Lymphatic System

Question 1

The lymphatic system consists of a network of

Answer 1

Capillaries
Vessels
Nodes
Glands
Organs

Question 2

Spleen function

Answer 2

Removes old blood cells

Question 3

Thymus function

Answer 3

Where T lymphocytes (T-cells) mature

Question 4

Red bone marrow generates

Answer 4

Lymphocytes

Question 5

Tonsils and adenoids filter

Answer 5

Bacteria and viruses

Question 6

Lymphatic capillaries function

Answer 6

Between cells, these closed-end capillaries drain extracellular fluid

Question 7

Lymphatic vessels function

Answer 7

Thin tubes shaped like blood vessels that carry lymph fluid and white blood cells through lymph nodes within the lymphatic system

Question 8

Lymphatic tissue function

Answer 8

Lymphocyte-rich tissue that makes up spleen, thymus, lymph nodes, red bone marrow, tonsils, and adenoids

Question 9

Lymphatic fluid function

Answer 9

A colorless liquid, rich with white blood cells (lymphocytes) that attack bacteria in the blood

Question 10

Lymph nodes function

Answer 10

Bean-shaped structures that filter out bacteria and viruses from the lymph fluid; a swollen lymph node is often a sign of an infection

Question 11

Primary function of the lymphatic system

Answer 11

Maintains the fluid balance between the blood and tissues by removing interstitial fluid

Question 12

Interstitial fluid def

Answer 12

Fluid that resides in the space between blood and tissues

Question 13

Additional functions of the lymphatic system

Answer 13

Fighting infection
Absorption of fats
Removing waste

Question 14

How does the lymphatic system fight infection

Answer 14

Lymph fluid carries lymphocytes to areas that the blood cannot reach to defend the body against infection

Lymph nodes filter foreign pathogens or microorganisms from lymph vessels

Question 15

How does the lymphatic system absorb fats

Answer 15

The lymphatic system facilitates absorption of fats Removing and fat-soluble nutrient in the gastrointestinal tract, which eventually becomes chyle

Question 16

Chyle def

Answer 16

A fat, glucose, and protein fluid leaked from the intestines that contains lymph and free fatty acids that are returned to the venous blood supply

Question 17

Lymph nodes (9)

Answer 17

Buccal (cheek area)

Submandibular (underneath mandible; drains the inner eyes, nose, cheeks, and upper lip)

Submental (collect lymph from central lower lip, floor of mouth and apex of tongue)

Parotid (in front of ears above the jaws; drain the scalp, upper face, eyelids, nose, and cheeks)

Occipital (at the base of skull; drain the back of the scalp and neck)

Pre and post-auricular (collect lymph from superficial areas of the face and temporal regions)

Mastoid (behind the ears; drain the scalp)

Deep cervical (deep within the neck and form a chain along the neck; all lymph from the head passes directly or indirectly through these nodes; drain the superficial nodes, tonsils, and tongue)

Superficial cervical (at the side of the neck; drain the scalp, occipital nodes and mastoid nodes)
