The vital capacity is equal to the sum of the:

inspiratory reserve volume, tidal volume, and expiratory reserve volume.

Which of the following combinations in arterial blood could cause an increase in the respiratory rate?

Increased PCO2, decreased arterial pressure, decreased pH, decreased PO2

Recognition of antigens by antibodies occurs when an

antigen’s epitopes fit into and bind to an antigen molecule’s antigen-binding site.

During pregnancy, what happens to the oxygenated blood returned from the placenta via the umbilical vein?

It flows into the inferior vena cava.

In comparison with the nervous system, the regulatory effects of the endocrine system are:

slow to appear but long-lasting.

Once inside the sympathetic chain ganglion, the preganglionic fiber may:

synapse with a sympathetic postganglionic neuron. send ascending and/or descending branches through the sympathetic trunk to synapse with postganglionic neurons in other chain ganglia. pass through one or more ganglia without synapsing

A synapse consists of:

a synaptic knob. a synaptic cleft. the plasma membrane of a postsynaptic neuron.
