Video transcript

Hello everyone. Our next question asks which of the following is paired correctly. So three of these are not going to be correct pairing. Only one will be correct. We'll start with choice A scrotum contains the vast difference. Well this is not correct because the scrotum contains the testicles not the vast difference. So we're going to eliminate choice A. That is not correct. Choice B. Says seminal tubules are for sperm production. And yes, that is a correct pairing. I like that. The seminar first tubules um produce, maintain and store the sperm so that is the correct pairing here. But let's keep on going just to talk through our other answers. Choice E says seminal vesicles contains the urine. Um No that's not correct. The seminal bicycle is contains muscular tissue and the purpose of that is to move the seminal fluid and the sperm into the urethra and out the penis so it doesn't contain the urine. It's used to move that seminal fluid in urine. So that is not the correct answer. Choice. D. Says urethra uh connects the vast deferens and testicles. Um That is not correct. The urethra is the tube through which urine and seminal fluid leave the body. So our correct answer here, Choice B. Semi difference tubules and sperm production as the correct pairing. Thanks for watching. See you in the next video
