Use these flashcards to review for the Unit 3: Power test in Human Body Systems.
portion labeled a where the energy is stored.
portion labeled b, one of the nitrogenous bases.
portion labeled c, a 5 carbon sugar.
sum of all chemical activity in an organism
the amount of calories a person would burn doing nothing all day
BMR-basal metabolic rate
a calculation of body health that only takes into account the weight and height of a person.
BMI-body mass index
maintenance of a stable internal environment
enzyme that breaks down fats into fatty acids and glyceron
an enzyme that breaks down proteins into peptides in the stomach
enzymes that break down dissaccharides into monosaccharides
sucrase, maltase, lactase
enzyme in the mouth and pancreas that break down starch into dissaccharides
a process that adds water to break down large molecules into smaller ones
hydrolysis / catabolism
a process that removes water to build larger molecules from smaller ones
anabolism / dehydration synthesis / condensation
a biological catalyst, most of the time a protein that speeds up the rate of chemical reactions in a living organism
mastication, peristalsis, churning and dehydration are all examples of this.
enzymatic breakdown is an example of this type of digestion
structure labeled a site of mastication and initial chemical digestion of carbohydrates, makes a bolus to swallow
labeled b. largest internal organ, produces bile for the chemical digestion of lipids, prepares nitrogen wastes for disposal, and detoxifies poisonous chemicals in the blood.
labeled c. muscular sac in which excess bile from the liver is stored
labeled d. organ divided into cecum, ascending, transverse, descending and rectum, absorbs water and forms feces
colon or large intestine
labeled e. eliminates solid waste, defecation
labeled f. muscular tube that connects the pharynx with the stomach and does peristalsis
labeled g. saclike expansion, strong complex muscular wall that churns food and is initial site of chemical digestion of proteins
labeled h. secretes the majority of digestive enzymes into small intestine, also secretes hormones for sugar regulation into the blood
labeled i. connects the stomach with the colon, consists of duodenum, jejunum and ileum, finishes chemical digestion and absorption of nutrients from food.
c. volume of air remaining in lungs after a forced breath out
b. the total amount of air that can be forced out of the lungs after a normal exhale
expiratory reserve volume
a. the volume of air that can be forced in after a normal breath in
inspiratory reserve volume
g. The volume of air breathed in and out without conscious effort
passive transport that allows oxygen to move from the alveoli of the lungs into the capillaries and from the capillaries to the cells of the body
flow of oxygen from the outside to the alveoli
pharynx, larynx, trachea, bronchus, bronchioles, alveoli
which lung has 3 lobes
how many lobes does the left lung have?
formula for cellular respiration
O + 6CO
what happens to the diaphragm when we inhale
it contracts and moves inferiorly
what happens to the diaphragm when we exhale?
it relaxes and moves superiorly
a. cartilagenous structure that houses the vocal cords and has an epiglottis above it.
b. spongy structure that holds air
c. small branches within the lungs that carry air from the bronchi to the alveoli
d. smooth muscle structure that helps with inhalation and exhalation.
e. connects the nose to the mouth
f. cartilagenous structure that passes air from the larynx to the bronchi
h. cartilagenous tubes that branch off of the trachea to each lung.
bronchus (pl. bronchi)
j. small sacs at the end of each bronchiole where gas exchange between the respiratory and circulatory system occurs
alviolus (pl. alveoli)
hormone secreted by the pituitary gland that controls reabsorption of water in the nephrons of the kidneys
hormone secreted by the adrenal glands that controls the reabsorption of sodium in the nephrons of the kidneys.
order of urine from the collecting duct to the outside of the body
renal pelvis, ureter, urinary bladder, urethra
chemical that inhibits the release of ADH and causes the nephrons of the kidneys to excrete water
a. location of reabsoption of NaCl, water, K+ and HCO
Distal convoluted tubule
b. site of secretion of urea, water, NaCl, K+, creatinine
c. where RBC, WBC, and platelets leave the glomerulus
d. where whole blood enters the glomerulus to be filtered
e. ball of capillaries, site of filtration
f. capsule that surrounds the glomerulus and serves as the first site of the filtrate
g. where whole blood comes into the nephron
i. collect filtered blood to return to circulation
j. site of reabsorption of water and NaCl, part of nephron that extends into the renal medulla
loop of Henle
functional unit of the kidney
part of the hypothalamus that regulates the amount of water in the blood
list of things that are reabsorbed into the blood
water, NaCl, HCO
, K+, glucose
list of things that are secreted into the urine
water, NaCl, creatinine, urea, K+
part of the kidney that includes the glomerulus, Bowman's capsule, and proximal and distal convoluted tubule
part of the kidney that houses the collecting duct and loop of Henle
sequence of filtrate through the nephron
Bowman's capsule --> proximal convoluted tubule --> loop of Henle --> distal convoluted tubule --> collecting duct
sequence of blood through the nephron
renal artery --> afferent arteriole -->efferent arteriole -->peritubular capillaries --> renal
part of urinalysis that test for color and clarity
part of urinalysis that tests for pH, glucose, ketones, specific gravity and proteins
part of urinalysis that tests for RBC, WBC, crystals and bacteria
