Part four of final exam Flashcards
(24 cards)
Match the hormone/chemical to its function:
__2__
Primes sustenocyte for interacting with testosterone
__4__
Causes increased levels of androgen binding protien
__1__
Causes contraction of the smooth muscle in the female reproductive tracts
__3__
Causes interstitial endocrine cells to synthesize testosterone
__5__
Promotes sperm maturation
- Prostaglandins
- Androgen-binding protein
- Luteinizing hormone
- Follicle stimulating hormone
- Testosterone
Which structure provides endocrine support for a fertilized egg?
corpus luteum
Which structure is the ‘left-over’ non functional ovarian tissue when fertilization does not occur?
corpus albicans
If blood osmolarity is __________ mOsM, the osmoreceptors signal to __________ release of vasopressin.
greater than 280, stimulate
Thirst is
controlled by centers in the hypothalamus and triggered by increased osmolarity.
You ingest a beverage that increases urine output and decreases circulating vasopressin. Which choice best describes how the beverages causes these effects
It contained ethanol and it impaired water reabsorption in the collecting duct
True or False Lipids are absorbed into the blood via capillaries
False
Gastric ulcers treat with proton-pump inhibitors work by:
decreasing the function of the H-K ATPase pump in gastric parietal cells
True or False Proteins are absorbed into the blood via capillaries
True
This chemical causes vasodilation in the penile arterioles and internal pudendal arteries:
Nitric oxide
Place these structures in the correct order starting with the location of sperm production and end with the location of sperm exiting the body during ejaculation
_1__ Testicle
__2__ Vas deferens
__3__ Prostatic Urethra
__4__ Spongy/Penile Urethra
An increase in oxytocin receptor density in the uterus is caused by:
rise in placental estrogens
Dehydration may cause some ions to become concentrated. If a person was suffering from severe hyperkalemia, you would expect
the skeletal muscles to be unresponsive and cardiac arrest could occur.
Aldosterone is a hormone released from the adrenal gland that:
increases potassium secretion & increases sodium reabsorption
You develop a nasty case of rotavirus, thus you have diarrhea and vomiting for 3 straight days (you can’t keep any fluids in you!). Your blood volume and blood pressure are far lower than normal and because it’s diarhhea you also lose a large percentage of the potassium in your blood. Choose all of the following choices that will happen to help restore water homeostasis:
Aldosterone will increase
urine volume will decrease
Angiotensin 2 will increase
ADH will increase
ANP will decrease
Place these steps of lipid digestion and absorption into the correct order
__1__ Lipid globules are emulsified by bile salts
__2__ Lipases digest lipid droplets
__3__ Micelles diffuse across the apical membrane of enterocytes
__4__ Lipids are absorbed into lacteals
From internal to external, order the layers of the stomach
__1__ Lumen
__2__ Mucosa
__3__ Submucosa
__4__ Muscularis externa
__5__ Serosa
Menopause occurs due to:
age-related changes in hormone production and reproductive organ function in females
True or False White and red blood cells freely mix between mom’s and baby’s blood
False
ACE inhibitors
block the conversion of angiotensin I to II.reduce Na+ reabsorption and can decrease extracellular fluid volume.
lower blood pressure.
Which of the following is FALSE about angiotensin II?
activates parasympathetic output
When the plasma concentration of a substance exceeds the maximum transport rate across the renal tubular epithelium, the excess of the substance will be
excreted
True or False In the liver, the central vein carries processed blood away from the liver and boards the inferior vena cava
True
Segmentation:
Mixes the food
