what is the difference between the human vascular system and that of the starfish?

They do not have a circulatory system because they do not have a heart or blood that circulates nutrients. Sea Stars have two stomachs while humans only have one. They move very slowly and with the aid of tube feet and their water vascular system that humans do not have.

The blood vessels are part of the circulatory system and function to transport blood throughout the body. The most important types, arteries and veins, carry blood away from or towards the heart, respectively. All blood vessels have the same basic structure.

Anatomical terminology 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.

Difference between Vessels and Tracheids. Vessel is a syncyte, formed by the piling up of many cells. Tracheids are not syncyte, they are individual cells. Individual cells (vessel elements) are shorter than tracheids.

This system has three main components: the heart, the blood vessel and the blood itself. The heart is the system's pump and the blood vessels are like the delivery routes. Blood can be thought of as a fluid which contains the oxygen and nutrients the body needs and carries the wastes which need to be removed.

What characteristics distinguish echinoderms from other invertebrates? Their rough shiny appearance; water vascular system, bilateral larvae turns radially symmetrical when adult. And in statfish "skin gills" for respiration and excretion. List three examples of the phylum Echinoderma, other than the starfish.

One of the major difference between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart. Read on to explore what are arteries and veins and the difference between arteries and veins.

Arteries are blood vessels that carry blood away from the heart. This blood is normally oxygenated, with the exception of blood in the pulmonary artery. Arteries typically have a thicker tunica media than veins, containing more smooth muscle cells and elastic tissue.

The main difference between vascular and nonvascular plants is that a vascular plant has vascular vessels to carry water and food to all the different parts of the plant. ... Nonvascular plants are most commonly found in moist environments, which ensures they get enough water without relying on roots.

The cardiorespiratory system consists of the heart and blood vessels, which work with the respiratory system (the lungs and airways). These body systems carry oxygen to the muscles and organs of the body, and remove waste products, including carbon dioxide.

Open circulatory systems are simpler and contain open-ended vessels that help transport blood. On the other hand, closed circulatory systems are more complex and involve different types of vessels that are all connected, resulting in the continuous flow of blood within the system.

Differences between Arteries and Veins. Arteries and veins are two of the body's main type of blood vessels through which blood flow in the body. The arteries carry oxygenated blood away from the heart while the veins carry deoxygenated blood from the tissue capillaries back towards the heart.

For example, the heart and the blood vessels make up the cardiovascular system. They work together to circulate the blood, bringing oxygen and nutrients to cells throughout the body and carrying away carbon dioxide and metabolic wastes.

Veins differ from arteries in structure and function. For example, arteries are more muscular than veins, veins are often closer to the skin, and veins contain valves to help keep blood flowing toward the heart, while arteries do not have valves and carry blood away from the heart.

Things to remember. The circulatory system delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood on different sides. The types of blood vessels include arteries, capillaries and veins.
