Question
1.. Calculate the inspiratory capacity, vital capacity, and total lung capacity for a patient with the following respiratory volumes.
i. Tidal volume = 450ml
ii. Expiratory Reserve Volume = 1,100ml
iii. Inspiratory Reserve Volume =3,000ml
iv. Residual Volume=1,200ml
Inspiratory Capacity = ?
Vital Capacity=?
Total Lung Capacity=?
2.) Fill in the blanks ; Hyperventilation the amount of carbon dioxide exhaled and therefore the blood ph. Hypoventilation the amount of carbon dioxide exhaled and therefore to the blood Ph.
3. ) List the target tissue and effects of each of the following hormones :
i. Insulin
ii. Adrenocorticotropic Hormone :
iii. Growth Hormone
iv. Prolactin
v. Oxytocin
vi. Thymosin
4.) Explain why an increase in thyroid hormone generally leads to a decrease in thyroid - stimulating hormone
Explanation / Answer
Answer1
I) Inspiratory capacity=tidal volume + Inspiratory reserve volume = 3450 ml for above case
2) vital capacity=tidal volume + Inspiratory reserve volume+expiratory reserve volume=4550 ml in above case
3) Total lung capacity= tidal volume + Inspiratory reserve volume+expiratory reserve volume+ residual volume=5750 ml
Answer2
Hyperventilation INCREASES amount of Co2 and hence blood pH (alkalosis)
Hypoventilation DECREASES amount of Co2 and hence blood pH(acidosis)
Answer3
Insulin: Regulates GLUCOSE LEVEL/STORAGE in LIVER
Adrenocorticotropic hormone: stimulate CORTISOL RELEASE from anterior PITUTARY GLAND
GH: stimulate LIVER to release IGH for BONE GROETH. ALSO REDUCES FAT and promote PROTEIN SYNTHESIS
Prolactin: Enables mammary gland to produce millk
Oxytocin: stimulate UTERINE Muscles by increasing PG so labor begins
Thymosin: trigger T CELL production which boost IMMUNE SYSTEM
Answer4
TSH stimulate thyroid hormone production and hence increase in its level would automatically trigger inhibitory signal as normal regulatory mechanism of the body.
