placenta to be cleansed of metabolic waste. One of the arteries is mentioned to become the ligamentum arteriosum after birth. The umbilical vein passes through the abdominal wall and heads cranially towards the liver. It then goes through the ductus venosus, which becomes the ligamentum venosum after birth, and joins the inferior vena cava, entering the right atrium. The blood from the umbilical vein, rich in oxygen, mixes with the lower oxygen blood from the inferior vena cava. The foramen ovale, present in the right atrium, allows oxygen-rich blood to bypass the lungs and enter the left atrium. After birth, this foramen closes. The paragraph also explains the role of the ductus arteriosus, which connects the pulmonary artery to the aorta, allowing blood to bypass the lungs and go directly to the body. This ductus closes after birth.
🌟 Changes in Circulation After Birth
The second paragraph focuses on the changes that occur in the circulatory system at birth. With the development of the lungs and the increase in oxygen pressure, the umbilical cord constricts, leading to changes in circulation. The foramen ovale closes for the first and last time, and the ductus venosus closes within three days, becoming the ligamentum venosum. The changes include the ductus arteriosus becoming the ligamentum arteriosum, the foramen ovale closing to form the fossa ovalis, and the umbilical vein becoming the ligamentum teres hepatis. The ductus venosus also changes, and the umbilical arteries transform into ligamentum structures. These changes mark the transition from fetal to neonatal circulation.

Highlights
Introduction to fetal blood circulation study at FK UNS laboratory.
Fetal blood circulation is connected to the mother through the umbilical cord.
The umbilical cord contains one vein and two arteries.
The vein carries oxygen and nutrients from the placenta to the fetus.
The vein is called the umbilical vein, which becomes the ligamentum teres hepatis after birth.
The two arteries carry blood back to the placenta for metabolic waste removal.
These arteries are called the umbilical arteries.
The umbilical vein passes through the abdominal wall and goes cranially.
The vein then passes through the ductus venosus, which becomes the ligamentum venosum after birth.
Blood from the umbilical vein enters the inferior vena cava and then the right atrium.
Blood from the inferior vena cava has a low oxygen level.
The foramen ovale allows oxygen-rich blood to bypass the lungs.
The foramen ovale closes after birth, becoming the fossa ovalis.
Blood from the superior vena cava mixes with blood from the inferior vena cava and is circulated throughout the body.
The ductus arteriosus allows blood to bypass the lungs and directly enter the aorta.
After birth, the ductus arteriosus closes and becomes the ligamentum arteriosum.
Changes in fetal circulation after birth include the closure of the umbilical vessels and ducts.
The foramen ovale closes for the first and last time after birth.
The ductus venosus becomes the ligamentum venosum.
The umbilical vein becomes the ligamentum teres hepatis.
The umbilical arteries become the ligamentum bingkai remedial.

Halo assalamualaikum warahmatullahi
wabarakatuh Selamat datang di
laboratorium anatomi FK UNS bersama saya
nafau Nisa asisten laboratorium anatomi
FK UNS angkatan 2019 kali ini kita akan
pelajari materi peredaran darah fetus
nah sebelum pelajari materi peredaran
darah fetus ini Maka jangan lupa ya
untuk mempelajari terlebih dahulu materi
Anatomi jantung dan juga peredaran darah
pada manusia dewasa Oke mari sekarang
kita mulai
Hai peredaran darah fetus dihubungkan
dengan ibu melalui tali pusat Oke
talipusat berisi satu Vena dan dua
Arteri disini terdapat satu Vena dan ada
dua Arteri nah Vena ini akan menyalurkan
oksigen dan juga nutrisi dari plasenta
ke janin dan vena ini disebut dengan
Vena umbilicalis yang setelah lahir akan
menjadi ligamentum teres hepatis nah
kedua Arteri ini akan menjadi pembuluh
darah balik yang menyalurkan darah ke
arah plasenta untuk dibersihkan dari
sisa metabolisme kedua Arteri ini
disebut dengan arteria umbilikalis
Hai nah oh Vena umbilicalis setelah
melewati dinding abdomen akan mengarah
ke cranial atau ke atas dia akan meminta
