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.

It will disrupt the process
Answer:
Carbon dioxide is a gas which is released in the atmosphere as greenhouse gas, burning of fossil fuel, released in respiration process. Rise in the levels of carbon dioxide and other gases has resulted in increase in global temperatures. Increase in carbon dioxide and temperatures are responsible for weather fluctuations and global warming.
Weather fluctuation means untolerated heat and lack of precipitation or rain. Weather fluctuations will affect seasons. Seasons are necessary for maintaining the life cycle of organisms. Inappropriate seasons due to climatic change will affect the life of living organisms.
Global warming is an issue which is mainly due to release of hot heat trapping gases from green house and other sources, increasing the atmospheric temperature. This will result in melting of ice from glaciers in world. The inhabiting animals living in the glaciers will suffer a lot from this as they cannot tolerate warm climatic conditions.
