Blood pressure change in normal pregnancy
Give this one a try later!
- progesterone relaxes smooth muscle in the wall of blood vessels
- relaxin increases systemic arterial compliance (vasodilation) to reduce
peripheral resistance
- decreases the effective circulating volume (same volume but larger space
to fill)
, - effects of vasodilation:
•non-osmotic release of vasopressin/ADH
•activation of SNS and RAAS increases plasma volume for adequate organ
perfusion
Intervillous space
Give this one a try later!
- the space in the placenta in which maternal blood bathes chorionic villi,
allowing the exchange of materials between the fetal and maternal
circulations.
Divided into 3 parts:
- arterial circulation
- circulation in the intervillous space
- venous drainage
Congenital effects of Hepatitis B
Give this one a try later!
- none
- developing fetus does not get infected
- neonate is treated at birth if mother is infected
Maternal cardiovascular changes
