Introduction: Anatomy and Physiology

Anatomy has to do with the forms and structures of the body; and in this case, the bodies of farm animals. It is closely related to physiology which deals with the functions of the forms and parts of the body. In anatomy, some of the systems that maintain the body include- the circulatory system, the reproductive system, the respiratory system, the nervous system and the digestive system.

Circulatory System

This system involves all the organs and tissues which are concurred with the movement of materials from one part of the body to another where they are either used or removed. These organs and tissues include the heart, the blood and the blood vessels.

•   The Heart

The heart is one of the most powerful organs in the circulatory system. It helps to pump blood round the body. Each pumping action of the heart is known as heartbeat.

•   The Blood

Blood is a fluid tissue. It is made up of two parts. The fluid plasma and the blood cells are corpuscles. There are three blood cells. These are erythrocytes (RBC), Leucocytes (WBC) and Thrombocytes (The blood platelets).

•   The Blood Vessels

The blood vessels are the network of spaces in the body through which materials are moved from one part of the body to the other with the aid of blood. There are three types of blood vessels. These are the artery, the vein and capillaries…
