Chyle, everywhere else lymph is a clear, yellow fluid

The hand is located at the ________ end of the forearm

Distal

The lymphatic system would not

Empty into the arterial system

False

Lymph nodes function as ________ to remove bacteria and other foreign bodies including malignant cells

Filters

Each of the following arteries are pair except the

Hepatic artery

Thymus gland is located

In the upper anterior part of the Thoracic cavity

The Thoracic duct returns lymph into the cardiovascular system by way of the

Left subclavian vein

Thoracic duct returns lymph into the cardiovascular system by way of the

Left subclavian vein

2nd pair of tonsils are called the

Lingual tonsils

Lymphatic system is composed of a clear fluid called

Lymph

_______ is a clear, yellow, watery fluid found in the lymph vessels

Lymph

Oval shaped structures located along the entire length of lymph vessels

Lymph nodes

The ________ __________ is very important in maintaining fluid balance and helps in immunity within the body

Lymph system

Lymph nodes and vessels called ______ ________ transport the lymph

Lymph vessels

Lymph nodes are widely distributed throughout the body along the lymphatic pathways where they filter the __________ before it is returned to the ________

Lymph, blood stream

Lymph does not have red blood cells or platelets but does contain

Lymphocytes

Tonsils

Masses of lymphatic tissue embedded in the mucous membrane within the oral cavity and nasopharynx

The presence of these lipids (lacteals) gives the lymph a

Milky ( creamy) like appearance

thoracic duct (left lymphatic duct)

Much longer than the right; 15-18 inches long

The spleen contracts forcing blood into circulation

Need blood during an emergency

Most common tonsils are the

Palatine ( which we call our tonsils)

Most numerous in the section of the intestines called the ileum ( which happens to be the longest portion)

Peyer's patches

The tonsils located near the upper part of the throat are called the

Pharyngeal tonsil

The singular tonsil located in the upper part of the throat ( nasopharynx) is called

Pharyngeal tonsil or adenoid

Adenoids are another name for the

Pharyngeal tonsils

Lymph is similar to ______ but without many large proteins

Plasma

Cisterna =

Reservoir

Smaller of the two vessels

Right lymphatic duct

The Thoracic duct receives lymph from almost all areas of the body except the

Right side head, neck, chest

The heart chamber in which pulmonary circulation originated in is

Right ventricle

Lacteals (lact= milky)

Small ducts that conveys lymph and dietary lipids from the villi of the small intestines to the cisterna chyli

Peyer's patches are aggregations ( groups ) of lymph nodes located along the entire length of the

Small intestines

receives lymph from the left side of the head, neck, chest, abdomen, left arm, and lower extremities and entire body below the ribs

The Thoracic duct

The ________ cavity contains the heart, lungs, trachea, esophagus, large blood vessels, and nerves

Thoracic

This gland is a bi-lobed lymphatic organ

Thymus gland

Located behind the sternum and between the lungs

Thymus gland ( produces lymphocytes)

Produce lymphocytes and filter bacteria

Tonsils

Lymph in the small intestines is called chyle

True

Lymph vessels have thinner walls and more valves than veins

True

Lymph vessels originate as lymphatic capillaries

True

The largest mass of lymphatic tissue is the spleen

True

The veins that collect blood from the brain and convey it towards the heart are called sinuses

True

The white blood cells that are produced in the lymph organs are called lymphocytes

True

There are four orifices through which blood enters the left atrium of the heart, but only one for blood to exit from it

True

Villi increase the absorption area of the small intestines

True

With regard to the layers of the large blood vessels, going from the superficial to deep, which of the following groups is correct

Tunica adventitia - media - intima

If a cut is made into the aorta, which of the following would be cut secondly

Tunica media

There are _____ pairs of tonsils and ____ single tonsil

Two & one

Lymph vessels resemble the structure of

Veins in that they have the same 3 layers (tunica intima, tunica media and tunica adventitia), but they are thinner walls and more valves

Finger like projections found along the mucosal walls of the small intestines

Villi

The word caudal is a directional term that indicates

away from the head

a term that represents one of the basic tissues of the body is

epithelial

The spleen is located in the

left hypochondriac region

Spleen is located

left hypochondriac region between the stomach and diaphragm. It is lateral to the liver.

The tonsils located near the base of the tongue are called the

lingual tonsils

All of the following are lymph organs except the

liver

lymph vessels begin as

lymph capillaries, which are the smallest of the lymph vessels
