Anatomy 1: Organization of The Body (Systems) Flashcards
A. Intergumentary System
ACCESSORY STRUCTURES
The Intergumentary System is the study of skin and it’s accessory structures.
Examples of accessory structures are: hair, fingernails, & toenails.
- The definition of a system
GROUP
A system is a group of two or more organs combining together to perform a common function
B. Skeletal System
BONES
The Skeletal System is the study of the bones in the body
C. Digestive System
FOOD & LIQUID BREAKDOWN
The Digestive System is the study of organs used in breaking down food and liquids which we ingest.
D. Respiratory System
BREATHING
The Respiratory System is the organs involved in breathing or exchanging oxygen to waste gases
E. Endocrine System
ENDOCRINE GLANDS
The Endocrine Systems is the study of the endocrine glands
F. Excretory Systems
WASTE PRODUCTS
The Excretory System is the study of the organs involved in producing and ridding the body of waste products
G. Nervous System
NERVES
The Nervous System is the study of the organs involved in producing and transmitting nerve impulses throughout the body.
I. Central Nervous System: consists of the brain and spinal column (CNS)
II. Peripheral Nervous System: sends impulses on the based to the spinal nerves or to the brain (PNS)
H. Reproductive
SEX ORGANS
The reproductive system is production of offspring.
I. Muscular
MUSCLES
The muscular system are muscles of the body, organs, that are involved in the movement of and within the body.
J. Circulatory
CIRCULATION
The circulatory system is the production and shipment of blood throughout the body.
- The definition of Organ
TISSUES
The organ is two or more tissues combined together to perform a common functions.
Examples of organs are liver, stomach, and, spleen.
- The definition of tissue.
The tissue is two or more cells combined together ergo perform a common function.
A. Epithelial- lining tissues, and outer layers of the body and the innermost layer of any organ (Blood Vessels, G.I. Tract)
B. Connective- connects or joins parts of the body to each other (ligaments, tendons, cartilage, bone, fat)
C. Muscle- movement of and within the body (cardiac, skeletal, & visceral)
I. Cardiac: only only found in the heart. Involuntary muscle
II. Skeletal: attached indirectly to our muscle by tendons
III. Visceral: makes up the organs
D. Nerve- transmits nerve impulses
5 Types of Connective Tissues:
- Ligaments- connects bone to bone
- Tendons- connects muscle to bone
- Cartilage- connective tissue (not much info given)
- Bone- the hardest connective tissue we have in our body
- Fat- is another example of connective tissue
- Cells
Tissue builders
The cells are structural and functional units of life.
