1. Understanding the Circulatory System: The circulatory system is responsible for the movement of blood throughout the body, delivering oxygen and nutrients to cells and removing waste products. 2. Identifying the Main Organs: The main organs of the circulatory system include: - Heart: The heart...
The lymphatic system became separate from the closed circulatory system (from its venous part) of vertebrates in the course of evolution. In man, vertebrates, and some invertebrates (arthropods and mollusks) the heart is the main organ of the circulatory system. The vessels that carry blood from...

Thecirculatory systemis one of the first functional organ systems formed during vertebrate embryonic development and can be divided into three main vessel systems. The arterial system carries blood away from the heart, with larger arteries feeding into progressively smaller diameter arteries,arterioles, ...
