Cardiovascular & respiratory system Lab

Aorta

largest artery in the body

Apex

The narrow tip of the heart

Auricle

The largest and most visible part of the atria

Base

the widest part of the heart which is located upward and learning towards the right shoulder.

Coronary vessels

supply of oxygen and nutrient and the prompt removal of waste

Interventricular groove

is the stout wall separating the lower chamber of the heart form one another

pulmonary artery

Which supplies the lungs with blood to deoxygenated

pulmonary vein

That deliver blood into the left atrium

Vena cava

brings deoxygenated blood to the heart

Ventricle

is one of two large chambers that collect and expel blood received from the an atrum.

Aortic valve

Located between the left ventricle and the aorta

atrium

the carniodorsal chambers of the heart

Chordae tendineae

The flaps of the valve are prevented from bending back into the atrium

Interatrial septum

This separated the artrium

Interventricular septum

This separated the ventricle from each other

Mitral valve

This valve controls the opening between the left atrium and left ventricle

Myocardium

middle and thickest layer of the heart

pectinate muscle

The chordea tendineae connect the free edges of the valvular flaps which attach inside the ventricle on the inter ventricular septum that separates the right and left vetricle.

Trabeculae

are rounded or irregular muscular columns which project from the inner surface of the right and left ventricle of the heart

papillary muscle

are muscle located in the ventricle of the heart.

moderator band

is a muscular band of the heart found in the right ventricle of the heart is welled marked in sheep.

Nasal meatus

is a nasal passage of the nasal cavity, of which there are 3, superior,middle and inferior.

Turbinates

are thin, scroll-like bones with nasal epithelium that occupy most of the lumen of the nasal passages

Nasal meatus

divide each nasal passage into three main passageway

frontal sinus

SINUS LOCATED IN THE FOREHEAD OF THE SKULL

Maxillary sinus

forms a large cavity above the roots of the maxillary molars

Hard palates

Hard, bony, anterior portion of roof of mouth formed by parts of palatine and maxillary bones

glottis

opening into the larynx

Epiglottis

cover the glottis when the animals swallows

Aryenoid cartilage

vocal cords

Trachea

Anterior to Bronchi then splits in to bronchi; for conduction of air; hyaline cartilege (15-20 incomplete rings); has ciliated epithelium

Esophagus

Larynx is ventral to what?

cilated Psendosttratified Epithelium

This epithelium line the trachea to help move dirt and dust way from the lungs.

Cranial lobe

The red arrow is pointing what point of the lung?

Middle lobe

The green circle of the right lung

Caudal lobe

The surgical tool is point to the right lung

Crainal lobe

The yellow arrow is pointing to what part of the lung?

Caudal lobe

The red arrow is pointing to the left lung of what lobe.

Accessory lobe

The highlighted area is what area.

Where do adult heartworms live?

In pulmonary arteries, right atrium, and right ventricle

What r the consequences of chronic heart worm disease on the heart?

Hypertrophy,failure, myorrhea

What r the consequences of chronic heart worm disease on the lungs?

Cough, inflammation, blockage

What vessel and what chamber have been ruptured by a massive heart worm infestation?

Pulmonary arteries, right ventricles, vana cava

Identify the vessels and chambers where the heart worm live?

Pulmonary arteries, right atrium.

What are intercalated disc?

Cells of cardiac muscles fit together to form
these structural medications that allow the cardiac muscle to act as a unit.

What is the difference between the artery veso, capillary.

1. outer layer is tunica adventita
2. middle layer is tunica media
3. inner layer is tunica intima

Which valve is the most common in chronic Valvlar disease?

Mitral valve

Canine Dilated Cardiomyopathy

What would be consequence of thin, atrophied,weak ventricular walls?

increased diameter of cardiac muscle.

What does Hypertrophic means?

Thick inwards
abnormally increased muscle mass due to a hypertrophied non dilated left ventricle making it harder to pump blood

What is this sick cat's heart often most visibly enlarged? Feline Hypertrophic cardiomyopathy:

Boxer
Great Danes
Irish wolfhounds

What types of dogs is canine Dilated cardiomyopathy disease most common?

Frontal Sinus

one of a pair of cavities in the frontal bone

Nasal septum

Divides the nasal cavity into left and right portions

sphenoidal sinus

bisected right below the sella turcica and posterior to the nasal cavity

ethmoidal sinus

a sinus of the meatuses of the nasal cavity (behind the bridge of the nose)

Nasopharynx

Communicates with the nasal cavity and provides a passageway for air during breathing

oropharynx

Central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis

sinusitis

An inflammation of the tissues that line the sinuses
