Physiology 7-13
| Term | Definition |
|---|---|
| Ingestion | Process of taking food into the mouth, starting it on its journey though the digestive tract. |
| Digestion | A group of processes that break complex nutrients into simpler ones, thus facilitating their absorption; mechanical digestion physically breaks large chunks into small bits; chemical digestion breaks molecules apart. |
| Motility | Movement by the muscular components of the digestive tube, including processes of mechanical digestion; examples include peristalsis and segmentation. |
| Secretion | Release of digestive juices (containing enzymes, acids, bases, mucus, bil, or other products that facilitate digestion); some digestive organs also secret endocrine hormones that regulate digestion or metabolism of nutrients. |
| Gonadocorticoids | Refers to sex hormones that are released from the zone fasciculate and zone reticular of the adrenal cortex rather than the gonads. |
| Glucagon | Produced by the alpha cells, tends to increase blood glucose levels by stimulating the conversion of glycogen to glucose in liver cells. |
| Insulin | Produced by beta cells, tends to promote the movement of glucos, amino acids, and fatty acids out of the blood and into tissue. |
| Artery | Is a vessel that carries blood away from the heart. |
| Capillaries | Are the microscopic vessels that carry blood from arterioles to venues. |
| Vein | Is a vessel that carries blood toward the heart. |
