A **Questions:** ============== 1\. What is the function of the skin in the human body? 2\. Describe the role of the heart in the circulatory system. 3\. What does the liver do in the digestive system? 4\. Explain the process of digestion that occurs in the stomach. 5\. What is the function of the kidneys in the human body? **Answers:** ------------ 1\. The skin maintains body temperature using sweat and goosebumps. 2\. The heart pumps oxygenated blood around the body and receives de-oxygenated blood back. 3\. The liver makes bile for digestion, filters out toxins, and regulates blood sugar. 4\. The stomach receives food from the oesophagus and begins to break it down with digestive juices (enzymes). 5\. The kidneys filter water and salt out of the blood and create urine. **Questions:** ============== 1\. Discuss the role of the pancreas in the digestive system and its importance for digestion. 2\. Explain how the large intestine contributes to the digestive process. 3\. What is the function of the gall bladder in relation to the liver and digestion? 4\. Describe the process of how oxygen is taken into the body and its journey to the blood. 5\. What are the functions of the brain in the human body, and why are they vital for survival? 6\. What is the role of the oesophagus in the digestive system, and how does it function? 7\. How do the kidneys contribute to homeostasis in the body? 8\. What is the significance of the small intestine in the digestive process? 9\. Describe how the skin helps in thermoregulation and its importance for the body. **Answers:** ------------ 1\. The pancreas produces enzymes necessary for digestion, which help break down food in the small intestine. This is crucial for nutrient absorption, as these enzymes facilitate the chemical processes that convert food into usable energy and nutrients for the body. 2\. The large intestine continues the digestion process by absorbing as much water as possible from the remaining indigestible food matter. It also expels excess fiber and waste, playing a key role in maintaining hydration and eliminating waste from the body. 3\. The gall bladder stores and concentrates bile produced by the liver. Bile is essential for digestion, particularly in the emulsification of fats, making it easier for enzymes to break down fat molecules in the small intestine. 4\. Oxygen is taken in through the lungs, where it is absorbed into the bloodstream. The trachea transports air from the nose and mouth to the lungs, allowing oxygen to reach the blood via the heart, which then pumps oxygenated blood throughout the body. 5\. The brain controls all necessary bodily functions, sends impulses that allow movement, and enables thinking and learning. These functions are vital for survival as they regulate essential processes, coordinate responses to the environment, and facilitate complex behaviors necessary for adaptation and survival. 6\. The oesophagus transports food and drink from the mouth to the stomach. It functions as a muscular tube that uses rhythmic contractions, known as peristalsis, to push the food down into the stomach for further digestion. 7\. The kidneys filter water and salt out of the blood and create urine, which helps regulate the body\'s fluid balance and electrolyte levels. This filtration process is essential for maintaining homeostasis, as it ensures that the body\'s internal environment remains stable despite external changes. 8\. The small intestine digests food using enzymes and absorbs nutrients into the blood. It is significant because it is the primary site for nutrient absorption, allowing the body to utilize the energy and nutrients from food effectively. 9\. The skin maintains body temperature using sweat and goosebumps. When the body overheats, sweat glands produce sweat, which cools the body as it evaporates. Conversely, goosebumps occur when the body is cold, causing hair follicles to contract and trap heat, which is important for maintaining a stable internal temperature.
