Cardiovascular anatomy lab quiz Flashcards
Pulmonary circulation
Formed by blood vessels that carry blood to and from the lungs; functions only to bring blood into close contact with the alveoli of the lungs so that gasses can be exchanged; Pulmonary arteries carry oxygen-poor, carbon dioxide-rich blood, and pulmonary veins
carry oxygen-rich blood.
Systemic circulation
Provides the functional blood supply to all body tissues. Delivers oxygen, nutrients, and other needed substances while carrying away carbon dioxide and other metabolic wastes
Oxygenated blood
Oxygen-rich, bright-red blood- travels through arteries away from the heart and towards organs in systemic circulation, travels through pulmonary veins to exit pulmonary circulation
Deoxygenated blood
Oxygen-poor, dark-red blood- travels through veins away from organs and towards the heart in the systemic circuit, travels
through the pulmonary artery to enter pulmonary circulation
Venous blood
Blood moving towards the heart
Arterial blood
Blood moving away from the heart
Ductus arteriosus
The fetal circulatory shunt that is most associated with the ligamentum arteriosum and the fetal circulatory shunt most associated with the pulmonary artery; bypasses the nonfunctional lungs
Foramen ovale
The fetal circulatory shunt that is most associated with the interatrial septum- an opening in the interatrial septum that allows
blood to enter the left atrium from the right atrium; bypasses the nonfunctional lungs
Umbilical arteries
The largely deoxygenated blood, laden with metabolic wastes, is delivered back to the capillaries to the placenta; carries
waste-laden blood from the fetus to the placenta
Umbilical vein
Carries freshly oxygenated blood returning from the placenta into the embryonic body; carries oxygen and nutrient rich blood
from the placenta to the fetus
