* **Body:** The pig’s body is generally cylindrical and muscular, adapted for efficient movement and weight bearing. The shape and size vary greatly between breeds.
* **Legs and Hooves:** Pigs have four legs, each ending in cloven hooves. These hooves are well-suited for walking on various terrains, including soft soil and pastureland. The dewclaws, small digits located higher on the legs, serve a limited weight-bearing function.
* **Tail:** The tail of a pig can be straight, curly, or docked (shortened). It plays a role in balance and social communication. Tail docking is a common practice in some farming systems to prevent tail biting.

Internal Anatomy: A Look Inside the Pig

Exploring the internal anatomy of a pig reveals the intricate systems that support its life processes. Here are some key internal organs:

* **Digestive System:** Pigs are monogastric animals, meaning they have a single-chambered stomach. Their digestive system includes the esophagus, stomach, small intestine, large intestine, liver, pancreas, and gallbladder. This system efficiently breaks down and absorbs nutrients from a variety of feed sources.
* **Respiratory System:** The respiratory system of a pig consists of the nasal passages, trachea, bronchi, and lungs. It is responsible for gas exchange, allowing the pig to take in oxygen and expel carbon dioxide.
* **Circulatory System:** The circulatory system includes the heart, blood vessels (arteries, veins, and capillaries), and blood. It transports oxygen, nutrients, hormones, and waste products throughout the body.
* **Excretory System:** The excretory system, composed of the kidneys, ureters, bladder, and urethra, filters waste products from the blood and eliminates them from the body in the form of urine.
* **Nervous System:** The nervous system, consisting of the brain, spinal cord, and nerves, controls and coordinates all bodily functions. It allows the pig to perceive its environment and respond to stimuli.
* **Skeletal System:** The skeletal system provides structural support and protection for the internal organs. It consists of bones, cartilage, and ligaments. The skeletal structure varies slightly between breeds.

Understanding these anatomical features, as illustrated in a comprehensive **diagram of a pig**, is fundamental for anyone working with these animals.
