Let's solve this step by step.

We are asked to complete a table about the three types of muscles in the human body: Cardiac, Skeletal, and Smooth muscle. We need to drag the correct information (including images and labels) into the appropriate columns based on their characteristics.

Step 1: Understand the Three Types of Muscles

1. Cardiac Muscle
- Found only in the heart.
- Involuntary – not under conscious control.
- Striated (striped) appearance.
- Works continuously to pump blood.

2. Skeletal Muscle
- Attached to bones; responsible for movement.
- Voluntary – we can control it consciously.
- Striated (striped).
- Examples: biceps, quadriceps.

3. Smooth Muscle
- Found in internal organs (e.g., intestines, blood vessels).
- Involuntary – not under conscious control.
- Non-striated (smooth appearance).
- Controls functions like digestion and blood flow.

Step 2: Analyze the Images and Labels Provided

Below the table, we have:

- A heart image → Cardiac muscle
- An intestinal tract image → Smooth muscle (in digestive system)
- A skeletal muscle image (like a bicep) → Skeletal muscle
- Three microscopic views:
- One with striations and long fibers → likely skeletal or cardiac
- One with spindle-shaped cells without striations → smooth muscle
- One with short, branched, striated cells → cardiac muscle
- Labels: "Voluntary", "Involuntary" (used twice)

Step 3: Match Each Type of Muscle to Its Characteristics

#### ✔ Cardiac Muscle:
- Location: Heart
- Control: Involuntary
- Microscopic structure: Striated, branched cells
- Image: Heart and the microscopic view with branched, striated cells

#### ✔ Skeletal Muscle:
- Location: Attached to bones
- Control: Voluntary
- Microscopic structure: Long, cylindrical, striated cells
- Image: Biceps-like muscle and the long, striated fibers

#### ✔ Smooth Muscle:
- Location: Walls of internal organs (e.g., intestines, blood vessels)
- Control: Involuntary
- Microscopic structure: Spindle-shaped, non-striated
- Image: Intestines and the spindle-shaped, non-striated cells

Step 4: Fill in the Table

We already have "INVOLUNTARY" in the Cardiac Muscle column.

Now fill the rest.

| CARDIAC MUSCLE | SKELETAL MUSCLE | SMOOTH MUSCLE |
|----------------|------------------|---------------|
| INVOLUNTARY | VOLUNTARY | INVOLUNTARY |
| Heart | Skeletal muscle (biceps) | Intestines |
| Branched, striated cells | Long, striated fibers | Spindle-shaped, non-striated cells |

---

Final Answer:

Here is the completed table:

| CARDIAC MUSCLE | SKELETAL MUSCLE | SMOOTH MUSCLE |
|------------------------|-----------------------------|------------------------------|
| INVOLUNTARY | VOLUNTARY | INVOLUNTARY |
| Heart (image) | Skeletal muscle (biceps) | Intestines (image) |
| Branched, striated cells | Long, striated fibers | Spindle-shaped, non-striated cells |

> 💡 Note: The term "INVLUNTARY" appears twice in the image — one next to the heart, one next to smooth muscle, and another label says "VOLUNTARY". These should be dragged accordingly.

Summary of Drag-and-Drop Actions:

- Cardiac Muscle Column:
- Add: "Heart" image
- Add: "Branched, striated cells" image
- Already has: "INVOLUNTARY"

- Skeletal Muscle Column:
- Add: "Skeletal muscle (biceps)" image
- Add: "Long, striated fibers" image
- Add: "VOLUNTARY"

- Smooth Muscle Column:
- Add: "Intestines" image
- Add: "Spindle-shaped, non-striated cells" image
- Add: "INVOLUNTARY"

✔ This completes the table correctly based on muscle type, control, location, and structure.
