ch 3
phospholipids
double lines cell membrane; unique type of lipid that has a water soluble head and a fat soluble tail
enzymes
regulate chemical reactions
cytoplasm
combination of fluid material and organelles within the cell
mitochondria
powerhouse; chemical energy of foods to real energy
nucleus is surrounded by
double membrane
RNA
single stranded nucleic acid involved in transcription of genetic info and translation into protein structures
ribosomes
protein synthesis sites, where amino acids link
endoplasmic reticulum
organelle compound of a network of canals running through the cytoplasm; includes ribosomes
Golgi complex
packing site for lipids and proteins; produced in the cell
secretory vessels
within Golgi complex; contain protein and other compounds to be secreted by the cell
lysosome
cellular organelle containing digestive enzymes
peroxisomes
cellular organelle that destroys toxic products from the cell
catalase
breaks down hydrogen peroxide; protective enzyme
epithelial tissue
composed of cells covering surfaces inside and outside the body; respiratory tract
connective tissue CT
supports and protects the body, stores fat, produces blood cells
muscle tissue
designed for movement
nervous tissue
brain and SC; communication
organ
a group of tissue designed for a function
organ system
collection of organs for a function
anabolic reaction
small molecules to large products; require energy
catabolic reaction
large products to small particles; release energy
lymphatic system
system of vessels and lymph that accept fluids surrounding cells and large particles
lymph
clear fluid; carries forms of fat after small intestine
blood composed of
plasma, rbc, wbc, platelets and more
wbc
immune protection
rbc
o2 and co2
platelets
discs for healing/coaggulation
capillaries
a network of tiny blood vessels
veins
carry blood to heart
arteries
carry blood away from heart
heptic portal circulation
large portal vein carries nutrients rich blood from capillaries to liver
lymph has lots of what
plasma
lacteal
lymphatic vessel that absorbs fat from small intestine
phytochemical are in….
cranberries
ureter
tube from kidney to urinary bladder
neuron
elongated branched cell
neurotransmitter
a chemical signal, compound allowing for communication between cells
serotonin
neurotransmitter regulating mood, sleep, and appetite
where is bile produced
liver
where is bile stored
gallbladder
what must bile absorb and digest
fat
where is icl secreted
stomach
where are nutrients absorbed
SI
probiotics
living organisms that when eaten in adequate amounts, provide health for humans
norepinephrine vs epinephrine
Norepinephrine: More focused on blood pressure regulation and localized neurotransmitter effects.
Epinephrine: More involved in systemic “fight or flight” responses, including energy mobilization and broad physiological effects.
