The transport system is mainly comprised of following organs:
Heart: Heart is a pumping organ and pumps blood. As blood carries gases and food and waste product along with it so heart plays a major role in transportation.
Lungs: The main job of lungs is in facilitating transport of oxygen and carbon dioxide to and from the body respectively.
Liver: Food goes to liver after it is absorbed by small intestine. From liver the food is distributed to different parts of body. This system is also called as hepatic portal system.
The bronchioles in lungs are finely branched and end up in air sacs. The structure of air sac increases the surface area inside lungs. This helps in making a larger area for exchange of gases.

Oxygen and carbon dioxide are transported in human beings with a dedicated gas transportation system. This system is mainly composed of following parts: Lungs: Lungs help in breathing in oxygen rich air and breathing out carbon dioxide rich air.

Oxygen and carbon dioxide are transported in human beings with a dedicated gas transportation system. This system is mainly composed of following parts:
Lungs: Lungs help in breathing in oxygen rich air and breathing out carbon dioxide rich air.
Heart: Heart pumps deoxygenated blood to lungs for oxygenation and pumps oxygenated blood to different organs of body.
Veins: Veins usually carry deoxygenated blood from different body parts to the heart. One exception is the pulmonary vein which carries oxygenated blood from lungs to heart.
Arteries: Arteries usually carry oxygenated blood from heart to different parts of the body. One exception is pulmonary artery which carries deoxygenated blood from heart to lungs.
There are two types of respiration for oxidization of glucose. (a) Aerobic respiration: This involves complete oxidation of glucose hence optimum output of energy is achieved. This happens in presence of oxygen. (b) Anaerobic respiration: As the name suggests this happens in the absence of oxygen heRead more
There are two types of respiration for oxidization of glucose.
(a) Aerobic respiration: This involves complete oxidation of glucose hence optimum output of energy is achieved. This happens in presence of oxygen.
(b) Anaerobic respiration: As the name suggests this happens in the absence of oxygen hence complete oxidation of glucose does not take place. Usually bacteria show anaerobic respiration. Even sometimes in our calf muscles anaerobic respiration takes place.
In the aquatic habitat the concentration of oxygen is good up to a certain depth only. Moreover, as oxygen is available as dissolved in water, so taking oxygen from there is not a very efficient method to that. In terrestrial habitat oxygen is available in free form so it is easier to absorb by orgaRead more

In terrestrial habitat oxygen is available in free form so it is easier to absorb by organisms. This is more efficient so terrestrial organisms can facilitate better utilization of food by way of respiration.
In the small intestine the innermost layer is in the shape of finger like structures. These are known as villi. Several folds because of villi increase the absorbing surface of small intestine. The blood capillaries in villi absorb simpler molecules from food.

The function of digestive enzyme is to hasten the process of breaking up of complex molecules into simpler and absorbable molecules. This makes it easy for the body to absorb food.

How are the lungs designed in human beings to maximise the area for exchange of gases?
The bronchioles in lungs are finely branched and end up in air sacs. The structure of air sac increases the surface area inside lungs. This helps in making a larger area for exchange of gases.
