Question

human body systems a 1.1.3 _ tissues conclusion questions - get stamp when complete! 1. what do you notice is the main difference between the structure of connective tissues and the structure of epithelium tissues? how do their structures relate to their function? 2. come up with an analogy of the levels of organization of life. (look at your building up notes from the first handout. stuck? look at the discussion question response at the bottom of mypltw 1.1.3 let’s get organized for an example!)

Explanation:

For the first question, connective tissues have a more dispersed cell - matrix structure with cells scattered in a large amount of extracellular matrix, which allows them to provide support, connection, and protection. Epithelium tissues are tightly packed cells forming continuous sheets, which enables them to act as barriers, for secretion, and absorption. For the second question, an analogy for the levels of organization of life could be a city. Cells are like individual people, tissues are like groups of people with similar jobs (e.g., a police department), organs are like buildings that house different groups (e.g., a police station), organ - systems are like city services (e.g., public safety), and the organism is like the whole city.

Answer:

1. Connective tissues have dispersed cells in a large extracellular matrix for support and connection. Epithelium tissues are tightly - packed cell sheets for barrier and secretion/absorption functions.
2. A city: cells are like people, tissues are like job - specific groups, organs are like buildings, organ - systems are like city services, and the organism is like the whole city.
