Transcript of Blood

by: ME BLOOD Components of blood Red Blood Cells White Blood Cells Platelets What is blood? Blood Types Plasma Red Blood Cells (45%)
White Blood Cells (>1% with platelets)
Platelets
Plasma (55%) carry oxygen from the lungs to the rest of the body
take carbon dioxide back to your lungs
biconcave disc Help heal wounds by fighting infection
Ingest matter such as dead cells, tissue debris and old red blood cells. Blood is the life-maintaining fluid that circulates through the heart, arteries, capillaries and veins
They carry nourishment, Electrolytes, Hormones, Vitamins, Antibodies, Heat and Oxygen to the body tissues The function of platelets is to help clot the blood in the case of an injury. They quickly create a barrier to prevent too much blood from flowing from a wound
they send proteins to the wound to protect it from germs/infections There are 4 types of blood:
A
B
AB
O brings digested materials from the small intestine
regulates water level
carries carbon dioxide
helps to create white blood cells
fights diseases the dimple in the middle creates a larger surface area so more oxygen can be transported
more flexible and can squeeze through capillary walls Antigens Blood group antigens are carbohydrates that are attached to proteins or lipids
An antigen is a substance foreign to the body that causes an immune response. An immune response occurs when antibodies, which are proteins in your immune system, are told to attack an antigen BLOOD TYPES Blood type A: -has type A antigens
-produces antibodies against type B antigens
-can receive blood type A and O
-can donate to blood type A and AB Blood Type B: -has type B antigens
-produces antibodies against type A
-can receive blood type B and O
-can donate to blood type B and AB Blood Type AB: -has type A and B antigens
-doesn't have antibodies
-can receive from any blood type
-can only donate to blood type AB Blood type O: -has no antigens
-produces antibodies against type A and B
-can receive only blood type O
-can donate to any blood type They have different types of proteins, glycoproteins and glycolipids on the surfaces of the red blood cells and are usually inherited
