Blood & Lymph Notes• Blood Composition: plasma, red blood cells,
white blood cells, platelets; produced by the red bone marrow.
• Plasma: liquid part; 90% water, 10% nutrients (glucose, fat, vitamins, minerals), waste: “CO2, water vapor”, proteins, chemical messengers.
Red Blood Cells: carries oxygen to body cells; contains hemoglobin (iron protein); lifespan 4 months; if blood bright red, oxygen present, if blood dark red/brown, no oxygen present
Blood & Lymph Notes• White Blood Cells: disease fighting cells; lifespan
months-years; specialized cells• Example:
– Cells: alarm system (T-cells & B-cells)– Cells produce chemicals (antibodies) to fight invasion– Cells that attack the invaders
Immune System (WBC’s)Platelets: clot blood;
produces fibrin protein
White Blood Cells (T cells, B cells): disease fighting cellsred = red blood cellsorange = T cellsgreen = platelets
helper T cell →
← B cell
Blood & Lymph NotesBlood Types: A, B, AB, O;
three allele types: A, B, O
Universal Receiver: AB
Universal Donor: O
Transfusion: transfer of blood from one organism to another organism; if blood clumps, clogs capillaries, results in death
Blood & Lymph Notes• Blood Type: surface molecules found on
red blood cells
• Rh Factor: also surface molecules found on red blood cells– If Rh +, have Rh factor– If RH -, don’t have RH factor
– If Rh- but have received RH+ blood, leads to clumping of blood and death
Rh Factor
Blood & Lymph Notes• Lymphatic (Filtering) System: cleans
and returns fluid to Circulatory System
• Lymph: contains water, glucose, white blood cells
• Lymph Nodes: traps invaders microorganisms (bacteria); node – “filter”
