Why, in physiological terms, does systolic blood pressure increase from rest to exercise and why would diastolic blood pressure remain relatively constant from rest to exercise? Discuss the roles of the nervous system, endocrine, and baroreceptors

release of --------- onto skeletal muscle blood vessles result in ...... 1. Acetylcholine, vasoconstriction 2.norepinephrine,vasoconstriction 3.Acetylcholine, vasolidation  4,norepinephrine, vasolifation    1.can you tell me why do we choose sympathetic instead of para symapthetic. make it short and clear. 2.If we say sympathetic why do we choose pregangolic with ACH ? how can I know? 3. explain how is alpha beta thing relate. How do you choose vasoconstriction vs vasolidation?   please teach me a trick. make it short and claer please. I get so confused

Which formula correctly expresses cardiac output (O) through the end-diastolic volume of the ventricle (V), ejection fraction (E) and heartbeat rate (R)?           O = VER       O = VE/R           O = VR/E       O = RE/V

During vigorous exercise, vasoconstriction occurs in the digestive organs, while vasodilation occurs in the heart. Why would this be beneficial during rigorous exercise?

Given the following values, calculate the fluid movement between capillaries and tissues: hydrostatic pressure of the capillary = 25 mm Hg hydrostatic pressure of the interstitial fluid = 5 mm Hg colloid osmotic pressure of the capillary = 15 mm Hg colloid osmotic pressure of the interstitial fluid = 5 mm Hg Group of answer choices 30 mm Hg into the capillary 30 mm Hg out of the capillary 10 mm Hg into the capillary 10 mm Hg out of the capillary

Activation of β2-adrenergic receptors in vascular smooth muscle stimulates vasodilation / vasoconstriction. Give an example of organs where this occurs.

A general principle of physiology states that information flow between cells, tissues, and organs is an essential feature of homeostasis and allows for integration of physiological processes. How is this principle demonstrated by the relationship between the circulatory and endocrine systems?

Explain how the heart rate, pulse period and pulse amplitude changed with exercise and why?

(please type answer).

Epinephrine is released during vigorous exercise. How would epinephrine cause vasoconstriction in the digestive organs but vasodilation in the heart?
