The volume of air moved in and out of the lung during quiet breathing is called _________.
A. Tidal volume
B. Vital capacity
C. Ventilation rate
D. Total lung capacity
Which of the following is correct regarding the renin‐angiotensinogen mechanism?
A. A decrease in blood pressure results in the release of renin which converts angiotensinogen I to angiotensinogen II. The angiotensin‐converting enzyme converts angiotensinogen II to angiotensin, which stimulates the adrenal cortex to secrete aldosterone, a hormone that is involved in increasing blood pressure.
B. A decrease in blood pressure results in the release of renin which converts angiotensinogen to angiotensin I. The angiotensin‐converting enzyme converts angiotensin I to angiotensin II, which stimulates the adrenal cortex to secrete aldosterone, a hormone that is involved in increasing blood pressure.
C. A decrease in blood pressure results in the release of angiotensin‐converting enzyme, which converts angiotensin to angiotensinogen I. The angiotensin‐converting enzyme then converts angiotensinogen I to angiotensinogen II. Angiotensinogen II then stimulates the adrenal cortex to secrete renin, which is involved in increasing blood pressure.
How is cardiac output calculated?
A. Heart rate x mean artieral pressure
B. Stroke volume / heart rate
C. Stroke volume x Heart rate
D. Stroke volume x Total peripheral resistance
This is not a function of insulin

A. Both are equal
A. Excessive urine formation

Why do emotions such as anger or fear slow digestion?
