Equine cardiovascular and respiratory system

The right atrium also houses the sinoatrial node. The outer layer is composed of relatively inelastic connective tissue and is termed the parietal layer. The heart itself is split up into 4 chambers, the blood first enters the heart through the Pulmonary Vein into the Left Atrium which is the first chamber, there is a valve called the bicuspid valve which acts as a one way valve allowing the blood to then flow when ready into the Left Ventricle.

The remainder of the blood travels throughout the body. The fuel is converted into nutritional energy that powers the muscles. The ligaments are composed of a grouping of many long, thin collagenous fibers packed closely together, forming a dense connective tissue.

As the tendon structures stretch and relax, they can also be subjected to damage at a microscopic level, which once again healing can strengthen. Density and mineral content of bone are modified in response to conditioning, which is a direct result of the workload stresses to which the bone is exposed.

As indicated, the number of breaths taken per minute is referred to as respiration rate or respiration frequency. The movement of the myosin filaments against the actin filaments is the basis of muscle contraction.

The primary electrolytes lost during sweating include sodium, potassium, and chloride. Physiology and Locomotion The Hoof The horse is unique among domestic livestock in that it does not have a cloven hoof.

Systemic Circulation Arteries of the systemic circulation transport oxygenated blood from the left ventricle to organs and tissues of the body. Type I fibers are used for activities in which it is necessary to resist fatigue by working at a lower level of intensity.

If the bone is not allowed time to repair itself, the microscopic damage can accumulate until the bone becomes fragile. It supplies adjacent cervical musculature.

A small pocket inside them called the nasal diverticulum, filters debris with the help of hairs that line te inner nostril. They supply small branches to the tracheaoesophagus and adjacent muscles. The trachea is a tube that takes air from the oral cavity and into the lungs.

Alveolar Each Alveolar duct then becomes an Alveolar sac and it is through these that diffusion through the thin Alveolar sac wall takes place, this process allows oxygen to enter the bloodstream via the pulmonary vein and go directly to the heart and also allows for carbon dioxide to leave the blood stream via the pulmonary artery.

Equine Exercise Physiology

The cardiovascular system in the horse is a transport system comprising a muscular pump - the heart - a system of blood vessels called veins, arteries and capillaries, as well as lymphatic vessels and structures.

Circulatory System of a horse FONTS Organs Heart The body systems that the circulatory interacts with are cardiovascular and respiratory. The cardiovascular system includes the heart which is needed for the blood to be pumped through the body.

Aug 07,  · The "circulatory system of the horse" consists of the heart, the blood vessels, and the blood. The equine heart is a muscular pump that circulates blood throughout the body. It is more globoid in shape than the human heart and consists of four chambers: the left and right atria, and the left and right ventricles.
