These are normal physiological adaptations that cause changes in behavior, the functioning of the heart, blood vessels, and blood, metabolism including increases in blood sugar levels, kidney function, posture, and breathing. During pregnancy numerous hormones and proteins are secreted that also have a broad range of effects.
Amniotic fluid. The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus. For humans, the amniotic fluid is commonly called water or waters ...
The fetal circulatory system includes three shunts to divert blood from undeveloped and partially functioning organs, as well as blood supply to and from the placenta. In humans, the circulatory system is different before and after birth. The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical ...
Body water. In physiology, body water is the water content of an animal body that is contained in the tissues, the blood, the bones and elsewhere. The percentages of body water contained in various fluid compartments add up to total body water (TBW). This water makes up a significant fraction of the human body, both by weight and by volume.
Many women consider natural birth empowering and giving women more control in the birth process, pushing against the paternalistic medical establishment. [ 7 ] [ 4 ] They prepare for the delivery of their children by accepting that they will have contractions, finding solace when needed, and feeling confidence in their capacity to give birth. [ 8 ]
Most people can tolerate a 3-4% decrease in total body water without difficulty or adverse health effects. A 5-8% decrease can cause fatigue and dizziness. Loss of over 10% of total body water can cause physical and mental deterioration, accompanied by severe thirst. Death occurs at a loss of between 15 and 25% of the body water. [4]
Obstetrics, midwifery. A breech birth is when a baby is born bottom first instead of head first, as is normal. [1] Around 3–5% of pregnant women at term (37–40 weeks pregnant) have a breech baby. [2] Due to their higher than average rate of possible complications for the baby, breech births are generally considered higher risk. [3]
Body fluids, bodily fluids, or biofluids, sometimes body liquids, are liquids within the body of an organism. [1] In lean healthy adult men, the total body water is about 60% (60–67%) of the total body weight; it is usually slightly lower in women (52–55%). [2][3] The exact percentage of fluid relative to body weight is inversely ...
