The volume of air inspired or expired during normal breathing is called:
A. Total lung capacity
B. Residual volume
C. Vital capacity
D. Tidal volume
Answer: Option D
Solution (By JKExamLibrary)
Tidal volume (TV) is the amount of air breathed in or out in one normal respiratory cycle, about 500 mL in a healthy adult. Vital capacity is the maximum air exhaled after a maximum inspiration. Total lung capacity is the total volume of air lungs can hold. Residual volume is the air remaining in lungs after maximum expiration to prevent alveolar collapse.
Explanation:
The holotype is the single physical specimen designated by the original author when the species is first formally described. It serves as the ultimate reference point for that species name. An isotype is a duplicate of the holotype, syntypes are multiple specimens cited when no holotype was designated, and paratypes are additional specimens cited in the original description.
Explanation:
A sphygmomanometer, often used with a stethoscope, measures arterial blood pressure (systolic/diastolic) in mmHg. A stethoscope listens to heart/lung sounds, thermometer measures temperature, ECG records heart electrical activity. Normal blood pressure is about 120/80 mmHg.
Explanation:
Adventitious roots arise from non-root tissues like stems, leaves, or branches. Examples: prop roots of banyan, stilt roots of maize, aerial roots of orchids. Taproot and fibrous roots develop from the radicle.
