Respiratory System Flashcards
What does the external respiration consist of?
nasal cavity, paranasal sinuses, pharynx, larynx
Also called external nares and contains the paranasal sinuses where air is warmed. This also contains the cilia that is responsible for filtering out foreign bodies.
Nose
The external nares is divided into three:
- Internal Nares
- External Nares
- Nasal Conchae
Opening to the exterior
Internal Nares
Opening to the pharynx
External nares
Folds the mucous membrane increases the air turbulence & ensures the air contacts to the mucous membrane.
Nasal Conchae
Space that is used by the respiratory and digestive
system. Originate in the nasal and oral cavities and extends inferiorly near the level of the bifurcation of the larynx and the esophagus.
Pharynx
Commonly called the throat and is a pathway for air and food.
Pharynx
What are the three sections of the pharynx
Nasopharynx, Oropharynx, Laryngopharynx
Has adenoids that helps the body immune defense
Nasopharynx
Back portion of the mouth contain palatine tonsils helps the body immune defense
Oropharynx
Bottom section of the pharynx where it divides the esophagus and larynx
Laryngopharynx
Called as the voice box somewhat cylindrical airway that ends in the trachea
Larynx
Flexible tube is called
windpipe
Trachea
enforce to the trachea to make sure the
trachea is open at all times
Cartilage
Has a conical shape. Its wide, concave base rests upon the muscular diaphragm.
Lungs
Both lungs are bordered by the ____ that is supported by the ribcage.
anterior thorax , lateral thorax and posterior thorax
The ____ lung is divided into 2 lobes and is smaller.
left
The ___ lung is divided into 3 lobes and is bigger.
right
Outer surface of each lung and the adjacent internal thoracic wall is lined by a serous membrane called ____.
pleura
The lateral surface of the
diaphragm is called
parietal pleura
Outer surface of each lung
visceral pleura
These are continuous at the hillus of each lung.
Visceral & Parietal Pleura
Air enters through a system pipes called ___.
Bronchi
Are the important work of gas exchange between the air and blood.
Alveoli
When breathing in, air comes down the ____ and through the ____ into the ____.
Trachea, Bronchi, Alveoli
At the bottom of the cavity is a
large, flat muscle that is called
the ____.
Diaphragm
What are the three basic structure of the skin?
- Epidermis
- Dermis
- Hypodermis
This covers, protects, and waterproofs the body.
Epidermis
What are the 5 layers of the skin?
Stratum corneum , Stratum lucidum, Stratum granulosum, Stratum germinativum, Stratum basale
Keratinized layer, prevent loss or entry of water
Stratum Corneum
Clear layer found on the thick skin
Stratum lucidum
Grainy layer, stops dividing, starts producing
Stratum granulosum
Innermost layer of the epidermis
Stratum germinativum
Attached to the basement membrane by hemidesmosomes
Stratum basale
are specialized junctional complexes, that contribute to the attachment of epithelial cells to the underlying basement membrane in stratified and other complex epithelia
hemidesmosomes
The ____ is composed of keratinized stratified squamous epithelium
Epidermis
What are the four major types of skin cells?
- Keratinocytes - Produces keratin
- Melanocytes - Produces melanin pigment),
- Langerhans cells - Immune responses,
rises from the red bone marrow - Merkel cells - Sensation of touch
Located between the epidermis and subcutaneous layer
Dermis
What are the two layers of the dermis?
- Outer papillary layer -contains
small capillaries, lymphatics,
sensory neurons - Deep reticular layer- Contains
collagens & elastics fibers,
Irregular connective tissue
Also called the Subcutaneous Layer
Hypodermis layer
Allows separate movement and made with areolar connective tissue and adipose tissues
Hypodermis
Connects the skin to
muscle, has white blood cells
areolar connective tissue
Stores energy, cushions bony
prominences
adipose tissues
Includes skin and accessory
structure including nail and hair.
Integumentary System
This covers our body and is the
largest organ of the body surface area and weight
Skin
Organs that forms the hair, located in the dermis
Hair Follicle
Smooth muscle, causes hairs to stand up
Arrector Pili
Lubricates the hair
Sebaceous Glands
Controls bacteria
Root Hair Plexus
A loose connective tissue wrapped in the hair follicle
Connective Tissue Sheath
lower part of the hair
Hair root
Upper part of the hair, consists of Medulla, Cortex, Cuticle
Hair Shaft
Base of the hair follicles
Hair Bulb
Made up of Keratinocytes
Hair Matrix
Regulates hair’s growth
Hair Papilla
Core, dead cells has soft keratin to be flexible
Medulla
Middle, dead cells has hard keratin to stiffness
Cortex
Out, overlapping dead keratinized cells from shiny surface
Cuticle
This part of the nail extend pass the skin
Free Edge
This part is visible in the nail area.
Nail Body
This part of the nail is the skin on both sides of the nail.
Nail Wall
This is the whitened half-moon of the nail.
Lunula
This part of the nail lies at the base of the nail
Eponychium
This part of the nail holds roots and matrix.
Mantle
This part of the nail generates cells to make nail
Matrix
This part of the nail is attached at the matrix.
Nail root
This part is the skin that the nail sits on.
Nail Bed
The nails slides on this part.
Nail Grooves
This is the skin around the nail.
Perionychium
This is underneath the free edge of the nail
Hyponychium
