what is blood considered as
specialized connective tissue because it is made up of a group of cells that preforms specific function
3 components of blood
where are blood cells produced
bone marrow
what is the process of blood cells being made called
hematopoiesis
functions of blood
transportation, regulation, and protection
Function: Transportation
-O2 from lungs to cells of the body
- CO2 from cells to lungs
- nutrients from digestive system to cell
transporting hormones from endocrine glands to organs
Function: Regulation
Function: Protection
plasma
3 types of protein found in plasma
albumins
maintains blood pressure and volume
fibrinogen
important for forming blood clots
globulins
transport proteins around the body
( some are antibodies )
what are the two types of blood cells
Red blood cells
( erythrocytes )
- flattened discs with con-caved center
-ideal for gas exchange
- no nucleus
- no organelles
- live 120 days
hemoglobin
-within RBCs
- contains Iron and when bound to O2 it becomes a brighter red
why is having no nucleus important for RBCs
main function of RBCs
to transport respiratory gases
White blood cells
( Leukocytes)
- spherical but has the ability to change shape
- has a nucleus and organelles
- bigger than RBCs
Main function of WBCs
to protect the body by fighting foreign invaders and infections
most abundant to least abundant WBCs
Neutrophill, Lymphocyte, monocyte, eosinophil, and basophil
( never let monkeys eat bananas )
Most WBCs go through
amoeboid, phagocytosis, and chemical properties
Amoeboid action for WBCs
Phagocytosis
can eat bacteria and toxins
- breaks down pathogens within the lysosome of the cell
