Open Circulatory System

arterial system is not connected to the venous system through capillary beds

arteries spill onto tissues and eventually finds it's way back to the heart
Closed Circulatory System
some invertebrates but ALL vertebrates

flow of blood is always within the vessels
Precapillary sphincter
regulates the blood flow in the capillary bed by opening and closing
lymphatic system
consists of small open-ended lymphatic capillaries that conduct fluid into larger lymphatic ducts
aortic arch
the curve of the aorta by 180* to the left
from the left ventricle up and down the aortic arch down into the systems

blood is pumped *high pressure*
part of aorta that moves up into the head region
arise from the base of the aorta behind the pulmonary trunk

supplies blood to the cardiac muscle of the heart
pulmonary artery
takes deoxygenated blood from the right ventricle to the lungs
hepatic artery
takes oxygentated blood from the aorta to the liver
renal artery
takes oxygenated blood from the aorta to the kidneys
mesenteric artery
takes oxygenated blood from the aorta to the pancreas, stomach and small intestine
cranial vena cava
vein which carries deoxygenated blood from the five major veins (the internal and external jugular veins) which drain the head and neck
caudal vena cava
takes deoxygenated blood from the body systems to the right atrium.
jugular vein
transfers deoxygenated blood from the head in neck into the cranial vena cava
pulmonary trunk
comes from the right ventrical which then splits into the left and right pulmonary arteries

visible from the lower right to upper left of the heart and passes through the two atria
pulmonary vein
takes oxygenated blood from the lungs to the left atrium
hepatic vein
takes deoxygenated blood from the liver to the caudal vena cava
renal vein
takes deoxygenated blood from the kidneys to the caudal vena cava
umbilical vein
carry oxygenated blood from the placenta to the liver where it is known as the ductus venosus
hepatic portal vessel (function and location)
located between the small intestine and the liver

takes nutrient laden blood from the SI to the liver and then the blood flows to the hepatic vein
ductus arteriosus
in fetal pigs, this is the shunting vessel which connects the pulmonary trunk to the aorta

at birth the shunting vessel constricts and fills with connective tissue
Human Blood Smear
Neutrophils - intestine like nucleus, inflammation process by consuming cell debris and bacteria

Lymphocytes - large glob of nucleus, important in immune response

Erythrocytes - red blood cells, no nucleus, contain hemoglobin (95% of cells in blood)
What is the difference in the vein and artery on the slide?
The artery is surrounded by more muscle layers than is the vein and the vein is larger where the artery is more narrow. The vein also has a one way valve.
