14. Lymphatic System

Question 1

Maintains fluid balance in tissues, absorbs lipids from the small intestine, and defend against pathogens.

Answer 1

Lymphatic System

Question 2

Consist of lymph, lymphocytes, lymphatic vessels, lymph nodes, tonsils, the spleen, and the thymus.

Answer 2

Lymphatic System

Question 3

Are tiny, closed-ended vessels consisting of simple squamous epithelium.

Answer 3

Lymphatic Capillaries

Question 4

Join to form larger vessels resembling small veins. They have beaded appearance because they have one-way valves that are similar to the valves of veins.

Answer 4

Lymphatic Capillaries

Question 5

Three factors which cause compression of the lymphatic vessel.

Answer 5

1. Contraction of surrounding skeletal muscle during activity.
2. Pressure changes in the thorax during breathing.
3. Periodic contraction of smooth muscle in the lymphatic vessel wall

Question 6

Three groups of tonsils

Answer 6

1. Paired Palatine Tonsils
2. Pharyngeal Tonsils
3. Lingual Tonsil

Question 7

Rounded structures, varying from the size of a small seed to a shelled almond.

Answer 7

Lymph Nodes

Question 7

Roughly the size of a clenched first located in the left superior corner of the abdominal cavity.

Answer 7

Spleen

Question 7

A bilobed gland roughly triangular in shape

Answer 7

Thymus

Question 7

Lymphatic capillaries and vessels remove fluid from tissue and absorb lipids from the small intestine, lymph nodes filter lymph, and the spleen filters blood.

Answer 7

Lymphatic System

Question 8

The ability to resist damage from pathogens

Answer 8

Immunity

Question 9

-Called as nonspecific resistance
-body recognizes the pathogens and respond to it but the response is the same when exposed to the same pathogens

Answer 9

Innate Immunity

Question 10

-called as Specific Immunity
-Body respond to pathogens and the response improves each time the pathogen is encountered.

Answer 10

Adaptive Immunity

Question 11

Characteristics of Adaptive Immunity

Answer 11

Specificity (an ability to recognize a particular substance)
Memory (ability to remember previous encounters with a particular substances)

Question 12

Prevent pathogens and chemicals from entering the body.

Answer 12

Physical Barriers (Skin; tears, saliva, and urine.)

Question 13

Most important cellular components of immunity

Answer 13

White Blood Cells (leukocytes)

Question 14

Ingestion and destruction of particles by cells called phagocytes

Answer 14

Phagocytosis

Question 15

An inflammatory response confined to a specific area of the body.

Answer 15

Local Inflammation

Question 16

An inflammatory response that is generally distributed throughout the body.

Answer 16

Systemic Inflammation

Question 17

2 groups of antigens

Answer 17

1. Foreign Antigens
2. Self-antigens

Question 18

-Are proteins produced in response to an antigen.
-Y-shaped molecules

Answer 18

Antibodies

Question 19

an individual is exposed to an antigen and the response of the individual’s own immune system is the cause of the immunity.

Answer 19

Active Immunity

Question 20

occurs when another person or an animal develops immunity and the immunity is transferred to a nonimmune individual.

Answer 20

Passive Immunity

Question 21

contact with the antigen or transfer of antibodies
occurs as part of everyday living and is not deliberate.

Answer 21

Natural Immunity

Question 22

implies that deliberate introduction of an antigen or antibody into the body has occurred.

Answer 22

Artificial Immunity

Question 23

Treats disease by altering immune system function or by directly attacking harmful cells.

Answer 23

Immunotherapy

Question 24

an antigen is deliberately introduced into
an individual to stimulate the immune
system.

Answer 24

Vaccine
