Cardiovascular System Sierra Diaz P.2 - Coggle Diagram
Cardiovascular System Sierra Diaz P.2
Major Components/ functions of blood :!:
RBC (erythrocytes)
- produced in bone marrow & carry oxygen from the lungs and deliver throughout our body. (used in diagnosing conditions/diseases)
WBC (leukocytes)-
protect body from infection/fights diseases
Plasma
- fluid matrix (formed elements) that helps removes waste & carries ALL parts of blood throughout circulatory system
Platelets-
stoppage of bleeding
Granulocytes
= granular cytoplasm(short-life span)
Neutrophils
= 50%-70% of WBC (strong)
Eosinphils
= 1-3% of WBC (kills parasites/moderate inflammation)
Basophils
= 1% of WBC (promote inflammation)
Agranulocytes
= don't have granular cytoplasm (longer life-span)
ABO/ Rh Blood types
Type A
= A antigens + anti-B antibodies in plasma
Type B
= both A&B antigens + NO bodies in plasma
Type B=
B antigens + anti-A bodies in plasma
Type O
= NO antigens + BOTH antibodies in plasma
Universal recipient= (Type AB)
Universal Donor= (Type O)
BOTH CAN RECEIVE ALL 4 BLOOD TYPES
Rh= positive or negative
(rhesus factor) found on surface of RBC. If RBC have
protein
, then Rh POSITIVE, if RBC have NO protein, then RH NEGATIVE
Rh+
= Antigen D is PRESENT
Rh-
= Antigen D is ABSENT Transfusion/pregnancy ONLY way Rh+ can come in contact w Rh-
Major Functions of CVS
+ Anatomy, layers, blood flow
❤
chambers/valves
4 IN TOTAL 2 upper chambers (atria) & 2 lower chambers (ventricles)
Atria
= receives blood
Ventricles
= pump blood
Interventricular Septum= separates RV from LV
SVC & IVC= bring blood back to RA
LV= pumps blood to aorta
Walls/Layers of
❤
Epicardium
= outermost layer
Myocardium
= middle layer
Endocardium
= inner layer
Blood Flow throughout heart & body
RIGHT
SVC /IVC
Right Atrium (RA)
Triscupid Valve (TV)
Right Ventricle (RV)
Pulmonary Vave (PV)
Pulmonary Artery (PA)
Lungs
LEFT
Pulmonary Veins (PV)
Left Atrium (LA)
Mitral Valve (MV)
Left Ventricle (LV)
Aortic Valve (AV)
Aorta
Blood Vessels
Capillaries-
transport blood between arteries & veins (connect arteries to veins)
Venules & veins
- receive blood from capillaries & carry blood back to heart
Arteries
- carry blood away from heart (strongest/largest)
Cardiac Cycle/ ECG
Systole
= period of contraction (atrial systole & ventricular systole)
ECG ( Electrocardiography)
- records to show how fast heart is beating, rhythm of heart beats, strength and timing of the electrical impulses (changes in the ECG= heart-related condition)
Diastole
= period of relaxation (atrial diastole & ventricular diastole)
Vital Signs (BP/pulse)
Vital Signs=
Body Temperature
Pulse Rate
Respiration Rate
Blood Pressure
Blood Oxygen
Weigh.
Blood Glucose Level
Normal BP
= between 90/60 and 120/80
Normal Pulse
= 60 to 100 beats per min
Major BV
Pulmonary Veins (PV)
- carry oxygen-rich blood from your lungs to heart (moves blood between heart & lungs) blood goes to LA
Superior Vena Cava (SVC)
- carries blood from head, neck, arms, and chest to heart into LA (returns deoxygenated blood to RA) located next to right side of sternum/ RA
Pulmonary Trunk/Artery( PT)-
transports deoxygenated blood from RV to lungs
located at base of RV of heart ( splits into the left and right pulmonary arteries to provide blood for oxygenation into lungs)
Inferior Vena Cava (IVC)-
carries blood from the legs, feet, and organs in the abdomen and pelvis (located in lower back and runs thorough heart)
Aorta-
(largest vessel)- transports oxygen-rich BV to heart/bod & begins in LV of heart
supplies blood to stomach, liver, pancreas, spleen, small and large intestines, kidneys, & reproductive glands
Cardiovascular Disorders
Peripheral Arterial Disease-
disease of blood vessels supplying the arms and legs
Cerebrovascular Disease-
disease of the blood vessels supplying the brain
Coronary Heart Disease-
disease of the blood vessels supplying the heart muscle
