describe the difference in blood pressure regulation by sympathetic and parasympathetic stimulation sympathetic: lowers heart rate, lowers cardiac output, lowers blood pressure parasympathetic: raises heat rate, raises stroke volume from higher contractions, raises cardiac output, raises blood pressure. ALSO more vasoconstriction and venous return, so it also raises blood pressure by higher cardiac output 33. describe the hypothalamic negative feedback mechanism cortisol feedbacks negatively to hypothalamus and anterior pituitary 34. Describe the parts of a blastula has a fluid filled center called a blastocoel and has two different cell types, including trophoblasts (placenta) and the inner cell mass(developing organism) 35. describe the relationship between trachea, bronchi, bronchioles, and alveoli trachea is the first one tube that splits into the two mainstem bronchi, and then the bronchi divide into bronchioles, and then end up to alveoli for gas exchange

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
