The most important osmoreceptors are located in the | hypothalamus |
The activity of the thrist center will be increased if | blood osmolarity is increased |
The most abundant anion in plasma membranes is | phosphate |
Blood calcium levels are increased by | parathyroid hormone |
A decrease in the rate and depth of breathing could theoretically alleviate | metabolic alkalosis |
Symptoms of high plasma pH may include | muscle twitches |
Addison disease is a disorder of the | adrenal cortex |
The largest volume of water is excreted by the | urinary system |
The term retroperitoneal means | behind the peritoneum |
The outer portion of the kidney is called the | renal cortex |
Which of the following best represents the path of a blood cell as it passes through the kidney? | glomerus, afferent arteriole, pertibular capillaries, renal vein |
Which of the following structures is found in the renal medulla? | pertibular capillaries |
The part of the nephron that drains in the nephron loop is the | proximal convoluted tubule |
The juxtaglomerular apparatus consists of cells in the | distal convoluted tubule; afferent arteriole |
An active process that moves substances from the blood into the nephron is | tubular secretion |
Substances are reabsorbed from the distal convoluted tubule into the | peritubular capillaries |
Antidiuretic hormone increases | water reabsorption in the collecting duct |

The head of the spermatozoon contains large amounts of | DNA |
An acrosome would be found in a | spermatozoon |
The uterine proliferative phase occurs during | follicular phase |
High levels of progesterone result in | decreased levels of leutinizing hormones |
Increased activity of the interstitial cells results in | decreased leutinizing hormone secretion |
Based on your knowledge of word parts, mastitis is | inflammation of the breast |

The units of hereditary are called | genes |
Chromosomes contain | genes, DNA, alleles |
A recessive gene | only alters the phenotype in homozygous individuals |
An individual that is heterozygous for a completely dominant trait | will show the dominant phenotype |
An example of genotype is | heterozygous alleles |
Eye color is determined by three pairs of genes. Its mode of inheritance is best described as | multi-factorial |
The ability of a particular gene to determine phenotype can be altered by | other genes, gender, environmental factors |
What is true of multifactorial traits? | they're detremined by one or more gene pair |
A chemical that causes a chromosome to break is called a(n) | mutagen |
Duchenne muscular dystrophy results from a defect in the dystrophin gene and is detectable at birth. This disorder is best described as | congenital, hereditary, genetic |
