Illustration of the digestive system with labeled parts and digestion steps.

It looks like you've uploaded an image of a human digestive system diagram with a fill-in-the-blank worksheet. The task involves labeling parts of the digestive system and completing sentences about digestion.

Since I can't view images directly, I’ll help you solve this based on standard knowledge of human anatomy and digestion. Here's how to complete the worksheet:

---

1. Digestion begins in your ________ when food enters your body. As you chew, your ________ mix with food and begin to break it down.

✔ Answer:
- First blank: mouth
- Second blank: saliva

> Explanation: Digestion starts in the mouth where saliva (produced by salivary glands) mixes with food. Saliva contains enzymes like amylase that begin breaking down carbohydrates.

---

2. Your ________ muscles squeeze the food to move it into smaller pieces. Chewing also helps the food and liquid mix with saliva.

✔ Answer:
- Blank: jaw or cheek (but most accurate is jaw)

> Explanation: The jaw muscles (especially masseter and temporalis) are responsible for chewing (mastication), which breaks food into smaller pieces.

---

3. A long tube that connects your mouth to your stomach.

✔ Answer:
- This refers to the esophagus

> Explanation: The esophagus is a muscular tube that transports food from the mouth to the stomach via peristalsis (wave-like muscle contractions).

---

4. Next, the food moves to your ________, where food is mixed and churned into a thick liquid called chyme.

✔ Answer:
- Blank: stomach

> Explanation: In the stomach, food is mixed with gastric juices (including hydrochloric acid and pepsin) and turned into a semi-liquid substance called chyme.

---

5. From there, the chyme goes to your ________, where nutrients are absorbed into the bloodstream and moved into your cells.

✔ Answer:
- Blank: small intestine

> Explanation: Most nutrient absorption occurs in the small intestine, especially in the duodenum, jejunum, and ileum. Villi and microvilli increase surface area for absorption.

---

6. The rest of the food moves into your ________, where water is absorbed and waste is stored before being removed from the body.

✔ Answer:
- Blank: large intestine (or colon)

> Explanation: The large intestine absorbs water and electrolytes from undigested food, forming solid waste (feces). Waste is stored in the rectum until excretion.

Final Answer Summary:

1. Digestion begins in your mouth when food enters your body. As you chew, your saliva mixes with food and begins to break it down.
2. Your jaw muscles squeeze the food to move it into smaller pieces. Chewing also helps the food and liquid mix with saliva.
3. A long tube that connects your mouth to your stomach: esophagus
4. Next, the food moves to your stomach, where food is mixed and churned into a thick liquid called chyme.
5. From there, the chyme goes to your small intestine, where nutrients are absorbed into the bloodstream and moved into your cells.
6. The rest of the food moves into your large intestine, where water is absorbed and waste is stored before being removed from the body.
