Plasma makes up what percentage of blood?
55% (Fifty - Five)
What is the biological name of blood cells that transport hemoglobin?
Erythrocytes.
Neutrophils, Eosinophils, Basophils, Monocytes, and Lymphocytes are all what classification of blood cell?
Leukocytes.
What is the biological name for platelets?
Thrombocytes.
What is the biological name for blood cells that participate in the immunity or defense mechanisms of the body?
Leukocytes.
What is the biological term name of cells that transport oxygen and carbon dioxide?
Erythrocytes
What blood cells are involved in hemostasis?
Platelets.
The majority of the heart is this layer.
The Myocardium.
Myo = Muscle.
Cardim = Heart.
The inferior and pumping chambers of the heart are called this.
The Ventricles.
What structure of the heart ensures that blood flows in one direction?
Valves.
The superior and receiving chambers of the heart are called this.
The Atriums.
Mechanisms that stop blood from escaping from inquired structures is called this.
Hemostasis.
Hemo = Blood
Stasis = State of balance.
When a lumen enlarges or widens, what do we say is happening to the blood artery or vein?
Vasodilation.
The sound of a heart beat is what action taking place?
The Closing of Valves in the Heart.
What valve ensures that blood does not return to left ventricle?
The Aortic Valve.
Which valve ensures that blood does not return to the right ventricle?
The Pulmonary Valve.
Pulmonary = Lungs.
The space or opening in the center of an artery or vein is called this.
The Lumen.
Vasoconstriction causes the lumen of the vein or artery to do this.
Narrow.
An increase of local blood flow is called this.
Hyperemia
Hyper = Over Active
Emia = Blood or Blood Substance.
A decrease in local blood flow is called this.
Ischemia.
Isch - Hold back.
Emia = Blood or Blood Substance.
What artery is the only one to transport oxygen depleted blood?
The Pulmonary Artery.
Artery = Blood is moving away from the heart.
Pulmonary = Lungs.
Blood is moving from the heart to the lungs so it does not have oxygen yet.
The amount of force exerted on the blood vessel walls as the heart contracts and relaxes is commonly called this.
This is where blood and tissue cells make an exchange, commonly of oxygen and carbon dioxide.
The Capillaries.
What is the only vein that transports oxygen-rich blood?
The Pulmonary Vein.
Pulmonary = Lung.
Vein = Blood flowing toward the heart.
Blood is leaving the lungs and heading back to the heart to be circulated throughout the body.
The rate in which blood returns to the heart from an organ is called this.
Venous Return.
This pathway is two capillary beds connected to a system of veins.
The Portal System.
Besides the heart, where else would you find valves in the circulatory system?
Veins.
What number should you remember when it comes to the heart?
Four (4)
4 Chambers. Atrium. Ventricle. Atrium. Ventricle.
4 Valves. Tricuspid. Pulmonary. Mitral/Bicuspid. Aortic.
4 Layers. Endocardium. Myocardium. Epicardium. Pericardium.
4 Circulations. Coronary. Pulmonary. Lymphatic. Systemic.
4 Sections to Remember. (Listed Above. 4 X 4)
The largest artery, namely in terms of diameter, is called this.
The Aorta.
This pathway replenishes oxygen while eliminating carbon dioxide.
The Pulmonary Circuit.
What are erythrocytes, leukocytes, and thrombocytes suspended in?
Plasma.
What produces red blood cells?
What is the scale of what blood looks like in terms of color?
Bright Scarlet to a Dull Maroon.
The Cardiovascular System.
What determines the color of blood?
Oxygen Concentration.
Hematopoiesis is the process of what?
Blood Cell Production.
