Cardiovascular System
Question | Answer |
---|---|
what is the epicardium made of | simple squamous epithelium on top of areolar tissue |
what is the myocardium made of | cardiomyocytes or cardiac muscle cells |
what is the endocardium made of | simple squamous epithelium on top of areolar tissue |
what is the tunica interna made of | simple squamous endothelium |
what is the tunica media made of | smooth muscle cells + collagen fibers + elastic tissue |
what is the tunica externa made of | areolar tissue + fibroblasts (loose connective tissue) |
epithelium vs endothelium | epi = forms barrier between tissue and outer environment endo = lines the vessel and ensures supple of nutrients |
layers of parietal pericardium | fibrous layer, serous layer |
function of the fibrous layer of the parietal pericardium | anchors the heart in place |
function of the serous layer of the parietal pericardium | reduces friction via production of serous fluid |
function of the pericardia sac | friction reduction, heart anchoring within thoracic cavity, isolation and protection from other thoracic organs |
