Rearrange these structures in the order in which blood passes through them in a circuit from the heart to the foot and back. Put in order (start with the left ventricle). -abdominal aorta -anterior tibial artery -anterior tibial vein -aortic arch -ascending aorta -common iliac vein -common iliac artery -external iliac artery -external iliac vein -femoral artery -femoral vein -foot -inferior vena cava -popliteal artery -popliteal vein -right atrium -thoracic aorta -left ventricle
Activation of β2-adrenergic receptors in vascular smooth muscle stimulates vasodilation / vasoconstriction. Give an example of organs where this occurs.
A 28-year-old athlete is noted to have a baseline heart rate of 55bpm, which his trainer attributes to excellent parasympathetic (vagal) tone. This parasympathetic effect normally increases Ach release at the SA and AV nodes. Ach release into AV node leads to which of the following effects of its fibers? a. increased action potential amplitudeb. increased conduction velocityc. increased K+ equilibrium potentiald. Hyperpolarizatione. increased rate of depolarization of the pacemaker potential
Using information provided in the text, calculate the power generated by the right ventricle during (a) restful state; blood flow 5 liter/min, and (b) intense activity; blood flow 25 liter/min.
Which of the following statements is true about the SA (sinoatrial) node? a. The action potential created by the pacemaker cells of the SA node directly stimulates the contractile cells of both the atria and ventricles. b. The rate of spontaneous depolarization of nodal cells is the fastest in the SA node. c. Pacemaker cells in the SA node form a pathway between the SA and AV nodes. d. The pacemaker cells, which establish the heart rate, are located only in the SA node.
In patients with congestive heart failure, heart muscles are damaged and weakened (cardiac muscle contractions are weaker). Explain how weaker cardiac muscle contraction will affect cardiac output and why (explain how weaker contractions affect end diastolic ventricular volume, muscle length, stroke volume and cardiac output).

Hello, please answer the following Physiology question completely and correctly. Thank you. Physiology Question: "Draw, both a cardiac muscle action potential and an autorhythmic cell action potential and label the different ion movements.".
Would you please help with the assignment in the attachment?
I need to calculate the approximate heart rate based on the given ECG results, but I can't get how to determine the length of time between two consecutive R waves. What I see, it's one second between the two highest waves (I suppose they are R waves). But it means the heart rate should be 60 beats per minute, but there is no option for this answer. Teach me how to determine correctly the length of time between two consecutive R waves.
