List the cardiovascular and cardiac features unique to the fetus and describe their role in fetal circulation; explain the fate
STatiana [176]

Cardiovascular features unique to the Fetus:

Fetal circulation is characterized by low systemic vascular resistance (SVR) with high systemic blood flow and high pulmonary vascular resistance with low pulmonary blood flow.

<h3>What is fetal circulation?</h3>

The embryonic circulatory system directs blood that needs oxygen through three shunts, or microscopic tunnels. These shunts are intended to avoid forming organs like the liver and lungs while the fetus is still in the womb.

The foramen ovale, which carries blood from the right atrium of the heart to the left atrium, and the ductus arteriosus, which takes blood from the pulmonary artery to the aorta, are the two shunts that bypass the lungs.

Through the placenta, the mother's blood supplies the fetus with nutrition and oxygen. The enhanced blood divides into three branches as it travels via the umbilical cord to the liver.

In two or more complete sentences describe how a dam placed in a river can act as both a constructive and destructive force.
FromTheMoon [43]
The good thing about a dam is that electricity can be created by mechanical means. That does not affect the atmosphere. Storing such production is a different matter.

The bad thing about a dam is that it wreaks havoc on the land where the water is stored behind the dam.
