  • Circulatory system is also known as what?
    Cardiovascular system
  • What are the components of the circulatory system?
    Heart, arteries, capillaries, and veins
  • Heart: pumps the blood through the ARTERIAL SYSTEM under significant PRESSURE.
  • Blood vessels are arranged so that blood delivered from the HEART quickly reaches a network of narrow and thin-walled vessels called CAPILLARIES.
  • What are the layers that surround each chambers of the heart?
    Epicardium, myocardium, and endocardium
  • What is the visceral layer of the serous pericardium?
    Epicardium
  • What layer of the heart adheres to the outer surface of the heart?
    Epicardium
  • What layer of the heart consists of BLOOD VESSELS and NERVES?
    Epicardium
  • What type of epithelial tissues does the EPICARDIUM has?
    Simple squamous mesothelium
  • The simple squamous mesothelium of the epicardium is supported by a layer of what?
    Loose connective tissue
  • Epicardium contains ADIPOSE TISSUE and LUBRICANT FLUID.
  • Pericardial fluid: prevents friction from PERICARDIUM.
  • What is the thickest layer of the heart?
    Myocardium
  • Myocardium is the thickest layer because STRONG FORCE is needed to pump the blood
  • What type of muscle does myocardium has?
    Cardiac muscle
  • The myocardium is thicker in the walls of what chamber?
    Left ventricle
  • What is the INNERMOST LAYER of the heart?
    Endocardium
  • Endocardium consists of what?
    Lining endothelium, connective and smooth muscle
  • Which layer of the heart comprise of the heart's IMPULSE CONDUCTING SYSTEM?
    Endocardium
  • The walls of BLOOD VESSELS except what contain SMOOTH MUSCLE and CONNECTIVE TISSUE in addition to ENDOTHELIAL LINING?

    Capillaries
  • What do you call the specialized epithelium that acts as SEMIPERMEABLE BARRIER between 2 major internal components?
    Endothelium
  • The endothelium separates what two components?
    Blood and interstitial issue
  • What is the outermost layer of blood vessels?
    Tunica adventitia
  • Which layer of the blood vessel composed of LONGITUDINALLY ORIENTED COLLAGEN and ELASTIC CONNECTIVE TISSUE FIBERS?
    Tunica adventitia
  • Tunica adventitia consists primarily of what type of collagen?
    Type I collagen
  • What is the MIDDLE LAYER of the blood vessels?
    Tunica media
  • Which layer of the blood vessels consist of CHIEFLY concentric layers of HELICALLY arranged SMOOTH MUSCLE FIBERS?
    Tunica media
  • What layer of the blood vessels is the INNERMOST?
    Tunica intima
  • What layer of the blood vessels faces the lumen?
    Tunica intima
  • What layer of the blood vessels consist of the ENDOTHELIUM and a THIN LOOSE CONNECTIVE TISSUE?
    Tunica intima
  • What does VASA VASORUM literally means?
    Vessel of the vessel
  • Vasa vasorum: system of vessels that supplies BLOOD to the vascular walls themselves
  • Vasa vasorum is more EXTENSIVE in walls of what type of blood vessels?
    Veins
  • Vasa vasorum is more extensive in walls of veins than arteries due to POOR OXYGEN content of veins.
  • Nervi vasorum: network of AUTONOMIC NERVES that control contraction of the SMOOTH MUSCLE in the vessel walls
  • In the AORTA, which layer of blood vessels REMAIN UNSTAINED?
    Tunica intima
  • In the AORTA, which layer of blood vessels contains MORE ELASTIC FIBERS than smooth muscle?
    Tunica media
  • In the AORTA, which layer of blood vessels occupies MOST of the vessel wall?
    Tunica media
  • In the AORTA, which layer of blood vessels is LESS STAINED and has a narrow peripheral zone of CT?
    Tunica adventitia
  • In the TUNICA MEDIA of the Aorta, which is DARK?
    Elastic fiber
