Lymphatic System Ch 15

Question 1

The lymphatic System

Answer 1

Part of the Immune system, it returns excess lymph to the blood, traps and filters cellular debris(such as cancer cells and microorganisms), reduces tissue edema by removing fluid from capillary beds and absorbs fats and fat-soluble vitamins from the digestive system and transports them to cells.

Question 2

Lymph/o

Answer 2

Lymph Fluid, lymph vessels and lymph nodes

Question 3

Lymphoid

Answer 3

pertains to lymph or tissue or lymphatic system

Question 4

Interstitial Fluid

Answer 4

The clear colorless tissue fluid that leaves the capillaries and flows in the spaces between the cells of a tissue or an organ (bathes and nourishes cells)

Question 5

Interstitial

Answer 5

Pertains to the spaces in a tissue or organ

Question 6

Lymph

Answer 6

Formed when interstitial fluid moves into the capillaries of the lymphatic system (brings nutrients and hormones to cells and carries waste products from tissue back to the bloodstream)

Question 7

Lymph Capillaries

Answer 7

Thin-walled tubes that carry lymph from the tissue space. (take lymph to lymphatic vessels)

Question 8

Lymphatic Vessels

Answer 8

Similar to veins in that they have valves to prevent the backflow of lymph (unlike blood, lymph only flows in one direction, from its point of origin until it returns to venous circulation - always travels toward the thoracic cavity)

Question 9

Lymph Ducts

Answer 9

Release lymph (and whatever is in the lymph ) into venous blood, where it quickly passed to the lungs and then throughout the body (this can spread infection/diseases)

Question 10

Cisterna Chyli (sihs-ter-nah-ki-lee)

Answer 10

The origin of the thoracic duct and saclike structure for the lymph collection

Question 11

Lacteals

Answer 11

Located in the small intestine, are specialized lymph vessels that transport fats and fat-soluble vitamins.

Question 12

Lymph nodes

Answer 12

Small bean-shaped structures that filter lymph and store B and T lymphocytes. Their primary function is to filter lymph to remove harmful substances such as bacteria and viruses. (swollen lymph nodes often a indication of disease.

Question 13

Mandibular lymph nodes

Answer 13

Lymph nodes located near the mandible

Question 14

Parotid lymph nodes

Answer 14

Lymph nodes located near the ear

Question 15

Para

Answer 15

near

Question 16

otos

Answer 16

ear

Question 17

Mesenteric Lymph nodes

Answer 17

Lymph nodes located near the Mesentery

Question 18

Tonsils

Answer 18

Masses of lymphatic tissue that protect the nose and cranial (upper) throat. Lingual tonsils are located near the tongue, Palatine tonsils located near the palate (roof of mouth), and pharyngeal tonsils are located near the throat

Question 19

Tonsill/o

Answer 19

tonsil

Question 20

Spleen

Answer 20

Organ located near in the cranial abdomen that filters foreign material from the blood, stores erythrocytes, removes damaged or old erythrocytes, and maintains an appropriate balance of cells. (a secondary lymphoid tissue)

Question 21

Sinusoidal lining cells

Answer 21

Where Macrophages line the sinusoids of the spleen. The macrophages phagocytize foreign material, break it down, and present antigenic parts on their surface for the helper T lymphocytes to recognize and initiate and immune response.

Question 22

splen/o

Answer 22

spleen

Question 23

Thymus

Answer 23

A gland that has an immunologic function and is found predominately in young animals, primary role is development of T cells that form and come from the bone marrow. Also has endocrine function

Question 24

Thym/o

Answer 24

Thymus
