Explain how the peritubular capillaries are adapted for receiving reabsorbed substances.

Video transcript

Hey, everyone. Let's take a look at this question together which of the following is incorrect about the adaptations in the peritubular capillaries for the reabsorption of various substances. Is it answer choice? A low blood pressure, answer choice. B high protein level answer choice C, low permeability or answer choice D, both answer choices A and B. Let's work this problem out together to try to figure out which of the following answer choices about the adaptations in the peritubular capillaries for the reabsorption of various substances is incorrect. So, in order to solve this question, we have to recall what we have learned about the peritubular capillaries. Specifically those adaptations for the reabsorption of various substances to determine which of the following answer choices is incorrect. And we note that the peritubular capillaries are found surrounding the cortical parts of the proximal and distal convoluted tubules or the PC T and DC T of A Nephron. And when it comes to their role in the reabsorption of various substances, we know that they aid in reabsorption by allowing the easy passage of water ions and small particles between the capillaries and the tubular cells and the easy passage of water ions and small particles is due to there I permeability. Since they are highly permeable, it allows for the easy passage of water ions and small particles. And since they have a high permeability, that means that answer choice C low permeability is incorrect about the adaptations in the peritubular capillaries or the reabsorption of various substances. So answer choice C is the correct answer. And we also know that answer choice A is incorrect since it is a true statement because the low blood pressure of the peritubular capillaries allow for the reabsorption and answer choice B is also incorrect since they do have a high protein level, giving us the correct answer, which is answer choice C I hope you found this video to be helpful. Thank you and goodbye.
