Histology: Chaper 6- Adipose Tissue
What is adipose tissue and what is its function?
-storage of long-chain fatty acids -regulate metabolism
what does FFAs stand for
Free Fatty Acids
What is the body mass index equation?
Weight (kg)/ Height^2 (in)
High-density lipoprotein (HDL)
good cholesterol
How many calories does 1 gram of fat have?
9
WAT correlates with what system?
Body Mass Index (BMI)
WAP: What is formed after it goes through the Golgi Apparatus?
Chylomicrons
WAT: Function of long-term energy storage
Emulsification and absorption
WAP: After forming the Chylomicrons, where are they absorbed into?
Lacteal
Adipocytes
Large cells with diverse functions that make up Adipose tissue
What are a result of Gallstones?
Reduce the emulsification and absorption of fats
What is leptin?
a hormone that regulates hunger and fat storage
WAT: what is Unilocular?
a single fat droplet
What is leptin produced by?
adipocytes
What is the function Free Fatty Acids (FFAs)?
are mobilized and secreted into circulation
BMI greater than 30 is...
associated with increased health risks
low-density lipoprotein (LDL)
bad cholesterol (adds plaque)
BAT function in the neck?
blood to brain constant temperature
When you lose heat, Leptin...
decreases in energy
What is the meaning behind Emulsification and absorption?
dietary fats are emulsified by bile salts
what is White Adipose Tissue (WAT)?
dietary fats made up of glycerol and 3-Fatty Acid Chains
The WAP distribution in between men and women are
different
What gland does adipose tissue function as?
endocrine gland
BAT function in the kidneys?
functioning kidneys before birth
What is the function of cytokines?
guides the immune response to reduce inflammation
When you gain heat, Leptin...
increases in energy
WAT: The storage and mobilization watches the
intake of dietary fat and the long term energy storage(kcal)
Where are FFAs delivered to?
metabolically active tissues
BAT has more what than WAT?
mitochondrial density
BAT: Multilocular
multiple fat droplets
Where is Brown adipose tissues found?
neck, kidneys, adrenal, and the glands
BAT function in the adrenal glands?
secrete cortisol initiating the stress response
WAT: Where are the WAP absorbed and altered at?
small intestine and Golgi Apparatus
What does leptin stimulate?
the release of cytokines
BAP: What does the deposition and Activation of BAT change with?
the temperature throughout life and with BMI
brown adipose tissue (BAT) is
thermogenic fat that produces heat
Where are adipocytes found in?
under skin (subcutaneous fat)and around organs(visceral fat)
