catabolism
process of complex nutrients being broken down in to simpler substances and energy is released
cata- “down”
-bol- “to cast”
-ism “a process”
anabolism
process of building up large proteins from small protein pieces (amino acids)
ana- “up”
-bol- “to cast”
-ism “a process”
metabolism
total of the chemical processes in a cell Includes anabolism and catabolism meta- "change" -bol- "to cast" -ism "a process"
karyotype
- picture of chromosomes in the nucleus of a cell
- chromosomes arranged in numerical order to determine their number and structure
histologist
specialist in the study of tissues
endoplasmic reticulum
- network of canals within the cytoplasm of the cell
- large proteins made here from smaller protein pieces
genes
regions of DNA within each chromosome
viscera
internal organs
DNA
- chemical found in each chromosome
- directs activities of cell
epithelial cells
skin cells that cover the outside of the body and line internal surfaces of organs
mitochondria
- provide principal source of energy for cell
- location were ‘catabolism’ occurs
pharynx
throat
- common passage way for food and air
- (Digestive System)
cytoplasm
all material outside nucleus but still inside the cells’ membrane
trachea
wind pipe
- tube leading from throat to bronchial tubes
- (Respiratory System)
cell membrane
- surrounds/protects a cell
- determines what enters/exits
ureters
tubes from the kidneys to the urinary bladder
- (Urinary or Excretory System)
- think: 2 tubes = 2 e’s
nucleus
- control centre of cell
- contains chromosomes
pituitary gland
at the base of the brain
- (Endocrine System)
thyroid gland
surrounds the neck
- (Endocrine System)
cartilage
flexible connective tissue attached to bones at joint
chromosomes
- rod-shaped structures in nucleus
- contains genes
- 46 (23 pairs) in every cell, except egg and sperm cells
adipose tissue
collection of fat cells
diaphragm
- muscle separating abdominal and thoracic cavities
- moves up and down, aiding with breathing
larynx
voice box
- located at the upper part of the trachea
- (Respiratory System)
uterus
womb
- (Female Reproductive System)
urethra
tube from bladder to the outside of the body
- (Urinary or Excretory System)
- think: 1 e = 1 tube
pleura
double-folded membrane surrounding each lung
