08/12/13 1. MEDICAL TERMINOLOGY Aneurysm (AN-ū-rizm) A thin‚ weakened section of the wall of an artery or a vein that bulges outward‚ forming a balloonlike sac. Common causes are atherosclerosis‚ syphilis‚ congenital blood vessel defects‚ and trauma. If untreated‚ the aneurysm enlarges and the blood vessel wall becomes so thin that it bursts. The result is massive hemorrhage with shock‚ severe pain‚ stroke‚ or death. Treatment may involve surgery in which the weakened area of the blood

brain. Blood is carried through tube like structures called blood vessels such as the artery and the vein. The arteries carry blood from the heart at high pressure which contains a high concentration of oxygen and nutrients to supply the organs. Veins carry blood at low pressure to the heart which contains a high concentration of carbon dioxide and with a low concentration of oxygen and nutrients. The main artery in the human body is called the aorta which pumps blood at a very high but constant pressure

consists of : heart (심장)‚ and vessels (혈관)‚ arteries (동맥)‚ capillaries (모세혈관) and veins (정맥). A functional cardiovascular system is vital (필수적인) for supplying oxygen and nutrients to tissues and removing wastes from them. Paths of Circulation: Pulmonary(폐의) Circuit : carrying blood to the lungs and back 1. The pulmonary circuit is made up of vessels that convey blood from the right ventricle to the pulmonary arteries to the lungs‚ alveolar capillaries‚ and pulmonary veins leading from the lungs to the left

(areolar and fibrous CT) Picture Generalized Structure of Arteries‚ Veins and Capillaries Types of Blood Vessels Elastic arteries: Contain much elastic tissue Larger arteries closer to the heart Must expand when heart pumps much blood into them and then passively recoil after blood passes by. Thus‚ must withstand pressure fluctuations Muscular arteries: Have less elastic tissue‚ but substantial muscle tissue Smaller arteries farther from heart Exposed to less extreme pressure fluctuations

The right femoral vein is parallel with the femoral artery through the upper thigh and pelvic region. It is one of the larger veins in the body. The femoral vein returns blood into the leg to the heart through the iliac vein. The right femoral vein comes from the abdomen. This vein collects blood from many

cardiovascular system The cardiovascular system is a system that is able to transport things such as nutrients through the body in order for them to reach their destinations. The cardiovascular system is made up of our hearts‚ our blood vessels‚ arteries‚ veins and capillaries and our blood. The system is also linked to the respiratory system. The heart The heart is the size of a closed fist‚ this can be located in the thoracic cavity. The thoracic cavity is a chamber of the body that is between
