What are the anabolic roles of fats
Give this one a try later!
fats are used as energy storage for future use (triglycerides are used for
this purpose). They are also used to make phospholipids (in cell
membranes), and cholesterol specifically can be used to make steroid
hormones, prostaglandins and bile salts.
What is the main site of absorption?
Give this one a try later!
the breakdown products of digestion will cross through the wall of the
small intestine, enter into either blood capillaries or lymphatic capillaries
,What will happen to the diameter of the afferent arterioles if an increased BP or
increased osmolarity of the filtrate is detected?

GFR is high - then the response is to constrict the afferent arteriole (to
decrease blood volume in there and so get GFR back down to normal)
Name 3 substances that are 100% reabsorbed
Give this one a try later!
glucose, amino acids and small proteins are reabsorbed
What occurs in the esophageal phase of swallowing?
Give this one a try later!
occurs as the food is pushed down the esophagus by peristalsis. It is a
parasympathetic event. When the food approaches the stomach, the
gastroesophageal sphincter relaxes to allow the food into thestomach.
What occurs in the voluntary phase of swallowing?
Give this one a try later!
involves skeletal muscle. It occurs as you place the tip of the tongue
against the hard palate and contract the tongue. This pushes the bolus of
, food into the oropharynx
How do you voluntarily control defecation?
Give this one a try later!
you have voluntary control of the external anal sphincter
What is the role of the following hormones in the female:
Give this one a try later!
GnRH: Hypothalamic Hormone = GnRH - causes the release of FSH and LH
from the anterior pituitary gland.
FSH: Follicle Stimulating Hormone (FSH) - stimulates the eggs to develop
and the follicles on the ovary to mature. FSH also causes the androgens
produced by the ovary to be converted to estrogen.
LH: Luteinizing Hormone (LH) - stimulates the production of androgens
(testosterone) by the ovary. LH also stimulates ovulation estrogen:
Estrogen - stimulates growth of the egg and follicles on the ovary and the
development of the secondary sex characteristics of the female.
androgens: Androgens - stimulate growth of pubic hair and axillary hair and
also stimulates the sex drive
What is the definition of negative nitrogen balance?
Give this one a try later!
, this occurs when you are losing more nitrogen (protein) than you are taking
in
What is the zona pellucid?
Give this one a try later!
The thick membrane around the egg is called the zona pellucida.
When does the fetal phase occur?
Give this one a try later!
2nd and 3rd trimesters
Where are sperm made?
Give this one a try later!
sperm are produced in the seminiferous tubules of the testes
