1Question

Name the four main types of tissues in the human body and give one function of each.

2Question

A student says the digestive system only breaks food into smaller pieces. Explain two additional roles of the digestive system besides mechanical breakdown.

3Question

Explain how the respiratory and circulatory systems work together to deliver oxygen to body cells.

4Question

A person cuts their skin and the area becomes red, swollen, and warm. Describe how the immune system responds to this injury and why these symptoms happen.

5Question

A patient has damage to the pancreas. Explain how this could affect both digestion and blood sugar regulation, and identify why the pancreas is considered an organ with multiple functions.

Answer Key

#	Answer
1	Epithelial tissue protects and covers body surfaces; connective tissue supports, connects, and binds body parts; muscle tissue contracts to produce movement; nervous tissue carries signals for communication and control.
2	The digestive system also chemically breaks food into molecules that can be absorbed, and it absorbs nutrients and water into the bloodstream. It also eliminates undigested waste from the body.
3	In the lungs, oxygen enters the blood during gas exchange. The circulatory system then pumps and transports this oxygen-rich blood through blood vessels to body cells. Cells use the oxygen for cellular respiration, and carbon dioxide produced by cells is carried back to the lungs for removal.
4	The body triggers an inflammatory response. Blood vessels near the cut widen, bringing more blood, immune cells, and healing materials to the area. This causes redness and warmth. Fluid may leak into the tissue, causing swelling. White blood cells help fight possible pathogens and begin repairing the tissue.
5	The pancreas produces digestive enzymes that help break down carbohydrates, proteins, and fats, so damage can reduce digestion and nutrient absorption. It also produces hormones such as insulin and glucagon, which regulate blood sugar levels. Therefore, pancreatic damage can cause both digestive problems and problems maintaining normal glucose levels. It is considered to have multiple functions because it acts as both a digestive gland and an endocrine gland.
