Highly organised plants have two different types of conducting tissues that function as the transport system. 1) Xylem Phloem. 2. Water and minerals are transported via xylem from the roots to the rest of the plant\’s components. Phloem does the same thing by moving food components from the leaf to other areas of the plant.
Warm-blooded animals like mammals and birds maintain a constant body temperature no matter where they are. Warm-blooded animals must produce more energy to maintain a stable body temperature, and this process requires a lot of oxygen for increased cellular respiration. Therefore, warm-blooded animals must distinguish crucially for warm-blooded animals to distinguish between oxygenated and deoxygenated …
Why is it necessary to separate oxygenated and deoxygenated blood in mammals and birds? Read More »
The essential elements of the human body\’s transport system are the heart, blood, and blood vessels. The roles played by these components HeartBlood with oxygen is circulated throughout the body by the heart. It collects blood that has lost oxygen from various body parts and transfers impure blood to the lungs where it is oxygenated.BloodOxygen, …
(i)An essential part of the body is the lungs. The passage within the lungs separates into successively smaller tubes that ultimately come to an end in balloon-like structures known as alveoli.(ii)The surface provided by the alveoli allows for the exchange of gases. Typically, a dense network of blood arteries can be found inside the alveoli\’s walls. …
Oxygen (O2) and Carbon dioxide(CO2) are transported in humans through the bloodstream. Oxygen is carried to the cells, whereas carbon dioxide is carried away from the cells. The exchange of gases in the alveoli of the lungs and the surrounding blood capillaries. Oxygen is absorbed by the blood capillaries from the lungs’( oxyhaemoglobin ) alveoli …

Glycolysis, a process that breaks down glucose into two 3-carbon molecules termed pyruvate, takes place in the cytoplasm. Various processes in different organisms lead to further breakdown.
Aquatic organisms use oxygen that has been dissolved in water, whereas terrestrial organisms use the oxygen present in the air. In comparison to oxygen in water, the atmosphere has a higher concentration of oxygen. Therefore, although aquatic organisms must breathe more quickly to receive the necessary oxygen, terrestrial organisms do not.
The small intestine has tiny projections called as microvilli that increase the surface area and improve absorption. Numerous blood arteries in the villi take in digested food and transport it to the bloodstream. Each part of our body receives nutrition via the blood.
Complex food molecules are broken into simpler ones by digestive enzymes. This will simplify and improve the process of food absorption. Absorbed food is transported to all parts of the body by the blood.
(i) HCl present in the stomach dissolves food particles and creates an acidic medium. (ii) In an acidic condition , protein-digesting enzymes, pepsinogen, are converted into pepsin. (iii) HCl in the stomach also acts as a protective barrier against many disease-causing pathogens. (iv) Breakdown the wall of the bolus. (v) Food converted into Chyme.
