Answer:
Amount of air inhaled or exhaled per breathing stroke is called as tidal volume. Tidal volume is 400 ml for women while for men it is 500 ml.
Explanation:
In respiration, tidal volume is defined as the volume of air that a person inhales or exhales in one stroke of normal breathing.
The tidal volume varies in adult men and women. In resting condition, tidal volume is 400 ml for women while for men it is 500 ml.
This tidal volume varies with the requirement of the body. During intense physical exercise the amount of gas intake increases in order to full fill the requirement of body and hence the tidal volume increases.
For a male, 3.72 inches.
for female, about 3 inches
it also depends on which finger, the measurements I gave you are of a average person's middle finger.
Answer:
Option B
The plicae circulares, villi, and microvilli
Explanation:
The plicae circulares are the folds of mucous membrane on the inside of the small intestine. They are covered with tiny hair-like structures called the villi, and microvilli. The purpose of those folds is to increase the surface area for the absorption of food nutrients to take place in the small intestine before the food finally moves on to the large intestine for excretion.
The tiny hair-like projections (villi, and microvilli) further increase the surface area available for nutrient absorption by providing extra surfaces in which the nutrients can diffuse into the small intestine through.
This makes option B correct.
Answer:
A
If the level of thyroxine in the blood is high then the pituitary gland releases less TSH. Therefore, a low level of TSH means that your thyroid gland is overactive and is making too much thyroxine. Thyroxine (T4). A high level of T4 confirms hyperthyroidism
