test study Flashcards
system responsible for blood movement
circulatory system
the heart serves as a
pump
arteries and veins are the
highways
capillaries are the
side streets
relate the circulatory to vehicular travel
it is like a highway where cars drive on and the blood is the cars
refers to lung circuit
pulmonary
refers to the rest of the body
systemic
carry blood away from the heart
arteries
carry blood to the heart
veins
how many chambers does the heart have
4
2 chambers that receive incoming blood
atria
2 chambers that pump outgoing blood
ventricles
protective sack around the heart
pericardium
muscular wall of the heart
myocardium
muscular wall that separates the sides of the heart and prevents oxygen-rich blood from mixing with oxygen-poor blood
septum
carries oxygen-rich blood from the left ventricle to the body
aorda
brings oxygen-poor from the upper right body to the right atrium
Superior Vena cavity
accepts oxygen -poor blood from from the body
right atrium
pumps oxygen-poor blood into the lungs
right ventricle
brings oxygen-poor blood from the lower body to the right atrium
inferior vena cavity
carry oxygen-poor blood to the lungs
pulmonary arteries
accepts oxygen-rich blood from the lungs
left atrium
bring oxygen-rich blood from the left lung to the left atrium
left pulmonary veins
pumps oxygen-rich blood to the body
left ventricle
what is the average resting heart rate
72 bpm
how much blood does the heart pump per minute
70 ml
veins that are caused by weakened vessel walls as a result of inactivity
varicose veins
healthy blood pressure
120/80
unhealthy blood pressure
140/90
when plaque builds up on the walls of blood vessels
atherosclerosis
result of a clot breaking free and restricting blood flow to the brain
stroke
period of rapid growth and sexual maturing
puberty
follicle stimulating hormone
FSH
leutinizing hormone
LH
location of sperm production
seminiferous tubules
storage spot for sperm
epididymis
combination of seminal fluid and sperm protects sperm from vaginal acidity
semen
how much sperm is present in 1 ml of semen
50-100 million
how many eggs are produced per month
one
how many ova are released in a lifetime
400
act of releasing an egg
ovulation
point at which females no longer release ova
menopause
link ovaries to the uterus
fallopian tubes
location of zygote development
uterus
fertilization
when the penis reaches the cervix which is where semen enters
where does fertilization occur
fallopian tube
64-cell solid ball
morula
hollow center mass that implants to the uterine wall in a process called implantation
blastocyst
begins at this point which is when cells first begin to specialize
differentation
location for fetal development and provides nutrition and waste removal
placenta
