Tubercles ✔Correct Answer-Small, rounded processes that provide the attachment for tendons
and muscles.
Blood path ✔Correct 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 ✔Correct 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 ✔Correct Answer-air sacs in the lungs
Diaphragm ✔Correct 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 ✔Correct Answer-A muscular tube that connects the mouth to the stomach.
Pancreas ✔Correct 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 ✔Correct Answer-A muscular sac attached to the liver that secretes bile and stores it
until needed for digestion
small intestine ✔Correct 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 ✔Correct 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? ✔Correct Answer-lymph nodes, thymus gland, spleen, tonsils
and adenoids
lymph nodes ✔Correct 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 ✔Correct 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 ✔Correct 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 a blood filter that
func- tions in the immune system to decrease susceptibility and fight off infection.
the master gland ✔Correct Answer-pituitary gland
pancreas ✔Correct Answer-an organ playing roles inthe digestive and endocrine systems,is an
endocrine gland that secretes thehormones insulin and glucagon for bloodsugar regulation
sagittal plane ✔Correct Answer-a vertical plane that divides the body into right and left parts,
flexion/extension, (squat, curl, lunge, walk)
frontal plane ✔Correct Answer-Divides the body into front and back portions,
adduction/abduction, (lat raise, pulldown, side bend, military press)
transverse plane ✔Correct Answer-horizontal division of the body into upper and lower portions,
internal/external rotation, rotation at waist
spine ✔Correct Answer-cervical(7 vert) thoracic (12 vert) lumbar (5 vert) sacral (sacrum 4-6 vert,
coccyx 3-5 vert)
most common knee injury ✔Correct Answer-knee
quad muscles ✔Correct Answer-rectus femoris, vastus lateralis, vastus medialis, vastus
intermedius
back muscles ✔Correct Answer-latissimus dorsi, teres major, rhomboids, traps, erector spinae
Epimysium ✔Correct Answer-a sheath of fibrous elastic tissue surrounding a muscle.
Endomysium ✔Correct Answer-Connective tissue surrounding a muscle fiber
myofibrils ✔Correct Answer-Myofibrils are the contractile components that allow for strength and
performance of the muscles, they are composed of repeating sarcomeres that giveskeletal muscle
cells a striated look, thus thename 'striated muscle'
Sarcomere ✔Correct Answer-he functional units of skeletal muscle occurring in repeating
segments along the myofibril,
Sarcoplasmic Reticu- lum releases calcium ions during muscle contraction, and absorbs them during
relaxation. ✔Correct Answer-
