invasive treatment in which our doctor uses heat to remove varicose veins. The heat cauterizes and closes the varicose veins in the legs so that they gradually dry up and disappear. Varicose veins are the result of poor blood circulation usually from the legs back to the heart. This condition is called venous insufficiency and occurs when the valves in the veins become weak and do not help push the blood along. The blood pools in the veins causing them to become swollen and look bulging and twisted. They

Capillaries exchange fluids‚ gasses‚ heat‚ nutrients and wastes to the tissues through diffusion. Capillary walls contain small pores that are selectively permeable allowing only certain molecules to pass in and out. This exchange is controlled by blood pressure through hydrostatic pressure and osmotic pressure. Osmotic pressure is produced by high levels and salts and proteins in the blood. As blood enters the capillary by the arteriole end the blood pressure is higher than the osmotic pressure

There is a thin wall between the atria’s that is called the interatrial septum. There is a wall between the ventricles called interventricular septum. Right Atrium- This is the superior right chamber. It receives deoxygenated blood from the main veins‚ the superior and inferior vena cava and the coronary sinus. (These veins drain a series of blood vessels called the systemic circuit

increase in the pressure within the portal vein or one of its branches. Typical portal vein pressure is 5 to 10 millimeters of mercury (abbreviated mmHg). When the pressure exceeds 5 mmHg above inferior vena cava pressure‚ it is characterized as portal hypertension. The portal vein carries nutrient rich blood from the digestive system to the liver. Normally‚ the veins come from the stomach‚ intestine‚ spleen‚ and pancreas. They merge into the portal vein‚ which then branches into smaller vessels and

this. A useful method for obtaining a blood sample for the beginning veterinary technician is to draw it from the cephalic vein. I am going to explain the process of taking blood from a dog’s cephalic vein which is located in the canine’s forelimb‚ known as canine venipuncture. Canine venipuncture is a fairly simple process. When drawing a blood sample form the cephalic vein you will need several things on hand‚ including a veterinary assistant to restrain the animal. The supplies needed are a
