29
Q

The nervous system is divided into a _________ and ________.

A

(CNS) Central nervous system AND (PNS) Peripheral nervous system

30
Q

What is the Central Nervous System?

A

Processing ‘hub’ that sends and receives info to and from the entire body (brain and spinal cord)

31
Q

What is the Peripheral nervous system?

A

Nerves that attach the CNS to the body’s organs and extremities

32
Q

What is the sub level of the PNS?

A

(ANS) Autonomic nervous system—operates involuntary motor nerves processes

33
Q

What is the longer nerve of a nerve cell called?

A

Axon

34
Q

Electrical impulses travel along the axon and jump across ______ to other nerve cells.

A

syanapses

35
Q

What is peristalsis?

A

When the esophagus moves food by waves of muscle contractions

36
Q

What two systems is the pancreas part of?

A

digestive and endocrine

37
Q

What does the pancreas do in the digestive system?

A

Makes powerful juices called enzymes that further breaks down food as it enters the small intestines

38
Q

What is the stomach?

A

thick muscles which contract to mash up food, secretes strong protein juices that attack food and absorb nutrients

39
Q

What does the gall bladder do?

A

Stores fluid called Bile which flows into the small intestine to break down fatty foods

40
Q

What does the small intestine do?

A

Where most of the absorption of nutrients occurs.

41
Q

What does the liver do?

A

Receives blood from intestines full of nutrients and other products from digestion.

42
Q

What does the large intestine do?

A

Absorbs useful substances leftover and puts back into blood. Remains are formed into semi-solid waste product.

43
Q

What does the rectum and anus do?

A

Rectum stores feces and squeezed through anus out of the body

44
Q

What are the lines of defense of the immune system?

A

skin; linings of respiratory and digestive passageways; blood-clotting; white cells; thymus gland in the chest and small lymph nodes/glands

45
Q

What are lymph nodes?

A

Act as filters throughout the body and fill up with extra white blood cells and “dead” pathogens.

46
Q

What is the Thymus Gland?

A

Produces and “educates” T-cells which attack foreign substances. Most active during childhood and then break up into islands of fatty tissue.

47
Q

What is the spleen?

A

Behind the stomach, makes and stores various kinds of white and red blood cells. A blood filter.

48
Q

What are tonsils and adenoids?

A

Tonsils are patches of lymph tissue on the upper rear of the throat. Adenoids are similar in rear of nasal cavity of nose.

49
Q

Where can white blood cells be found in the immune system?

A

Lymph Nodes, thymus gland, spleen, tonsils and adenoids

50
Q

What is the Endocrine system?

A

glands that communicate and maintain homeostasis using specific hormone secretions into the bloodstream

51
Q

What are some regulated functions of the endocrine system?

A

mood, sleep, growth and development and metabolism

52
Q

What are the glands of the endocrine system?

A

Pituitary gland, pineal gland, thyroid gland, thymus, adrenal gland, pancreas, ovary/testis

53
Q

What gland is the “master” endocrine gland?

A

Pituitary gland—junction of the nervous system and endocrine system come together at the hypothalamus—also responsible for ANS

54
Q

What functions does pituitary gland control?

A

skeletal growth, development of sex glands, blood pressure and pain relief and regulation of other glands

55
Q

What does the thyroid gland do?

A

Controls how quickly body uses energy and regulates metabolism

56
Q
