Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
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...
Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
Ovarian Cycle01:27

Ovarian Cycle

The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
Physiological Barriers01:25

Physiological Barriers

Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...
Histology of the Uterus01:19

Histology of the Uterus

The uterine wall consists of three histological layers: the perimetrium, myometrium, and endometrium. The outermost perimetrium is a thin, serous membrane connected with the broad ligament on the sides, which helps anchor the uterus in the pelvic cavity. The thickest layer, myometrium, is mainly made up of smooth muscle tissue bundles. Its contractions are vital in facilitating the expulsion of the uterine lining, fetus, and placenta during menstruation and childbirth.
The endometrium is the...

Summary

The placenta acts as a record of the intrauterine environment, offering insights into the timing and causes of adverse pregnancy outcomes. Examining placental abnormalities helps determine injury origins and duration, crucial for infant health.

Area of Science:

  • Perinatal Medicine
  • Pathology
  • Obstetrics

Background:

  • The placenta reflects the intrauterine environment and pregnancy health.
  • Placental examination can reveal causes of adverse outcomes.

Purpose of the Study:

  • To highlight the diagnostic value of the placenta in understanding adverse pregnancy events.
  • To emphasize the placenta's role in determining the etiology and timing of fetal injury.

Main Methods:

  • Review of placental pathology.
  • Correlation of placental findings with intrauterine conditions and infant outcomes.

Main Results:

  • Placental abnormalities can be the primary cause of injury or a consequence of other diseases.

  • Placental examination identifies the origin and timeline of abnormal conditions.
  • Acute and chronic placental lesions indicate different types of adverse events and their impact on infant health.

    • Conclusions:

    • The placenta is a critical diagnostic tool for understanding adverse pregnancy events.
    • Placental analysis provides insights into injury etiology and temporal progression.
    • Placental reserves depletion significantly increases infant susceptibility to injury and mortality.
