ANAT & PHYS I: The human body and chemistry
| 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 |
