HNF 150: Body Basics and Digestion
Chewing ✔️✔️MD; crush and grind food with teeth
Peristalsis ✔️✔️one way, rhythmic, longitudinal muscles that moves the food in its many stages
through the digestive tract
Here’s another batch of questions and answers for HNF 150:
How does the body regulate blood sugar levels?
The body uses insulin and glucagon to regulate blood sugar levels. Insulin lowers blood sugar by
promoting glucose uptake into cells, while glucagon raises blood sugar by releasing stored glucose from
the liver. ✔️✔️
What is the role of water in thermoregulation?
Water helps regulate body temperature by absorbing heat, transporting it to the skin’s surface, and
allowing for heat loss through sweating and evaporation. ✔️✔️
Why are nuts considered a good source of healthy fats?
Nuts contain monounsaturated and polyunsaturated fats, which help reduce bad cholesterol levels,
improve heart health, and provide essential fatty acids. ✔️✔️
What is the relationship between calcium and vitamin D?
Vitamin D helps the body absorb calcium from food, which is crucial for maintaining strong bones and
preventing bone-related diseases. ✔️✔️
How does alcohol affect nutrient absorption?
Alcohol can impair nutrient absorption by disrupting the digestive system, reducing the efficiency of
nutrient breakdown and absorption in the intestines. ✔️✔️
, What is the importance of zinc in the immune system?
Zinc supports the immune system by promoting the development and function of immune cells, and it
also plays a role in wound healing. ✔️✔️
Why is it important to consume antioxidants from various food sources?
Different antioxidants provide unique benefits, and consuming a variety helps protect cells from
oxidative damage, reducing the risk of chronic diseases. ✔️✔️
How do trans fats affect cardiovascular health?
Trans fats raise LDL (bad) cholesterol levels and lower HDL (good) cholesterol levels, increasing the risk
of heart disease and stroke. ✔️✔️
What is the role of the liver in detoxification?
The liver processes toxins and harmful substances, breaking them down into less harmful compounds
that are excreted through urine or bile. ✔️✔️
What is the effect of high-fiber diets on cholesterol levels?
High-fiber diets can help reduce cholesterol levels by binding to cholesterol in the digestive tract and
removing it from the body. ✔️✔️
How does the body use protein for muscle repair?
After exercise, protein helps repair and rebuild muscle fibers that are broken down, promoting muscle
growth and recovery. ✔️✔️
What are the benefits of eating a variety of colorful fruits and vegetables?
Colorful fruits and vegetables contain a range of vitamins, minerals, and antioxidants, which help reduce
inflammation, improve immune function, and protect against chronic diseases. ✔️✔️
How do saturated fats impact heart health?
Saturated fats raise LDL cholesterol levels, which can lead to plaque buildup in arteries and increase the
risk of heart disease. ✔️✔️
