Animal Anatomy and Physiology encompasses the study of the Animal Circulatory system and its branches. Hematology is defined as the clinical study of tissue that form blood and the collective learning of plasma itself. Blood is an absolute necessity for animals, being multi cellular organisms. Blood in the Animal Anatomy & Physiology plays a crucial role on many transport functions such as nutrient diffusion, oxygenation of organs and waste disposal.
Connective tissue is the main composition of blood. It is found in non-living fluid medium called plasma and is carried throughout the body of the animal. Animal blood serves three basic functions- to protect the body, regulate and transport vital nutrients and gas.
Transportation
As with any warm blooded organism, the blood is responsible for transporting two vital gasses in the physiology, Oxygen and Carbon Dioxide. Blood carries Oxygen and Carbon Dioxide to and from the lungs and tissues. In Animal Anatomy & Physiology, the function of blood is to transport the nutrient it absorbs from the gastric and intestinal track, bringing it to the liver for processing. It also transports the endocrine hormones to specific cells and is one of the main transport systems for excretory organs such as the kidneys, liver and skin. Animals also cool their bodies by circulating blood and dispersing heat through their skin while circulating.
Regulation
The promotion and insistence of homeostasis is the secondary function of blood in Animal Anatomy & Physiology. The acid levels of the body as well as the internal temperature of the animal are maintained by the blood by transporting excess heat through skin dissipation or vasoconstriction to conserve heat. Animal blood uses osmosis to maintain the electrolyte and protein levels of its body.
Protection
Blood is a crucial element in the immune system of an animal. The characteristics of blood cells vary, some will produce antibodies while other phagocytic and blood protein components like interferon are critical to maintaining immune system levels.
Physical characteristics of blood
Blood is a complex mixture of liquid and cellular elements and is denser compared to water. Plasma is the main suspension where the blood cells and cell fragments lay out and despite the nature of blood being connective tissue fibers are not present because it is dissolved during protein synthesis. If you look at blood through a centrifuge, blood is easily broken down into three distinct characteristics. Red blood cells will occupy the bottom of the centrifuge followed by your white blood cells or leukocytes and platelets then topped off by the plasma.
