Blood Vessel Blood vessel is the organ that functions carrying blood to come out or come into heart. Human has three blood vessels which are artery, capillary, and vein.
ARTERY • Artery is a vessel that carries blood from the heart. Arteries have thick muscle and elastic. There is one arterial valve, which lies outside the heart. Arteries divided into three kinds, the aorta or large artery which comes from the left ventricle and carries blood containing O2; pulmonary artery comes out of the right ventricle into the lungs and carries blood containing theCO2; arteriole associates with capillaries.
VEIN • Vein is a vessel that carries blood to the heart and have many valves. Veins divided into four kinds, pulmonary vein, superior vena cava, inferior vena cava, and venule. Pulmonary vein is vein from lungs that carry blood-containing O2 towards the left ventricle. Superior vena cava is vein from the upper body part that carries blood toward the right ventricle containing CO,. Inferior vena cava is vein of the lower part of the body that carries blood toward the right atrium containing CO Venule associates with capillaries.
CAPILLARLY • Capillary is the blood vessel that enables interchange of substance between blood and tissue fluid, while vein is the blood vessel that carries the blood back to the heart.
BLOOD CIRCULATION • The un-oxygenated blood come to heart from two veins called Vena Cava Superior (From upper part of the body) and Vena Cava Inferior (From bottom part of the body). • The blood then flow to the right atrium of the heart. The right atrium then flow to right ventricle trough tricuspid valve. • The blood then go to the artery called pulmonary artery trough pulmonary valve. • The blood then go to the lung and re-oxygenated and go back to heart trough pulmonary vein. This is called pulmonary circulation or small circulation. • In the heart blood come to left atrium then go to left ventricle trough mitral valve and then pumped to the body from aortatrough aortic valve. This process called systemic circulation or big circulation. • The aorta send the blood to artery and distributed to other body trough artery which get smaller and smaller and then finally exchange the material it's bring on capillaries then go to the veins. • The vein then finally go back to heart again and the circulation repeated.
BLOOD TYPE • Blood classification system : • ABO • Rhesus (Rh) • Based on presence of agglutinogen (antigen) and agglutinin (antibody). • Agglutinogen is the coagulated substance, while agglutinin is the coagulating substance.
Blood Type in ABO System Blood Type in Rh System
BLOOD TRANSFUSION • Blood transfusion is the process of giving blood from a donor to a recipient. • A donor with O blood type is universal donor. • A recipient with AB blood type is universal recipient.
1st • Hypotension or low blood pressureis the pressure so low it causes symptoms or signs due to the low flow of blood through the arteries and veins. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidney, the organs do not function normally and may be temporarily or permanently damaged. Hypotension is blood pressure that's lower than 90/60 mmHg. • Hypertension or high blood pressure is a condition in which the blood pressure in the arteries is chronically elevated. With every heart beat, the heart pumps blood through the arteries to the rest of the body. Blood pressure is the force of blood that is pushing up against the walls of the blood vessels. If the pressure is too high, the heart has to work harder to pump, and this could lead to organ damage and several illnesses such as heart attack, stroke, heart failure, aneurysm, or renal failure.
Anemia is a disorder caused by the small number of red blood cells or the red blood cells do not have enough hemoglobin. 2nd
Hemophilia is a blood disorder because the blood does not have coagulation factor (AGH or antiglobinehormone), and it is inherited.
Leukemia occurs due to the abnormal increasing of white blood cell quantity, while the amount of red blood cells and thrombocyte decline. Some of the causes are virus • Thalassemia is a genetic blood disorder. People with Thalassemia disease are not able to make enough hemoglobin, which causes severe anemia. Hemoglobin is found in red blood cells and carries oxygen to all parts of the body. When there is not enough hemoglobin in the red blood cells, oxygen cannot get to all parts of the body. Organs then become starved for oxygen and unable to function properly.
3rd • Coronary heart disease is caused by the disturbance of blood flow in coronary blood vessels (arteries and veins that allow blood to flow to and from the heart). • Artherosclerosis is the hardening and degeneration of artery wall due to accumulation of fatty substances, especially cholesterol. • Aneurism is the swelling of blood vessel. • Stroke is a disorder caused by the broken artery toward brain or embolus blocking that makes the brain have oxygen supply deficiency.
