Natural acquired active immunity, you got the disease and you produced antibodies
During the primary immune response, B lymphocytes give rise to plasma cells. (T/F)
True
What defense mechanism responds to the presence of foreign antigens by initiating a cascade of reactions, resulting in inflammation and enhanced phagocytosis in the area
complement system
hepatic duct-
connection liver to the common bile duct, it drains bile from the liver. Transports waste
Chylomicrons transport

greater Umentum is composed of
double layer called parietal membrane
Tissue fluid is formed when fluid___________and lymph is formed when fluid_____________
forced out of the blood plasma, blood capillaries
common bile duct is formed from the
from the hepatic duct from the liver and the cystic duct from the gallbladder
Cholecystokinin stimulates the
gallbladder to contract and release bile into the duodenum
What cells make up the mononuclear phagocytic system
macrophages and monocytes
parotid gland differs from the submandibular and sublingual glands how
parotid gland only consists of serous cells.
How do cytotoxic T cells destroy their targeted cells
perforin
Following contact with its targeted antigen, a B cell will divide and differentiate into_________which produce and secrete antibodies.
plasma cells
Antigen
presenting cells engulf and digest an antigen, then insert antigen fragments on their cell surfaces in association with __Class 2 and makes proteins _
Which of the following occurs during an adaptive immune response?
production of antibodies.
Amino acids can be used for 3 purposes:
protein synthesis to function in various body processes, synthesize proteins for cellular structure and energy
Cholecystokinin regulates
proteins and lipids
The nasal cavity is lined with
pseudostratified ciliated epithelium
functions of the liver
regulates glucose in the blood, secretion of bile, filters the blood, forming glucose from the noncarbohydrates, metabolism formation of urea
What part of an antibody molecule binds to its targeted antigen
the ends of the molecule have light and heavy chain variable regions
secreted by the parietal cells of gastric glands
the parietal cells secrete hydrochloric acid
What occurs during a primary immune response?
the plasma antibody increases slowly peaking at about 10 days after exposure to antigen
What is adiponectin
-a protein hormone secreted by adipose cells that effects the response of target cells to insulin
T lymphocytes are responsible for what aspect of defense against infection
Cellular immune response
AIDS is caused by a virus that targets B lymphocytes (T/F)
False
An immunoglobulin molecule is an antigen secreted by T lymphocytes (T/F)
False
Immune cells called___________are activated when their antigen receptors bind to displayed foreign antigens. They will then release cytokines that function to continue the immune response.
Helper T cells
What type of immunoglobulins are involved in type I hypersensitivity
IgE
Treatment with antibiotic drugs is sometimes followed by a deficiency of vitamin
K
What stimulates the secretion of cholecystokinin from the intestinal wall
Presence of proteins and fats in the small intestine
What is the result of a cellular immune response
T cells attach directly to the cells with the foreign antigens and destroy them
As a result of an allergen binding to an IgE antibody, mast cells release histamine. (T/F)
True
B lymphocytes do not interact with antigen presenting cells. Rather, they target "free" antigens (T/F)

cancer and viral infected
The redness and swelling that occurs with inflammation is due to what changes in the infected/injured tissue
increase of blood flow and increase capillary permeability. Trying to get fluid into area.
What is an effect of the activation of the complement system
increases phagocytosis of an antigen
function of gastrin
