Concepts in question:

• The Digestive system is the system by which ingested foods is acted upon by physical and chemical means to provide the body with absorbable nutrients and to excrete waste products; in mammals, the system includes the alimentary canal extending from the mouth to the anus, and the hormones and enzymes assisting in digestion.
• The Circulatory System is the system of organs and tissues, including the heart, blood, blood vessels, lymph, lymphatic vessels, and lymph glands, involved in circulating blood and lymph through the body.
• The Respiratory System is the system by which oxygen is taken into the body and an exchange of oxygen and carbon dioxide takes place; in mammals the system includes the nasal passages, pharynx, trachea, bronchi, and lungs.
• The Gastrointestinal Tract/Digestive Tract is the system of organs within multicellular animals which takes in foods, digests it to extract energy and nutrients, and expels the remaining waste.
• Liver is a large, reddish-brown, glandular organ located in the upper right side of the abdominal cavity, divided by fissures into five lobes and functioning in the secretion of bile and various metabolic processes.
• Pancreas is a gland, situated near the stomach, that secretes a digestive fluid into the intestine through one or more ducts and also secretes the hormone insulin.
• Gallbladder is a pear-shaped, muscular sac attached to the undersurface of the right lobe of the liver, in which bile is stored and concentrated.
• Heart is a hollow, pump-like organ of blood circulation, composed of mainly of rhythmically contractile smooth muscle, located in the chest between the lungs and slightly to the left and consisting of four chambers: a right atrium that receives blood returning from the body via the superior and inferior vena cavae, a right ventricle that pumps the blood through the pulmonary artery to the lungs for oxygenation, a left atrium that receives the oxygenated blood via the pulmonary veins and passes it through the mitral valve, and a left ventricle that pumps the oxygenated blood, via the aorta, throughout the body.
• Blood vessels are any of the vessels, as arteries, veins, or capillaries, through which the blood circulates.
• Blood is the fluid that circulates in the principal vascular system of human beings and other vertebrates, in humans consisting of plasma in which the red blood cells, white blood cells, and platelets are suspended.
• The Nose is the part of the face or facial region in humans and certain animals that contains the nostrils and the organs of smell and functions as the usual passageway for air in respiration: in humans it is a prominence in the center of the face formed of bone and cartilage, serving also to modify or modulate the voice.
• The Mouth is the opening through which an animal or humans takes in food.
• The Throat is the passage from the mouth to the stomach or to the lungs, including the pharynx, esophagus, larynx, and trachea. The Pharynx is the tube or cavity, with its surrounding membrane and muscles, that connects the mouth and nasal passages with the esophagus.
• Larynx is a muscular and cartilaginous structure lined with mucuous membrane at the upper part of the trachea in humans, in which the vocal cords are created.
• Trachea is the tube in humans and other air-breathing vertebrates extending from the larynx to the bronchi, serving as the principal passage for conveying air to and from the lungs; the windpipe.
• Bronchus are either of the two main branches of the trachea.
• Lungs are an analogous organ in certain vertebrates, as arachnids or terrestrial gastropods. Or they are either of the two saclike respiratory organs of the thorax of humans and the higher vertebrates.
• Esophagus is the muscular passage connecting the mouth or pharynx with the stomach in invertebrate and vertebrates animals; gullet.
• Small intestine is a intestine, the narrow, longer part of the intestines, comprising of the duodenum, jejunum, and ileum, that serves to digest and absorb nutrients.
• Large Intestine is a intestine, shorter part of the intestine, comprising the cecum, colon, and rectum, that absorbs water from and eliminates the residues of digestion.
• Rectum is the comparatively straight, terminal section of the intestine, ending in the anus.
• Anus is the opening at the lower end of the alimentary canal, through which the solid refuse of digestion is excreted.
