Q1: Lesson 1 | Circulatory System Flashcards
It consists of the heart, blood, and blood vessels
Circulatory system
It is the most essential part of the circulatory system, it is an involuntary muscular organ that pumps blood
Heart
It sends blood to the lungs for oxygenation, it also sends blood to the digestive system for nutrients
Heart
Fluid that carries oxygen and nutrients to all parts of the body. It is the only fluid that circulates all over your body.
Blood
The only way to transmit nutrients and oxygen to the body. Your body needs this to function since it supplies oxygen and nutrients to the body.
Blood
The heart is enveloped by the _____?
Lungs
TRUE OR FALSE: The heart is found in the medias tinum
True
TRUE OR FALSE: The heart extends from the second rib to about the level of the seventh rib
FALSE
TRUE OR FALSE: The heart is slightly left of the midline
True
TRUE OR FALSE: In heart models, blue blood vessels represent oxygenated blood
False
The heart is protected LATERALLY by the _____?
Lungs
The heart is protected POSTERIORLY by the _______?
Vertebral Column
The heart is protected ANTERIORLY by the _______?
Sternum
It covers the heart and large blood vessels attached to the heart
Pericardium
It is the innermost layer of the pericardium
Visceral Pericardium
It is the layer on top of the visceral pericardium
Parietal Pericardium
It is the outermost layer of the heart walls that is composed of fat to cushion the heart
Epicardium
It is the middle layer of the heart walls. It is primarily cardiac muscle
Myocardium
The innermost layer of the heart walls. It is thin and smooth and stretches as the heart pumps
Endocardium
Receiving chambers of the heart
Atria
Pumping chambers of the heart
Ventricle
It receives oxygen-poor blood
Right atrium
It receives oxygen-rich blood
Left atrium
Which septum divides the atria
Interatrial septum
It pumps blood to the lungs
Right ventricle
It pumps blood to the body
Left ventricle
What septum divides the ventricles
Interventricular septum
What valve is located between the RIGHT ATRIUM AND RIGHT VENTRICLE
Tricuspid valve
What valve is located in the LEFT ATRIUM AND LEFT VENTRICLE
Bicuspid valve
What valve prevents backflow from the lungs
Pulmonary valve
What valve prevents backflow in the aorta
Aortic valve
TRUE OR FALSE: the atria is bigger than the ventricles
False
It is a passageway/pathway for blood
Blood vessels
Biggest blood vessel
Artery
Medium blood vessel
Veins
Smallest blood vessels
Capillaries
It is the smallest artery/small branches of arteries
Arterioles
The strongest and biggest blood vessels that carries blood away from the heart.
Arteries
It is the largest artery that takes blood directly from the heart to the body
Aorta
It carries blood back to the heart
Veins
Small vessels formed when capillaries merge
Venules
It is the largest vein that carries blood to the right atrium
Vena cava
It is the braches of arterioles. It is the smallest type of blood vessels. It connects arterioles to venules and it only about one cell layer thick. It is where oxygen and nutrients pass into a body cell. It is where exchanging of oxygen and nutrients takes place
Capillaries
Tip of the heart
Apex
Scientific name of red blood cells
Erythrocytes
Scientific name of white blood cells
Leukocytes
These are cell fragments found in the blood
Platelets
Fluid part of the blood
Plasma
TRUE OR FALSE: percentage of red blood cells in an average human is about 45%
True
TRUE OR FALSE: Percentage of white blood cells and platelets in the blood is 1%
True
TRUE OR FALSE”Percentage of plasma in the blood is 55%
True
It is a small biconcave-shaped cells that transports oxygen throughout the body
Erythrocytes
It is the pigment in red blood cells
Hemoglobin
Part of RBCs that carries oxygen and is bright red
Oxyhemoglobin
Part of RBCs that does not carry oxygen and is bright red
Deoxyhemoglobin
Type of blood cell that fights infections
Leukocytes
Part of WBCs that destroys bacterias and toxins in the bloodstream
Neutrophils
Part of WBCs that gets rid of parasitic infections such as worm infections
Eosinophils
Part of WBCs that controls inflammatory and allergic reactions
Basophils
TRUE OR FALSE: WBCs has irregular shapes
True
Foreign body in your body
Pathogens
Part of Agranulocytes that destroys bacteria, viruses, and toxins in the blood
Monocytes
Part of Agranulocytes that provides immunity for the body
Lymphocytes
Fragments of cells found in the blood stream. It is important in the clotting process of the body
Platelets
Scientific name of platelets
Thrombocytes
Liquid portion of the blood mostly composed of water
Plasma
Protein that is needed for blood clotting
Fibrinogen
Part of bleeding control that controls bleeding
Hemostasis
Biggest blood cell
Leukocytes
Smallest blood cell
Thrombocytes
It is the clumping of blood
Agglutination
It carries viruses and infection and is found in RBCs
Antigen
It fights antigens and is found in the plasma
Antibodies
Universal blood type donor
O
Universal blood type recipient
AB
