The circulatory system consists of blood, vessels, and a pump (heart) to circulate blood throughout the body. Blood transports gases, nutrients, wastes, and more, and helps fight diseases using white blood cells. The main types of vessels are arteries, veins, and capillaries. Arteries carry blood away from the heart while veins carry blood back to the heart. Capillaries are the smallest blood vessels where nutrients/gases are exchanged. The heart acts as the pump with four valves to ensure one-way blood flow.

Introduction
The circulatory system consists of the heart, blood, arteries, veins, capillaries, and lymphatic system. The heart pumps blood through the arteries, which branch into smaller arterioles and capillaries where nutrients and oxygen are delivered and waste is removed. The veins and venules then return deoxygenated blood back to the heart. The lymphatic system works with the circulatory system to collect and return fluid that leaks from capillaries back to the bloodstream. Blood is the main transport medium and carries oxygen, carbon dioxide, nutrients, waste, water, white blood cells, platelets, hormones, heat, and buffers throughout the body to maintain homeostasis.

Blood travels from the heart through arteries, then into capillaries where nutrients and waste are exchanged, then into veins which return blood back to the heart.
Circulatory System BY: EMYLIE LANTORIA.pptx
The document discusses the circulatory systems of various organisms. It describes two main types of circulatory systems - open systems where blood mixes with interstitial fluid, and closed systems where blood remains confined to vessels. Vertebrates have a closed dual circuit system, with one circuit moving blood to and from the lungs, and another moving blood to and from the rest of the body. The human cardiovascular system consists of a heart that pumps blood through arteries, capillaries and veins in two separate circuits - the pulmonary and systemic circuits.

Insects have an open circulatory system where blood, or hemolymph, flows freely through the body cavity known as the hemocoel. The hemocoel is divided into three sinuses - the dorsal, ventral, and visceral sinuses - by two diaphragms. The main organ of circulation is the dorsal blood vessel, which consists of the anterior aorta and posterior heart. During diastole, the heart expands and draws hemolymph into the heart through openings called ostia, and during systole the heart contracts to pump hemolymph through the aorta to bathe tissues and organs. Hemolymph transports nutrients, removes waste, regulates temperature, and protects the insect from pathogens.
