Properties of Hormones/Respiratory System Flashcards
Antidivretic hormone (ADH)
Posterior Pituitary= organ that secretes ADH
Stimulus for secretion= blood concentration increases
Target tissue= collecting kidneys & papillary
Oxytocin
Posterior Pituitary= organ that secretes
Stimulus for secretion= fetus, suckling of the nip by infant
Target tissue= milk ducts in uterus
Thyroid-Stimulating Hormone (TSH)
Anterior Pituitary= organ that secrets
Stimulus for secretion= Thyrotropin releasing hormone
Target tissue= thyroid
Adrenocorticotrophic hormone (ACTH)
Anterior Pituitary= organ that secretes
Stimulus for secretion= corticotrophin (CRH)
Target tissue= adrenal cortex
Growth Hormone
Anterior Pituitary= organ that secrets
Stimulus for secretion= Growth hormone releasing hormone
Target tissue= nearly all cells
Prolactin
Anterior Pituitary= organ that secretes
Stimulus of secretion= prolactin releasing hormone
Target Tissue= mammary gland
Melatonin
Pineal Gland= organ that secretes
Stimulus for secretion= decreased ambian light
Target Tissue= reticular stimulation in brain system
Thyroxin & Triiodothronine (T4&T3)
Thyroid gland= organ that secretes
Stimulus for secretion= TSH
Target Tissue= all body cells
Calcitonin
Thyroid gland= organ that secretes
Stimulus for secretion= calcium levels in blood rise
Target tissue= bones
Thymosin & Thymopoietin
Thymus= organ that secretes
Stimulus for secretion= development of thympocytes (immature)
Target Tissue= T lymphocyes in thymus
Parathyroid hormone
Parathyroid gland= organ that secretes
Stimulus for secretion= decreased calcium in blood
Target tissue= bone, kidney, small intestine
Cortisol
Adrenal Cortex= organ that secrets
stimulus for secretion= directly by ACTH
Target tissue= most body cells mainly liver, muscle, and adipose
Aldosterone
Adrenal Cortex= organ that secrets
stimulus for secretion= ACTH, increased K+, & hydrogen ions in blood
Target tissue= all body cells
Epinephrine & Norepinephrine
Adrenal Cortex= organ that secretes
Stimulus for secretion= sympathetic nervous system
Target tissue= all body cells
Insulin
Pancreas= organ that secretes
Stimulus for secretion= increase glucose in blood
Target tissue= all body cells
Glucagon
Pancreas= organ that secretes
Stimulus for secretion= decrease in concentrations of glucose in the blood
Target Tissue= Liver, adipose, muscle cells
Equal to the TV, ERV, IRV, RV
Total lung Capacity
volume of air remaining in the lungs after forceful expiration
Residual volume (RV)
Volume of air forcibly inspired after a tidal inspiration
Inspiratory reserve volume (IRV)
Equal to the TV, IRV, and ERV
Vital capacity
volume of air exchanged with normal, quiet breathing
Tidal Volume (TV)
Equal to the TV & IRV
Inspiratory capacity
Volume of air forcibly expired after a tidal expiration
expiratory reserve volume (ERV)
oxygen enters & carbon dioxide exits
gas exchange
altered by changing blood carbon dioxide levels
regulation of blood pH
movement of air past vocal folds makes sound and speech
Voice production
Smell occurs when airborne molecules are drawn into the nasal cavity
olfaction
against microorganisms by preventing entry & removing them
Protection
The nervous system works through secretions of _____________ whereas the endocrine system works via secretions of ___________.
Neurotransmitters
hormones
Name a set of hormones that are antagonist.
Calcitonin & parathyroid hormone
According to Boyle’s Law, as the volume of the container increases, the pressure _______, and as the volume of the container decreases, the pressure _______.
decreases
increases
Passive expiration is achieved primarily by the….
elastic recoil of the lungs
Hyperventilation increases the amount of carbon dioxide exhaled & therefore ________ the blood pH.
increases
Hypoventilation decreases the amount of carbon dioxide exhaled & therefore ________ the blood pH.
decreases
