Term 3 - Tissue Fluid Flashcards
In what part(s) of the body is Tissue Fluid considered Blood Plasma?
In blood vessels (veins, arteries, capillaries)
When does blood plasma turn into tissue fluid?
When blood plasma leaks out of capillaries and is exchanging substances with tissue cells
What is tissue fluid called when it is absorbed by lymph vessels?
Lymph
What direction does lymph travel in lymphatic cells?
Towards the heart
What substances do tissue fluid exchange with body cells?
Gives: Oxygen, Glucose, Nutrients
Gets: Carbon Dioxide, Waste
What does lymphatic cells absorb?
EXCESS Tissue Fluid
What is the term given to blood plasma leaking out of the capillaries due to the force of the movement of blood? (This one’s worded weirdly)
High Pressure Filtration
How does tissue fluid exchange substances with tissue cells?
Diffusion
Describe the difference in levels of Protein between Blood Plasma, Tissue Fluid and Lymph
Blood Plasma - Has more protein (contains large and small molecules)
Tissue Fluid - Has less protein (only the small molecules of protein can leave the capillary wall)
Lymph - same amount as Tissue Fluid (because lymphatic vessels absorb Tissue fluid to become lymph)
Describe the difference in Blood Cells between Blood Plasma, Tissue Fluid and Lymph
Blood Plasma - Has both red and white blood cells
Tissue Fluid - Has only white blood cells (because white blood cells can squeeze themselves out of the capillary wall)
Lymph - No blood cells (because Tissue Fluid blood cells are reabsorbed by capillaries)
Describe the difference in levels of Fat between Blood Plasma, Tissue Fluid and Lymph
Blood Plasma - Lower in fat than lymph
Tissue Fluid - Same as plasma
Lymph - More fat than plasma and tissue fluid (because fat is collected at the small intestine)
