Question | Answer |
---|---|
Site of blood cell formation,Stores minerals | Skeletal System |
Maintains posture,produces heat, Allows manipulation of the environment, locomotion, and facial expression. | Muscular System |
Composed of red bone marrow,thymus, spleen, lymph nodes,and lymphatic vessels. Picks up fluid leaked from blood vessels and returns it to blood. | Lymphatic System |
Composed of kidneys, ureters,urinary bladder, and urethra. Regulates water, electrolyte,and pH balance of the blood. | Urinary system |
away from the midline | lateral |
divides the body into anterior and posterior parts | Frontal or coronal |
While the circulatory system circulates the blood cells, the ----- produces blood cells. | skeletal system |
Heartburn, or gastric reflux, is most often felt in the | epigastric region |
Cervical | Neck |
Coxal | hip |
Acromial | Point of shoulder |
Buccal | cheek |
Plantar | SOLE |
Inguinal | GROIN |
Olecranal | Back of elbow |
The lower middle portion of the abdomen | Hypogastric region |
The upper middle portion of the abdomen | Epigastric region |
The abdominal regions that are lateral to the hypogastric region | Right and left inguinal regions |
The abdominal regions that are lateral to the umbilical region | Left and right lumbar regions |
The abdominal regions that are lateral to the epigastric region | Right and left hypochondriac regions |
contains the kidneys, ureters, stomach, intestines, liver, gallbladder, and pancreas | abdominal cavity |
contains the lungs and heart. | THORACIC CAVITY |
contains bladder, anus and reproductive system. | PELVIC CAVITY |
Crural | LEG |
Antebrachial | Forearm |
unique substances that cannot be broken down by ordinary chemical means | ELEMENTS |
consists of neutrons and protons | The nucleus |
equal to the number of protons (and electrons) | Atomic number |
equal to the mass of the protons and neutrons | MASS NUMBER |
atoms with same number of protons but a different number of neutrons | ISOTOPES |
two or more atoms held together by chemical bonds | MOLECULE |
two or more different kinds of atoms chemically bonded together | COMPOUND |
are charged atoms resulting from the gain or loss of electrons | IONS |
are formed by the sharing of two or more electrons | Covalent bonds |
Too weak to bind atoms together, Common in dipoles such as water | HYDROGEN BONDS |
Synthesis reactions which always involve bond formation A + B AB | Combination reactions |
Molecules are broken down into smaller molecules AB A + B | Decomposition reactions |
Bonds are both made and broken AB + C ---AC + B | Exchange reactions |
Systems that resist abrupt and large swings in the pH of body fluids | BUFFERS |
glucose, ribose, deoxyribose (DNA), galactose, fructose | Monosaccharides |
Formed when 2 monosaccharides are joined by dehydration synthesis (ex.) sucrose (table sugar), lactose (in milk), and maltose (malt sugar) | DISACCHARIDES |
Long chains of simple sugars linked together by dehydration synthesis, ex STARCH, CELLULOSE, GLYCOGEN | POLYSACCHARIDES |
All matter, living or not, is made up of An element is made up of only one kind of | ATOMS |
The number of protons in the nucleus of an atom is called the | atomic number |
When an atom gives or accepts extra electrons it becomes charged and is called an | ION |
Two elements can combine to form a | MOLECULE |
contain carbon, hydrogen, and oxygen and are considered the most abundant type of biomolecule. | Carbohydrates |
