What else can I help you with?
When the lungs do not function in a fetal pig what takes over their function?
The placenta. Deoxygenated blood flows to the placenta where the carbon dioxide is removed and oxygen added. Oxygen rich blood returns to the fetus. Blood is carried to and from the fetus by the umbilical cord.
What ductus arteriousis?
The ductus arteriosus is a blood vessel in fetal circulation that connects the pulmonary artery to the aorta, allowing blood to bypass the nonfunctional lungs. It normally closes shortly after birth to redirect blood flow through the lungs for oxygenation. If it remains open (patent ductus arteriosus), it can cause abnormal blood flow and require medical intervention.
Systemic circulation occurs when the right ventricle pumps blood to the lungs?
Actually, systemic circulation is when the left ventricle pumps oxygenated blood from the heart out to the rest of the body for delivery of nutrients and removal of waste products. Pulmonary circulation is when the right ventricle pumps blood to the lungs for oxygenation.
What major organ system is bypassed in fetal circulations other than for purpose of nutrition?
The lungs are the major organ system bypassed in fetal circulation, as the fetus receives oxygen and nutrients from the mother through the placenta instead of through respiration. Once born, the ductus arteriosus and foramen ovale close, redirecting blood flow to the lungs for oxygenation.
Why red blood cells explode?
over oxygenation - too much oxygen intake for the blood cells to handle
Where does oxygenation of fetal blood occur?
Oxygenation occurs in the placenta. After this blood then returns to the fetus via the umbilical vein.
How does the fetal circulation work?
The blood goes from the mother to the placenta where gas exchange occurs to the fetus. From the placenta the blood goes into the arterium and to the body of the fetus.

In the mammalian fetus where does fetal blood exchenge carbon dioxide for oxygen?
In the mammalian fetus, the exchange of carbon dioxide for oxygen occurs in the placenta. The placenta is a temporary organ that develops during pregnancy to allow for the transfer of gases, nutrients, and wastes between the maternal and fetal bloodstreams. Oxygen from the mother's blood diffuses into the fetal blood, while carbon dioxide from the fetus diffuses into the mother's blood for elimination.
What is the definition intrapartum asphyxia?
intrapartum asphyxia occurs when there has been an inadequate assessment of heart rate monitoring and fetal blood samples.
Where does the blood in a coronary artery go?
to the lungs for oxygenation then to blood stream
How does the ductus arteriosus improve the effciency of fetal circulation?
The ductus arteriosus is a critical fetal blood vessel that connects the pulmonary artery to the aorta, allowing blood to bypass the non-functioning fetal lungs. This shunt enables oxygen-rich blood from the placenta to flow directly into the systemic circulation, enhancing the efficiency of oxygen delivery to the developing tissues. By diverting blood away from the lungs, the ductus arteriosus ensures that the fetus maintains adequate oxygen supply while in a low-oxygen environment. After birth, this vessel typically closes, directing blood through the lungs for oxygenation.
Where does oxygenation take place?
Blood is oxygenated in the lungs!

What is the process where blood picks up oxygen and drops off carbon dioxide called?
When red blood cells pick up oxygen they are said to become oxygenated. The process is oxygenation.
How does the Cadiovascular system work with the Respiratory system?
Oxygenation of blood
