ventricle
cone-shaped tube arising from the ventricle on its ventral side
conus arteriosus
thin-walled triangular sac on the dorsal side of the heart and is continuous with the right atrium
sinus venosus
wall separating the right from the left atrium
interatrial septum
thin flaps between the atria and ventricle
atrioventricular valves
flaps that open into conus arteriosus
semilunar valves
areas of the venous system
systemic veins, portal veins, pulmonary veins
medial most branch of the precava
external jugular vein
where does medial lingual vein collect blood from
tongue, hyoid and floor of the mouth cavity
where does maxillary or mandibular vein collect blood from
jaws and thyroid glands
precavae is aka
anterior vena cava
external jugular vein divides into two:
medial lingual vein and mandibular or maxillar vein
collects blood from the shoulder and forelimbs
subscapular vein
collects blood from the interior of the skull
internal jugular vein
vein lateral to the first external jugular vein
innominate vein
innominate vein divides to
internal jugular vein and subscapular vein
outermost branch of the precava
subclavian vein
subclavian vein divides to
brachial vein and musculocutaneous vein
divisions of musculocutaneous vein
cutaneous vein, muscular vein
collects blood from the skin of the dorsal and ventrolateral body wall
cutaneous vein
collects blood from the muscles of the same region
muscular vein
large unpaired vein located on the posterior end of the sinus venosus
postacava
collect blood from the dorsal region of the body wall
lumbar veins
vein coming from the stomach
gastric
vein coming from the pancreas
pancreatic
vein from the spleen
splenic
vein from the small and large intestine
intestinal
collects blood from the oviduct
oviducal vein
collects blood from the anterior and dorsal side of the thigh
femoral vein
collects blood from the posterior side of the thigh
sciatic vein
collects blood from the urinary bladder
vesicular vein
connected to the left and right femoral veins are the
pelvic veins
pelvic veins unite and connects to the
anterior abdominal vein
location of the anterior abdominal vein
beneath the linea alba
supply oxygenated blood to different parts of the body
arteries, except pulmonary artery
lingual artery or external carotid artery supplies blood to
supplies blood to the thyroid gland, muscles of the hyoid apparatus, tongue
supplying blood to the roof of the oral cavity
palatine artery
supplies blood to the brain
cerebral artery
supplies blood to the eyes
ophthalmic artery
middle branch of the truncus arteriosus
systemic arch
supplies blood to the larynx and jaw
laryngeal artery
supplies blood to the esophagus
esophageal artery
supplies blood to the orbit and nose
occipital artery
supplies blood to the vertebral column
posterior vertebral artery
kidneys are made up of
nephrons
functional unit of kidneys
nephrons
function of kidneys
regulate number of ions inside body of an animal, remove waste products of metabolism from body and to make urine
principal organs of reproductive system
paired gonads - testis and ovaries
composition of nephrons
renal corpuscle, renal tubule
composition of renal corpuscle
glomerulus enclosed by Bowman’s capsule
composition of glomerulus
capillaries
renal tubule function
where the liquid or blood that has been filtered by the glomerulus will flow, and where urine is produced
renal tubule are lined with what type of epithelium
simple cuboidal
seminiferous tubules of the testis is lined by
germinal epithelium
mature sperm cells
spermatozoa
parent cells of mature sperm cells
spermatogonia
spermatogonia give rise to spermatozoa via what process
meiosis
where is spermatogonia found
cysts
primary oocyte eventually becomes
mature oocyte
explain process of spermatin production
spermatogonia will undergo mitotic division, producing primary spermatocytes, these will undergo meiosis to form secondary spermatocytes which grow into spermatids
nucleus of the oocyte is referred to as
germinal vesicle
role of nucleoli inside the germinal vesicle of oocyte
play a role in yolk distribution of growing oocyte
follicle cells
covering the cell membrane of oocytes and provide nourishment to the growing oocyte
enclosing the follicle cells
theca interna or cyst wall
where is theca interna absent
at the region of future rupture during ovulation
function of mesonephric ducts
collect the urine from the kidneys
mesonephric ducts is aka
Wolffian ducts
TRUE OR FALSE: mesonephric ducts only serve as passageway for urine
False, it also serves as passageway for gametes
if mesonephric ducts function for the passage of spermatazoa they are called
vas deferens
function of bladder
temporarily store urine before the cloaca opens
testis are held in place by
mesorchium
vas efferentia
tube that is connected to the testis that facilitates the transfer of mature sperm from testis to kidney
fat bodies is aka
corpora adiposa
ovaries are suspend by
mesovarium
oviducts is aka
Muellerian ducts
function of ostium in oviducts
serves as entrance of eggs released by ovary into the coelom
posterior enlargement of the oviduct
uterine enlargement
function of uterine enlargement
stores eggs temporarily
differentiate right and left atrium
right - receive blood from sinus venosus
left - receive oxygenated blood from lungs pulmonary vein
function of ventricle
pumps blood out of the heart to the lungs via the pulmonary artery and other parts of the body via the conus arteriosus
function of spiral valve
separates blood that will be sent to systemic and pulmonary circulations
subclavian artery extends laterally and becomes the
brachial artery
supplies blood to the forelimbs/anterior ribs
subclavian artery
supplies blood to the left side of the stomach and left side of the pancreas
left gastric artery
supplies blood to the liver and portions of pancreas
hepatic artery
go to the rest of the pancreas
pancreatic arteries
supplying blood to the spleen
splenic artery
supplying blood to the small intestine
intestinal arteries
supplying blood to the large intestine and cloaca
anterior hemorrhoidal artery
branches of dorsal aorta going to kidneys
renal arteries
supplies blood to testes
spermatic arteries
supplies blood to ovaries for females
ovarian arteries
supplies blood to adipose tissues
adiposal arteries
supplies blood to dorsal wall
lumbar arteries
artery branch that goes to the oviduct
oviducal arteries
supplies blood to abdominal wall
epigastric artery
supplies blood to cloaca and urinary bladder
rectovesical artery
supplies blood to the muscles and anterior part of the thigh
femoral artery
supplies blood to the lowermost part of the hindlimb
sciatic artery
divisions of pulmocutaneous artery
pulmonary artery, cutaneous artery
supplies blood to lower jaw
auricularis artery
supplies blood to dorsal part of skin
dorsalis artery
supplies blood to lateral part of the skin
