Cards

Term
Larynx
Definition

(the voice box)

 primary function is to keep food and drink out of the airway

also plays a role in sound production
 

Term
"Adams Apple" 
Definition

an anterior peak of the thyroid cartilage called the laryngeal prominence. Testosterone stimulates its growth.

Term
Trachea
Definition

Windpipe, allows passage of air into lungs

 

Identified by the C shaped rings lining it

Term
Lungs
Definition

Cat lungs - Several lobes, right side has 4 (including mediastinal) left only with 3

Anterior, Middle, Posterior lobes

 principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere.

Term
Diaphragm
Definition

Skeletal Muscle

facilitates breathing with its cycle of contraction and relaxation

Kinda looks like a thin mushroom in the cat between thoracic and abdominal regions

Term
Why do we breathe?
Definition

Most of our metabolism directly or indirectly requires ATP. Most ATP synthesis requires oxygen and generates CO2 – thus driving the need to breathe in order to supply the former and eliminate the latter. 

Term
Describe what the lung model from class represents
Definition
Breathing. When the diaphragm pulls down (contracts) the lungs fill up with air. When it relaxes and moves back up it pushes air out of the lungs
Term
Tidal Volume
Definition
(Spirometer Exercise)

Amount of air inhaled/exhaled with each breath under resting conditions

Approx 500ml 
Term
Inspiratory Reserve Volume
Definition
Amount of air that can be forcefully inhaled after a normal tidal volume inhalation

Approx 3100ml 
Term
Expiratory Reserve Volume
Definition
Amount of air that can forcefully exhaled after a normal tidal volume exhalation

Approx 1200ml 
Term
Vital Capacity
Definition

Maximum amount of air that can be exhaled after a maximal inspiration.

 

Approx 4800ml

VC = TV + IRV + ERV 

Term
What medical condtions can the spirometer be used to diagnose?
Definition
Emphysema, COPD
Term
Lymphatic System
Definition

A system of vessels, tissue, nodes, and organs which function in both carrying lymph and performing tasks related to immunity


EX: tonsils, thymus, and spleen

Term
Lymph
Definition

a clear-to-white fluid made of:

White blood cells, especially lymphocytes, the cells that attack bacteria in the blood
Fluid from the intestines called chyle, which contains proteins and fats
Term
How do cells recieve nutrients?
Definition
All of the cells in your body are bathed in lymph, and they receive their nutrients and oxygen from the lymph.
Term
Spleen
Definition
removes old RBCs (filtration) and holds a reserve of blood in case of hemorrhagic shock (most commonly caused by trauma). 
Term
Lymph Nodes
Definition

tiny little bean shaped thingies. located in clusters in various parts of the body, such as the neck, armpit, groin, and inside the center of the chest and abdomen.

  Lymph nodes produce immune cells that help the body fight infection

Term
Thymus
Definition

functions in the development of lymphocytes. Begins to atrophy in early teens. In older people it is tiny or non existant.

Term
Glycosuria
Definition
The presence of glucose in the urine

indicative of Diabetes 
Term
Average pH of urine
Definition
6.0 (acidic)
Term
Albuminuria
Definition
the presence of albumin in the urine

indicative of pregnancy, excessive exertion, or overabundant protein intake 
Term
Ketonuria
Definition
presence of ketone bodies in the urine

indicative of starvation or malnutrition

if coupled with glycosuria it indicates diabetes 
Term
Hematuria
Definition
presence of red blood cells in the urine


indicative of
irritation of the urinary tract or physical trauma to urinary organs (Kidney stones can cause these irritations)

(when normal menstrual cycle is ruled out) 
Term
Hemoglobin in the urine
Definition

resulting in the fragmentation (hemolysis) of red blood cells 


indicative of hemolytic anemias, transfusion reactions, burns, poisonus snake bites, or renal disease 
Term
Nitrites in the urine indicate
Definition
bacterial infection
Term
Bilirubinuria
Definition
presence of bilirubin in the urine

indicates liver pathology (hepatits, cirrhosis of the liver, or bile duct blockage) 
Term
Pyuria
Definition

white blood cells in the urine


indicates inflammation of the urinary tract
