Final answer:
Factors influencing blood clotting, weight gain, and thermoregulation are related to maternal diet, breastfeeding, gut bacteria, vitamin K shot, liver function, genetics, and the adaptation of the newborn's body after birth.
Step-by-step explanation:
Factors influencing blood clotting
During fetal development, the placenta secretes inhibitors that prevent metabolism of brown adipose fat and promote its accumulation in preparation for birth. Breast milk provides immunoglobulins that increase the newborn's immune defenses, helping to clot blood when necessary. Additionally, the production of vitamin K in the intestine is also important for blood clotting.
Factors influencing weight gain
Genes play a major role in determining our adult height, but factors like poor nutrition can prevent us from reaching our full genetic potential for weight. Environmental factors like diet and physical activity also influence weight gain.
Factors influencing thermoregulation
The breakdown of brown fat occurs automatically upon exposure to cold, which helps regulate body temperature. Additionally, the first breath a newborn takes at birth inflates the lungs and alters the circulatory system, closing the shunts that directed oxygenated blood away from the lungs and liver during fetal life, further aiding in thermoregulation.
