Transport System in Animals
Transport System in Animals The transport system, also known as the circulatory system, is responsible for the transportation of essential substances, such as oxygen, nutrients, hormones, and waste products, throughout an animal's body. It helps maintain homeostasis by distributing these substances and removing waste products from cells. The transport system typically consists of three main components: a circulatory fluid (such as blood), a system of vessels (such as arteries, veins, and capillaries), and a pumping organ (such as the heart) that helps move the circulatory fluid. Here are a few examples of transport systems in different animal groups: 1. Humans: In humans, the circulatory system consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps oxygenated blood from the lungs to the rest of the body through arteries. Oxygen and nutrients are exchanged with body tissues at the capillary level, and deoxygenated blood is then ret...
