Answer 2

Function

Question 3

What are the Dorsal Cavities?

Answer 3

Cranial and Vertebral Cavities

Question 4

What are the Ventral Cavities

Answer 4

Thoracic and Abdominopelvic Cavities

Question 5

Cranial Cavity?

Answer 5

houses brain

Question 6

vertebral cavity?

Answer 6

houses spinal cord

Question 7

Thoracic cavity?

Answer 7

upper part of torso, houses lungs and upper organs

Question 8

Abdominopelvic Cavity

Answer 8

the lower half of the torso; houses the stomach and lower organs. Deepens towards the buttocks

Question 9

What separates the thoracic and abdominopelvic cavity?

Answer 9

the diaphragm

Question 10

What are the two types of tissues that cover the organs?

Answer 10

Visceral and Parietal

Question 11

What type of tissue are visceral and parietal skins made of?

Answer 11

epithelial tissue

Question 12

What is visceral skin?

Answer 12

skin closest to the organ

Question 13

What is parietal skin?

Answer 13

the outer skin. Parietal means “wall.” This skin usually is furthest from the organ/covers the wall of the cavity. EX: Parietal pleura lines the pleural/thoracic cavity.

Question 14

Aside from protecting the organ, what else does the parietal skin do?

Answer 14

attaches the organs to the inner parts of the body to prevent movement.

Question 15

What is serous fluid?

Answer 15

a fluid between parietal and visceral skins. Contains electrolytes, and is isotonic and sterile.

Question 16

What is the purpose of serous fluid?

Answer 16

shock absorbent

Question 17

Inflammation in Organs is?

Answer 17

tearing of the ‘skins.’ Pain from inflammation comes from the skins as epithelial tissue has lots of nerve endings.

Question 18

What is the medical term for the Thoracic Cavity?

Answer 18

Pleural Cavity

Question 19

What is the medical term for the abdominopelvic cavity?

Answer 19

peritoneal cavity

Question 20

what is the mediastinum?

Answer 20

another ‘sac’ cavity in the middle of the Pleural cavity.

Question 21

What does the mediastinum contain?

Answer 21

the trachea, esophagus, the heart, and more

Question 22

what is the lower mediastinum called?

Answer 22

the pericardial cavity

Question 23

Types of lung skin?

Answer 23

Visceral and Parietal pleura, since it is in the pleural cavity

Question 24

Heart skin types?

Answer 24

visceral and parietal pericardium, since it is in the pericardial cavity in the mediastinum

Question 25

Peritoneal Cavity Organ skin types?

Answer 25

visceral and parietal peritoneum.

Question 26

Peritonial cavity 9 Quadrants? from left to right? (3x3)

Answer 26

right hypchondriac, epigastric region, left hypchondriac///// right lumbar, umbilical region, left lumbar,///// right iliac, hypogastric region, left iliac

Question 27

Homeostasis Definition

Answer 27

maintaining inner metabolism in the body (pH, temp, minerals, ions, etc)

Question 28

What type of regulation does most of the body use?

Answer 28

negative regulation?

Question 29

What organ is the regulator for homeostasis?

Answer 29

hypothalamus

Question 30

Exceptions that use positive regulation?

Answer 30

child delivery, blood clotting

Question 31

What happens when your temp rises? (in order)

Answer 31

vasodilation, sweating, increased heart rate, increased breath rate, and #3 and #4 lead to a higher blood pressure

Question 32

Why do fevers happen?

Answer 32

body thinks higher temps are normal

Question 33

which hormone interacts with the hypothalamus that some medicines act on to reduce fever?

Answer 33

prostaglandin

Question 34

What happens in a temp drop?

Answer 34

first you shiver, then the exact opposite of what happens in temp rise happens. (vasoconstriction, no sweat, decrease in HR, BR, and BP)

Question 35

serous membranes

Answer 35

the walls of the ventral body cavity and the other surfaces of the organs are covered with a thin, double layered membrane called the serous membrane
