Explanation:
Human heart:-
see labelled diagram of human heart in attachment.
Answer 1. - The heart:- The heart is a muscular organ having different chambers to prevent the oxygen rich blood from mixing with the blood containing Carbondioxide. Auricles receive the blood through veins while the ventricles pump the blood through arteries. Aorta is the main artery while vena cava is the main vein. Right auricle receives the impure (deoxygenated) blood and pumps into rright ventricle which further pumps to lungs for oxygenation. The oxygenated blood from lungs is brought by pulmonary veins into left auricle which pumps it into the entire body through main artery( Aorta).
The pulmonary vein is the only vein that brings oxygenated blood from lungs into the left auricle.
The pulmonary artery is the only artery which carries deoxygenated blood into the lungs for oxygenation.
The separation of oxygenated blood from deoxygenated blood allows a highly efficient supply of oxygen to the body.

Answer 2. - ( see labelled diagram of respiration in human beings the attachment)
In human beings , air is taken through the nostrils. The entire nasal passage is lined with fine hairs and mucus which helps in the filtration of air. From nostrils, the air passes through the throat and ultimately into the lungs. Rings of cartilage are present in the throat which ensure that the air passage does not collapse.
Within the lungs, the bronchi divides into bronchioles and bronchioles finally terminate in balloon like structures called alveoli which provide a larger surface where the exchange of gases can take place.
During breathing, Inhalation get raised , diaphragm larger, chest cavity larges, alveoli expanded.
During breathing, Exhalation air is taken out ,lungs always contain a residual volume of air so that Carbondioxide is released.

Respiration in plants:-
The mechanism by which organisms obtain oxygen from the environment and release
carbon dioxide, is termed breathing. Respiration is a much more complex process.
It includes:-
- breathing, which involves the mechanism of exchange of gases, Oxygen and carbon dioxiele, and
- oxidation of digested food occurring in the cells in order to release energy. The energy released during Respiration in plants is utilized for carrying out biological functions essential for survival and maintenance of an plants.
