Exam 6 Material (Organ Systems, Homeostasis, and Temperature Regulation)

Question 1

How many organ systems are there?

Answer 1

11

Question 2

Which organ system is associated with the removal of excess water/the retention of water/along with the removal of various waste products (especially those made of nitrogen/made with nitrogen)?

Answer 2

Urinary system

Question 3

Which organ system deals with reproduction?

Answer 3

Reproductive system

Question 4

Why is maintaining homeostasis important?

Answer 4

Many animals work best at a certain temperature (b/c certain enzymes and processes work best at certain temperatures)

Question 5

Which type of animal is being described?:
- For some animals to maintain a temperature necessary to conduct the physiological responses the body must perform, they seek heat from their external environment (they will often exhibit behaviors to help increase the likelihood of being at the temperature they need to be at)

Answer 5

Ectotherms

Question 6

Which type of animal is being described?:
- animals that use homeostatic mechanisms to maintain their body temperature (will have certain structures like feathers, hair, or big ears/exhibit behaviors like panting or sweating)/do not seek heat from their external environment

Answer 6

Endotherms

Question 7

What is being described?:
- torpor (basically hibernation/overnight hibernation—-lowers their body temperature so that it’s closer to the outside environment/almost becomes like an ectotherm/allows them to expend less energy),
- hibernation (reducing their metabolic energy)

Answer 7

Coping mechanisms to help maintain homeostasis

Question 8

What is it called/what will form when you collect similar or associated tissues?

Answer 8

Organs

Question 9

What is it called/what will form when you have a collection of similar organs performing coordinated or similar functions?

Answer 9

Organ System

Question 10

Which organ system includes skin and hair?

Answer 10

Integumentary system

Question 11

Which organ system includes bone and cartilage?

Answer 11

skeletal system

Question 12

Which organ system includes skeletal, smooth, and cardiac muscles?

Answer 12

Muscular system

Question 13

Which organ system work in close coordination w/ the cardiovascular system and helps important immune cells circulate throughout the body as well as recover old dead cells immune cells/capture fluid that escapes the cardiovascular system?

Answer 13

immune and lymphatic systems

Question 14

Which organ system includes organs and tissues that circulate blood throughout the body?

Answer 14

Cardiovascular system

Question 15

Which organ system is associated w/ the exchange of oxygen and carbon dioxide with various organs and structures supporting this?

Answer 15

Respiratory system

Question 16

Which organ system allows for the obtainment of nutrients?

Answer 16

Digestive system

Question 17

Which organ system is made up of nervous tissue/contains endocrine glands and will then use the circulatory system to transport those compounds throughout the body?

Answer 17

Nervous system

Question 18

All organ systems work together to achieve what?

Answer 18

Homeostasis

Question 19

What is being described?:
- trying to maintain a relatively concentrated internal environment

Answer 19

Homeostasis

Question 20

What is being described (mechanism to help maintain homeostasis)?:
-you get stressed to help keep things the way they are supposed to be (ex: the fight-or-flight response)?

Answer 20

Stress-response system

Question 21

Which type of feedback loop is used to help maintain homeostasis?

Answer 21

Negative feedback loop
