Answer:
SV = 30 ml/ beat.
HR = 80.
Explanation:
The formula to calculate SV is as follows:
SV = EDV- ESV.
Here EDV = 90ml (end diastolic volume), ESV = 60ml (end systolic volume) ans SV is stroke volume.
SV = 90-60
SV = 30ml/beat.
The formula to calculate HR is as follows:
HR = CO/SV
Here, HR is heart rate, CO is cardiac output = 2,400 ml/min and SV is stroke volume = 30ml/beat
HR = 2,400/30
HR = 80.
Thus, the SV is 30ml/best and HR is 80.
Answer:
1. opening Voltage gated channels
2. Calcium
Explanation:
The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.
The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.
The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.
Thus, opening Voltage gated channels and Calcium is the correct answer.
