How does an increase in heart rate contribute to an increase in blood pressure? O It increases the total peripheral resistance as it increases the amount of blood entering the blood vessels per minute. O It increases the cardiac output as this is solely determined by the heart rate. O It increases the cardiac output, as this is determined by the stroke volume and the heart rate. It reduces the cardiac output, as this is inversely proportional to the heart rate. O It increases the stroke volume as it will cause an increase the force of contraction of the heart.
The force of contraction can be changed by: can choose more than on e Group of answer choices - muscarinic ACh receptors. Activation of the receptors leads to decreased Ca2+ entry and increased K+ entry in ventricles. - Beta2 adrenergic receptors. Increasing cAMP leads to increases in PKA, which increases sarcoplasmic calcium by opening VG Ca+ channels for a longer time, opening SR Ca2+ channels, and increasing the rate of Ca2+ removed by SERCA pumps. - Beta1 adrenergic receptors. Increasing cAMP leads to increases in PKA, which increases sarcoplasmic calcium by opening VG Ca+ channels for a longer time, opening SR Ca2+ channels, and increasing the rate of Ca2+ removed by SERCA pumps. - Not by the parasympathetic NS. (at least, not the ventricles).
Yasmine is a 38-year old woman who is trying to get into working out. Her resting HR is currently 68bpm. Assuming a max HR of 220- age, what percentage of HRmax would the above heart rate zones from question 1 (intensities found for HRR) be for Yasmine?
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
Which of the following are false about the inward rectifier? OA The inward rectifier current is carried by potassium OB. The inward rectifier carries inward current at potentials negative to the Nersnst potential for potassium under voltage clamp conditions. OC. The inward rectifier current obeys Ohm's law. OD.
