The circulatory system transports nutrients, oxygen, and hormones throughout the body and removes wastes. It includes the heart, blood, and three types of blood vessels - arteries, veins, and capillaries. The heart pumps blood through the vessels. Arteries carry blood away from the heart to capillaries, where nutrients and gases are exchanged with body tissues. Then veins carry blood back to the heart with waste products. This continuous circulation allows for transport and exchange of materials throughout the body.
Blood Vessels and Circulatory system Three principal categories of blood vessels:
Arteries: efferent vessels
Capillaries:
Veins: afferent vessels
Arteries and Arterioles
Three layers surrounding the lumen:
Tunica interna
Tunica media
Tunica externa
Structure of Capillaries
The blood vessels are the components of the circulatory system that transport blood throughout the human body. These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. They also take waste and carbon dioxide away from the tissues.

Blood is carried through the body via blood vessels. An artery is a blood vessel that carries blood away from the heart, where it branches into ever-smaller vessels.

Structure:
Most have the same basic structure:
– 3 layers surrounding a hollow lumen
There are three kinds of blood vessels: arteries, veins, and capillaries.
Each of these plays a very specific role in the circulation process/blood circulation.
Arteries transport blood away from the heart.
Veins return blood back toward the heart.
Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances.
The capillaries also connect the branches of arteries and to the branches of veins.
The walls of most blood vessels have three distinct layers: the tunica externa, the tunica media, and the tunica intima.

The presentation that will unable to create a clear cut concept regarding the Vessels the vascular system of the human body. It will let you know about the arteries, veins, capillaries how the exchange of nutrients and other substance takes place..and many more things related to the vessels of the body.
Powerpoint presentation about nutrient support. This has the process on how nutrients were taken, absorbed, utilized and how waste materials were eliminated in the body.

My project was to prepare a presentation on human circulatory system.
This is what it finally looked like .
Hope it comes of some use to you all .

Human cardiovascular system, organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes. It is a closed tubular system in which the blood is propelled by a muscular heart. Two circuits, the pulmonary and the systemic, consist of arterial, capillary, and venous components.
The primary function of the heart is to serve as a muscular pump propelling blood into and through vessels to and from all parts of the body. The arteries, which receive this blood at high pressure and velocity and conduct it throughout the body, have thick walls that are composed of elastic fibrous tissue and muscle cells. The arterial tree—the branching system of arteries—terminates in short, narrow, muscular vessels called arterioles, from which blood enters simple endothelial tubes (i.e., tubes formed of endothelial, or lining, cells) known as capillaries. These thin, microscopic capillaries are permeable to vital cellular nutrients and waste products that they receive and distribute. From the capillaries, the blood, now depleted of oxygen and burdened with waste products, moving more slowly and under low pressure, enters small vessels called venules that converge to form veins, ultimately guiding the blood on its way back to the heart.
1. Concept 30.1 The Circulatory system transports materials throughout the body
2. The Circulatory system The circulatory system transports nutrients, oxygen, and hormones throughout the body and carries wastes away from cells. The circulatory system includes the blood, heart, and blood vessels.
3. Blood & heart Blood is a type o connective tissue made up of cells and liquid parts. Blood is pumped through the body by the heart. The heart is a muscular organ with four chambers
4. BloodVessels Blood flows throughout the body in three types of blood vessels. Capillaries Arteries Veins
5. Capillaries Capillaries are microscopic vessels through which nutrients, oxygen, and wastes move between blood and interstitial fluid.
6. Arteries Arteries are thick-walled vessels that carry blood from the heart to the capillaries. The blood in arteries is under pressure, which helps to ensure that blood flows in the right direction.
7. Veins Veins are vessels that carry blood form the capillaries to the heart. They are larger than capillaries but not as thick as arteries. Blood in veins is under very little pressure. Blood is moved through veins by contractions of the surrounding skeletal muscles. Most veins contain valves that allow blood to flow only toward the heart.

9. The Chemical exchange between blood and body tissues takes place in the interstitial fluid. At the artery end of a capillary, blood pressure forces fluid out through the capillary walls into the interstitial fluid. Blood cells and large proteins are too big to pass through capillary walls, so they stay in the capillary.
10. At the vein end of the capillary, the drop in blood pressure allows most of the fluid to reenter the capillary. The rest of the fluid is collected by vessels that make up the lymphatic system. Once inside the lymphatic vessels, the fluid is called lymph. Eventually, lymph drains into the circulatory system near the heart, allowing the fluid to be reused.
