Leukemia
Leukemiais a cancer of the blood or bone marrow. It is characterized by an abnormal
production of blood cells, usually white blood cells. Lymphomais a type of cancer in
white blood cells calledlymphocytes.There are many types of lymphoma.
Hemophilia
Hemophiliais the name of a group of sex-linked (X-linked) hereditary diseases that affect
the body’s ability to control blood clotting (see theGeneticschapter). Hemophilia is caused
by a lack of clotting factors in the blood. Clotting factors are needed for the normal clotting
of blood. A person who has hemophilia is initially able to make a clot to stop the bleeding,
but because fibrin is not produced, the body is unable to keep a clot at an injury site. The
risk of internal bleeding is also increased in hemophilia, especially into muscles, joints, or
bleeding into closed spaces.
Lesson Summary
- Blood is a colloidal solution that contains red blood cells, white blood cells, and
platelets. The cells are suspended in plasma. The red blood cells give blood its red
color. Blood carries oxygen and nutrients to body calls and carries wastes away. It also
helps to maintain body temperature and to carry chemical messages calledhormones
around the body. - Hemoglobin is the oxygen-carrying protein that is found in red blood cells. White
blood cells defend the body against infection by bacteria, viruses and other pathogens.
