Answer 1

Answer:

1. Respiration, Digestion
2. Saliva acts in relation to taste, mastication , bolus formation, enzymatic digestion and swallowing.
3. The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.
4. Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.
5. The core function of the human stomach is as an aid to diges- tion. The four key components of gastric digestive function are its function as a reservoir, acid secretion, enzyme secre- tion and its role in gastrointestinal motility.
6. Anaerobic respiration (both glycolysis and fermentation) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the mitochondria.
7. a substance, usually produced by plants and animals, which helps a chemical change to happen more quickly, without being changed itself.
8. Villi are small finger-like projections located in the walls of the small intestine. Their function is to increase the surface area in order to maximise the absorption of digested food. Villi numbers vary between 10 to 40 per square metre of tissue and are typically 0.5 to 1 mm long.
9. ATP ( Adenosine triphosphate)
10. Yeast and bacteria
11. The other name of extracellular fluid is 'filler substance'. Extracellular fluid represents all the body fluid which is present outside the cells. It mediates the exchange of substances between the cell and its exterior.
12. Phloem
13. Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
14. The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.
15. Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs.
16. End products of respiration are carbon dioxide, water and energy in the form of ATP.
17. Anaerobic respiration is a process in which energy is released from glucose without requiring oxygen. It takes place in the cytoplasm. It coverts glucose into ethanol and carbon dioxide. It is less efficient than aerobic respiration as it releases less energy than the energy released in aerobic respiration.
