What else can I help you with?
What structure helps increase the surface area available for absorption?
The intestinal wall has invaginations (or dips) that have a much larger surface ares compared to a simple tube
What are tiny fingerlike projections that cover the folds of the small intestines?
The tiny fingerlike projections that cover the folds of the small intestine are called villi. Villi increase the surface area of the small intestine, allowing for more efficient absorption of nutrients from digested food.
How a placenta is adapted to carry out its function?
The placenta is adapted to carry out its function of providing nourishment and oxygen to the developing fetus by having a large surface area covered in villi for efficient exchange of nutrients and gases. It also has a rich blood supply from both the mother and the fetus, allowing for the exchange of substances between their circulatory systems. Additionally, the placenta produces hormones that help maintain the pregnancy and support fetal development.
The small intestine is covered in millions of villi what are villi and what is their job?
Villi are fingerlike projection from a surface and in the intestine they are one cell thick with blood vessels and lacteal. The funciton is to increase the surface area of the intestine and so increasing the ammount of absorption.
Why are villi so important in the digestive process?
Villi are found in our small and large intestines, and are adapted to their function by having a very large Surface Area to volume ratio. They are vital as they extract the vital nutrients from the food we eat and are absorbed into the blood supply which runs just underneath the villi, and transport these nutrients to wherever they are needed.

What does Chorionic villi become?
Chorionic villi develop into the placenta, an organ that provides oxygen and nutrients to the developing fetus and removes waste products. The placenta also plays a crucial role in hormone production to support pregnancy.
What are tiny fingerlike projections that cover the folds of the small intestines?
The tiny fingerlike projections that cover the folds of the small intestine are called villi. Villi increase the surface area of the small intestine, allowing for more efficient absorption of nutrients from digested food.
What structures form the placenta?
Chorionic villi & Decidua Basalis
What is a lining if the small intestine?
the lining of the small intestine has folds, and are covered with finger-like projections called villi, which are covered with thousands of micro-villi
How a placenta is adapted to carry out its function?
The placenta is adapted to carry out its function of providing nourishment and oxygen to the developing fetus by having a large surface area covered in villi for efficient exchange of nutrients and gases. It also has a rich blood supply from both the mother and the fetus, allowing for the exchange of substances between their circulatory systems. Additionally, the placenta produces hormones that help maintain the pregnancy and support fetal development.
What structures ultimately forms the placenta?
Chorionic villi & Decidua Basalis
What two tissues does placenta form?
trophoblasts/chorionic villi and the uterus form the placenta
What is the reason for the Villi?
The villi increases the surface area for the small intestine.
How the structure of the placenta is related to its function?
The structure of the placenta is related to its functions because its functions is to support the embryo/foetus in ways such as providing it with nourishment, and oxygen which explains the relevance of the placenta to its function of supporting the growing individual.
