Types of joints
What is a fixed joint
Don't move at all Ex. skull
What are arteries
Carry oxygenated blood away from the heart
What is plasma
Transports nutrients to cells and waste out of cells
90% water 55%blood by volume
what is homozygous
a gene made up of two identical alleles Ex. GG or gg
how is urine excreated
from the kidneys-ureter-bladder until ready -urethra to outside the body
What is a pivot joint
Bones rest on top of each other Allows rotational movement Ex neck and wrist and ankle
What are veins
Carry deoxygenated blood to the heart
What are WBC
Protects against diseases by creating antibodies
large transparent cells
what is heterozygous
a gene made up of two different alleles Ex. Gg or gG
what is the ureter
it sends urine to the bladder about 25cm long
What is a Hinge joint
Allows back and forth rotational movement in one direction Ex knees and elbows
what side of the circut uses deoxygenated blood
the right side takes D.O. blood and brings it to the lungs to get oxygenated
what are platelets
small fragments of blood cells from bone marrow
help with blood clotting and wound repair by creating fibrin nets
what is a genotype
complete genetic code for an individual or a specific trait
what is the bladder
hollow muscular organ with elastic walls that stores urine until released
stores max 1 litre ( person fells at 300-500ml)
What is a ball and socket joint
Allows rotational movement in ant direction Exips and shoulders
what side of the circut uses oxygenated blood
the left side take oxy blood from the lungs and sens it to the rest of the body
What are RBC
transport oxygen from the lungs and carbon dioxide back to the lungs
what is a phenotype
how an individuals trait is expressed
what do nephrons do
they are inside the kidneys and fliter blood
What is a gliding joint
Bones can glide against each other freely Ex hands and feet
order the blood goes through the heart
Superior vena cava-right atrium-right ventricle-pulmany arterie-lungs-pulmany vein-left atrium-left ventricle-aort to the rest of the body
o-,o+,a-,a+,b-,b+,ab-.ab+
dominant vs recessive
if heterozygous dominant trait will always be expressed
if homozygous and two receissive then recessive will be expressed
what do the kidneys do
produce urine by flittering cellular waste and excess water from the blood
