Lymphatic And Digestic Flashcards

1
Q

are small structures that are oval to bean- shaped found along the length of lymphatics, that work as filters for harmful substances. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid- aka lymph glands

Q

WHERE DOES THE THORACIC DUCT EMPTY ALL OF ITS LYMPH INTO?

A

The left subclavian vein and the right lymphatic duct empties all of its lymph into the right subclavian vein, so the journey of the lymph is now completed.

Q

WHERE DO EFFERENT LYMPHATICS EXIT THE LYMPH NODE?

A

At the hilum, a slight depression on one side. Blood vessels and nerves also exit and enter at the hilum

21
Q

EFFERENT LYMPHATICS UNITE TO FORM HOW MANY LYMPHATIC TRUNKS?

A

6

22
Q

WHAT DO T-CELLS BIND TO?

A

Helper T cells bind with specific antigens presented by macrophages

23
Q

WHAT ARE PEYER’S PATCHES?

A

• Also known as aggregated lymphatic follicles.
• They’re found in the wall of the small intestine. They resemble tonsils. Their macrophages destroy bacteria. Bacteria are always present in large numbers in the intestine, and the macrophages prevent the bacteria from infecting and penetrating the walls of the intestine

24
Q

WHAT DOES THE BRONCHOMEDIASTINAL TRUNK DRAIN?

A

• Drains the thorax, lungs, heart, diaphragm, and the rest of the liver

25
Q

he passage of digested food from the digestive tract into the cardiovascular and lymphatic systems for distribution to the body’s cells

A

ABSORPTION

26
Q

he passage of digested food from the digestive tract into the cardiovascular and lymphatic systems for distribution to the body’s cells

A

PERISTALSIS

27
Q

he elimination from the body of those substances that are indigestible and cannot be absorbed

A

DEFECATION

28
Q

the breakdown of food by both mechanical and chemical mechanisms

A

DIGESTION

29
Q

WHAT IS THE GI TRACT?

A

• AKA- alimentary canal
• It’s a long continuous tube that runs through the ventral cavity of the body and extends from the mouth to the anus. The length of this tube is approximately 30 feet, or 9 meters. Its organs include the mouth or oral cavity, oropharynx, esophagus, stomach, and the small and large intestine. Muscular contraction in the tube break down food physically by churning it; enzymes from cells in the tube’s wall break down food chemically.

30
Q

WHAT ARE TUNICS?

A

• arrangement of tissue layers walls of the alimentary canal from the esophagus to the anal canal

31
Q

WHAT IS THE INNERMOST LAYER OF THE ALIMENTARY CANAL?

A

• tunica mucosa

32
Q

WHAT IS VITAMIN A NECESSARY FOR?

A

• Vision, bone growth, and maintenance or epithelial cells

33
Q

WHAT IS VITAMIN B FOR?

A

• Muscle and nerve function and functions as a coenzyme in energy metabolism

34
Q

WHAT IS THE UVULA?

A

• a conical projection hanging from the posterior border of the soft palate; functions in the swallowing process and prevents food from backing up into the nasal area

35
Q

WHAT IS UMAMI?

A
  • It detects MSG (monosodium glutamate), a distinct flavor popular in Asian foods
36
Q

HOW MANY INCISORS ARE THERE?

A

• 8
• They are the front teeth

37
Q

WHAT IS THE HARDEST SUBSTANCE IN THE BODY?

A

• Tooth enamel

38
Q

WHAT IS ANOTHER NAME FOR SWALLOWING?

A

• deglutition

39
Q

collapsible, muscular tube located behind the trachea that transports food to the stomach

A

Esophagus

40
Q

• narrow inferior region of the stomach
• Also called the antrum

A

PYLORUS

41
Q

secrete hydrochloric acid in the stomach

A

PARIETAL CELLS

42
Q

A highly specialized structure developed for synthesis, storage, and secretion of digestive enzymes

A

ACINI CELLS

43
Q

eat bacteria and old white and red blood cells; found in the liver

A

KUPFFER CELLS

44
Q

It’s function is to store and concentrate bile produced by the liver lobules until it is needed in the small intestine

A
  1. WHAT IS THE GALLBLADDER FOR?
45
Q

WHAT IS THE FIRST PART OF THE SMALL INTESTINE?

A

• Duodenum

46
Q

WHAT IS CHYME?

A

• Chyme is the term used to describe the digested, viscous, semifluid contents of the intestine

47
Q

WHAT IS THE FIRST PART OF THE LARGE INTESTINE?

A
  • cecum
48
Q

WHAT DOES THE LIVER DO?

A

• Processes the blood and break down, balance, and creates the nutrients and also metabolizes drugs into forms that are easier for the rest of the body that are non-toxic

49
Q

WHAT DO THE CHIEF CELLS SECRETE?

A
  • principal gastric enzyme pepsinogen
