BJC Health Science Body Systems (Digest./Circulat./Musculoskel.)

What are the primary digestive enzymes and their functions?

• The primary digestive enzymes are amylase, protease, and lipase. Their functions are to break down carbohydrates, proteins, and fats, respectively.

• The primary digestive enzymes are oxygen, nitrogen, and carbon dioxide. Their functions are to facilitate respiration and gas exchange.

• The primary digestive enzymes are cellulose, pectin, and lignin. Their functions are to provide structure and support to plant cell walls.

• The primary digestive enzymes are caffeine, sugar, and salt. Their functions are to provide energy and enhance flavor.

Describe the pathway of blood circulation in the human body.

• The oxygenated blood returns to the right atrium from the lungs

• The blood circulation pathway begins with the blood going from the left ventricle to the lungs for oxygenation

• The pathway of blood circulation starts with the left atrium receiving deoxygenated blood from the body

• The pathway of blood circulation in the human body starts with the right atrium receiving deoxygenated blood from the body, then it goes to the right ventricle and is pumped to the lungs for oxygenation. From the lungs, the oxygenated blood returns to the left atrium, then to the left ventricle, and is pumped out to the rest of the body.

What is peristalsis and how does it contribute to the digestive system?

• Peristalsis is the name of the enzyme that helps digest proteins

• Peristalsis is the process of breaking down food in the stomach

• Peristalsis is the term for the absorption of nutrients in the small intestine

• Peristalsis helps move food through the digestive system by contracting and relaxing the muscles of the digestive tract.

Discuss the structure of bones and their role in the musculoskeletal system.

• Bones are made of cartilage and have no role in the musculoskeletal system

• Bones are not involved in providing support or protection for the body

• Bones are only responsible for producing blood cells and have no other function

• Bones provide structure, support, and protection for the body, as well as serving as a storage site for minerals and producing blood cells.

Explain the anatomy of the heart and its functions in the circulatory system.

• The heart has three chambers and its main function is to produce hormones

• The anatomy of the heart includes five chambers and its function is to digest food

• The heart is a single-chambered organ and its function is to regulate body temperature

• The anatomy of the heart includes four chambers - two atria and two ventricles, along with valves and blood vessels. Its functions in the circulatory system include pumping oxygenated blood to the body and deoxygenated blood to the lungs for oxygenation.

What are the organs involved in the digestive system and their respective functions?

• The organs involved in the digestive system are the mouth, esophagus, stomach, small intestine, large intestine, liver, and pancreas. Their respective functions include breaking down food, absorbing nutrients, and eliminating waste.

• The organs involved in the digestive system are the skin, hair, and nails. Their respective functions include protecting the body, regulating temperature, and providing sensation.

• The organs involved in the digestive system are the brain, spinal cord, and nerves. Their respective functions include thinking, transmitting signals, and controlling movement.

• The organs involved in the digestive system are the heart, lungs, and kidneys. Their respective functions include pumping blood, breathing, and filtering waste.

How do digestive enzymes aid in the breakdown of food?

• They have no effect on the breakdown of food

• They cause the breakdown of large molecules into even larger molecules

• They speed up the chemical reactions that break down large molecules into smaller, more easily absorbed nutrients.

• They slow down the chemical reactions that break down large molecules

Explain the role of red blood cells in the circulatory system.

• Red blood cells store nutrients in the circulatory system.

• Red blood cells produce insulin in the circulatory system.

• Red blood cells transport oxygen and carbon dioxide in the circulatory system.

• Red blood cells regulate body temperature in the circulatory system.

What is the function of the small intestine in the digestive system?

• Absorption of nutrients

• Production of stomach acid

• Storage of waste

• Regulation of blood sugar levels

Discuss the role of calcium in bone structure and health.

• Calcium only affects muscle function, not bone structure

• Calcium provides the necessary mineral for bone formation and strength.

• Calcium has no impact on bone health

• Excessive calcium intake can weaken bones
