ANAT & PHYS I: The human body and chemistry

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
