Answer (1)
This question focuses on key terms related to the digestive system, a crucial topic in Biology. Let's break down each part:
Digestion process (8 letters) : The process described here involves breaking down food into simpler substances through enzymatic reactions. This process is known as Digestion . It begins in the mouth and involves various organs, such as the stomach and intestines, where enzymes play a key role in chemically breaking down food into nutrients that the body can absorb and use.
Semi-fluid mass (5 letters) : The semi-fluid mass of partially digested food combined with gastric juices is called Chyme . After food is ingested and initially processed in the stomach, it is mixed with acidic digestive juices, turning it into chyme. This mixture then slowly passes into the small intestine, where further digestion and nutrient absorption occur.
Enzyme breaking down proteins (8 letters) : An important enzyme that breaks down proteins into amino acids is Protease . Proteases are essential because proteins are large, complex molecules that need to be broken down into smaller components, like amino acids, for the body to utilize them effectively.
Muscle contractions in digestion (11 letters) : The involuntary muscle contractions that move food through the digestive tract are known as Peristalsis . This process involves a series of wave-like muscle contractions, which occur in the esophagus, stomach, and intestines, propelling the food and liquid forward, ensuring continuous movement and digestion.
