[조직학] 심장순환계의 조직학 (Histology of Cardiovascular System)

1. Circulatory System

1) Blood circulatory system (혈관순환계)
(1) Systemic circulation (체순환)
: heart → systemic arterial system → systemic venous system
(2) Pulmonary circuIation (폐순환)
: heart → pulmonary arterial system →pulmonary venous sysstem
(3) Portal system (문맥계)
: artery나 vein의 경로에 capillary 혹은 venule이 interpose한 것 central pump와는 무관
① venous portal system
a. hepatic portal system
b. hypothalamic-hypophyseal porta1 system
② arterial portal system
: glomerulus-efferent arteriole-peritubular capillay

2) Lymphatic circulatary system (림프순환계)
: tissues → lymphatic vessel (lymph node 통과) → blood circulatory system

2. Systemic blood vessels (체혈관)

1) Tunica intima(내막)
(1) endothelium (내피층): 하루에 1% 교체. basal lamina에 의해 지지
① junctional complexes, pinocytotic vesicles
② blood clotting, vascular smooth muscle tone 조절물질 분비
③ activated endothelium
a. cytokine등에 의해 adhesion mo…
