The thoracic duct begins at the sac called ______________________ (two words)

The nonspecific defense system is called ___________________________ immunity.

The specific defense system is called ______________________________ immunity.

Skin and mucous membranes are part of the _______________________ line of defense.

HCl in the stomach is part of the _______________________ line of defense

Inflammation and fever are part of the _____________________line of defense

Answer 1

• Axillary lymph nodes are located in the armpit. (Armpit is also known as Axilla, contains more than 20 lymphnodes).
• Cervical lymph nodes are located in the neck. ( They are further divided into anterior and posterior cervical lymphnodes).
• Inguinal lymph nodes are located in the groin. (These lymphnodes are very small).
• All lymph vessels are eventually going to empty into the right lymphatic duct and the thoracic duct.( These two are the main two lymphatic ducts present in the body to help in lymphatic drainage).
• Thoracic duct begins at the sac called cisterna chyli. ( It is a dilated sac of main lymphatic trunk).
• The non specific defense system is called Innate immunity. ( It is also called as natural immunity which is the first line of defense and contains physical barrier)
• The specific defense system is called Acquired immunity. ( It is also known as adaptive immunity which is obtained from an attack of a pathogen into the human body, develops antibodies against them).
• Skin and mucous membranes are the part of the first line of defense.(There are 3 lines of defense where the first line includes physical and chemical barriers).
• HCl in the stomach is part of the first line of defense. (Human body defense mechanism contains 3 lines of defense,where the first line contains physical and chemical barriers).
• Inflammation and fever are part of the second line of defense. (The Second line of defense contains macrophages, interferons, neutrophils etc).
