Question | Answer |
What is a Membrane? | A Membrane is a sheet-like structure on the outside of a cell. Molecules use passive and active transport to diffuse through the membrane. It is semi-permeable. |
What is Diffusion? | Diffusion is the movement of molecules, through air, water and membrane, from a greater concentration to a lesser concentration. |
What is Passive Transport? | Passive Transport is when a molecule can pass through a membrane without using any energy from the cell so the cell has energy for active transport. There is no energy needed in this process. |
What is a Specialization? | A Specialization is what the organ does as its job in the body. Each enzyme only digests one type of food. |
What is the Small Intestine? | It is a 2.5 cm in diameter, approximately 6m long liquid-filled tube. It is a major part of digestion, it absorbs nutrients from chyme as it moves from the stomach to the large intestine. Fats, proteins and carbs get digested. Neutralizes acids. |
What is Active Transport? | Active transport is when a molecule is pulled through the membrane using energy from its cell because it is too large for passive transport. |
What is Pancreatic Juice? | Pancreatic juice is a non-acid digestive juice that comes from the pancreas packet with enzymes that help digest carbs, fats, and proteins. |
2.5 cm is... | 2.5 centimeters is the diameter of the small intestine. |
What is the Gallbladder? | An organ that stores bile that was made in the liver. |
What is a Pyloric Sphincter? | A Pyloric Sphincter is a circular muscle that opens in the center to allow chyme into the small intestine. A gateway from the stomach to the small intestine. |
What is Bile? | Bile is a greenish brown fluid that is made in the liver. It aids digestion and is stored in the gallbladder. |
