tissue fluid formation

Question 1

what components make up the blood plasma

Answer 1

• oxygen
• carbon dioxide
• salts
• glucose
• fatty acids
• amino acids
• hormones
• plasma proteins

Question 2

how are capillaries adapted to perform a function

Answer 2

• they have thin walls with pores
• large surface area
• slow blood flow
• short diffusion distance

Question 3

what is tissue fluid

Answer 3

• it bathes all cells
• plasma but without the plasma proteins
• transports oxygen and other nutrients from the blood cells
• transports carbon dioxide into the blood cells
• formed from leakage from capillaries

Question 4

what is lymph

Answer 4

• the remaining tissue fluid that did not get returned to the venule end
• collected and drained via the lymphatic system
• has a similar composition to tissue fluid but contains more lipids and less oxygen

Question 5

what are lymph vessels

Answer 5

• they are blind ended which creates a drainage system
• they only allow fluid to enter
• they return the lymph to the blood stream via the subclavian vein

Question 6

what are lymph nodes

• they are found in the armpit, groin, neck and gut
• they hold many lymphocytes
• intersect bacteria and viruses and help prevent the spread of microbial infection in the body

Question 7

how can having a low number of lipids in the blood affect lymph drainage

Answer 7

• they can affect capillary filtration
• may result in fluid retention
• the lymph vessels can become blocked and swollen
