Diaphoresis | Sweatung
26
``` due to disproportionate increase between the circulating blood volume and RBC ```
PSEUDOANEMIA (Physiologic Anemia)
27
Maintains corpus luteum that produces | progesterone during first few weeks of pregnancy
Human Chorionic | Gonadotropin(HCG)
28
This hormone is responsible for Uterine and breast enlargement, Palmar erythema and hyperpigmentation
Estrogen
29
This hormone Maintains uterine lining, relaxes smooth muscles, promotes fat deposits
Progesterone
30
This hormone is responsible for the Softening of cervix, muscles and joints of pelvis. Inhibits uterine activity
Relaxin
31
This hormone modifies the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus
