This research paper delves into the intricate physiology process of pregnancy focusing on hormonal changes and profound impact of maternal nutrition on fetal development. It multifaceted in the world of pregnancy physiology offering a comprehensive examination of the intricate mechanisms that orchestrate the miraculous journey from conception to childbirth. To study physiology of pregnancy aims to deepen our understanding of complex physiological processes occurring during pregnancy. (i) To understand hormonal dynamics: Including the role of human chorionic gonadotropin, estrogen and progesterone to comprehend their impact on maintaining pregnancy. (ii) Explore cardiovascular adaptations: Examine cardiovascular changes that occur to meet fetal development demands during pregnancy, which includes increase in blood volume and increase cardiac output. (iii) Study placental function: Understanding the development of placenta examining the role of gas exchange, providing nutrition and excretion of waste products. (iv) Address complications and risks: Identifying the factors that contribute to risks and complications of pregnancy such as gestational diabetes, preeclampsia, and intrauterine growth restriction, aiming to implement strategy for prevention, early detection and management.
