AHS 100 Chapter 8: The Blood and Lymphatic Systems- Hematology and
Immunology
❏The blood carries signals from others parts of the body allowing for
communication. The blood also takes away the waste made by the
body’s cells. The lymphatic system provides constant protection by
repairing injuries and fighting infections
❏8.1 Word Parts Associated with the Hematological/Immunological
Systems
❏Blood has three main types of cells: red blood
cells(erythrocytes) they are the transporters that bring oxygen
to all the cells of the body and take away the waste. White
blood cells(leukocytes) fight infections. Platelets(thrombocytes)
are the small scab- makers of the body who patch things up.
❏Red blood cells are the most common cells in the blood, they
contain the substance hemoglobin. Hemoglobin grabs onto
oxygen when the surrounding oxygen levels are high and
releases it when the ambient oxygen levels are low. They help
carry fresh oxygen from the lungs to all the parts of the body
that need it.
❏White blood cells protect the body from invasion. The blood
contains different types of white blood cells that fight different
types of infections(neutrophils, lymphocytes, basophils, and
eosinophils). The body also makes special protective proteins
as well called immunoglobulins. Different types of
immunoglobulins are designed for specific tasks, usually
immunizations are means of forcing the body to make
immunoglobulins against dangerous illnesses.
❏Platelets patch up any broken blood vessels. Blood vessels
constantly develop small leaks, they need a patch system to
keep them functioning properly. When a vessel is injured, it
attracts platelets that clump together to form a sticky patch
and send signals that help further form a permanent clot.
