Answer 1

Answer 7

• The heart has four chambers: two atria and two ventricles.
• Our heart has four separate chambers that pump blood, two on the right side and two on the left.
• The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
• The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.The right ventricle pumps the oxygen-poor blood to the lungs.
• The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.The right ventricle pumps the oxygen-poor blood to the lungs.The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
• The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.The right ventricle pumps the oxygen-poor blood to the lungs.The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.The left ventricle pumps the oxygen-rich blood to the body.

Answer 8

• Their function is to increase the surface area of the small intestinal wall for absorption of the digested food.
• These projections absorb the protein molecules and help in the transfer of the proteins to all cells and tissues.
• The inside of the small intestine is lined with villi that absorb nutrients from the liquid mixture called chyme produced in the stomach from the food we eat.
• The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions.

Answer 9

• Anaemic is a condition in which there is a deficiency of red cells or of haemoglobin in the blood, resulting in pallor and weariness.
• It is a condition in which the blood doesn't have enough healthy red blood cells.
• Anaemia results from a lack of red blood cells or dysfunctional red blood cells in the body.
• This leads to reduced oxygen flow to the body's organs.
• Anaemia can have many causes, including: dietary deficiency – lack of iron, vitamin B12 or folic acid in the diet. malabsorption – where the body is not able to properly absorb or use the nutrients in the diet, caused by conditions such as coeliac disease. inherited disorders – such as thalassaemia or sickle cell.

Answer 10

• Tidal volume is the amount of air that moves in or out of the lungs with each respiratory cycle.
• It measures around 500 mL in an average healthy adult male and approximately 400 mL in a healthy female.
• It is a vital clinical parameter that allows for proper ventilation to take place.
• Tidal volume is the amount of air breathed in with each normal breath

Answer 11

• Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes.
• In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
• Fermentation is the process in which a substance breaks down into a simpler substance.
• Microorganisms like yeast and bacteria usually play a role in the fermentation process, creating beer, wine, bread, kimchi, yogurt and other foods.
• Fermentation, chemical process by which molecules such as glucose are broken down anaerobically.
• More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old.

• Fermentation is the process by which a batter is made soft and puffy.
