All living things are organized. For this question, think about the levels of organization in the human body: organ system, organ, tissue, cell, molecule, atom. First, choose any organ system that we covered this semester, and explain its role in the body. Next, choose any organ in that system, and explain its specific function within the system. Next, choose any tissue type in that organ, and explain how it specifically helps the organ do its job. Next choose any cell type in that particular tissue, and explain how it contributes to the tissue’s function. Finally, choose any molecule (or atom) found in that specific cell and explain what the cell uses that molecule for.

Exocytosish. EndocytosisMUSCLE ACTIVITY, CONTRACTION, and MOVEMENT1. What are the five major functions of muscles in the body?2. What are the three types of muscle tissues and how do they differ anatomically?3. What are the actin and myosin? What are their roles in muscle movement?REFERENCES:

E OL 7.3.1 Unit 7.3 Explore 1 pg 490-495 1. Explain -- Identify a change in your environment that might affect homeostasis. Explain using the terms stimulus, control center, set point, effectors, and imbalance in your answer. 2. Model -- Refer to the control system diagram shown in Figure 1 (pg 490) to draw a model that shows how sweating can help body temperature return to normal. You can complete this by going to Insert > Drawing > +New in the space below OR Draw your model on paper. Take a clear picture. Then insert the picture by going to Insert > Image > Upload OR Camera OR Drive) 3. Complete the statement about negative feedback loops with the following words: control center effectors receptors set point Shivering and sweating are two parts of the same negative feedback loop with temperature as the stimulus that triggers its activity. When replace with answer. In the skin and body core detect an imbalance in temperature, they said nerve impulses to the replace with answer. The…
