Are arteries strong elastic vessels that carry blood to the heart?
yes
Thin-walled blood vessels less elastic than arteries?
aorta
Do muscular arteries maintain blood flow during ventricular diastole?
The structure of the various blood vessels is closely related to their function. The vessels which receive blood from the heart, the elastic arteries, have thick, strong walls to cope with the sudden high pressure produced during diastole; they contain abundant elastic material to allow stretch so that the vessel lumen may accommodate the change of volume. They also have a thick, outer coat of collagenous connective tissue whose tensile strength prevents over-distension of the elastic tissue. The elastic recoil of these elastic arteries is responsible for maintaining a continuous, though decreased, flow of blood to smaller vessels during systole.http://ect.downstate.edu/courseware/histomanual/cardiovascular.html
Does tunica media of elastic arteries contains more elastic fibers than muscular arteries?
true
What type connective tissue is springlike and found in the middle walls of arteries?
Elastic Connective Tissue
Which of the body's blood vessels are the most muscular and elastic?
The body's most muscular and elastic blood vessels are the arteries. They have thick, muscular walls that allow them to withstand and regulate the high pressure of blood pumped from the heart. This muscularity also enables arteries to constrict and dilate, helping to control blood flow. Additionally, the elastic fibers in their walls help accommodate the surge of blood with each heartbeat.
What kind of protein is elastic fibers made of?
Elastic fibers are primarily composed of a protein called elastin, which provides elasticity and resilience to tissues. They also contain microfibrils made of the protein fibrillin, which helps to organize elastin and maintain the structural integrity of elastic fibers. Together, these proteins allow elastic fibers to stretch and recoil, making them essential for the function of various tissues, such as skin, lungs, and blood vessels.
What vessels contain elastic fibers in the walls that are stretched during systole?
Capillaries
What are the different blood vessels?
arteries thick walled and elastic blood vessels capillaries and veins
What is the appearance of elastic fiber?
Elastic fibers appear as thin, wavy, and branching structures within connective tissue. They are composed of the protein elastin and are responsible for providing elasticity and resilience to tissues such as skin, blood vessels, and lungs. Under the microscope, elastic fibers stain dark with specialized stains like Verhoeff's stain.
Why is the dermis elastic and spongy?
The dermis, the layer just below the epidermis, is made up of collagen, elastin fibers, and blood vessels. Together they make your skin spongy and plump.
Strong elastic blood vessels that carry blood away from the heart are?
arteries.
Where Elastic fibers are absent in case of blood vascular system?
The capillaries are the only blood vessels without elastic tissue. This is so that the vessel walls are as thin as possible to reduce the diffusion distance (for gases and waste products). Veins do contain a layer of elastic tissue is their walls, but this is a very thin layer (when compared to arteries).
Why are muscle cells stretchy?
All blood vessels can stretch to an extent. However, arteries are most flexible because they have more muscular fibers in their walls.
Why are blood vessels elastic?
Blood vessels are elastic in order to maintain the circulatory system. The vessels need to be able to stretch based on the force of the blood that is pumped through them. There are also receptors on blood vessels that control the diameter in order to shift blood to other parts of the body.
Are arteries strong elastic vessels that carry blood to the heart?
yes
The second layer surrounding the lumen?
The second layer surrounding the lumen in blood vessels is the tunica media. It is composed of smooth muscle cells and elastic fibers, allowing it to contract and expand to regulate blood flow and pressure.
