During respiration, glucose is converted into carbon dioxide and water in the presence of oxygen within a living cell. The energy is released in the form of ATP or adenosine triphosphate. So, we can say that the energy stored in glucose is transferred into ATP. This process can be shown in the form of a word equation as shown below:

Glucose + oxygen ----> carbon dioxide + water + energy

So, the correct answer is option C.

A digestive system is a group of organs working together to convert complex food into the soluble form of nutrients which are absorbed by the entire body. Food passes through a long tube inside the body known as the alimentary canal. The alimentary canal is made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines with the digestive glands like salivary gland, pancreas, liver and gallbladder which secretes digestive enzyme or juice for breakdown of food.

The kidneys are a pair of bean-shaped organs located in the abdominal cavity. They are involved in the osmoregulation and filtration of blood.

Plaque is a mass of bacteria or a biofilm that grows on the inside surface of the mouth and appears as a white or pale yellow slimy sticky layer and is commonly found between the teeth and near the gums.

The small intestine in adults is a long and narrow tube about 7 meters (23 feet) long. The large intestine is so called because it is wide in diameter. However, it is shorter than the small intestine, only about 1.5 meters (5 feet) long. 

The stomach is a J-shaped, hollow organ located just inferior to the diaphragm in the left part of the abdominal cavity. It is located between the oesophagus and connects with the duodenum. It has two parts fundus and pyloric. 

• One of the major organs of the excretory system is the kidneys. 
• The kidneys are complex organs that play an important role in the production, storage, and release of liquid waste. 
• Gills in fish are part of their excretory system which excretes ammonia. 
• The lungs in the respiratory system excrete some waste products, such as carbon dioxide and water. 
• The skin is another excretory organ that removes the body's wastes through sweat.

Humans and animals are dependent on plants directly or indirectly for food.

William Harvey made the momentous medical discovery that the flow of blood must be continuous and that its flow must be in one direction only. This discovery sealed his place in the history of medicine. William Harvey was born in 1578 in Folkestone, Kent. Harvey studied at Caius College, Cambridge before he enrolled at the University of Padua in 1598. At the time when Harvey was a student at Padua, Galileo was a tutor there and there is little doubt that he was highly influenced by the Galilean way of thinking that enthused the university as a whole. Harvey learned about the human body by dissection and anatomical observation. William Harvey was expired in 1657. Therefore, the correct answer is option C.

• Sweat is excreted through sweat glands. It helps the body to maintain a cool, consistent temperature, which also helps to maintain homeostasis. 
• Sweating is not part of blood circulation, water circulation, and respiration. 
• It helps the body to get rid of the excess of salt and water in the body.

So, the correct answer is option C.
