Tubercles - answer-Small, rounded processes that provide the attachment for tendons
and muscles.
Blood path - answer-The blood that enters the right side of the heart is dark red (bluish)
and is low in oxygen; this blood travels from the right side of the heart along pulmonary
arteries to the lungs, where it receives fresh supplies of oxygen and becomes bright red.
It then flows along pulmonary veins to the heart's left side pump. Blood then leaves the
left side of the heart and travels to the rest of the body through arteries, going away from
the heart, that gradually divide into capillaries.
capillaries - answer-form a network of blood vessels between the arterioles and the
venules. In the capillaries, food and oxygen are released to the body cells, and carbon
dioxide and other waste products are returnedto the bloodstream. The blood then
travels in veins, coming back towards and into the right side of the heart; and the whole
process begins again.
Alveoli - answer-air sacs in the lungs
Diaphragm - answer-contracts it flattens, causing the chest to expand and air to be
sucked into the lungs. When the diaphragm relaxes, the chest collapses and air in the
lungs is forced out. The respiration process occurs about 12-15 times per minute, in the
healthy adult.
Esophagus - answer-A muscular tube that connects the mouth to the stomach.
Pancreas - answer-An organs in the abdominal cavity with two roles. The first is an
exocrine role: to produce digestive enzymes and bicarbonate, which are delivered to the
, small intestine via the pancreatic duct. The second is an endocrine role: to secrete
insulin and glucagon into the bloodstream to help regulate blood glucose levels.
Gallbladder - answer-A muscular sac attached to the liver that secretes bile and stores
it until needed for digestion
small intestine - answer-Digestive organ where most chemical digestion and absorption
of food takes place. These nutrients are then carried away to the liver and other body
parts to be processed, stored and distributed.
liver - answer-Blood from the intestines flows to the liver, carrying nutrients,
vitamins/miner- als, and other products from digestion. The liver stores some nutrients,
changes them from one form to another, and then releases them into the blood
according to the activities and bodily needs.
where are white blood cells found? - answer-lymph nodes, thymus gland, spleen,
tonsils and adenoids
lymph nodes - answer-Lymph nodes, distributed widely throughout the body, act as
filters - or germ traps. They contain billions of white blood cells, which multiply rapidly
to fight off invading pathogens. During illness from infection, lymph nodes fill up with
millions of extra white cells and "dead" pathogens. A noticeable swelling of the lymph
nodes may occur and can be an indication of infection.
thymus gland - answer-The thymus gland, located in front of the heart and behind the
sternum, is a special- ized organ that produces and "educates" T-cells (T-lymphocyte
cells). T-cells are orches- trated in the thymus for the purpose of attacking foreign
substances and responding to infected cells. The thymus is larger and most active
during childhood and through puberty; but, during the aging process, will slowly shrink,
eventually degenerating into tiny islands of fatty tissue.
spleen - answer-The spleen is located just behind the stomach, on the left side. It
makes and stores vari- ous kinds of white and red blood cells. Essentially, the spleen is
