| In comparison with the nervous system, the regulatory effects of the endocrine system are: | Slow to appear but long-lasting. |
| The major hormone produced by the corpus luteum is: | Progesterone. |
| The function of which antibody is basically unknown? | IgD |
| A powerful poison that acts directly on any cell and quickly kills it? | Lymphotoxin |
| Recognition of antigens by antibodies occurs when an | Antibody’s epitopes fit into and bind to an antibody molecule’s antigen-binding site. |

| Which protein interferes with the ability of viruses to cause disease? | Interferon |
| When the pressure in the lung is greater than atmospheric pressure: | Expiration occurs. |
| Molecules formed by the reactions of the complement cascade assemble themselves on the enemy cell’s surface, which results in | Cytolysis |
| If the tidal volume of a given individual is 500 ml, then the anatomical dead space is approximately _____ ml. | 150 |
| The vital capacity is equal to the sum of the: | Inspiratory reserve volume, tidal volume, and expiratory reserve volume. |
| The enterogastric reflex causes: | Inhibition of gastric peristalsis |
| The hormone thought to be a messenger causing release of digestive enzymes from the intestinal mucosa is: | Vasoactive intestinal peptide. |
| The hormone that inhibits gastric muscle, slowing passage of food into the duodenum, is called | Enterogastrone |
| An end product of fat digestion is: | Glycerol. |
| The process of swallowing is known as: | D deglutition |
