komponen :

♣ jantung

♣ pembuluh darah :

–kapiler

–arteri (arteriol – kecil – sedang - besar)

–Vena (venule-vena kecil-sedang- besar)

! Selalu terdapat ENDOTHEL di lapisan dalam (yang berbatasan dengan lumen) Tunica Intima

! Tunica MEDIA berupa otot polos

! Tunica Adventitia berupa j.i. longgar

Vessel nameTunica intima Tunica media tunica adventitia other features

Elastic arteryorConducting artery

Thick Endothelium.thick subendothelial connective tissueporous LEI

elastic fibers and a series of concentrically arranged. Between the elastic laminae are smooth muscle cells, reticular fibers,

connective tissue; vasa vasorum,relatively underdeveloped (thin relative to vessel diameter)

An internal elastic lamina, although present, may not be easily discerned, since it is similar to the elastic laminae of the next layer (that may hard to distinguish, too)

Muscular arteryordistributing artery

Endothelium.The intima have a subendothelial layer

may contain up to 40 layers of smooth muscle cells. These cells are intermingled with various numbers of elastic lamellae (depending on the size of the vessel) as well as reticular fibers

connective tissue; vasa vasorum

The internal elastic lamina is prominent between intima and media. An external elastic lamina is present only in the larger muscular arteries (medium artery)

Arteriole Endothelium. subendothelial layer is very thin

composed of one to five circularly arranged layers of smooth muscle cells; it shows no external elastic lamina

connective tissue; tunica adventitia is very thin.

Capillary Endothelium and pericytes

venule Endothelium, lacks valves

a few smooth muscle cells (very thin)

very thin connective tissue;

Together with arteriole

Medium (and small) vein

Endothelium (fewer valve than in large vein). no LEI.

small bundles of smooth muscle cells intermixed with fewreticular fibers and a delicate network of elastic fibers

connective tissue; vasa vasorum. The collagenous adventitial layer is well developed.

Together with muscular artery

Large vein Endothelium, well developed subendothelial.extension of intima protrude into lumen as valve

few layers of smooth muscle cells and abundant connective tissue (reticular and collagen). Elastin is sparse

The adventitial layer is the thickest and best-developed tunic in veins; it frequently contains longitudinal bundles of smooth muscle

ARTERIOLE

ARTERI KECIL

ARTERI SEDANG

ARTERI BESAR

VENULE

• Ø 0,2 – 1 μm• T.Intima : - endothel tipikal

T. Media : - otot polos [+]- tipis

- T. Adventitia : sangat tipis

VENA (KECIL)

Vasa vasorum - Merupakan pembuluh darah kecil untuk nutrisi arteri/vena dg ø > 1 mm

- berada di Tunica adventitia

Summary• Kapiler : epithel selapis pipih• arteri

– Arteriol : << 5 lapisan epithel– A.kecil : LEI [+]– A.sedang : LEI berkelok, LEE [+]– A.besar : Serabut elastik

• Vena : seperti pasangannya, tapi tipis, kolaps• Jantung : discus intercalatus,,
