Okay, RYAN, let's break down the systems in a dissected fowl again, focusing on the plain text format. Digestive System: Food travels down the esophagus to the crop for storage. It then moves to the proventriculus (glandular stomach) for chemical digestion, followed by the muscular gizzard for grinding. Nutrient absorption occurs in the small intestine, and water absorption in the large intestine. Waste exits via the cloaca*. Respiratory System: Fowl have relatively small, rigid lungs and a unique system of air sacs* that extend throughout their body. Air flows unidirectionally through the lungs, allowing for highly efficient gas exchange during both inhalation and exhalation, which supports their high metabolic rate. Circulatory System: Fowl have a closed circulatory system with a four-chambered heart* (two atria, two ventricles). This complete separation of oxygenated and deoxygenated blood ensures efficient oxygen delivery to tissues, vital for their active lifestyle. Blood is pumped from the heart to the lungs, then back to the heart, and finally to the rest of the body. Last free one today — make it count tomorrow, or type /upgrade for unlimited.
