0

When does a disease occur?

When the body can not maintain homeostasis.

1

What's the major function of the skeletal system?

It is composed of 206 bones and provides the essential functions of support, movement, and protection for the structures of the body

2

What is the major functions of the muscular system?

Is composed of fibers that contract, causing movement. The body contains three types of muscles: skeletal (striated), smooth and cardiac.

3

What is the major function of the lymphatic system?

Is a passive circulatory system that transports lymph, a thin plasma-like fluid formed from interstitial or extracellular fluid that bathes the tissues of the body.

4

What is the major function of the immune system?

Is integrally related to the lymphatic system and is the body system that mounts a defense against foreign substances and disease-causing agents.

5

What is the major function of the nervous system

Is a complex array of structures that help control body activities, both voluntary and involuntary

6

What is the major function of the gastrointestinal system

Is composed of structures and organs involved in the consumption, digestion, and elimination of food

7

What is the major function of the urinary system

Removes waste products from the blood and buy a complex filtration process, producing urine

8

What is the major function of the reproductive system

Includes the structures, both female and male, that are responsible for sexual reproduction

9

What is the major function of the endocrine system

Consist of glands located throughout the body that secrete proteins called hormones to regulate body functions

10

What is the major function of the integumentary system

Because the skin, nails, hair and sweat and oil glands

11

What is the organizational levels of the body

Atoms
Molecules
Macromolecules
Organelle
Cell
Tissue
Organ
Organ system
Organism

12

What are the two aspects in which a hip can be dislocated?

Anterior and posterior

13

In an anterior hip dislocation how is it positioned

Foot is externally rotated and the head of the femur is palpable in the inguinal area

14

Posterior hip location positioning

Most common type

The knee and foot are flexed internally.

15

Describe a fracture of the distal radius

Produces a characteristic silver fork deformity.

16

What are the three common forms of radiation

Alpha
Beta
Gamma (most penetrating type, similar to x-ray)

17

What are the 4 types of chemical reactions

Synthesis reaction
Decomposition reaction
Exchange reaction
Reversible reaction

18

Synthesis reaction characteristics

Always involves formation of new chemical bonds

Requires energy

Is important for growth and repair of tissue

A+B = AB

19

Decomposition characteristics

Example would be decomposition reactions in the digestive tract break molecules into smaller fragments before absorption

AB = A + B

20

Exchange reaction characteristics

AB + CD = AD + CB

21

Reversible reaction characteristic

A + B = AB, then AB = A + B

22

What is the importance of enzymes

They make chemical reactions possible.

23

What are the two classes of nucleic acids

Deoxyribonucleic acid (DNA)

Ribonucleic acid (RNA)

24

What are the three types of RNA?

Messenger RNA (mRNA)
Transfer RNA (tRNA)
Ribosomal RNA (rRNA)
