The brain, like every part of the human body, derives its oxygen and nutrients through the the blood that reaches it. This blood is pumped from the heart and travels by way of blood vessels, specifically arteries, to the brain. Waste substances and carbon dioxide are removed from the brain by veins. Although the brain >> Read More ...
Arteries are blood vessels that carry oxygen-rich blood throughout the body. The exception is the pulmonary artery emanating from the right side of the heart which carries oxygen-deficient blood to the lungs for re-oxygenation. Arteries have thicker walls than blood vessels which is muscular and elastic. The muscles allows >> Read More ...
The veins in the leg carry low-oxygen blood laden with wastes and carbon dioxide back to the heart just as do other veins in the body. However, the leg veins are a bit different in structure from veins elsewhere in the body. This is due to the fact that the blood has to return back to the heart against the force of gravity >> Read More ...

When the artery is fully blocked then it is known as renal artery occlusion. As the artery narrows it reduces the blood flow to the kidney and this >> Read More ...
Supraventricular Tachycardia Definition Supraventricular tachycardia (SVT) is a condition where there heart beats rapidly (tachycardia) due to electrical impulses originating the region above the heart’s ventricles, the chambers that push blood of the heart. It is also known as paroxysmal supraventricular tachycardia >> Read More ...
Vertebral Artery Dissection Definition Vertebral artery dissection (VAD) is a condition where blood collects within the walls of the vertebral artery and hampers blood flow through it. Since the vertebral arteries carry oxygen rich blood to the brain, most symptoms are a result of reduced blood flow and oxygen supply to >> Read More ...
What are blood vessels? Blood vessels are the specially designed tubes that carry blood throughout the body. The vessels that carry oxygen-rich blood from the heart to the different areas of the body are known as arteries (singular ~ artery) while those vessels that carry oxygen-deficient blood back to the heart are known >> Read More ...
What is the aorta? The aorta is the artery that carries oxygen-rich blood out of the left ventricle of the heart. As the largest artery in the body, it has many branches which helps to distribute the oxygenated blood to organs and tissues. Typically the aorta starts from the top of the heart (ascending aorta), curves (arch >> Read More ...
What is Milroy Disease? Milroy disease is a condition where there is a problem with lymph drainage and subsequent swelling of the soft tissues (lymphedema) present from birth (congenital). It is a genetic disorder where a mutated gene is inherited from at least one parent but there are instances where there is no known >> Read More ...
