animal reproduction
what form of asexual reproduction associated with the break off a segment or fragment to reproduce?
where does spermatogenesis take place?
seminefarious tubules
where does fertilization takes place?
Fallopian Tube
what is the a natural killer T-cell?
Nonadherent lymphocyte cells that bind to all aberrant target cells killing them. They have promiscuous binding thus they are nonspecific.
(binds and kills the target cells directly using promiscuous binding[using promiscuous receptor]. Also a form of nonspecific immunity.)
True or false: t-cells decrease the through age.
true
what type of organism contains both male and female reproductive parts( ova and sperm)?
Hermaphrodite
where does the sperm mature?
in the Epididymis
what result from the combining of ova and sperm?
zygote
what is so special about Pattern Recognition or Toll-like Receptors function?
Receptors on phagocytic cells that bind molecules that are unique to microorganisms. Binding allows the cells to easily ingest the microorganism.
which of the following is not MALT( mucosal associated lymphoid tissue)?
A. BALT
B. SALT
C. GALT
D. UGALT
B. SALT( what is the "S"):/
True or False: Internal fertilization has higher survival rate.
True
how does the cell process move?
diploid to haploid
what results from the gastrulation?
endoderm
ectoderm
mesoderm
Provide an example of artificial immunity.
Any example anything that involves syringe or injection into the circulation
examples: Immunization, vaccine
immuniaization is based on what?
making memory cells
what type of animal development occurs in all chickens?
Oviparous
what is the function of the acrosome?
harden the corona radiata after penetrating the egg.
True or False: Mother blood is mixed with the baby's blood.
False
Provide a example/scenario of natural immunity.
( you go through the process and survive)
You are exposed to a pathogen, you get a disease, you recover, you are immune, but you could die from the disease
what is IgG?
what is IgA?
IgG is immunogobulin that is transferred from the Mom to child for nonspecific immunity through the placenta
IgA is immunogobulin that transferred through the breastmilk.
what part of immune system exposure causes tissue damage or negative effect in the organism.( where pathology occurs)
disease
name the steps of white blood cells infiltration into the tissue.
1. Capillary dilation
2. Rolling leukocytes
3. Adhesion/margination
4. Diapedesis
5. Chemotaxis
name 3 forms of endocytosis and describe what each ingests:
Punishment: sing Baby shark
phagocytosis: ingests particles
pinocytosis: ingest soluble
receptor mediated endocytosis: ingests anything that binds to its receptor
How does the primary cells make antibody?
APCs => Tcell=>th0=>th2=>b-cell=>plasma cell=> makes Ab
what word means "ready to eat" in the immune system?
oppsonization
