Anatomy And Physiology Part 2

Front 1

What are the 3 muscle types?

Back 1

1. Skeletal

2. Cardiac

3. Smooth

Front 2

What is the function of Skeletal muscle?

Back 2

Skeletal muscle moves the bones under conscious nervous control.

Skeletal muscle is voluntary.

Front 3

What is the function of Cardiac muscle?

Back 3

Makes up the heart and requires no conscious nervous control.

Cardiac muscle is involuntary.

Front 4

What is the function of Smooth muscle?

Back 4

Moves along objects inside the body, such as food through the digestive tract or urine in the bladder. Smooth muscle is involuntary.

Front 5

What is Homeostasis?

Back 5

An equilibrium that must be kept to maintain life. Like air conditioning and heating keeping a room a certain temperature.

Front 6

What are the 3 types of chemical bonds?

Back 6

1. Covalent bonds

2. Ionic bonds

3. Hydrogen bonds

Front 7

How is a Covalent bond formed?

Back 7

A Covalent bonds is formed when atoms share electrons.

Front 8

How is a Ionic bond formed?

Back 8

An Ionic bond is formed when electrons are transferred from one atom to another

Front 9

How is a Hydrogen bond formed?

Back 9

A Hydrogen bond is formed between hydrogen atoms of already formed covalent bonds

Front 10

Which of the 3 Chemical Bonds is the weakest?

Back 10

The Hydrogen Bond

Front 11

How is a Polar Molecule formed?

Back 11

A polar molecule is formed when electrons spend more time at one end of the molecule than the other, resulting in the molecule end with more electrons having a slight positive charge and the end with fewer electrons a slight negative charge.

Front 12

What is a Polar Molecule?

Back 12

A molecule with slightly charged ends

Front 13

What is a cation?

Back 13

A positively charged ion

Front 14

What is an anion?

Back 14

A negatively charged ion

Front 15

What are the 3 types of chemical reactions?

Back 15

1. Synthesis

2. Decomposition

3. Exchange

Front 16

How does a Synthesis Reaction work?

Back 16

A new, complex chemical is created from multiple simple chemicals, ie A+B=AB

Front 17

How does a Decomposition reaction work?

Back 17

A single, complex chemical is broken down into multiple, simple chemicals; ie AB=(A) (B)

Front 18

How does an Exchange reaction work?

Back 18

Certain atoms are exchanged between molecules,

ie AC< >DB=AB><DC

Front 19

Contrast Solutes, Solution, Solvent

Back 19

Solutes: Chemicals added to water

Solution: Result of chemical plus water

Solvent: a substance into which other substances are dissolved

Front 20

What are the 4 special properties of water?

Back 20

1. Ideal transport medium

2. Has a high heat capacity

3. Has a high heat of vaporization

4. Good lubricator

Front 21

What are salts in their ionic form called?

Back 21

Electrolytes

Front 22

What is the simplest form of a carbohydrate?

Back 22

A simple sugar (monosaccharide)

Front 23

What is another name for neutral fats?

Back 23

Triglycerides

Front 24

Define Fatty Acid

Back 24

A chain of carbon atoms with 1 or hydrogen atoms attached by double or single bonds

Front 25

Define Saturated Fatty Acid

Back 25

A chain of carbon atoms where all bonds in the hydrocarbon chain are single and attached to the carbon

Front 26

Define Unsaturated Fatty Acids

Back 26

A chain of carbon atoms where some double bonds between the carbon and hydrogen atoms exist

Front 27

What do Lipoproteins do?

Back 27

Transport fats within the body

Front 28

What do Phosolipids do?

Back 28

Make up the lipid bilayer of cells

Front 29

What do Steroids do?

Back 29

Aid in the production of hormones

Front 30

What do Eicosanoids do?

Back 30

Mediate complex chemical processes
