Type Examples

3. The following paragraphs describe how the digestive system works. Fill in the missing words using the word list below.Digestion: Match the function with the part

Word list : esophagus, rectum, anus, villi, mouth, stomach, large intestine, bile, salivary glands, small intestine, pancreas

Digestion begins in the __________. Teeth chew the food, saliva wets the food and the __________________ makes saliva (spit) to begin the digestion of carbohydrates.

Food travels down the ________________ into the J-shaped ___________ where the following happens:

Churning (mixing of food and acid) Acid and pepsin (enzyme) work to digest protein

Next, food passes into the __________________ where digestion of protein, carbohydrate, and fats occurs. Food is absorbed. Tiny _________ increase the surface area for absorption in the intestine.

Three organs secrete (release) substances for digestion. The liver makes digestive enzymes and _________ which is stored in and released from the gall bladder. The ____________ also releases digestive enzymes into the small intestine.

The food passes into the colon or _________________ next. Here the water is absorbed. Vitamin K is produced.

Lastly, waste is stored in the ________________ and passed out the hole called the _______________.

6.Structure of the Heart: Label the following parts of the human heart on the diagram belowa. aortab. left atriumc. right ventricled. right atriume. left ventricle

For questions 1-3, fill in the name of the blood vessel.____________ 1. vessels which carry blood away from the heart.____________ 2. vessels which carry blood toward the heart.____________ 3. tiny blood vessels with walls that are only one-cell thick.

8. Label the figure correctly with the words from the list below. Choices: lung, diaphragm, trachea, bronchus, bronchiole, alveoli, larynx, nose.

10. Describe the function of each organ system:a) circulatory system:

b) nervous system:

c) digestive system:

g) respiratory system:

11. a) How does the human digestive system cooperate with the circulatory system?
