Skull. Protects the brain and supports the facial structure.

Spine. Composed of vertebrae, it supports the body and protects the spinal cord.

Ribs. Protect the heart and lungs.

Limbs. Consists of bones like the femur, tibia, radius, and cannon bone, providing support and facilitating movement.

Joints. made up of cartilage and ligaments, connect the bones and allow for flexibility and movement. The skeletal system also stores minerals and produces blood cells in the bone marrow.

Respiratory system

The respiratory system is responsible for oxygen intake and carbon dioxide expulsion. It includes:

Nostrils and nasal passages. Filter and warm the air entering the body.

Larynx and trachea. Conduct air to the lungs.

Lungs. Main organs of respiration where gas exchange occurs.

Diaphragm. A muscle that contracts and relaxes to enable breathing.

Air travels from the nostrils through the trachea to the lungs, exchanging oxygen for carbon dioxide in the alveoli. Efficient respiration is crucial for energy production and overall health, especially in performance horses.

Digestive system

The digestive system processes food, absorbs nutrients, and eliminates waste. Key components include:

Mouth and teeth. Chew food and mix it with saliva.

Esophagus. Transports food to the stomach.

Stomach. Begins the breakdown of food with acids and enzymes.

Small intestine. Major site for nutrient absorption.

Cecum. A fermentation chamber where microbes break down fibrous plant material.

Large intestine. Absorbs water and forms waste.

Horses have a unique digestive system adapted for continuous grazing. Proper feeding practices are essential to prevent issues like colic and laminitis.

Circulatory system

The circulatory system transports blood, nutrients, oxygen, and waste products throughout the body. It includes:

Heart. A four-chambered organ that pumps blood.

Arteries. Carry oxygen-rich blood away from the heart.

Veins. Return oxygen-depleted blood to the heart.

Capillaries. Small vessels where nutrient and gas exchange occurs.
