Structure Of Placenta Ppt

: The core of the villus, containing mesenchymal cells and specialized macrophages called Hofbauer cells .

: This side attaches to the uterine wall and is divided into 15–28 irregular lobes called cotyledons by decidual septa. Histological Structure (Microscopic Layers)

Slide 7: Functions of Placenta

⭐⭐⭐⭐ (4.5/5)

The human placenta is a complex, temporary "fetomaternal" organ that serves as the life-support system for a developing fetus. For a presentation or in-depth study, understanding its structure involves looking at both its gross anatomy and microscopic layers. Gross Anatomy of the Mature Placenta

If you need a ready-to-teach, accurate, and visually clear lecture base on placental anatomy, this PPT is an excellent choice. It’s especially strong for 50–90 minute lectures. Just supplement it with a short video of placental blood flow and a few multiple-choice questions to consolidate learning.

The placenta consists of several layers, which are: structure of placenta ppt

cotyledons by septa. 2. Microscopic Structure The placenta is "hemochorial," meaning maternal blood comes into direct contact with fetal tissue (the chorion). Chorionic Villi: The functional units. These finger-like projections extend into the maternal blood-filled spaces. Placental Barrier: A thin membrane separating maternal and fetal blood. It consists of: Syncytiotrophoblast (outer layer) Cytotrophoblast (inner layer) Connective tissue (mesoderm) Endothelium of fetal capillaries 3. The Maternal-Fetal Interface Intervillous Space: The "pool" where maternal blood circulates. Maternal spiral arteries spurt oxygenated blood into this space. Decidua Basalis: The part of the uterine lining (endometrium) where the placenta is anchored. 4. Key Functions Exchange: Oxygen and nutrients move from mother to fetus; carbon dioxide and waste (urea) move from fetus to mother. Endocrine: Produces vital hormones like : The core of the villus, containing mesenchymal

The placenta is a vital organ that develops in the uterus during pregnancy. It plays a crucial role in providing oxygen and nutrients to the fetus and removing waste products. The structure of the placenta is complex and consists of both maternal and fetal components.

The chorionic villi are the functional units of the placenta. They consist of:
