Question | Answer |
---|---|
Dorsal cavity | cranial cavity and spinal cavity cranial cavity- brain spinal cavity- spinal cord |
Ventral cavity | thoracic cavity R/L pleural cavity- lungs mediastinum- heart, trachea, bronchi, esophagus, thymus gland, aortic arch, thoracic aorta, venae cavae, lymph nodes/nerves, thoracic duct |
Ventral cavity | abdominopelvic cavity abdominal cavity- liver, gallbladder, stomach, pancreas, intestines, spleen, kidneys, ureters pelvic cavity- urinary bladder, female reproductive organs(uterus, uterine tubes, ovaries) male reproductive organs(prostate gland, semin |
homeostasis | -constant state maintained by the body -negative and positive feedback loops |
acids | - increase number of hydrogen ions, decrease number of hydroxide ions -pH less than 7 |
bases | -increase number of hydroxide ions, decrease number of hydrogen ions -pH more than 7 |
(6) protein functions | -provide structure -catalyze chemical reactions -transport substances in blood -communicate information to cells -act as receptors -defend body against harmful agents -provide energy |
simple diffusion | movement of particles trough the phospholipid bilayer from an area of higher concentration to an area of lower concentration (down the concentration gradient) |
osmosis | passive transport of water through a selectively permeable membrane in the presence of at least one impermeant solute |
channel-mediated passive transport (facilitated diffusion) | diffusion of particles through a membrane by means of membrane channels (particles move down their concentration gradient) |
carrier-mediated passive transport (facilitated diffusion) | diffusion of particles through a membrane by means of membrane carriers (particles move down their concentration gradient) |
Four types of tissues | -epithelial -connective -muscle -nervous |
