Formation And Tissue Fluid And Lymph Flashcards
What is hydrostatic pressure
Water in the plasma being forced out of the fells by the pressure of the hearts contraction
What does hydrostatic pressure take out with it
Dissolved nutrients and oxygen from the haemoglobin in the rbc
What happens to the blood cells and blood proteins because they cannot get pushed through the basement membrane
They get left behind
Tissue fluid must return to the circulatory system otherwise what would happen
Our bodies would swell with the accumulating tissue fluid
What is the condition that could possibly kill where there is an accumulation of tissue fluid
Oedema
Tissue fluid is mostly returnee to the capillaries through what process
Osmosis
What is osmosis
The movement of water through a semi-permeable membrane from a less concentrated soliton to a more concentrated solution
What is osmotic pressure
Water surrounding the tissues , creating an imbalance resulting in water being drawn back into the capillaries by osmosis due to the presence of albumin in the capillaries
As water returns into the capillaries, what does it take with it
Carbon dioxide and other waste products
About 10% of the fluid (lymph)drains into another system, what is this system
The lymphatic system
In the lymphatic system, where does the lymph drain in to
Lymph capillaries, which leads to lymph vessels (which have a similar structure to veins)
Is the lymphatic transport system one way or two
One way
What does the lymphatic system do to maintain correct blood volume
Lymph drains into the main veins after its travelled through the lymphatic system to join the circulatory system at the top of the chest. From the main veins it leads from the arms to the superior vena cava
What are lymph nodes
Swellings
Where do we particularly get lymph nodes
Neck, under arms and groin
