Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.

In resting state: For a heart that would have a left ventricle of 130 mL of end diastolic volume (EDV) and 60 mL of end systolic volume (ESV) and a heart rate 60 bpm. A. Calculate the output your pump should provide to the aortic arch. (in units of L/min) B. In moderate activity state: If the heart rate is expected to increase by 15% Calculate the output your pump should provide to the aortic arch hibernation levels so they can go back to sleep. A mitochondria-rich tissue called "brown fat" is responsible for this heat-generation.
Component Amplitude(mV) Duration (s) P wave 0.046 0.07 QRS complex 0.839 0.08 T wave 0.061 0.2 Describe the physiological events in the heart muscle represented by each ECG component (the P wave, the QRS complex, and T wave). Why does the QRS complex have the largest amplitude?
In a healthy heart during exercise, cardiac output increases as heart rate increases up to about 120bpm, as stroke volume remains constant (CO = HR x SV). As heart rate goes further up, the cardiac output remains stable, and above 160bm it decreases. Why does it decrease? A. shorter filling time decreases stroke volume B. venous return decreases C. valves cannot open and close fast enough D. contractile power of heart muscle cells increases
All the following statements regarding premature ventricular complexes (PVCs) are true except: a. Occasional PVCs may occur in persons without heart disease b. Bursts of two or more PVCs in a row may progress rapidly to ventricular tachycardia €. APVC that falls on or near a T wave may cause ventricular fibrillation d. Frequent PVCs in a patient without heart disease require no treatment
All of the following are correct about the isovolumetric contraction, except ____________. A. This phase of the cardiac cycle begins with the appearance of the QRS complex of the ECG, which represents atrial repolarization and ventricular depolarization B. It represents the time period between the closure of the AV valves and the opening of the aortic and pulmonic valves, ventricular pressure rises rapidly without a change in ventricular volume C. The rate of pressure increase in the ventricles is determined by the rate of contraction of the muscle fibers, which is determine by mechanisms governing excitation-contraction coupling D. Ventricular chamber geometry changes considerably as the heart becomes more spheroid in shape; circumference increases and atrial base-to-apex length increases
Within the T-P interval of the EKG... a. The 2nd heart sound is heard b. the semilunar valves are open c. Ventricular pressure is higher than atrial pressure d. Ventricular cardiomyocytes are relaxed e. L-type calcium current is dominant in the ventricular cardiomyocytes
