Life Of A Red Blood Cell

FUNCTIONS OF A RBC

• The main function of RBC are to transport oxygen and carbon dioxide.
• The shape of a RBC is a excavated disk with a flattened center
• The size of human RBC is 6.2-8.2um.

BIRTH OF A RBC

• The production of RBC is produced primarily by the kidneys.
• RBC start as bone marrow and then after maturing they are released.
• In to the blood stream.
• RBC have no nucleas and can change shape.
• RBC only live about 120 days.

PATH OF A RBC

• Deoxygenated blood enters the right atrium
• Through the inferior vena cava and the superior vena cava.
• The blood goes from the right atrium to the right ventricle then
• Goes through the tricuspid valve after that it flows through the
• Pulmonary artery that carries it to the lungs, then it is oxygenated.q

RBC GAS EXCHANGE

• Blood flows to the capillaries surrounding lung alveoli.
• The oxygen is released into the alveoli sacs into the blood
• Within the surrounding capillaries.
• Molecules in the RBC release carbon dioxide picked up from the
• Body tissues and become saturated with oxygen.

PATH OF RBC

• The pulmonary veins enter the left atrium.
• The When the left atrium relaxes, the oxygenated blood drains into the left ventricle
• Now the heart really squeezes. As the left ventricle contracts,
• The oxygenated blood is pumped into the main artery of the body the aorta.

WHERE DOES IT GO?

• After the blood leaves your heart it goes and gives
• And pumps blood throughout your whole entire body.

DEATH OF A RBC

• The life of a RBC is only about 120 days.
• The thing that destroys RBC is Hemolytic Anemia.
