Circulatory system

An organ system that passes nutrients, gases, hormones, blood cells, etc.

Blood and Lymph

Two types of fluids move through the circulatory system

Lymph, Lymph nodes, lymph vessels.

It forms the lymphatic system

Cardiovascular system and lymphatic system

Collectively make up the circulatory system

Systemic veins

The blood from all parts of the Buddy except that coming from the lungs return to the heart

Two Precaval veins / anterior vena cava

One postcaval vein / posterior vena cava

Three great systemic veins

Sinus venosus

The triangular thin-walled sac into which the precaval and postcaval veins and empty their contained blood

Precaval veins

It extends laterally along the border of the Auricle and then passes through the pleuroperitoneal membrane about 1 cm away from the heart

External jugular veins


External jugular vein

Innominate vein

Subclavian vein

Precaval veins form three tributaries

Mandibular or maxillary Vein

Lingual Vein

Branches of the external Jugular veins

Mandibular or maxillary vein

Lateral branch coming from the angles of the jaws draining blood from the mandibles and also receive blood from the thyroid gland's

Lingual vein

The anterior and median branch draining blood from the tongue, hyoid and floor of the buccal cavity.

Innominate vein

The middle tributary of the precava which receives the small subscapular vein from the shoulder muscle

Internal jugular vein


Two tributaries of the innoniinrermate vein

Internal jugular vein

The junction of the small subscapular vein from the shoulder. It collects blood from the brain and spinal cord the roof of the mouth the muscles nearby and the tissues beneath the parotid gland


The vein from the shoulder muscle

Subclavian vein

The main posterior tributary of the pre-cava which receives two smalls tributaries

Brachial vein

Musculo-cutaneous Vein

Two small tributaries of subclavian vein

Postcaval vein

Follow the vein posteriorly from the sinus venosus to us to the liver

Hepatic veins

Renal veins

Branches of postcaval vein

Hepatic veins

One from the right lobe and the other into the liver

Renal veins

Between the two kidneys from which it receives several renal veins

Hepatic portal system and renal portal system

Two portal systems in the frog

Renal portal vein

A very conspicuous vein along the outer lateral edge of each kidney

Oviducal vein

This is found in a female toad. This are tributaries from the mesovarium or the oviduct which can be identified by tracing the renal portal vein posteriorly

Dorso-Lumbar vein

Two conspicuous veins from the muscle wall come out close to the side of the vertebral column.

-it joins the renal portal vein at above the posterior one fourth level of the kidney and posterior to the kidney and limbs

Femoral vein

It branches from the renal portal vein which is the altar of the two branches which is larger than the inner one.

Sciatic vein

Is the inner branch of the Renal portal vein parallel to the femoral vein.

-this collect the blood mainly from the muscle of the posterior portion of the Thigh

Pelvic vein

The ventral branch of the femoral vein

Ventral abdominal ven

Union of two pelvic veins which runs along the posterior wall of the body cavity towards the median ventral line immediately below the abdominal wall joining the hepatic portal vein at the level of the liver

Ventral abdominal vein

It serves as a connection between the renal and hepatic portal system so that Venous blood from the hindlimbs may return to the heart either by way of the kidneys or by way of the liver

The Hepatic portal system

This system is closely associated with the digestive system

Gastric veins

Coming from the stomach and two in number, one comes from the ventral surface of the stomach, the right gastric vein and left gastric vein.

Pancreatic veins

Receiving blood from the pancreas

Internal carotid Artery

At the point of forking locate a pigmented oval body the Carotid gland

Systemic Arch

This is the middle arch.


Laryngeal artery

The first small branch from the systemic arch which goes to the laryngeal prominence and also supplies to the esophagus

Occipito-vertebral artery

The systemic arch proceeds dorsally and curves posteriorly

Occipital artery

Right at the base where it forks out from vertebral artery, it gives forth a small branch going to the brain passing through the foramen magnum.

Vertebral artery

This artery proceeds alongside the vertebral column on the dorsal parts and supplies branches to the muscle along the vertebral column and to the vertebrae

Subclavian artery

Which goes to the forelimbs to several muscles of the otic region, The inside surface of the abdominal muscles, to the pectoral muscle's and then proceeds to the various muscles of the forelimb proper as the brachial artery

Dorsal Aorta

Follow the systemic arch posteriorly and note the branch that grows out to the nearby region of the esophagus, the esophageal artery

Coeliaco-Mesenteric Artery

A big branch to the digestive organs immediately after the dorsal Aorta

Coeliac Artery

The anterior branch of the coeliaco-mesentery

Intestinal veins

Coming from the small intestines spreading fan-like.

1. Left gastric artery

2. Right gastric artery

3. Hepatic artery

Three branches of coeliac artery

Left gastric artery

Going to the ventral part of the stomach

Right gastric artery

Going to the dorsal side of the stomach and Pancreas

Hepatic artery

Going to the liver and the gall bladder

Anterior mesenteric artery

The posterior branch of the coeliaco mesentery.

Splenic artery / lineal artery

A branch coming from to enter your mesenteric artery he followed by a duodenal branch to the duodenum and continues posteriorly from a distance

Anterior hemorrhoidal artery

A branch from the splenic artery at a distance from the duodenum and then splits into three or four smaller arteries going to the anterior portion of the large intestine

Urogenital artery

Follow the dorsal aorta posteriorly and note the five or six urogenital arteries that supplied the kidneys, flat bodies and the gonads and their ducts.

Lumbar artery

At the region in the kidneys, gonads and ducts, locate the lumbar arteries that go to the dorsal body wall, originating from the dorsal aorta.

Common iliac artery

This artery often close to the forking of the dorsal aorta into the two large common iliac arteries.

Anterior hemorrhoidal vein

Coming from the large intestine

Epogastrico-Vesical Artery

It supplies branches to the muscles of the lateral ventral abdominal wall, urinary bladder and cloaca.

Femoral Artery

A small branch going to the muscles at the base of the thigh

Sciatic artery

Continuation of the femoral artery at the remaining regions of the hindlimb, a large and well develop artery
