Blood vessels are part of the circulatory system of the human body. Its function is to circulate blood from the heart throughout the body and transport blood from all over the body to the heart. If there is a disturbance in the blood vessels, it is very likely that he alth problems will arise
All of our cells, tissues, and organs need oxygen and nutrients to function properly. If you do not get enough oxygen and nutrients, the body's cells will be damaged and even die. Well, the blood in the body is carried and flowed through the blood vessel system.
In addition, blood vessels also contribute to the regulation of blood pressure. However, blood vessels do not work alone, but also interact with hormones and various organs of the body, such as the nerves and brain, lungs, and kidneys.
5 Types of Blood Vessels
There are five types of blood vessels in the human body, and each type of blood vessel has its own function, namely:
These blood vessels function to bring blood back to the heart. Veins have valves that stop blood from flowing away from the heart. These blood vessels carry dirty blood rich in carbon dioxide to the lungs.
However, of all the veins, there is 1 that functions to carry clean blood from the lungs to the heart, namely the pulmonary vein.
Arteries are responsible for carrying clean blood from the heart to all tissues and organs of the body. Arteries respond to signals from the nervous system to either contract or relax.
When arteries contract, blood pressure generally increases. Conversely, when the arteries relax, blood pressure will decrease. The size of the arteries also varies. Large arteries generally have their own elastic fibers in their walls to help the heart work.
Are the smallest arteries that function to send blood to the capillaries. In addition, arterioles are able to contract and relax to control the amount of blood entering the capillaries.
These are blood vessels that connect between arterioles and venules. With their thin walls, capillaries can help transport nutrients from the blood to the body's tissues.
This is a small vein formed from a collection of capillaries.
Venulae function to collect blood from capillaries and drain it into veins.
Knowing Various Diseases in Blood Vessels
Abnormalities in blood vessels can cause various disorders of the function of organs and body tissues. In general, here are various types of diseases and disorders of the blood vessels that are quite common:
One of the most common blood vessel diseases is atherosclerosis, which is a condition in which hardening and narrowing of the arteries can interfere with blood flow.
When the blockage in the artery is small, this condition usually causes no symptoms. However, when atherosclerosis has caused a large blockage and blood flow is drastically reduced, this can interfere with the performance of the affected organs.
For example, when it occurs in the heart, atherosclerosis can cause coronary heart disease and heart attacks. Meanwhile, if it occurs in the brain, atherosclerosis can cause strokes, especially ischemic strokes.
If it occurs in the arms or legs, blockage of blood vessels can cause peripheral artery disease.
This is a condition when the blood vessels in the skin burst, causing the skin to appear bruised or bruised. Hematomas can be caused by a variety of causes, such as an injury or injury, an autoimmune disease, or a side effect of medications, such as blood-thinning drugs and chemotherapy.
However, in certain cases, easy bruising or bruising can also be caused by cancer, such as leukemia or blood cancer.
This is one of the most common causes of bleeding in the eye. This condition occurs when blood vessels under the transparent layer of the eye (conjunctiva) rupture and make the eye appear red. These complaints generally do not cause pain in the eyes.
Rupture of blood vessels in the eye can be triggered by several things, such as sneezing or coughing too hard, injury to the eye, eye infection, rubbing the eye too harshly, or certain medical conditions, such as high blood pressure and diabetes.
Blood vessel ruptured in brain
When a blood vessel in the brain bursts, a person can have a hemorrhagic stroke. This happens because the rupture of a blood vessel deprives the brain tissue of oxygen, so the brain cannot function properly.
Rupture of blood vessels in the brain can be caused by many things, such as hypertension, severe head injury, brain tumor, aneurysm, or arteriovenous malformation in the brain.
This is a condition when the veins dilate, so that the blood flow in them is disrupted. Varicose veins can appear anywhere on the body, but are most common in the calves and feet. However, in cirrhosis, varicose veins can appear in the esophagus.These varicose veins are called esophageal varices.
Because of its important function, it is important to maintain the he alth of blood vessels at all times.
To prevent various diseases and disorders of the blood vessels, you are encouraged to live a he althy lifestyle, for example by staying away from cigarettes and alcoholic beverages, exercising regularly, and consuming nutritious foods, such as vegetables, fruit, and nuts. a lot of fiber.
You also need to maintain normal cholesterol levels, blood pressure, and body weight to prevent blood vessel diseases, such as atherosclerosis and heart disease.
To ensure the condition of your blood vessels and your general he alth, do regular medical check-ups with your doctor.
If you experience symptoms or disorders of the blood vessels, such as chest pain, cold sweats, frequent tingling sensations, body swelling, or frequent bruising, you should immediately consult a doctor.
This is important so that the doctor can determine the disease or blood vessel disorder you are experiencing and provide the right treatment.
