PPT-Unit-8 EMBRYOLOGY FETAL CIRCULATION

Date of Lecture 30052020 Dr Manoj Kumar Sinha Asst professorcumJr scientist Department of veterinary Anatomy FETAL CIRCULATION The circulation of oxygenated blood deoxygenated blood and nutritive materials in the fetus is termed as . e. xtrauterine. . l. ife. Darja Paro Panjan. Department of . neonatology. University Children’s Hospital Ljubljana. Aim. To understand physiologycal changes in different organ systems after birth. Portal Circulation. The . hepatic portal system . is designed to take nutrient- rich venous blood from the digestive tract capillaries, and transport it to the sinusoidal capillaries of the liver.. As it percolates through the liver sinusoids, the hepatocytes of the liver, acting as the chemical factories of the body, extract and add what they wish to maintain homeostasis (extracting sugars, fats, proteins when appropriate and then dumping them back into the circulation when necessary).. e. xtrauterine. . l. ife. Darja Paro Panjan. Department of . neonatology. University Children’s Hospital Ljubljana. Aim. To understand physiologycal changes in different organ systems after birth. From Egg to Embryo. A. Terms. 1. Pregnancy – events occurring from the time of fertilization (conception) until the infant is born. 2. Gestation period – extends from the last menstrual period until birth (280 days). You will notice similarities . among organisms in their . early . stages. . The similar . embryo . development means . they all descend from a common ancestor. The similarities amongst organisms . fades as the organism develops.. 1. These are the lower compartments of the heart. Circulation Review. 2. This vein feeds the right atrium.. Vena Cava b. Pulmonary Vein . c. Femoral Vein d. Pulmonary artery. Circulation Review. 3. This artery leaves the right ventricle.. Christopher Casteel, RRT-ACCS, NPS, AE-C, C-NPT. Fetal Development / Early Stages. The fertilized egg, or zygote, implants into the uterus. . The zygote is completely dependent on the uterine lining for nourishment. Cell division begins to occur and the grouping of cells at this point is called a blastocyst.. Assessment of Fetal Well Being Heather M. Said , DO Assistant Professor, Maternal Fetal Medicine Learning Objectives Discuss advantages and disadvantages of external versus internal fetal monitoring Be able to interpret fetal heart tracing It will be covered again….

Implantation of Embryo . . AND . . Development . of Placenta). . . Date of Lecture 07.05.2020. Course Instructor – Dr. Manoj Kumar . Fetal. Circulation. Does lung development end at birth?. What does an infant need to be able to do at birth?. What does lung development include?. 50 . - . 250 million. 3 m. 2. . - . 70 m. 2. Embryonic Period . In the fully developed human, the heart serves two main purposes. . The right heart pumps blood to the lungs for oxygenation and the left heart pumps oxygenated blood to rest of the body. . In the embryo and fetus, the lungs do not oxygenate the blood. . Anatomy and Physiology. Fetal Circulation. Umbilical cord. 2 umbilical arteries: return non-oxygenated blood, fecal waste, CO2 to placenta. 1umbilical vein: brings oxygenated blood and nutrients to the fetus. Kathy Setter.
