Cardio vascular system
Mikaela Hernandez
per.5
Major components and functions of blood
Composition of blood
-Matrix:non living fluid (Plasma)
-Formed elements:
-Erythrocytes:Red Blood cells(45%)
-Leukocytes:White blood cells (<1%)
-Platelets (55%)
Functions
Transport:blood delivers O2 and nutrients to cells as well as moves hormones from endocrine to target organs
Regulation: maintains body temp, buffers like akaline reserve, and fluid vol.
Protections:prevents blood loss(plasma proteins),prevents infections (immunity in blood)
Disorders of the cardio vascular system
Peripheral Artery Disease:arteries narrowed and reduce blood flow:Caused by smoking and obesity.Treated by Medications.
Cerebrovascular accident :interupted blood flow to portion of brain.Caused by blood clot in artery or aneurysm.Treated by physical therapy and/or lifestyle changes
Myocardial Infarction(Heart attack):Blocked blood flow to part of the heart.May be caused by blood clots or stress.May be treated by lyfestyle change
Endocarditis and Myocarditis:imflamation of heart, Caused by virus, or recent surgery,Treated by antibiotics and/or reduced activity.
Congenital Heart Disease:issue with structure of heart beginning at birth,Caused by aortic stenosis and/or tricuspid Artesia, treated by Medication and/or healing on its own.
Major functions of the cardio vascular system
delivers oxygen,nutrients,hormones,ect. to cells and organ in the body.
ABO, Rh blood types
Blood groups:AB,B,A,O
AB is universal recipient and O is universal donor
Rh factor is protein positive means you have the protein and negaive meaning you dont
Major blood vessels
pulmonary trunk:connects to pulmonary vale and is main arterial branch
pulmonary veins:bring oxygenated blood from lungs to heart
Aorta:carries blood from the heart to the rest of the body
Venacava:superior and inferior:brings deoxygenated blood to the heart
Compare and contrast arteries, veins , and capillaries
Arteries:carry blood away from the heart most blood is oxygenated except for pulmonary circulation and umbilical vessels of fetus.
Capillaries:direct contact with tissue cells
Veins:Carry blood to heart and can be superficial and deep unlike arteries
Cardiac Muscle cycle and ECG
ECG:is a graphic recording of electrical activity
1)Sinoatrial node
2)Atrioventricular node
3)Atrioventricular bundle
4)right and left branches
5)subend conductiong network
Anatomy of the heart
Valve:aortic,mitra,tricuspid,pulmonary
Chambers:right atrium and ventricle and left atrium and ventricle
Blood vessels:superior venacava,aorta,pulmonary trunk, pulmonary veins, inferior vena cava
Layers of the heart
epicardium
endocardium
myocardium
Blood Flow
2:Right atrium
3:Tricuspid Valve
1)Superior/Inferior Vena cava
4:Right Vetricle
11:Aortic Semilunar arteries
8:Pulmonary veins
7:Lungs
9:Left atrium
6:Pulmonary Arteries
10:Bicuspid/Mitral Valve
5:Pulmonary Semilunar valve
12:Aorta
Vital signs(Pulse,blood pressure,body temp.,and respiratory rate)
Pulse:Throbing of arteries(taken with radial pulse and pressure points)
Blood pressure:force per unit area exerted on wall of the heart.(using a sphygmomanometer)
