Which blood vessels have elastic fibers?
Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.
What type connective tissue is springlike and found in the middle walls of arteries?
Elastic Connective Tissue
How is the structure of arterioles different from that of arteries?
The wall of the arterioles contain less elastic fibers but more smooth muscle cells than that of the aorta and arteries.
Why do veins have less collagen elastic fibers and smooth muscles than arteries?
Because blood in veins is under lower pressure than in arteries, so they do not need as many collagen fibres. In addition, as veins already have a wide diameter, they do not need to dilate that much hence they also dont contract that much (as opposed to artieries), so they have less elastic recoil, thus they have less elastic fibres. :)
What layer of an artery consists mostly of smooth muscle?
Arterial walls are more muscular than the walls of veins. This muscle is smooth involuntary muscle.
Why are the differences in the amount of elastic fibers and smooth muscle fibers in the tunica media of elastic arteries and muscular arteries is important to their function?
The elastic arteries are huge and allow for large amounts of blood to go through them. They need elastic fibers so they can stretch and return to their original state--basically they want to make it easy for large amounts of blood to pass through. Muscular arteries are responsible for getting blood to various locations, so they contract and dilate according to the immediate needs of the tissue they are supplying.
Which blood vessels have elastic fibers?
Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.
Does the dermis contain both elastic and collagen fibers?
yes the dermis contains both elastic and collagen fibers
What is the function of the elastic fibers found in an arterys walls?
Allow arteries to expand
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.
Explain why the wall of the arteries contain numerous elastic fibers?
i don't know ..... !!!!! xP
What type connective tissue is springlike and found in the middle walls of arteries?
Elastic Connective Tissue
How is the structure of arterioles different from that of arteries?
The wall of the arterioles contain less elastic fibers but more smooth muscle cells than that of the aorta and arteries.
What are some connective tissue?
The three types are collagenous fibers, elastic fibers, and reticular fibers. Some examples of collagenous fibers are; tendons, skin, bone, teeth, hyaline cartilage, vitreous humor, the lens of the eye, cartilage, hair, and placenta. Some examples of elastic fibers are found in arteries, veins, and elastic cartilage. Some examples of reticular fibers are found in the meshwork of bone marrow, the liver, and lymphatic system.
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.
Name the 3 types of fibers in areolar connective tissue?
the three basic types of fibers that are found in connective tissue are collagen fibers, elastic fibers, and reticular fibers
What tissue contains loose arrangement of the elastic and collagen fibers?
Reticular layerpapillary layer and reticular layerhave collagenic fibers, however most of abundant area would be the epidermis (as a whole)Unfortunately for them, but fortunately I'm here for you, the answer is Dermis. The dermis is composed of connective tissue containing mainly of collagen fibers and also elastic and reticular fibers. Also, contains connective tissue cells, blood vessels, sweat and sebaceous glands, hair follicles, nail root, nerve endings, and muscular tissues. WE WANT CORRECT ANSWERS ...(ANSWERS.COM) :)
