1. Aquic moisture regime
A moisture condition associated with a seasonal reducing environment that is virtually free of dissolved oxygen because the soil is saturated by ground water or by water of the capillary fringe as in soils in aquic suborders and aquic subgroups.

2. Aquic moisture regime
A moisture condition associated with a seasonal reducing environment that is virtually free of dissolved oxygen because the soil is saturated by ground water or by water of the capillary fringe as in soils in aquic suborders and aquic subgroups.

3. Arterioles
The smallest arteries; usually branch into a capillary bed .

4. Blood-brain barrier
A barrier made up of neuroglia and capillary walls which limits the movement of substances in the bloodstream into the brain .

5. Capillary
The smallest of the body's blood vessels. Capillaries have walls so thin that oxygen and glucose can pass through them and enter the cells, and waste products such as carbon dioxide can pass back into the blood to be carried away and taken out of the body. Sometimes people who have had diabetes for a long time find that their capillaries become weak, especially those in the kidney and the retina of the eye.

6. Capillary action
The phenomenon of a liquid such as water spontaneously creeping up thin tubes and fibers; this is caused by adhesive and cohesive forces and surface tension.

7. Capillary bed
A branching network of capillaries supplied by arterioles and drained by venules .

8. Capillary electrophoresis
A technique for separating compounds; a sample of a compound to be separated is placed in a capillary tube, which is then subjected to a high voltage current that separates its chemical components.

9. Capillary fringe
A zone immediately above the water table in which water is drawn upward from the water table by capillary action .

10. Cardiac catheterization
This is a procedure involving the introduction of a catheter into the right side or the left side of the heart to study the pressures in the central vein, across the valves of the arteries and the chambers of the heart. The volumes in the cardiac chamber during the cardiac cycle and the patency of the coronary artery are also measured by observing the flow pattern of radiographic dye injected through the catheter. Right heart catheterization measures the right atrial, right ventricular, pulmonary artery and pulmonlary capillary wedge pressures, oxygen saturation, and cardiac output. The catheter is inserted through the femoral vein or subclavian vein. Left heart catheterization measures the aortic and mitral valve stenosis and regurgitations, global and regional left ventricular functions and coronary ateriography. The catheter is inserted through the femoral artery or the brachial artery. Alternative courses of action include: ultrasound, thallium scan, which can give an accurate idea of ventricular function, but neither can demonstrate the degree and location of obstruction of the coronary artery. Material effects, risks and side effects include: allergy to the radiography dye, bleeding, pneumothorax, arrhythmias, air emboli, pulmonary emboli, pulmonary artery rupture and infarction, cerebrovascular accident, myocardial infarction, perforation of the myocardium, infections, sepsis, vasovagal reactions. Local vascular complications at the site of puncture: arterial thrombosis, arterial laceration or dissection, pseudoaneurysm, hematoma, a-v fistula.
