Blood Vessels and Tissues Fluid Revision Carousel Flashcards
Where is hydrostatic pressure created of the blood created?
In the ventricles of the heart
What is oncotic pressure?
The pressure created by the osmotic effects of the solutes
What substances might affect the oncotic pressure of the blood?
Sugars, Proteins, Mineral Ions
State the cell types that are most likely to be found in blood plasma, tissues fluid and lymph.
BP-RBC, neutrophils, lymphocytes
TF-neutrophils
Lymph-lymphocytes
Why can proteins known as plasma proteins not leave the blood plasma?
As they are too large to pass between cells of the capillary wall
Why can neutrophils enter the tissues fluid bu erythrocytes cannot
-Neutrophils can change shape very easily as they have a multi-lobed nucleus and can squeeze themselves between cells
-Erythrocytes can’t change shape as much
Describe the role of the lymph fluid.
Is a system of tubes which returns excess tissue fluid to the blood system
How does tissues fluid facilitate exchange of substance to body cells?
Tissues fluid surrounds body cells so exchange occurs across plasma membranes
