The tunica intima is the innermost layer containing mostly endothelium, the one through which the lumen runs. Surrounding this is tunica media which mostly muscle tissue. And finally surrounding this is the outermost layer, the tunica adventitia which is mostly connective tissue.
The tunica intima is the inner most layer of the artery. It is made up of a layer of ndothelial cells, supported by th internal elastic lamina. The endothelial cells are actually in direct contact with the blood. The endothelium cells are polygonal, oval, or fusiform, having a vry distinct round or oval nuclei.
1-Tunica intima ( outer layer )
2-Tunica media ( middle layer )
3-Tunica adventitia ( inner layer )
the layers of tissue which the artery is made out of is your mum.
The layers of veins which are made of tissues are called ponaka
the layers of cappiliery is called pani, yerma
These three layers are the endo- (inside) thelium, the meso- (middle) thelium and the epi- (outside) thelium.
Tunica interna, tunica media, and tunica externa.
Mainly, they're made out of the same tissues in the same order, the difference being how thick those tissues are, a lot thicker in arteries than in veins. They're both responsible for blood flow, being the arteries responsible for blood flow from the heart to the tissues and veins responsible for blood flow from the tissues to the heart.
They both cary blood.
They both cary blood.
The three types of blood vessels are the same in both cats and humans: veins, arteries and capillaries.
Blood flows through both Well, for one thing, veins and arteries both carry blood through the body and they both lead from the heart too. The only difference is that the arteries, are fatter than veins. Also, i think that if you pop an artery or poke a hole in your artery, then your blood comes spewing out like a fountain! The arteries take blood from the heart, while the veins, bring blood too the heart.
Like veins of the blood vascular system, the lymphatic collecting vessels have three tunics and are equipped with valvesCarry lymph. Yea varily.Lymphatic vessels need a proper method of transport so they can reach their destination. They are not pumped, but pushed along by skeletal muscle contractions, and valves are in place to prevent fluid from flowing backward. They resemble veins, because the vessels need to be small enough to fit within the body along with the other arteries and veins, which are small enough to be in proximity.
yes
Arteries and veins both carry blood. Arteries are larger and carry blood away from the heart. Veins carry blood to the heart, and they are generally smaller than arteries.
Nothing, it is only pressure that keeps blood moving in the right direction in arteries. Veins have valves that prevent backflow of blood, but arteries do not.
Veins do carry blood to the heart while arteries carry blood away from the heart. Here is a way to remember it: Arteries=Away ( they both have A's in it)
Veins do carry blood to the heart while arteries carry blood away from the heart. Here is a way to remember it: Arteries=Away ( they both have A's in it)
Structural similarities between artries and veins are1) The walls of arteries and veins both contain collagen which makes them strong and durable.2) They both contain elastic fibres which allow them to stretch and recoil.3) Their walls contain smooth muscles that enable them to constrict and dilate.4) They are both three - layered.
