Microcirculation
Edema
Increases capillary pressure
Right side heart failure
Increases capillary permeability
Local inflammation รั่วมากขึ้น น้ำขังในเยื่อที่ติดเชื้อ
Decrease oncotic pressure
Liver diseases, Nephrotic kidney disease โปรตีนในเลือดต่ำ
Obstruction of lymphatic circulation
Post Mastectomy, Filariasis โรคเท้าช้าง น้ำเหลืองอุดตัน
Structures and components
Venules (Postcapillary venules)
Arterioles
Precapillary sphincters
Metarterioles
Types of capillary
Sinusoidal
Bone marrow
Liver

Continuous
Muscle
Connective tissue
Neural tissue
Fenestrated
Fenestrated
Lymphatic system
Local fluid balance - Returning fluid to the circulatory system
Fat absorption - From small intestine to the circulation
Immune system - Filter and destroy foreign pathogens
Functions of microcirculation
Control of resistance and perfusion
Controlled by
Endothelium
Local metabolites and oxygenation
Local control
Reactive hyperemia
Active hyperemia
Precapillary sphincter – controls perfusion
Arterioles diameter – controls resistance
Capillary exchange
Transcytosis
Large molecules, Proteins
Diffusion
Gas, lipid soluble
Convection
Water transport
