Homework Answers
26. C) prevent the heart from expanding and filling properly, therefore restrict the ability of the heart to pump blood
27.a) ventricular contractions
Since ventricular contraction is important for the transport of blood to organs and lung but not the return of blood to atrium
28. D) internal jugular veins
Jugualr vein collects blood from brain and face and deliver to heart
29.a) atriventrucular valve closes
The first s1 sound is due to closure of atrioventricular valve since ventricular pressure exceed atrial pressure
30.b) oxygenated , heart
Pulmonary veins carries oxygenated blood from the lung and deliver to heart
31.b) ventricular repolarization which corresponds with relaxation of ventricular synctyium

Epinephrine causes muscles to contract and the heart and lungs to increase respiration and blood flow. In combination with epinephrine causing glucose production and secretion from the liver, how does epinephrine elicit a system wide response? Multiple Choice A.) Glucose provides energy for muscle contractions, which are stimulate by high concentrations of oxygen. Oxygen is provided by the increase in respiration and blood flow. B.) Glucose provides energy for muscle contractions, resulting in high levels of pyruvic acid. The pyruvic...
