NTK
What Cardiovascular changes
occur during pregnancy?
Increased cardiac output, blood volume, and blood flow to the uterus.
Occurs due to ovarian and placental hormones.
NTK
What Respiratory changes
occur during pregnancy?
Thoracic cage and diaphragm shift;
sweating starts at lower temperatures.
NTK
What Metabolic shifts
occur during pregnancy?
Increased gluconeogenesis & insulin secretion,
with rising insulin resistance & increased lipolysis in mother.
NTK
What Maternal Metabolism
changes occur during pregnancy?
- Gluconeogenesis in the liver ↑,
- Insulin secretion ↑,
- Insulin resistance ↑
- lipolysis ↑
NTK
What Gastrointestinal changes
occur during pregnancy?
Slower motility, improved nutrient absorption.
What energy source do Fetus depend on?
Fetus depends on maternal glucose, with mechanisms in place to ensure sufficient supply.
What Renal system changes
occur during pregnancy?
