Hey, everyone. Let's take a look at this question together. What substance lubricates the joint and reduces friction. Is it answer choice. A synovial fluid, answer choice B collagen, answer choice C, Elastin or answer choice D hormones. Let's work this problem out together to try to figure out which of the following answer. Choices is what is responsible for lubricating the joints to reduce friction. So in order to solve this question, we have to recall what each of the following answer choices are responsible for to determine which is the substance that is responsible for lubricating the joint to reduce friction. And we can recall that the fluid that lubricates the joints to reduce friction is synovial fluid, which that synovial fluid is a fluid that is found in the synovial cavity of synovial joints. And that synovial fluid is crucial for facilitating smooth movement between the articulating bones, reducing weight and tear during movement because of that reduced friction. So looking at our answer choices, we can identify answer choice. A synovial fluid as the correct answer. Since that synovial fluid is the substance that lubricates the joints and reduces friction. And all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
