[@65.23]

wow congratulations any tips for me as that's the grade i'm aiming for

[@tahamuhammad5454]

@@65.23 listen to the teacher in class, try to make notes in class as that's when your memory about the content is the strongest, come back home and watch videos related to the topic(this channel does it the best, but at the end of the day it is your choice).make sure to get a note of all of the keywords(good luck in all of your future exams!)

[@jdufashiondezignz.6715]

Very educative, my Lecturer gave me this link; I have learnt a lot, thank you.

[@maxnguyen3503]

Lots of people think that Professor Dave Explain and Bozeman Science are good but they talk about advnced vocabulary, hard to understand. However, Cognito did it simply in just 5 minutes, explaining everything and make it easier for viewers to understand while Mr. Andersen and Mr. Dave just make it longingly complicated. This video should get more viewers as well as subscribers for this awesome Cognito man.

which part of the body caries both endocrine and the exocrine?? please i wish to know anyone that knows it should help me please thanks i love this video it helped me a lot

[@Cognitoedu]

Hi, the pancreas does both. It secretes hormones like insulin and glucagon into the blood stream (endocrine), but also secretes digestive enzymes into the small intestine (exocrine). Hope that helps!

Thanks Saida. It is negative feedback. Positive feedback is actually very rare in the body.

doesnt the hypothalamus send hormones to the thyroid?

no hypothalamus helps with blood temp regulation because it detects temp of blood
