Cardiovascular System Gisselle De Jesus Per.1 - Coggle Diagram
Cardiovascular System Gisselle De Jesus Per.1
Blood flow through the heart and body
Deoxygenated blood from the body
Goes into the S/I Vena Cava
Into the Right Atrium
Into the tricuspid valve
Major functions of the cardiovascular system
Supplying oxygen
Supplying nutrients to tissues
Removing waste
Major components and functions of Blood
Major components
plasma
platelets
Red and White blood cells
Functions of Blood
helps to
maintain homeostasis and distributes heat
Blood transports substances throughout the body
Blood transports nutrients and oxygen to the body cells, and
removes metabolic wastes and carbon dioxide
Structural and functional differences between blood vessel types
Functional
Vein
Capillary
Artery

Venule
Arteriole
Anatomy of the heart
Valves
Pulmonary valve
Bicuspid/mitral
Aortic Valve
Tricuspid
Chambers
R/L ventricle
R/L atrium
S/I vena cava
Aorta
R/L pulmonary artery
Pulmonary trunk
R/L pulmonary veins
L/R atrium
L/R ventricle
Papillary Muscle
Chordae Tendineae
Intreventricular septum
ABO, Rh blood types
Rh blood types
If the Rh factor (antigen D) is absent the blood is Rh negative
If the Rh factor (antigen D) is present on a person’s red blood cells,
the blood is Rh positive
ABO
Type B blood has B antigens on RBC membranes and anti-A
antibodies in the plasma
Type AB blood has both A and B antigens on RBC membranes, but
neither type of antibodies in the plasma; universal recipient
Type A blood has A antigens on RBC membranes and anti-B
antibodies in the plasma
Type O blood has neither antigen on RBC membranes, but both
types of antibodies in the plasma; universal donor
Layers of the heart
Epicardium
Myocardium
Endocardium
Vital signs
Pulse
The alternating expansion and recoil of the wall of an artery as the ventricles contract and relax can be felt as certain points in the body
BP
moves blood through lumen of arteries and
arterioles
Disorders of the cardiovascular system
Cerebrovascular Accident
Endocarditis & Myocarditis
Peripheral Artey Disease
Congenital Heart Disease
Myocardial Infarction
Major blood vessels
Vein
Thinner wall than a artery but with similar layers
Venule
Thinner wall than in arteriole, less smooth muscle and elastic connective tissue
Capillary
Single layer of squamous epithelium
Arteriole
Thinner wall than an artery but with three layers; smaller arterioles have and endothelial lining
Artery
Thick strong wall with three layers, an endothelial lining, a middle layer of smooth muscle and elastic connective tissue, and an outer layer of connective tissue
Ecg and the cardiac cycle
Cardiac cycle
Then the ventricles contract (called ventricular systole), while
the atria relax (called atrial diastole)
Then the entire heart relaxes for a brief moment
First the atria contract (called atrial systole), while ventricles
relax (called ventricular diastole)
ECG
T Wave
Corresponds to ventricular repolarization, and leads to
ventricular relaxation
QRS complex
Corresponds to the depolarization of ventricles, which leads to contraction of the ventricles
P wave
The first wave, which corresponds to the depolarization of
the atria; this leads to the contraction of the atria
