An equation must be balanced in order to comply with the " Law of Conservation of Matter " which says that matter is neither created nor destroyed in the course of a Chemical Reaction. An unbalanced equation would imply that atoms have been created or destroyed.

Bile does not contain any enzyme but it is essendal for digestion because bile is alkaline and contain salts which helps to emulsify the fat present in the food. So, the bile perform two functions:
- The food coming from the stomach is acidic and has to be made alkaline for the pancreatic enzymes to act.
- The bile salts breakdown the fat present in the food into smaller globules. This increases the efficiency of enzymes in the small intestine to digest the food effectively.

The major role of the stomach in digestion is to churn the food properly coming from the esophagus so that small intestine can absorb the molecules. In the stomach, food and water are mixed properly to form a slurry known as chyme. After this process, the food is ready to move into the small intestine. The liver, gall bladder, and pancreas are known as the alimentary system of humans and together help in the process of digestion.

The main components of the transport system in human beings are the heart, blood, and blood vessels.
a. Heart pumps oxygenated blood throughout the body. It receives deoxygenated blood from the various body parts and sends this impure blood to the lungs for oxygenation.
b. Blood helps in the transport of oxygen, nutrients, CO2, and nitrogenous wastes.
c. The blood vessels (arteries, veins, and capillaries) carry blood either away from the heart to various organs or from various organs back to the heart.

Breathing by mouth is harmful in the sense that the air which is taken in is not filtered , it is taken in with its impurities . Hence it is said that we should not breathe by mouth and always breathe via our nose. The nasal way of breathing is the best way because our nose contains nasal hair which are tiny hair inside the nose which filter the air and make it purified and hence safer .

Three Characteristics Of Lungs Which Make Them An Efficient Respiratory Surface Are:
1. They Have A Rich Blood Supply.
2. Their Inner Surface Is Moist.
3. They Have Large Combined Surface Area.

Large animals have advanced respiratory system that allows them to take in oxygen and give out carbon dioxide.
Lungs are usually present in such animals where the exchange of gases takes place.
Blood carries oxygen from the lungs to every cell of the body and then takes carbon dioxide from cells back to lungs.
The arrangement in the bodies of large animals to meet oxygen requirement is a respiratory pigment in the blood called hemoglobin.

| Aerobic Respiration | Anaerobic Respiration |
| Oxygen is present when this form of respiration takes place. | Oxygen is absent when this form of respiration takes place. |
| Gases are exchanged in this form of respiration. | Gases are not exchanged in this form of respiration. |
| It can be found in the cytoplasm and the mitochondria. | It can be found only in the cytoplasm. |
| Glucose breaks down into carbon dioxide and water. | Glucose breaks down into ethyl alcohol, carbon dioxide, and energy |
| All higher organisms such as mammals have this type of respiration. | Lower organisms such as bacteria and yeast use this type. In other organisms, it occurs during heavy activities |

Breathing cycle is rhythmic because it is a regular process of inspiration and expiration in an oscillating cycle. Neuronal impulses are responsible for this control which transmits between the respiratory centers in the brain and the muscles involved in inspiration in the chest and diaphragm.
Gaseous exchange is a continuous process because it involves the process of diffusion. Diffusion of gas takes place from the region of high concentration to a region of low concentration which normally involves exchange of oxygen and carbon dioxide during the process of respiration in living organism and its environment.

The "walls of trachea" are supported by "rings" to restrict it from "collapsing". "Trachea" is also referred as "windpipe" as it provides a "passage for air" and carries it to the lungs. In humans, this is a part of the "respiration" process. The "air" enters the hair and mucus lined nostril. It then passes through the trachea and enters the lungs. "Trachea" bifurcates into "bronchi" which further divides into alveoli where exchanges of gases takes place.

Alveoli are covered with blood capillaries so that the exchange of gases can take place between the membranes of the alveoli and the surrounding capillaries. The blood capillaries covering alveoli have a low oxygen and high carbon dioxide concentrations. This allows oxygen to diffuse into the blood and carbon dioxide to diffuse out of the blood.

The glottis is guarded by epiglottis because it prevents the entry of food in wind pipe. If the food enters wind pipe, then it chokes it, leading to the death of the person.
