The lymphatic, or immune, system is made up of
the lymph nodes, the thymus gland, the spleen, and the
lymph vessels (see Figure 1-8). Its function is to drain
tissue spaces of excess interstitial fluids and absorb fats
from the intestine and carry them to the blood. It also
protects the body from disease by developing immu-nities
and destroying most invading disease-causing
microorganisms.
The respiratory system is composed of the nasal
cavi-ties, pharynx, larynx, trachea, bronchi, and lungs (see
Figure 1-8). It brings oxygen to and eliminates carbon di-
oxide from the blood.
The digestive system includes the alimentary ca-nal
(mouth, esophagus, stomach, small and large in-testines,
rectum, and anus) with its associated glands (salivary, liver,
and pancreas) (see Figure 1-8). Its function is to convert
food into simpler substances that along with other nutrients
can be absorbed
