What is deoxenagated blood is pumped through pulmonary arteries to elastic saclike structures in the lungs called?
Deoxygenated blood is pumped through the pulmonary arteries to the alveoli, which are the small, elastic saclike structures in the lungs. In the alveoli, carbon dioxide is exchanged for oxygen during the process of respiration. This oxygenated blood is then returned to the heart to be circulated throughout the body.

What is the structure and function of elastic arteries?
Elastic arteries are also known as conducting arteries because they carry large volumes of blood away from the heart. They are large vessels with diameters up to 2.5 cm (1 in.) (Figure 21-2). The pulmonary trunk and aorta, as well as their major branches (the pulmonary, common carotid, subclavian, and common iliac arteries), are elastic arteries. The walls of elastic arteries are extremely resilient because the tunica media contains a high density of elastic fibers and relatively few smooth muscle cells.
What blood vessels have elastic quality?
The conducting arteries, which are the high pressure arteries (eg. aorta and pulmonary), are high in elastic fibres. These fibres store energy to help to push blood forward during diastole (heart relaxation).
What has the thickest tunica media?
Large elastic arteries, such as the aorta and pulmonary trunk, have the thickest tunica media. This layer is predominantly composed of smooth muscle cells and elastic fibers, allowing these arteries to expand and recoil in response to changes in blood flow and pressure.
Are coronary arteries elastic?
Yes, arteries have elastic lamina.
Deoxygenated blood is pumped through plomonary arties to elsatic saclike structures in the lungs called?
Deoxygenated blood is pumped through pulmonary arteries to elastic sac-like structures in the lungs called alveoli. These alveoli are where the exchange of carbon dioxide for oxygen takes place during the process of respiration.
Is pulmonary artery an elastic artery?
Yes! It is the only artery that carries deoxygenated blood (other than umbilical arteries in the fetus), it is located close to the heart, where large (conducting) arteries don't have smooth muscles like medium-sized (distributing) arteries have.
The arterioles muscular arteries and elastic arteries are in what position from heart to capillaries?
left ventricle --> elastic arteries (aorta and its larger branches)--> Muscular arteries --> arterioles --> capillaries
Does tunica media of elastic arteries contains more elastic fibers than muscular arteries?
true
What type of blood does artieris carry?
An artery is an elastic blood vessel that transports blood away from the heart. There are two main types of arteries: pulmonary arteries and systemic arteries. Pulmonary arteries carry blood from the heart to the lungs where the blood picks up oxygen. The oxygen rich blood is then returned to the heart via the pulmonary veins. Systemic arteries deliver blood to the rest of the body. The aorta is the main systemic artery and the largest artery of the body. It originates from the heart and branches out into smaller arteries which supply blood to the head region, the heart itself, and the lower regions of the body.
Which blood vessels have elastic fibers?
Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.
What does the term elastic mean pertaining to arteries?
The term Elastic Arteries usually refers to the ability of blood vessels to dilate and constrict freely.
Do muscular arteries branch into arterioles?
Yes blood passes through Elastic Arteries, Muscular Arteries, and then Arterioles.
