Terminology: Cardiovascular and Respiratory Systems Flashcards
What does RBC stand for?
RBC stands for Red Blood Cells
What does WBC stand for?
WBC stands for White Blood Cells
What are Thrombocytes?
Thrombocytes which are known as platelets, play a role in blood clotting.
It helps with injuries by helping to stop the bleeding and promote healing.
What is Hemoglobin?
Hemoglobin is a protein in the red blood cells that carries oxygen to the cells and tissues of the body.
What is Erythropoietin?
Erythropoietin is a hormone that stimulates the production of red blood cells
What is Phagocytes?
Phagocytes are white blood cells that defend against microorganisms by engulfing and destroying foreign particles.
What is Thrombocytopenia?
Thrombocytopenia is a condition in animals where there are fewer platelets in the blood.
What is Mediastinum? And what does it contain?
Mediastinum is the central compartment of the thoracic cavity surrounded by loose connective tissue.
It contains the heart, esophagus, and trachea.
What is Pericardium?
Pericardium is a fluid-filled sac that surrounds and protects the heart.
What is Myocardium?
Myocardium is the muscular layer of the heart wall responsible for contracting and pumping blood throughout the circulatory system.
What is Endocardium?
Endocardium is the inner most lining of the heart and
What is Septum? And what is the role?
The heart Septum is a wall separating the lower right and left ventricles.
It helps the heart pump blood efficiently by preventing it from flowing back into the heart chambers.
What is Auscultation?
Is the act of listening to the internal sounds of an animal to examine its systems, usually with a stethoscope.
What is Palpation?
A method of feeling with the hands and fingers during physical examination.
What is Regurgitation?
Regurgitation in the cardiovascular system is when a valve in the heart doesn’t close properly, causing blood to flow backward into the previous chamber of the heart.
What is Dilation?
Is a condition in which the left ventricle, the heart’s main pumping chamber, is enlarged.
What is Systole?
Systole is the phase of the cardiac cycle when the heart muscle contracts, forcefully pushing blood into the arteries.
What is Diastole?
The period of the cardiac cycle when the heart’s ventricles relax and fill with blood.
“Relaxation Phase”
What is Asystole?
When your heart’s electrical system fails entirely, which causes your heart to stop pumping. It is also known as “flat-line” or “flat-lining”.
What is Sinus rhythm?
The normal heart rate rhythm in animals.
What is Arrhythmia?
An abnormal heart rhythm in animals.
What is Sinus Arrhythmia?
Sinus arrhythmia is a normal finding in dogs; it is abnormal in cats in the hospital setting, although it appears to be more common in cats in their home environment. Respiratory sinus arrhythmia is characterized by an increase in heart rate with inspiration and a decrease with expiration.
What is Bradycardia?
A condition in which an animal’s heart rate is slower than normal.
What is Tachycardia?
A rapid heart rate that exceeds a certain number of beats per minute (bpm) for a given species
What is Respiration?
The process by which an animal exchanges oxygen and carbon dioxide with its environment.
- Breathe in O2 and breathe out CO2
