[Time course of changes in the volume of blood cells in pregnancy]
Abstract:
The time course of changes in the parameters of the corpuscular volume of red blood cells, lymphocytes, neutrophils, and platelets was studied during uncomplicated pregnancy. It was ascertained that in pregnancy, the mean volume of red and white blood cells and that of platelets remained steady-state. Adaptive changes were observed in the fine structure of blood cells of all types. Factor analysis demonstrated that evaluation of a system of parameter intercorrelations in the distribution of blood cells by their volume allows pregnancy phases to be clearly differentiated.

The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...
Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Secretory Phase
Following ovulation, the corpus luteum, a temporary endocrine structure, produces progesterone and estrogens. These hormones stimulate the growth and coiling of endometrial...
Proliferative Phase
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...
