Cardiovascular System Flashcards
Blood
The cardiovascular system consists of the heart, veins, arteries, and capillaries. These components make up two ciculatory systems of blood.
The Systemic and Pulmonary Circulatory Systems
The systemic circulation is the flow of blood throught the body, excluding the_____________ .
Brochial Circulation
The air sacs in the lungs which allow for gas exchange
alveoli
What is the bronchial circulation?
It is the systemic vascular supply to the lung, and it supplies blood to conducting airways down to the level of the terminal bronchioles as well as nerves, lymph nodes, visceral pleura, and the walls of large pulmonary vessels.
True or False? All arteries carry oxygenated blood.
False
The part of the blood circulation that carries oxygenated blood away from the heart, to the body, and returns deoxygenated blood back to the heart.
Systemic Circulation
Blocked arteries, also known as ________, is the build-up of fibrous and fatty material inside the arteries and is the underlying condition that causes corornary heart disease and other circulatory disease.
Atherosclerosis
The _________ is the gas-exchanging tissue of the lung and has a surface area roughly comparable to that of a tennis court.
Parenchyma
Removing carbon dioxide and adding oxygen to the blood occurs due to gas______ _______ gradients across the alveoli of the lungs and the capillaries interwoven in the alveoli.
Partial Pressure
What are the veins that supply the right atrium?
Inferior and Superior Vena Cava, Coronary Sinus, and Azygous Vein
Oxygenated-depleted blood from the body leaves the _________ circulation when enters the right atrium through the superior and inferior venae cavae.
Systemic Circulation
At the lungs, the blod travels through _______ beds on the alveoli
capillary
__________ and ___________ diffuse out of the cell into the blood, while oxygen and glucose in the blood diffuses out of the blood into the cell.
Metabolic Waste, Carbon Dioxide
Systemic circulation keeps the matabolism of every organ and every tissue in the body alive, with the exception of the __________ of the lungs, which are supplied by pulmonary circulation.
parenchyma of the lungs
A myocardial infarction (MI) commonly known as a ______, occurs when blood flow decreases or stops in one of the coronary arteries of the heart.
Heart attack
