Nathaniel Matulessya Period 2 Cardiovascular
Major components and functions of Blood
Formed elements
Platelets
RBC
WBC
Neutrophils
Has 50-7 0% of leukocytes
Eosinophils
Make up 1-3% of circulating leukocytes
Basophils
Has <1% of leukocytes
Monocytes
Make up 3-9% of circulating leukocytes
Lymphocytes
Live many years and has 25-33% of circulating leukocytes
Plasma
Electrolytes
Water
Proteins
Albumin
Globulins
Fibrinogen
Wastes
Nutrients/Hormones/Vitamins
Gasses
N2
O2
CO2
Function
Blood transports substances throughout the body, helps to
maintain homeostasis and distributes heat
Blood transports nutrients and oxygen to the body cells, and
removes metabolic wastes and carbon dioxide
ABO, Rh blood types
A blood
Antigen A
Antibody B
B blood
Antigen B
Antibody A
AB blood
Antigen A and B
Neither A/B
If blood has Antigen D = RH positive.
If blood doesn't have Antigen D = RH negative
O blood
Antibody A & B
Neither A/B
Major functions of the cardiovascular system
Functions
Blood goes through the vessels throughout the body to give individual cells with oxygen and nutrients metabolic waste.
Anatomy of the heart (including all chambers, and valves)

Blood flow through the body
After the blood goes through the heart it then goes up to your head and goes all throughout your body. When it cycles back, it goes into the Superior/Inferior vena cava and does the blood flow in the heart once again.
Structural and functional differences between blood vessel types (arteries, veins,
capillaries)
Arteries
Carry oxygenated blood away from the heart. Arteries branch and re-branch, becoming smaller. Arteries feed oxygenated blood to the capillaries. The aorta is the largest artery in the body, taking blood from the heart, branching into other arteries that send oxygenated blood to the rest of the body.
Capillaries
Distribute the nutrients and oxygen to the body's tissues and remove deoxygenated blood and waste. They connect the arterioles with the veins.
Veins
Carry blood back to the heart. The vein walls are similar to arteries but thinner and less elastic. Veins carry deoxygenated blood towards the lungs where oxygen is received. The pulmonary veins then carries this oxygenated blood back to the heart.
Cardiac cycle and the ECG
Circulates Oxygen and removes Carbon Dioxide
Gives cells nutrients
Removes the waste products of metabolism to the organ that disposes of those wastes
Protects the body from infections
Blood clots stop bleeding from injuries
Sends hormones to target cells and organs
Regulates body temperature
Major blood vessels (names arteries and veins)
Aorta
Superior Vena Cava
Inferior Vena Cava
Pulmonary Artery
Vital signs (BP and Pulse)
BP moves blood through lumen of arteries and arterioles
Arterial blood pressure
Systolic Pressure
max arterial pressure reached during ventricular contraction
Diastolic prtessure
Minimum arterial pressure reached during ventricular relaxation
BP is not greater that 120/80 at rest is considered normal
Cardiac output
Affect BP
Stroke volume
Amount of blood discharged from each ventricle with each contraction
Heart rate
number of heart beats per minute
The alternating expansion and recoil of wall of an artery as the ventricles contract and relax can be felt at a certain point in the body as a pulse
Common pulse point = radial artery
Disorders of the cardiovascular system
Abnormal heart rhythms
Your heart beast out of rhythm.
Aorta disease
The aorta widens or tears.
Heart disease
A problem in one or more parts of the heart.
Heart failure
Your heart doesn't pump as strongly as it should.
Stroke
Something that slows or blocks blood flow to your brain.
Vascular disease
A condition that affects your circulatory system.
