What is the normal pH of human blood?
Answer: 7.35–7.45
Normal human blood pH ranges from 7.35 to 7.45; deviations cause acidosis or alkalosis, disrupting metabolic processes.
Which part of the brain regulates body temperature, hunger, and thirst?
Answer: Hypothalamus
The hypothalamus is the master regulator of homeostasis, controlling body temperature, hunger, thirst, and circadian rhythms.
How many chambers does the human heart have?
Answer: 4
The human heart has four chambers: two upper atria (left and right) and two lower ventricles (left and right).
Which part of the neuron transmits nerve impulses away from the cell body?
Answer: Axon
The axon carries nerve impulses (action potentials) away from the neuron's cell body toward the axon terminals.
What is the approximate total lung capacity in a healthy adult?
Answer: 6 liters
The total lung capacity of a healthy adult is approximately 6 liters, consisting of tidal volume, reserve volumes, and residual volume.
What is the resting membrane potential of a typical neuron?
Answer: -70 mV
The resting membrane potential of a neuron is approximately -70 mV, maintained by Na+/K+ ATPase pumps and ion channel permeability.
