Why is the total area of its faces calles the surface area of the cube?
That is the definition of the surface area!
Total surface area of two identical cubes?
(surface area of cube 1 or 2 (either)) times 2 = (total surface area of two identical cubes)
What is the total curved surface area of a hollow hemisphere?
total curved surface area = 2*pie*r^2
What is the effect of dividing a big particle into smaller ones on the total exposed surface area?
The total surface area increases.
What is the surfqace area of a cylinder?
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
Why is the velocity of blood flow the lowest in capillaries?
the total surface area of the capillaries is larger than the total surface area of the arterioles
What organ does oxygen pass from into the capillaries?
I believe its the alveoli in the lungs. These alveoli provide a large surface area for gaseous exchange.
How does microvilli help in the digestion of food?
The provide the small intestine with a large surface area, and provides the capillaries close to the surface.
What is the surface area is the sum of the areas of all the surfaces of a three dimensional object called?
The total surface area! The total surface area! The total surface area! The total surface area!
Which vessels in the human body have the biggest surface area?
Capillaries
Why must capillaries have a greater surface area to volume ratio compared to arteries?
Capillaries are tiny blood vessels. They need to have a greater surface area to volume ratio because they need to diffuse oxygen quicker.
Why is the small size of the capillaries surrounding the alveoli important physiologically?
The size of the capillary is smaller than the red blood cells. The exact reason for this is not known. The red blood cells get folded when they pass through the capillaries. This phenomena buy time for the blood to flow through the capillaries, probably. Secondly it will create larger surface area of total number of capillaries to flow the same amount of blood. You have better exchange of gases through larger surface area.
What provide the greatest surface area for gas exchange?
Alveoli in the lungs provide the greatest surface area for gas exchange in the body. They are tiny air sacs that are surrounded by capillaries where oxygen and carbon dioxide are exchanged during respiration. The numerous alveoli increase the total surface area available for this gas exchange process.
What role do the capillaries play in gaseous exchange?
Capillaries are very thin and form almost web like structures. Because of how thin they are, they have a favorable surface area to volume ratio. Capillaries increase the surface area available for gas to diffuse into the blood. More suface area leads to more gas exchange.
Why alveoli in the lungs have large surface area and many blood capillaries surrounding the?
The alveoli provide large surface area for the exchange of gases between the blood and the air. Each alvoeli is surrounded by many capillaries(tiny blood vessels). The very thin walls and large surface area of the alveoli and numerous capillaries surrounding them enable gases to be exchanged quickly and efficiently. Oxygen in the inhaled air diffuses from the alveoli to the blood in the capillaries. The blook then carries the oxygen to the cells in the other parts of the body. The waste product of respiration, CO2 , diffuses from the blood to the lungs through the capillaries surrounding alveoli. It leaves the body through bronchi and trachea when you exhale( breathe out).
What is the total area of all surface of an object called?
It is called "the total surface area".
Why is capillaries branched out?
The capillaries are branched out to increase surface area for diffusion of substances like nutrients, hormones, and waste products like carbon dioxide.
