AN 5.1 Differentiate between blood vascular and lymphatic system

CIRCULATORY SYSTEM = CVS + LS

Difference between Cardiovascular & Lymphatic System

S No	Feature	Cardiovascular System	Lymphatic system
1	Definition	A transport system through which nutrients, hormones, oxygen, other gases and metabolites (waste products) are conveyed to appropriate parts of the body.	A drainage system accessory to the venous system
2	Components	Heart and Blood vessels (Arteries & Veins)	Bone Marrow, Thymus, Spleen, Lymph nodes and Lymph vessels
3	Transporting Fluid	Blood	Lymph
4	Constituent of Transporting Fluid	RBC, WBC, Proteins,	WBCs (esp. Lymphocytes), Proteins
5		Two way	One way (only drainage)
6	Transporting organs	Heart LV, Arteries, Capillaries, Veins, heart RA, heart RV, lungs Heart LA	Interstitial Fluid, Lymph vessel, Lymph nodes , IVC
7	Presence of Valves	Present only in anti gravity Veins	Present
8	Capillary site	In between arteriole and venule	Inter cellular space
9	Capillary permeability	Permeable to small molecules like crystalloids	Permeable to large molecules like colloid material, lipids, microorganisms, cell debris & particulate matter.
10	Valves in Capillaries	Absent	Flap valves are present between endothelial cells
11	Basal lamina in capillaries	Present	Absent
12	Pericytes in capillaries	Present	Absent
13	Function	·      Exchange of gases ·      Excretion of waste products of metabolism ·      Absorption of 85% of the tissue fluid	·      Removes metabolic wastes from the tissue cells ·      Responsible for immune response of our body ·      Absorbs fat from small intestine ·      Accessory drainage system (Absorption of remaining 15% of the tissue fluid)
