The contraction of smooth muscle in blood vessels (vasoconstriction) can reduce the flow of blood through the vessel.

Question 4

Histology would be best defined as a study of ________.

Answer 4

tissues

Question 5

Which of the following best demonstrates the principle of complementarity of structure and function?

Answer 5

Bones can support and protect body organs because they contain hard mineral deposits.

Question 6

Choose the correct order for the missing levels of structural organization: Chemical,______,_____,____,____, organism

Answer 6

cellular, tissue, organ, organ system

Question 7

Identify the organ system responsible secreting hormones that regulate growth, development, and metabolism.

Answer 7

Endocrine system

Answer 15

Endocrine

Question 16

Trachea, bronchi, alveoli.

Answer 16

Respiratory

Question 17

Which organ systems function as control systems, communicating with other cells and organs to regulate their activities?

Answer 17

nervous and endocrine systems

Question 18

Lungs carry out an excretory function.

Answer 18

True

Question 19

In what way does physiology depend on anatomy?

Answer 19

The operation or function of a structure is promoted or prevented by its anatomy. For example, oxygen and carbon dioxide are exchanged across the very thin membranes of the lungs but not across the very not across the much thicker skin.

Question 20

Would you be studying anatomy or physiology if you investigated how muscles shorten? If you explored the location of the lungs in the body?

Answer 20

Muscle shorting is a topic of physiology. The body location of the lungs is an anatomy topic.

Question 21

gastritis

Answer 21

Inflammation in the stomach

Question 22

Leukocyte

Answer 22

White cell

Question 23

What separates living beings from non-living objects?

Answer 23

living organisms can maintain boundaries, move, respond to environmental changes, digest nutrients, and grow. While nonliving objects may exhibit some these properties, they do not exhibit all of them.

Question 24

Nephropathy

Answer 24

Kidney disease

Question 25

What name is given to all chemical reactions that occur within body cells?

Answer 25

Metabolism is the term that encompasses all the chemical reactions that occur in body cells.

Question 26

what level of structural organization is typical of a cytologist's field of study?

Answer 26

Cytologists study the cellular level of organization

Question 27

what is the correct structural order (simplest to most complex) for the following terms: tissue, organism, organ, cell?

Answer 27

The order in the structural hierarchy is cell, tissue, organ, and organism

Question 28

Which of the following are survival needs of the body?

Answer 28

nutrients, water, atmospheric pressure, and oxygen

Question 29

What process allows is to adjust to either extreme heat or extreme cold?

Answer 29

Negative feedback mechanisms allow us to adjust to conditions outside the normal temperature range by causing heat to be lost from the body (in hot conditions) and retained or generated by the body (in cold conditions)

Question 30

When we begin to get dehydrated, we usually get thirsty, which causes us to drink fluids. Is thirst part of a negative or a positive feedback control system?

Answer 30

Thirst is part of a negative feedback control system because it prods us to drink, which ends the thirst stimulus and returns body fluid volume to the normal range.

Question 31

why would a control system be called a positive feedback mechanism? what event ends it?

Answer 31

This is a positive feedback mechanism because it enhances the change (formation of a platelet plug) set into motion by the stimulus (damage to the blood vessel). The response ends when the platelet plug has plugged the hole in the blood vessel

Question 32

Homeostasis is the condition in which the body maintains ________.

Answer 32

a relatively stable internal environment, within limits

Question 33

In a homeostatic control mechanism, which component monitors the environment?

Answer 33

receptor

Question 34

the following example of feedback mechanisms. Used for changes in blood glucose levels:

Answer 34

Negative feedback

Question 35

the following example of feedback mechanisms. Used for changes in blood pressure:

Answer 35

Negative feedback

Question 36

the following example of feedback mechanisms. Used when activating the digestive system before an upcoming meal:

Answer 36

Positive Feedback

Question 37

the following example of feedback mechanisms. Used for childbirth:

Answer 37

Positive feedback

Question 38

Which of the following is the correct description of the human body while in the anatomical position?
