is the perpetuation of species.
Reproduction
such as fission, budding, and
fragmentation where gamete is not involved.
Asexual reproduction
one where male and female
gametes are involved.
Sexual reproduction
These are two hollow lobes with thin walls; they are the
female gonads which produce the egg cells or ova.
Ovaries
The mesentery in the ovary is
called?
mesovarium
These are two slender coiled tubes with fleshy walls close to the middorsal line. These serve as the passageway of ova.
Oviducts
When you trace the oviduct anteriorly the _______, a fringe-like opening is found.
Ostium
is the temporary storage
of the egg cells.
Ovisac or uterus
yellowish finger-like projections at the anterior portion of the kidney and connected to the
ovary.
Corpora adiposa or fat bodies
These contain food reserved to be utilized during the breeding
season.
Fat bodies or corpora adiposa
These are paired yellowish, elongated structures ventrally attached to the kidneys with the mesorchium as mesentery.
Testes
These are tubules lying on the mesorchium connecting the testes to the kidneys. These are also called vas efferens.
Vasa efferentia.
These are also called vas efferens.
Vasa efferentia
These are also the ureters or
mesonephric ducts for the passage of sperm from the kidney to the
cloaca, then the anus.
Vasa deferentia or vas deferens.

about 3 mm to one side of the
median linea alba
truncus arteriosus which looks like a v-shaped structure forks into three:
common carotid artery
pulmo-cutaneous artery
systemic or aortic arch.
is the anterior arch which divides

the internal carotid artery
dilated as carotid gland at its base and dorsal to the posterior roof of the mouth.
internal carotid artery
it also gives off blood to the palatine artery on the roof of the mouth, the
Serebral artery into the cranium to the brain and the ophthalmic artery to the eye

laryngeal artery
Supplies blood to the esophagus
esophageal artery
the occipito-vertebral artery which is further subdivided into?
occipital artery, vertebral artery, subclavian artery,
anterior and supplying blood to
the side of the head and the jaws
the occipital artery
posterior and suppiying blood to the vertebral column
the vertebral artery
supplying blood to the axilla which posteriorly forms the brachial artery
supplying blood to the forearm.
the subclavian artery

Brachial artery
pulmo-cutaneous artery divides into the
Pulmonary and cutaneous artery
supplying blood to the lungs
Pulmonary artery
supplies blood to the skin on the back, the sides of the body and the side of the head.
Cutaneous artery
dorsal aorta gives off to the
coeliaco-masenteric artery,
urogenital arteries, lumbar arteries and posterior mesenteric artery.
The coeliaco-mesenteric artery branches into one celiac artery, the
liver (hepatic artery) and stomach (gastric artery).
