Answer:
The correct answer is option B- pressure within the alveoli.
Explanation:
Intrapulmonary pressure is the pressure within the lungs especially in the alveoli of the lungs so is also known as "intra-alveolar pressure".
This pressure helps in the breathing process as :
1. During inspiration - The thoracic cavity volume increases due to which the intra-pulmonary pressure becomes less than the atmospheric pressure which causes the lungs to inhale about 500 ml of air.
2. During expiration- the thoracic volume decreases which cause the intra-pulmonary pressure larger than atmospheric pressure which causes the lungs to exhale the air.
Thus, option B- pressure within the alveoli is the correct answer.
Answer: b) Apical surface
Explanation:
The epithelium is characterized by the juxtaposition of cells and the little extracellular matrix. The region of the cell facing the free surface is the apical pole, while the opposite side is the basal pole. The apical domain is always turned to the outer surface from a closed cavity or tube. The stomach is a dilated portion of the digestive tract where the food cake is macerated and partially digested in a paste, the chimo (from Greek chymos, juice). In adults, holds 1.5L and, when extended, 3L.Given that food enters the stomach and interects with the region facing the surface, food would be in contact with the Apical surface.
Veins are favored over arteries because they have thinner walls, and thus they are easier to pierce. There is also lower blood pressure in veins so that bleeding can be stopped more quickly and easily than with arterial puncture.
Answer:
The correct answer is A. The cell membrane is both hydrophilic and hydrophobic due to the presence of phospholipid.
Explanation:
98% of the lipids present in cell membranes are amphipathic, that is, they have a hydrophilic end (which has affinity and interacts with water) and a hydrophobic end (which repels water). The three main types of lipids in eukaryotic membranes are phospholipids, sphingoglucolipids and steroids (especially cholesterol); It is worth mentioning that phosphoglycerides and sphingolipids are found in all cells. The latter, glycolipids and steroids, do not exist or are scarce in the plasma membranes of prokaryotic cells, fungi and some protists. There are also neutral fats, which are non-amphipathic lipids, but only represent 2% of the total membrane lipids.
