During physical stress (e.g., high intensity exercise), describe how the nervous system activates the adrenal medulla compared to the activation of the adrenal cortex. Your answer should include any relevant hormones, regulation of hormone secretion, and their actions.

The diagram shows the pressure in the left ventricle and systemic arteries during two cardiac cycles. The segment “A to B” indicates [first] and label “B” indicates when the [second]

Vasoconstricting the veins would have the most direct effect on which of the following variables?

Describe the three primary processes requiring (i.e., using) adenosine triphosphate (ATP) during the contraction/relaxation of the typical cardiac myocyte.

Which of the following two variables are the most important in determining capillary fluid balance and predicting water movement across the capillary barrier?

During exercise like brisk (i.e., fast paced) walking, the expected changes in CO, TPR, and MAP are:

[first] are hormones secreted from the hypothalamus and [second] are hormones secreted from the anterior pituitary.

Describe how the initiation of a skeletal myocyte contraction is different from the initiation of a ventricular myocyte contraction. Be sure to describe initiating events and also the mechanisms linked to the release of stored calcium in the cell. Include any relevant structures, ions, receptors, channels, organelles or proteins in your answer.

Which of the following would be the best intravenous fluid replacement for a patient that has reduced blood volume due to dehydration?
