Majors animal: Anatomy of a liver fluke (matching)
| Structure | Function |
|---|---|
| Oral sucker | Specialized for attachment to host; used in feeding |
| Ventral sucker | Secondary point of attachment to host |
| Pharynx | Muscular tube for pumping in blood and body fluids from host |
| Gastrovascular cavity | Forked tube for digestion and distribution of nutrients throughout body (reduced in flukes) |
| Testes | Produce sperm |
| Vas deferens | Stores sperm and moves it to genital pore |
| Genital pore | Receives sperm and moves it to the seminal receptacle |
| Ovary | Produce ova |
| Seminal receptacle | Receives sperm and stores it (often for the life of the fluke) eventually moving sit to the uterus where ova are fertilized |
| Yolk gland and yolk duct | Ova are combined with yolk and shelled before passing to the uterus |
| Uterus | Shelled, fertilized ova are stored here until release through the genital pore |
| Excretory canals and ladder | Collect metabolic waste from the flame cells |
| Excretory pore | Releases metabolic waste products out of the body |
