Biology 11 - All About Blood Notes
RED BLOOD CELLS (Erythrocytes) – The most ________________ cells in our blood; they are
produced in the _________________________ and contain a protein called _________________________ that
carries oxygen to our cells.
WHITE BLOOD CELLS (Leukocytes) – They are part of the ________________________ and destroy
infectious agents called ________________________.
PLASMA – This is the _______________________ liquid portion of blood that contains electrolytes,
nutrients and vitamins, hormones, clotting factors, and proteins such as antibodies to fight
PLATELETS (Thrombocytes) – The ______________________________ that are carried in the plasma;
they clot together in a process called ____________________________ to seal a wound and prevent a
loss of blood.
Blood cells are made in our __________________________, which is found in certain long bones, such
as our femur.
Your blood type is established before you are ________________, by specific
_________________inherited from your parents. You inherit one gene from your MOTHER and one
from your FATHER. These genes determine your blood type by causing proteins called
___________________________________ to exist on the surface of all of your red blood cells.
The three blood types are:
The least common blood type is ________________. The most common blood type is _______________.
A ________________________________ is a procedure in which blood is given to a patient through an
intravenous (IV) line in one of the blood vessels. Blood transfusions are done to replace blood
lost during surgery or a serious injury. A transfusion also may be done if a person’s body can't
make blood properly because of an illness.
Who can give you blood?
People with __________________ blood are called ________________________, because they can give
blood to any blood type. People with ___________________ blood are called
_____________________________, because they can receive any blood type.
Scientists sometimes study _______________________________ to learn more about the human
anatomy because there are certain similarities between the two species. While studying
Rhesus monkeys, a certain blood protein was discovered. This protein is also present in the
blood of some people. Other people, however, do not have the protein. The presence of the
protein, or lack of it, is referred to as the _____________________________.
If your blood does contain the protein, your blood is said to be ____________________________. If
your blood does not contain the protein, your blood is said to be ___________________________.
The average adult has about _______________ liters of blood inside of their body, which makes up
___________ of their body weight. Blood is living tissue that carries oxygen and nutrients to all
parts of the body, and carries carbon dioxide and other waste products back to the lungs,
kidneys and liver for disposal. It also fights against infection and helps heal wounds, so we
can stay healthy. There are about __________________ red blood cells in two to three drops of
blood. For every _________ red blood cells, there are about _______ platelets and _________white
Blood is red because it contains _______________________________ and iron rich pigments.
Hemoglobin is what picks up oxygen molecules and drops off carbon dioxide molecules. _
______________________________ binds to red bloods, meaning oxygen cannot. This is how it causes
death. You can’t smell or taste it.
______________________ occurs when the blood does not have enough hemoglobin; iron makes up
______________________________________ is a genetic disease in which red blood cells become sickle
shaped, and cannot carry as much oxygen.
___________________________ is a form of cancer, in which our bone marrow makes too many white
blood cells.
