BIOS 256 Exam 3 Review Questions with Verified
Correct Answers
what are buffer systems
Minimize shifts in pH, controls body's acid-base level at suitable levels, acids and bases work
together to counter shifts in pH
3 stages of labor and what happens in each
Early/ late dilation- cervix is opening and baby is moving down birth canal.
Expulsion- baby is being born
Placental Stage - placenta is delivered
What is respiratory acidosis?
Occurs when lungs can't move all of the carbon dioxide the body produces. Causes bodily fluid
like blood to become too acidic even over the rate of 45 mm hG then will drop rapidly in order to
compensate.
What are various fluid compartments in the body and where is the most fluid located
intravascular, interstitial, and intracellular. Most is located in intracellular.
Compare and contrast generation of sperm and egg
Both depend on each other for reproduction of human life and undergo meiosis. Sperm develop
in the epididymis while eggs in the ovaries. Egg is bigger than sperm cell. Sperm has tail and is
mobile while egg is oval and immobile.
3 germ layers and structure develops from them
, ectoderm- skin and nervous system
mesoderm- bone, muscle, and connective tissue
endoderm- liver and pancreas
What are 3 hormones coming from either the hypothalamus or anterior pituitary that
affect both male and female system and how
Luteinizing Hormone- Stimulates ovulation in women and testosterone in men
Follicle Stimulating Hormone - Stimulates testes to produce sperm and ovaries to produce
eggs.
Growth Hormone- Maintains healthy muscles and bones and impacts fat distribution
Natriuresis
sodium in urine
Which hormones can change levels of sodium in the blood
aldosterone
What is the pH of blood
7.35-7.45
Where is most of fluid in the human body found
brain and kidneys
intracellular fluid in the cytosol/cytoplasm
