The intrinsic rate of the atrioventricular av bundle is 40 to 60 beats per minute (bpm).
<h3>
What is the Atrioventricular (AV) and the intrinsic rate?</h3>
Atrioventricular (AV) can be regarded as the block that usually altered the interruption of impulse transmission between the atria to the ventricles.
And this have the 40 to 60 beats per minute (bpm) as the intrinsic rate.

I believe Tidal volume is the correct answer
The infant's heart rate decreases as they grow and their blood pressure increases. The normal heart rate of infant is at 70 to 190 but as they reaches toddller age it is decreased to 60 to 140. However blood pressure increased as the child grows as blood pressure is quite dependent on size and the weight of the child.
Answer:
E. that area of the membrane is in the absolutely refractory period.
Explanation:
Refractory period is a period during which neuron cell cannot be stimulated (depolarized). This is why the action potential can only travel in one direction from the neuron body towards axon.
Refractory period occurs because of the inactivation of voltage-gated sodium channels (while action potential is at its peak) which cannot be open for a certain period of time. and membrane cannot be depolarized.
<h2>c) option is correct </h2>
Explanation:
- Each synovial joint has a fibrous capsule surrounding the joint, which helps hold the bones together, along with the ligaments (which join bone to bone) and tendons (which join muscle to bone)
- The joint capsule is lined by the synovial membrane, which manufactures the synovial fluid
- The synovial fluid is located within the joint cavity of a synovial joint and has three primary functions: Lubrication
, nutrient distribution and shock absorption
