FAQs on Types of Placentation Video Lecture - Biology for Grade 11
| 1. What is placentation? |  |
Ans. Placentation refers to the arrangement and attachment of the placenta within the uterus of a pregnant mammal. It is the process by which the developing embryo or fetus obtains nutrients and oxygen from the mother's blood supply.
| 2. How many types of placentation are there? | |
Ans. There are five main types of placentation:
1. Marginal placentation: In this type, the placenta is attached to the margin or edge of the ovary.
2. Axile placentation: Here, the placenta is attached to the central axis of the ovary, with multiple locules surrounding it.
3. Parietal placentation: In this type, the placenta is attached to the inner wall of the ovary.
4. Free central placentation: The placenta is attached to a central column in the ovary, and the ovules are located around it.
5. Basal placentation: In basal placentation, the placenta is attached to the base of the ovary.
| 3. Which type of placentation is most common in mammals? | |
Ans. The most common type of placentation in mammals is called "cotyledonary placentation." In this type, the placenta is formed by the combination of cotyledons (placental lobes) from the mother and the fetus. It is commonly found in ruminants such as cows, sheep, and goats.
| 4. How does placentation affect the development of the embryo? | |
Ans. Placentation plays a crucial role in the development of the embryo by facilitating the exchange of nutrients, gases, and waste products between the mother and the fetus. The structure and location of the placenta determine the efficiency of this exchange. Placentation also provides a physical attachment between the mother and the developing embryo, ensuring a stable environment for the embryo's growth and development.
| 5. Can placentation affect the outcome of pregnancy? | |
Ans. Yes, the type and quality of placentation can have a significant impact on the outcome of pregnancy. In some cases, abnormal placentation can lead to complications such as placenta previa (when the placenta covers the cervix) or placental abruption (when the placenta separates from the uterus prematurely). These conditions can cause bleeding, preterm birth, and other complications. It is important for healthcare providers to monitor placentation during pregnancy to ensure a healthy outcome for both the mother and the baby.
