Know the most important hormonal regulators
of ion reabsorption and secretion and the
function of each hormone:
Angiotensin II- stimulates NaCl in proximal tube and stimulates the adrenal cortex to release Aldosterone- increases Na+ reabsorption & K+ secretion in Distal Convoluted Tubule & Collecting Duct TERM 2
Know the function of the respiratory system
DEFINITION 2 Pulmonary ventilation or breathing Moving air in & out of the lungs TERM 3
External respiration
DEFINITION 3 Gas exchange between alveoli & blood in pulmonary capillaries TERM 4
Internal respiration
DEFINITION 4 Gas exchange between blood in systemic capillaries & tissue cells TERM 5
which parts belong to the upper respiratory
system
DEFINITION 5 o Nose, pharynx & associated structures
which parts belong to the lower respiratory
system
o Trachea, larynx & bronchi & lungs TERM 7
Know the functions of the nose
DEFINITION 7 Filter, Warm, Humidify, Trap dust and infectious agents, Detect olfactory stimuli, and Modify vocal sounds TERM 8
Know the parts of the larynx and the locations
of each part of larynx:
DEFINITION 8 Upper = nasopharynx Middle = oropharynx Between uvula & top of epiglottis lower = laryngopharynx Connects with both esophagus (food tube) & larynx (voice box) TERM 9
Thyroid cartilage:
DEFINITION 9 Forms the anterior wall of the larynx= Adam's apple TERM 10
Epiglottis:
DEFINITION 10 upper leaf-shaped piece During swallowing larynx moves up and epiglottis covers opening to trachea
- increases Na+ reabsorption & K+ secretion
in Distal Convoluted Tubule & Collecting Duct
Aldosterone- TERM 17
stimulates NaCl in proximal tube and
stimulates the adrenal cortex to release
DEFINITION 17 Angiotensin II TERM 18
The volume of water filtered out of the plasma
through glomerular capillary walls into
Bowman's capsules per unit of tim
DEFINITION 18 glomerular filtration rate TERM 19
o Know the functions of the c-shaped
rings:
DEFINITION 19 C-shaped cartilage rings keep lumen open TERM 20
o Lined with non-ciliated cuboidal
epithelium
DEFINITION 20 Bronchioles:
2 or more alveoli that share a common
opening to the alveolar duct
o alveolar sacs: TERM 22
what does the urinary system consist of :
DEFINITION 22 2 kidneys & 2 ureters, 1 urinary bladder & 1 urethra TERM 23
Know the functions of the kidneys:
DEFINITION 23 Regulation of Plasma ion composition Regulation of Body water Volume (BP) Regulation of blood pH (with lung) Production of Hormones Excretion of waste TERM 24
o Know the 2 parts of the
kidney
DEFINITION 24 Cortex outer portion Medulla- inner portion TERM 25
o Know what the Bowmans capsule is part of
DEFINITION 25 o Glomerular (Bowmans) capsule surrounds the glomerular capillaries
Know the parts of the renal tubule:
- Proximal convoluted tubule (cortex) 2. Descending Loop of Henle (into medulla) ascending Loop of Henle (into medulla)
- Distal convoluted tubule (cortex) Drains into the Collecting duct minor calyx TERM 32
o Know the cells of the inner wall of the
glomerulus:
DEFINITION 32 o The cells that make up the inner wall of the glomerular capsule called Podocytes support capillary epithelium TERM 33
Remove substances, such as wastes, drugs,
and excess ions, from blood in the peritubular
capillaries and transport them into the
DEFINITION 33 Tubular Secretion: TERM 34
Reabsorb needed compounds & return about
99% of filtered water
DEFINITION 34 Tubular reabsorption: TERM 35
Know what glomerular filtration rate is
DEFINITION 35 The volume of water filtered out of the plasma through glomerular capillary walls into Bowman's capsules per unit of time.
