5 The Integumentary System FOCUS: The integumentary system consists of the skin‚ hair‚ nails‚ and a variety of glands. The epidermis of the skin provides protection against abrasion‚ ultraviolet light‚ and water loss‚ and produces vitamin D. The dermis provides structural strength and contains blood vessels involved in temperature regulation. The skin is attached to underlying tissue by the hypodermis‚ which is a major site of fat storage. CONTENT LEARNING ACTIVITY Hypodermis ❛❛The hypodermis

INTEGUMENTARY SYSTEM The integumentary system consists of the skin and accessory structures‚ such as hair‚ nails‚ sudorifenous gland (sweat gland) and sebaceous gland (oil gland). Integument means covering‚ and the integumentary system is familiar to most people because it covers the outside of the body and is easily observed. FUNCTIONS OF THE INTEGUMENTARY SYSTEM 1. Protection The skin provides protection against abrasion and ultraviolet light. It prevents the entry of microorganisms

The respiratory system of the horse is well adapted to athletic exercise‚ with unrestricted upper airway diameters‚ and a large lung capacity afforded by 18 ribs. These combine to enable air intakes of up to 1800 litres per minute in a galloping horse. Volumes of up to 300 litres of blood are pumped at high pressure through small lung capillaries surrounding 10 million air sacs to take up and deliver over 70 litres of oxygen per minute to the working muscles at the gallop. As a result‚ any restriction

The endocrine system is very dynamic and has ties to most‚ if not all of the other major systems of the body. It is responsible for production of hormones and the regulation of them as well. These hormones act as chemical messengers within the body. Through several differing mechanisms‚ they are able to trigger very specific responses in target cells or organs. This is what enables the endocrine system to guide growth‚ development‚ reproduction‚ and behavior‚ among many others as well.

The respiratory system is composed of the nasal cavity‚ nostril‚ oral cavity‚ pharynx‚ larynx‚ trachea‚ carina of trachea‚ right main bronchus‚ right lung‚ left main bronchus‚ left lung‚ and diaphragm. These major organs collectively work together to give the body oxygen and eliminate carbon dioxide as we breathe. In order for the respiratory system to be fully capable of function‚ four procedures (pulmonary ventilation‚ external respiration‚ transport of respiratory gases‚ internal respiration)

Cardiovascular system: The circulatory system: The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart‚ arteries‚ capillaries and veins. As blood begins to circulate‚ it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen. This is important for

The Endocrine system helps to maintain homeostasis by secreting hormones into the bloodstream‚ which travels throughout the body. This system regulates activities such as growth and development and influence emotions and behavior. The relationship of this system alongside the other body systems is how the body maintain a stable equilibrium‚ regulating the activity of the organ systems. Nervous - The endocrine system acts as a communication tool within the human body‚ working alongside with the nervous
