Marisa Alberto Period: 3 Cardiovascular System - Coggle Diagram
Marisa Alberto Period: 3 Cardiovascular System
Vital signs
heart heart- response to the autonomic nervous system
Electrocardiogram- recording of the electrical changes that occur during a cardiac cycle
Arterial blood pressure- rises and falls according to a pattern
established by the cardiac cycle
ABO, Rh blood types
Type B blood- B antigens on RBC
Type AB blood-A and B antigens on RBC and neither type of antibodies
Type A blood- A antigens on RBC and anti-B in plasma
Type O blood-neither antigen on RBC and both
types of antibodies
Rh negative-blood is absent
Rh positive-blood is present
Structural and functional differences between blood vessel types
a part of that makes up the circulatory system
carries blood away from the heart, to the cells, and back again
Anatomy of the heart
right ventricle- pulmonary semilunar valve and pulmonary arteries
left atrium- pulmonary vein and bicuspid valve
right atrium- superior vena cava and tricuspid valve
left ventricle- aortic semilunar valve and aorta
Blood flow through the heart and blood
Pulmonary circuit-blood flow between heart and lungs
Systemic circuit-blood flow between heart and body tissues
proceeds in a continuous circle
Major Components & functions of Blood
-Blood transports nutrients and oxygen to the body cells
-removes metabolic wastes and carbon dioxide
-transports substances throughout the body
-contains red blood cell, white blood cells, platelets, and plasma
Major functions of Cardiovascular
-nutrients to tissues
-removing wastes
-supplying oxygen
Layers of heart
Myocardium- middle layer it pump bloods out of the chambers
Endocardium-inner layer it contains the purkinje
Epicardium-outermost layer it decreases friction in the heart
Cardiac cycle and ECG
ECG-recording of electrical changes that occur during a cardiac cycle
Cardiac Cycle- 1. Atria contract while ventricles relax 2. Then ventricles contract while atria relax 3. Then entire heart relaxes for a moment
Major blood vessel
Venules-leading from capillaries merge to form larger
Capillaries-blood vessels with the smallest diameter
Veins-return blood to the heart
Arterioles-wall of
Arteries-strong and elastic vessels adapted for carrying high-pressure blood
Disorders
myocardial Infarction- blood flow to part of the heart is blocked
Cerebrovascular- blood flow to a portion of the brain is interrupted
Congenital heart disease- issue with heart structure and/or function present from birth.
