Cardiovascular System Deven Gasca (P.2)
Cardiovascular system
Structure: The heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries
Term: Pertaining to the heart and blood vessels that make up the circulatory system
definition: The system that contains the heart and the blood vessels and moves blood throughout the body
Structural and functional difference of blood vessels
Veins
Definition: A tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.
Structure: A vein is made of three layers of tissues and fibers: The tunica adventitia gives structure and shape to your vein. The tunica media contains smooth muscle cells that allow your vein to get wider or narrower as blood passes through.
Arteries
Structure: Each artery is a muscular tube lined by smooth tissue and has three layers such as the intima, the inner layer lined by a smooth tissue called endothelium.
Definition: Any of the muscular-walled tubes forming part of the circulation system by which blood
Capillaries
Definition: Any of the fine branching blood vessels that form a network between the arterioles and venules.
Structure: Capillaries contain two layers of cells the endothelial cells are inside the capillary
Blood vessels
Vein
Definition: Any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.
Structure: Veins have thinner walls and use valves to keep your blood flowing
Capillaries
Structure: Capillaries contain two layers of cells: Endothelial and Epithelial cells
Definition: Any of the fine branching blood vessels that form a network between the arterioles and venules
Arteries
Structure: Arteries have thick walls with muscle tissue
Definition: A blood vessel that carries blood from the heart to tissues and organs in the body.
Layers of heart
Myocardium
Definition: The muscular tissue of the heart.
Structure: Make up the middle and thickest layer of the heart wall
Term: The middle muscular layer of the wall of the heart.
Endocardium
Structure: The endothelial layer, the inner connective tissue layer, the elastic tissue layer, the smooth muscle cell layer, and the outer connective tissue layer or subendocardial layer
Term: The lining of the interior surface of the heart chambers
Definition: The thin, smooth membrane which lines the inside of the chambers of the heart and forms the surface of the valves.
Epicardium
Structure: Composed of mesothelial cells, fat, and connective tissue
Term:a serous membrane that forms the innermost layer of the pericardium and the outer surface of the heart.
Definition: An evolutionarily conserved layer of mesothelium covering the outermost cell layer of the vertebrate heart
Cardiac cycle and ECG
Cardiac Cycle
Structure:The cardiac cycle has 3 stages: Atrial and Ventricular diastole also Atrial systole
Term: Diastole and systole
Definition: Is the performance of the human heart from the beginning of one heartbeat to the beginning of the next.
ECG
Structure: There are three main components to an ECG: the P wave, which represents depolarization of the atria; the QRS complex, which represents depolarization of the ventricles; and the T wave, which represents repolarization of the ventricles.
Term: A line graph that shows changes in the electrical activity of the heart over time
Definition: A record or display of a person's heartbeat produced by electrocardiography.
Blood types
Rh blood
Definition: Is a human blood group system
Structure: The Rh locus is located on the long arm of chromosome
Term: Rhesus factor
ABO blood
Structure: Image result for abo blood group structure
The ABO blood group antigens are attached to oligosaccharide chains that project above the RBC surface
Term: A system used to group human blood into different types, based on the presence or absence of certain markers on the surface of red blood cells
Definition: The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes.
Vital signs
Pulse
Definition: The number of times the heart beats within a certain time period, usually a minute
Term: A rhythmical throbbing of the arteries as blood is propelled through them
BP
Term: The force of circulating blood on the walls of the arteries.
Definition: The pressure of the blood in the circulatory system
Heart
Valve
Bicuspid Valve
Structure: A circle divided into thirds.
Defintion: An aortic valve with only two cusps
Mitral Valve
Definition: The valve between the left atrium and the left ventricle of the heart, consisting of two tapered cusps.
Structure: Composed of the left atrial wall, left ventricle wall, the mitral annulus, the anterior and posterior leaflets, chordae tendinae and papillary muscles
Triscupid Valve
Structure: Consists of three leaflets: anterior, posterior, and septal
Definition: valve flaps open to let blood flow from the upper right chamber
Aortic Valve
Definition: One of four heart valves and is the final one encountered by oxygenated blood as it leaves the heart
Structure: Typically made up of three membranes (cusps) made up mainly of collagen
Chamber
Vena Cava
Structure: Two parts: the superior vena cava and the inferior vena cava
Term: A large vein that carries blood to the heart from other areas of the body.
Definition: A large vein carrying deoxygenated blood into the heart
Pulmonary Vein
Structure: Four pulmonary veins, with two connected to each lung
Term: Any of the veins that carry blood with high levels of oxygen from the lungs to the left atrium of the heart.
Definition: A vein carrying oxygenated blood from the lungs to the left atrium of the heart.
Aorta
Structure: Cane-shaped artery
Term: The largest artery in the body
Definition: The main artery of the body, supplying oxygenated blood to the circulatory system.
Right/left Vertical
Structure :A wall of muscle called the septum separates the left and right atria and the left and right ventricles
Definition: The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle
Right/Left Atrium
Structure: Image result for right and left atrium structure
There are two pouches which comprise the right atrium, the main cavity, and also a small chamber projecting to the left
Definition:The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lung
Disorders of Cardiovascular system
Heart Attack
Term: Myocardial infarction
Definition: Blood flow to part of the heart blocked
Congenital Heart
Definition: Issue with heart structure and function present form birth
Endocarditis and Myocarditis
Definition: Inflamtion of the heart
