Circulatory System Flashcards
The pumping organ that delivers blood to the different cells of the body through the blood vessels
Heart
Transport blood from the heart to the different parts of the body
Arteries
Drain blood from the different parts of the body and return it back to the heart for subsequent oxygenation in the lungs
Veins
Separates atria into two chambers
Interatrial/Interauricular septum
An s-shaped longitudinal fold
Spiral valve
Two large vessels divided from the spiral valve
Truncus arteriosus
This circulation carries blood between the heart and the lungs, particularly its gas-exchanging tissues
Pulmonary circuit
These drain oxygenated blood into the left atrium of the heart
Pulmonary veins
This circulation carries blood between the heart and the other parts of the body
Systemic circuit
Give way to the flow of blood which comprise the arteries and veins
Blood vessels
This system basically includes the interconnecting of the arteries of the circulatory system that supplies blood
Arterial system
This is the anterior branch of the truncus arteriosus that supplies blood into the head
Common carotid artery
This delivers blood to the muscles of the tongue and the floor of the mouth through its four major branches such as muscular, thyroid, lingual, and sublingual artery
External carotid artery
This supplies blood to the upper jaw and cranium
Internal carotid artery
This is provided with many branches supplying the choroid plexus of the brain
Cerebral artery
It supplies blood towards the ear and extends its branches to the eyelids as temporal artery and to the roof of the mouth as mandibular artery
Lateral petrosal/stapedial artery
This branches out to the eye, eye muscles and the eyelids
Ophthalmic artery
This extends anterodorsally and posteromedially to unite forming the dorsal aorta
Systemic arch
A branch of the systemic arch at the level of the shoulder. This further gives off small branches to the muscles of the shoulder region
Subclavian artery
This supplies blood to the larynx and muscles of the jaw
Laryngeal artery
This supplies blood to the esophagus
Esophageal artery
This is the anterior branch that supplies blood into the jaw, orbit and nose
Occipital artery
This is the posterior branch that supplies blood to the vertebral column
Vertebral artery
This large unpaired artery is derived just posterior to the union of the systemic arches
Coeliaco-mesenteric artery
This is the anterior branch which gives off smaller vessels such as the left and right gastric artery, hepatic artery and pancreatic artery
Coeliac artery
This branch off into duodenal artery, intestinal artery, splenic artery and haemorrhoidal artery
Anterior mesenteric artery
These are small blood vessels that supply the dorsal surface of the kidneys
Renal arteries
This delivers blood to the large intestine. This unpaired artery specifically supplied the posterior region of the rectum
Posterior mesenteric artery
These deliver blood to the oviduct
Oviducal arteries
These supply blood to the testes and ovaries respectively
Spermatic and ovarian artery
This supplies blood to the corpora adiposa
Adiposal artery
This originates from the ventral wall of the common iliac artery
Epigastrico-vesical artery
This delivers blood to the ventral abdominal wall
Epigastric artery
This delivers blood to rectum and urinary bladder
Recto-vesical artery
It branches posterior to the epigastrico- vesicular artery. This extends dorsally supplying the skin and muscles of the anterior part of the thigh
Femoral artery
It is continuous with common iliac artery and is the major vessel entering the hindlimb
Sciatic artery
This is the posterior branch of the truncus arteriosus
Pulmocutaneous artery
This delivers deoxygenated blood to the lungs
Pulmonary artery
This supplies the skin on the dorsal and lateral body walls. It branches off an auricular artery that supplies the jaw muscles, hyoid muscles and tissues of the lower jaw
Cutaneous artery
This system concentrates on the organization of the veins and all that branch off from it
Venous system
It is the most anterior branch draining into the precava. It is formed by the union of lingual and mandibular veins
External jugular veins
Drains blood from the tongue, hyoid and floor of the mouth
Lingual vein
Drains blood from the lower jaw and thyroid gland
Mandibular/Maxillary vein
This is the middle branch of the vein, which is formed by the union of the internal jugular vein, and subscapular vein
Innominate vein
Accepts many veins draining the palate, brain, orbital, nasal and auditory regions
Internal jugular vein
Collects blood coming from the shoulder and forelimbs
Subscapular vein
This is the posterior branch of the precava
Subclavian vein
Collects blood from the forelimb
Brachial vein
Formed by the union of muscular vein from the dorsal and lateral regions of the body wall and by cutaneous vein from the skin of the body wall
Musculo-cutaneous vein
This comes near the posterior of the kidney as a result of the fusion of a large renal vein. This vein is also the route of the blood that has been collected from certain organs through the capillaries before it returns to the heart
Postcaval vein
It consists of hepatic portal vein and its tributaries: gastric vein, pancreatic vein, splenic vein and intestinal vein
Hepatic portal system
It consists of a large, renal portal vein which is formed by the femoral vein, sciatic vein, dorso-lumbar veins and oviducal vein
Renal portal system
These vessels collect blood exclusively of red blood cells, which seeps through the walls of the capillaries and return it to the veins
Lymphatic system
A series of contractile vesicles where the lymph is pumped throughout the system
Lymph hearts
Receives blood from the left atrium. This then bifurcates to become the truncus arteriosus
Conus arteriosus
A triangular thin-walled sac which accepts blood from the three caval veins
Sinus venosus
