Avg of 5L in adults
Function of the Blood
- transports O2 , nutrients, chemical messengers to all cells of the body
- fight infection
Components of blood
55% plasma
&
45% WBC, RBC & platelets
RBC’s
Aka erythrocytes
- carry o2 and contain hemoglobin
- with o2 red and with CO2 dark red
WBC’s
Aka leukocyte
FIGHT INFECTION
Platelets
Aka thrombocytes
-responsible for clotting
LIVES FOR 7-8days
Eosinophil
Defence against parasites
Neutrophil
Lives up to 7hrs
Immune defence
Basophil
Inflammatory response
Plasma
Contains fibrinogen
Prothrombin
Calcium

DEAD
Ischemic stroke
blood clot
(headache weakness seizure)
thrombolytic (after Mri
if clot is in a lartger artery will need thrombectomy
Hemorrhagic stroke
Invasive surgery to Bleeding
Noninvasive surgery to create a clot this technique involves passing a catheter through a series of arteries to the site of bleed and filling it with a nest of wire the wire left behind to collect the blood cells and corn factors to stop before you
CHF
Inability of the heart to keep up with the body demands for oxygen and nutrients
One or both ventricles may fail to to the cause of loss contractility
Causes veins behind her to become congested
Early CHF
Increased sympathetic activity competency to be decreased blood flow by increasing heart rate
Kidneys compensate for the reduction by reduced blood flow by retaining sodium and water to increase blood flow
Symptoms of CHF
Exercise
Fatigue
Decreased BP
cyanosis
Diagnosis CHF
Echocardiogram
