- Tissue
- Organ system
Pia reads the muscle card. A sample shows stripes, one nucleus in the center of each cell, and no voluntary control. Which tissue is it?
- Nervous tissue
- Smooth muscle
- Cardiac muscle
- Skeletal muscle
Ren reads the muscle card. A sample from the wall of the intestine has no stripes and one central nucleus per cell. Which tissue is it?
- Nervous tissue
- Skeletal muscle
- Smooth muscle
- Cardiac muscle
Tala reads the muscle card. A sample has stripes, many nuclei along each cell's edge, and voluntary control. Which tissue is it?
- Cardiac muscle
- Skeletal muscle
- Smooth muscle
- Nervous tissue
Ari studies a model map. In the model, the circulatory system stops collecting carbon dioxide from muscle cells. What does the respiratory system then have less of to release?
- Carbon dioxide to release into the air
- Oxygen to release into the air
- Nothing to release, since the lungs make their own carbon dioxide
- Nutrients to release into the air
Map (model, not to scale)
Three boxes. The digestive system sends an arrow to the circulatory system, marked nutrients. The respiratory system sends an arrow to the circulatory system, marked oxygen.
Bo studies a model map. Which system receives a supply from both the digestive system and the respiratory system?
- The digestive system
- Neither, since each sends supplies straight to cells
- The respiratory system
- The circulatory system