hepar
Hai kemudian melewati suatu duktus yang
bernama duktus venosus arantii yang
kemudian setelah bayi lahir akan menjadi
ligamentum venosum aranti dan akan
bergabung di Vena cava inferior masuk ke
atrium dextrum
Hai darah yang masuk ke atrium dextrum
ini karena berasal dari Vena umbilicalis
maka mengandung kadar Oksigen yang
tinggi meskipun bergabung dengan darah
dari Vena cava Vena cava inferior yang
ada oksigennya rendah
hai oh ya jika teman-teman sudah
mempelajari Anatomi jantung teman-teman
sudah tahu kan bahwa darah dari Vena
cava inferior ini akan masuk Atrium
dextrum melewati Ostium Vena cava
inferior is nah terkait dengan Ostium
ini terdapat suatu lipatan bernama
valvula Vena cava inferior is shalat
Vena cava inferior ini akan membantu
mengarahkan aliran darah teroksigenasi
yang datang melewati foramen ovale masuk
ke atrium sinistrum Nah jadi darah dari
Vena cava inferior tadi setelah memasuki
Atrium dextrum akan diarahkan langsung
menuju ke atrium sindetsindet ROM
melewati foramen ovale yang telah lahir
akan menjadi sosok alis Dimana letaknya
tepat di atas Ostium Vena cava inferior
is pada septum interatrial ini saya
Tunjukkan gambarnya masalah
Hai nah odd disini terdapat of Korra Men
of valor De
Hai yang akan langsung membuat darah
masuk ke atrium sinistrum
Hai hehe
Hai nahos kemudian darah akan masuk ke
atrium chord Disini Strong dan
selanjutnya melalui ventrikulus kondisi
Mister akan langsung menuju aorta dan
seluruh tubuh
Hai jadi tadi sudah kita ketahui bahwa
pada Atrium dextrum terdapat syukur
bernama foramen ovale sedangkan pada
aspek Atrium sinistrum kita dapat
menemukan struktur katup yaitu valvula
format forum milis ovalis selama
perkembangan valvula Families of alis
ini akan mencegah darah lewat dari
Atrium sinistrum kembali ke atrium
dextrum Nah tadi kita sudah bahas
mengenai Darah yang berasal dari Vena
cava inferior Bagaimana negara dengan
darah dari Vena cava Superior jadi darah
dari Vena cava Superior ini akan masuk
ke atrium cordis dextrum kemudian akan
turun ke ventrikulus cordis Dexter dan
kemudian sebagian besarnya akan
dialirkan ke aorta melalui suatu saluran
bernama duktus arteriosus botalli jadi
atmanti sudah belajar bahwa ada
peredaran darah dewasa darah dari
ventrikel skor distrikstore akan masuk
ke pulmo akan tetapi it
Hai ada fetus darah akan melewati
trunkus pulmonalis tapi akan dialirkan
ke aorta melewati duktus arteriosus
bertali yang telah lahir akan menjadi
ligamentum arteriosum botalli yang
menghubungkan Arteri pulmonalis sinistra
dengan artis Artha nah darah ini
langsung dialirkan ke aorta karena
volume pada fetus belum berkembang
Walaupun ada sebagian kecil darah yang
mengalir ke promo
Hai nah darah dari Vena cava Superior
ini merupakan daerah dengan kadar
Oksigen yang rendah darah ini akan
bergabung di Aura descendants dan
bercampur dengan darah bersih dari Vena
cava inferior dan akan dialirkan
keseluruh tubuh
Hai Nah selanjutnya adalah darah balik
darah balik pada fetus akan melalui
Arteri hipogastrika kemudian keluar
melalui dinding abdomen sebagai arteria
umbilikalis nih
Hai Nah setelah baik Nah setelah bayi
lahir semua pembuluh umbilikalis duktus
venosus dan juga Doctors arteriosus akan
mengkerut pada saat lahir akan terjadi
perubahan sirkulasi dimana terjadi
pengembangan paru dan juga penyempitan
tali pusat akibat peningkatan tekanan
oksigen pada sirkulasi paru dan vena
pulmonalis foramen ovale akan menutup
untuk pertama dan terakhir kalinya itu
sartorius akan menutup dalam tiga hari
dan total pada minggu
Hai Nah dari penjelasan tadi bisa teman
mencermati ada beberapa struktur yang
berbeda pada sirkulasi darah fetus untuk
menutup pembahasan ini berikut rangkuman
beberapa struktur yang ada pada
peredaran darah fetus tetapi berubah
pada saat lahir di antaranya ada duktus
arteriosus putali yang berubah menjadi
ligamentum arteriosum tali kemudian
foramen ovale yang menutup menjadi fossa
ovalis duktus venosus arantii yang
berubah menjadi ligamentum venosum
aranti Vena umbilicalis yang berubah
menjadi ligamentum teres hepatis dan
terakhir Arteri umbilikalis yang berubah
menjadi ligamentum bingkai remedial Nah
mungkin sekian penjelasan dari saya
semoga bermanfaat dan dapat dipahami
Terima kasih Bu
