Circulatory System

Oxygenated Blood

Blood that is high in oxygen (left side of the heart)

Deoxygenated Blood

Blood that is low in oxygen (right side of the heart)

Red blood cells

One of the components of blood. Carry oxygen and carbon dioxide to and from the heart. Drop off oxygen through the body.

White blood cells

One of the components of blood. Protects the body of infectious disease and foreign invaders.

Platelets

One of the components of blood. Help wounds heal and prevents bleeding by creating blood clots.

Plasma

The liquid component of blood. Contains nutrients and helps the other components of blood travel through the blood vessels

Heart Rate

The number of heartbeats per minute. The heart rate is based on the number of contractions of the ventricles (the lower chambers of the heart)

Blood Types

A, B, AB, & O. O is recessive to all other blood types. AB= Universal recipient; O= Universal Donor.
A- contains the A antigen
B- contains the the B antigen
AB- contains the A & B antigens
O- does not contain any antigens

Coagulation

The clotting of blood

Arteries

Moves blood away from the heart

Veins

Moves blood towards the heart

Capillaries

The smallest blood vessels that connect the veins and arteries. O2 and CO2 is able to pass through the walls of the capillaries . O2 is transferred to the organs; CO2 diffuses to lungs

Right atrium

One of the 4 chambers of the heart. Deoxygenated blood enters the right atrium through the inferior and superior vena cava.

Right Ventricle

The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs. The right ventricle is one of the heart's four chambers. It is located in the lower right portion of the heart below the right atrium a

Vena Cava Veins (Superior & Inferior)

The inferior vena cava is the inferior of the two venae cavae, the large veins that carry deoxygenated blood from the body into the right atrium of the heart.

Tricuspid Valve

Valve that is situated at the opening of the right atrium of the heart into the right ventricle and consists of three triangular membranous flaps

Pulmonary Artery

Carries deoxygenated blood from heart to lungs

Pulmonary Vein

Deliver oxygen rich blood from the lungs to the left atrium

Pulmonary Semilunar Valve

Heart valve opening from the right ventricle to the pulmonary artery

Left Atrium

Chamber that receives oxygenated blood from the pulmonary veins and pumps it into systemic circulation.

Left Ventricle

The chamber of the heart that receives arterial blood from the left atrium and pumps it into the aorta

Aortic Valve

The semilunar valve separating the aorta from the left ventricle that prevents blood from flowing back into the left ventricle

Aorta

The large arterial trunk that carries blood from the heart to be distributed by branch arteries through the body

Bicuspid (Mitral) Valve

Prevent blood from back flowing from the pulmonary artery into the right ventricle

Systolic Blood Pressure

the pressure created in the arteries when the left ventricle contracts and forces blood out into circulation

Diastolic Blood Pressure

the pressure remaining in the arteries when the left ventricle of the heart is relaxed and refilling

Stroke

A sudden attack of weakness or paralysis that occurs when blood flow to an area of the brain is interrupted

Leukemia

Blood condition of white cells; malignant (cancerous) condition.

Plaque

A deposit of fatty material on the inner lining of an arterial wall

Coronary Artery Disease and Heart Attack

CAD lowers the amount of blood that can pass through an artery and can result in a heart attack

Order of Blood Flow Through the Heart

1) From body 2) superior/inferior vena cava 3) right atrium 4) tricuspid valve 5) right ventricle 6) pulmonary semilunar valve 7) pulmonary artery 8) into the lungs 9) pulmonary vein 10) left atrium 11) bicuspid valve 12) left ventricle 13) aortic valve 1

Blood Type Inheritance

Universal Recipient Blood Type

Type AB

Universal Donor Blood Type

Type O

+/- Blood Type

Rh factor

Oxygenated/ Deoxygenated Blood in the Heart

Labeled Heart

Two Blood Cells Met and Fell in Love

But Alas, it was All in Vein

Left Ventricle

receives oxygenate blood from the left atrium. Sends oxygenated blood to the aortic valve to the aorta

Circulatory System

Consists of the heart, blood, and blood vessels
Circulates blood, O2 and CO2 throughout the body

Aorta

The large arterial trunk that carries blood from the heart to be distributed by branch arteries through the body.

Aortic valve

The semilunar valve separating the aorta from the left ventricle that prevents blood from flowing back into the left ventricle.

Plaque

A deposit of fatty material on the inner lining of an arterial wall
