Study Notes
Dogfish Anatomy and Physiology
-
Liver:
- Massive, yellowish bi-lobed gland
- Functions include bile secretion, glycogen storage, fat storage, and destruction of worn out erythrocytes (red blood cells)
-
Pancreas:
- Features a small pancreatic duct running throughout its length
- Duct opens into the intestine, playing a crucial role in digestion
-
Rectal Gland:
- Small, finger-like structure
- Attached by its duct to the dorsal side of the rectum, important for osmoregulation
-
Spleen:
- Large gland with no direct physiological connection to the alimentary canal
- Involved in blood filtration and immune function but not in digestion
