Chapter 2 (Section D) Flashcards
works in conjunction with the circulatory and immune systems to prevent disease and maintain fluid balance
lymphatic system
filter and remove foreign particles from circulation in the body
lymph nodes
consume foreign bodies within the lymphatic system
lymphocytes
interstitial space
space between cells
system responsible for breathing, oxygen supply and gas exchange at a cellular level
Respiratory System
the exchange of gasses between blood and tissues
internal respiration
the use of oxygen within cells for specific activities
cellular metabolism
what is breathing controlled by
the autonomic nervous system
ventilation
breathing (inhaling and exhaling)
Two systems that cooperate with the respiratory system to make ventilation possible
nervous and muscular systems
Direction of diaphragm during inhale and exhale
o-downward/x-upward
produces, releases, and controls hormones
endocrine system
What do hormones affect?
growth, development, and metabolic activity
Two main categories of endocrine system glands
exocrine and endocrine
Urinary system functions
(2)
excretes metabolic waste and maintains internal fluid levels
Urinary system organs
kidneys, ureters, bladder and urethra
How much blood and fluid do the kidneys filter?
200 quarts daily; some is reabsorbed and some is excreted via the urinary bladder
What do the kidneys do?
(3 functions) WAW
remove waste, excess ammonia, and excess water from the body
Major functions of the reproductive system
(4)
produce sperm and ova, transport and sustain sperm and ova, grow and develop offspring, produce sex hormones
Primary organs of the reproductive system
ovaries and testes (gonads)
produce gametes (sex cells) and sex hormones
Gonads
have ducts that carry secretions to the surface; include sweat and mammary glands
exocrine glands
ductless glands with secretions moving directly into the bloodstream
endocrine glands
