Blood vessels are part of the circulation system in the human body. Blood vessels are like a tube in which blood flows from the heart to the whole body and from the whole body to the heart. If there are problems with the blood vessels, then it is very likely that there will be health problems.
Besides having an important role in blood transportation, blood vessels also contribute to blood pressure control. It's just that controlling blood pressure is not only done by blood vessels, but also supported by a work system that includes signals from the brain and nervous system, hormones, and the natural response of blood vessels.
Recognizing Types of Blood Vessels
Blood vessels consist of five main types. The following are the types of blood vessels and their normal function:Veins
That is a vein that carries blood to the heart. Veins have valves that function to stop the blood from flowing away from the heart.
Venous vessels
Is a collection of capillaries that unite. Venula collects blood from capillaries and drains them into veins.
Capillaries
It is a small vessel with a very thin wall that connects arterioles with venules. Capillary vessels are also called exchange vessels. This is because these vessels can be passed through clean blood which carries oxygen and nutrients to all body tissues and can also receive waste products from body tissues.
Arteriol
Is the artery with the smallest size. The job is to send blood to the capillaries. In addition, arterioles are capable of contraction and relaxation to control the amount of blood entering the capillaries.
Understanding Broken Vessel Disorders
As a result of health problems, blood vessels can rupture and cause bleeding. Here are some of the common ruptured blood vessel conditions:Blood vessels rupture in the skin
When a blood vessel ruptures, the blood comes out of the vessel and enters the body. Chances are you can see blood under the skin layer. This condition can be recognized when pressing the skin on the area, the color will still be red. In fact, normally when the skin is pressed it will leave a white color and gradually red again. Bleeding in the skin can also be caused by allergic reactions, blood infections, injuries, childbirth, side effects of drugs or chemotherapy or radiation, autoimmune disorders, or the normal aging process. However, this condition can also be caused by infections and more serious diseases such as leukemia or blood cancer, meningitis or inflammation of the lining of the brain, or sepsis or inflammation of the whole body due to bacterial infection.
Blood vessels rupture in the eye
One of the bleeding in the eye is subconjunctival bleeding, which occurs when blood vessels under the transparent layer of the eye (conjunctiva) rupture. When you experience this condition, you may not realize it before you can be certain by looking in the mirror, because it usually doesn't hurt. Generally just feels like a scratch and does not change the power of vision. The whites of the eyes will be bright red. The conjunctiva cannot absorb blood quickly, so blood is trapped under this layer. Conditions can be caused by sneezing or coughing too hard, lifting heavy objects, vomiting, or eye injury due to severe infections, rubbing the eyes too rough, or trauma such as foreign bodies injuring the eyes You. Medical conditions such as high blood pressure, blood clotting disorders, diabetes, or consumption of blood-thinning drugs can be risk factors for subconjunctival bleeding. Generally these conditions are harmless and can recover within 1-2 weeks. You may need eye drops, such as artificial tears, to soothe the eyes. If your conjunctival bleeding is repeated, it is recommended to undergo a more detailed medical examination.
Blood vessels burst in the brain
Bleeding in the brain is one of the main causes of stroke. This is due to arteries in the brain rupture, resulting in local bleeding and in the surrounding tissue. This bleeding can cause the death of brain cells. When blood that comes out of a ruptured vessel reaches the brain tissue, the brain will swell because it is filled with blood. This condition increases the pressure around brain tissue and reduces blood flow to the brain, so that brain cells can die. Recovery from this condition depends on the extent of bleeding that occurs and the size of the swelling. Causes of this condition include high blood pressure, head trauma, blood vessel abnormalities, aneurysms, brain tumors, amyloid angiopathy, and liver disease.
