Worksheet 11 Flashcards
transport substances in the body of the organism supplying the needs of its metabolism
circulatory system
Provides an effective process of circulations by means of blood, heart, and blood vessels
circulatory system
network of delicate tubes throughout the body
lymphatic system
drains fluid that has leaked from the blood vessels into the tissues and empties it back into the bloodstream via the lymph nodes
lymphatic system
lymphatic system is composed of
lymph
lymph vessels
consist of the heart and a closed system of vessels (arteries, vein, capillaries)
cardivascular system
in frogs, is a three chambered-organ:
heart
a frog’s heart is made up of
2 atria
1 ventricle
the blood is made up of the following
plasma
formed elements
formed elements is made up of
Red blood cells (erythrocytes)
White blood cells (leucocytes)
Platelets (thrombocytes)
red blood cells
erythrocytes
white blood cells
leucocytes
platelets
thrombocytes
Blood vessels are made up of:
veins (deoxygenated blood)
arteries (oxygenated blood
capillaries (smallest, where exchange of gas happen)
carry deoxygenated blood
veins
carry oxygenated blood
arteries
smallest blood vessels, where gas exchange happen
capillaries
the complete separate routes of the blood leading to and from the heart are controlled by these circulations
pulmonary and systemic circuit
his circulation carries blood between the heart and the lungs, particularly its gas exchanging tissues
pulmonary circuit
blood passing through here is returned to the heart via the pulmonary veins
lungs capillaries
exception to the concept of veins carrying deoxygenated blood towards the heart
pulmonary veins
pulmonary veins drain oxygenated blood into what part of the heart
left atrium
exception to the concept of arteries carrying oxygenated blood away from the heart
pulmonary arteries
carries blood between the heart and the other parts of the body
systemic circuit
comprise the arteries and veins
blood vessels
pumps the blood to and from the body
heart
two systems of the blood vessels
arterial system
venous system
difference between veins and arteries in terms of direction of blood flow
vein - towards the heart
arteries - away from the heart
difference between veins and arteries in terms of thickness of walls
vein - thinner
arteries - thicker
difference between veins and arteries in terms of location
vein - superficially located
arteries - deeply imbedded
difference between veins and arteries in terms of nature of blood being carried
vein - unoxygenated
arteries - oxygenated
basically includes the interconnecting of the arteries of the circulatory system that supplies blood
arterial system
site of the conus arteriosus
ventral surface of the heart
where the conus arteriosus bifurcates, also called the ventral aorta
truncus arteriosus
each truncus arteriosus has three branches:
common carotid artery
systemic arch
pulmo-cutaneous artery
describe the pulmonary circuit in ppt
grade yourself accordingly
the anterior branch of the truncus arteriosus that supplies blood into the head
common carotid artery
further divides into external carotid and internal carotid artery
common carotid artery
delivers blood to the muscles of the tongue and floor of the mouth
external carotid artery
the external carotid artery branches off to
muscular artery
thyroid artery
lingual artery
sublingual artery
supplies blood to the upper jaw and cranium, further divided into three major branches:
internal carotid artery
the internal carotid artery divides into three major branches
cerebral artery
lateral perosal artery (stapedial)
ophthalmic artery
provided with many branches supplying the choroid plexus of the brain
cerebral artery
supplies blood towards the ear and extends its branches to the eyelids
lateral perosal (stapedial) artery
lateral perosal artery branches off
temporay artery
mandibular artery
subbranch of lateral perosal (stapedial artery) that supplies blood to the eyelids
temporal artery
subbranch of lateral perosal (stapedial) artery that supplies blood to the roof of the mouth
mandibular artery
branches out to the eye, muscles, and eyelids
ophthalmic artery
extends anterodorsally and posteromedially to unite forming the dorsal aorta and gives rise to the following branches
systemic arch
branch of the systemic arch at the level of the shoulder
subclavian artery
further gives off small branches to the muscles of the shoulder region
subclavian artery
subclavian artery proceeds to the forelimb as this
brachial artery
supplies blood to the larynx and muscles of the jaw
laryngeal artery
supplies blood to the esophagus
esophageal artery
occipital artery anterior branch that supplies into the following:
jaw
orbit
nose
at this region, the dorsal aorta branches off to form a pair of common iliac arteries
pelvic
at the abdominal region, this dorsal aorta branches out to this
common iliac arteries
branches of the dorsal aorta (7)
coeliaco-mesenteric artery
renal arteries
posterior mesenteric artery
oviducal arteries
spermatic artery
ovarian artery
adiposal artery
large unpaired artery that is derived just posterior to the union of the systemic arches,
coeliaco-mesenteric artery
