Identify Major Organs

William Li mentions the blood vessels in his talk. Human’s body is literally packed with them. The smallest blood vessels are called capillaries, it is the vessels of life and are feeding cancer cells, bringing oxygen and nutrients. Also, it can be the vessels of death. We have got nineteen million of them in our bodies. Blood vessels are adapt our bodies no matter where they grow in our bodies.

The heart is one of the most important organs in the body. The heart is responsible for pumping blood throughout the human body supplying the tissue with oxygen and nutrients and removing carbon dioxide and waste. If the heart does not supply blood and oxygen to the organs and tissues, they will die.

artery or vein. The tube in this artery is connected to a mechanical pump that

37. At any given time, most blood is in what vessels? (arteries or veins?) arteries

The cardiovascular system, however, would not be able to effectively complete these functions without help from what is sometimes referred to as the body’s hardest-working organ- the heart. Approximately the size of a fist, the heart is contains four chambers (the uppermost are called the atria and the lowermost are called the ventricles) and four valves. Additionally, the heart is surrounded by the pericardium, a structure that serves to protect the heart, keep the heart stabilized in the chest, and

The heart pumps the blood around the body through the blood vessels which is made of mostly veins and capillaries. The blood carries the dissolved oxygen around the bodily

The heart is a major organ in the body, this organ pumps blood around the body, through veins, capillaries and arteries. The blood carries oxygen to our cells and also carries waste products which include water and carbon dioxide, which are products of respiration. Blood also helps spread out salts, enzymes, urea, nutrients, hormones and heat across the body.

The heart, blood and blood vessels make up the basis of the cardiovascular system also known as the circulatory system. The average human body contains approximately 5 litres of blood which is carried around the body via a network of blood vessels split into three types; arteries, veins and capillaries. The arteries are the largest of the three vessels and carry blood away from the heart. Veins carry blood to the heart and are smaller than arteries, then finally the smallest vessels known as capillaries distribute the oxygen rich blood to organs whilst simultaneously picking up the waste carbon dioxide and water from the organs to transport back to the heart where it can be pumped into the lungs to be exhaled.

Explanation: A). Blood carries oxygen from the lungs to the cells of organs and tissues and carbon dioxide from those organs and tissues to the lungs inside our body.

Blood is made up of straw coloured plasma, the matrix, in which various types of blood are carried. Plasma is mainly water where substances are carried such as oxygen and carbon dioxide, nutrients such as glucose and amino acids, salts, enzymes and hormones. Also there is a combination of important proteins which help with blood clotting, transport,

Blood is a liquid connective tissue as it is made up of living cells (red and white). Oxygen is transported in red blood cells, attached to a protein called haemoglobin while nutrients, including glucose, are dissolved in the

Arteries carry blood away from the heart and are the largest of the blood vessels. Arteries are the largest and most muscular because of their function. They carry oxygenated blood away from the heart and therefore has force placed on them as the heart contracts and pumps. Veins carry blood back to the heart and lungs to be oxygenated again. The walls of veins are thin, elastic, and the flow of blood through veins are much slower and rely on surrounding muscles to push blood back to the heart. (They also have valves to prevent the backflow of

The heart pumps blood vigorously through the vessels to all parts of the body, nourishing the organs

Blood is one of the most vital components of the human body. The blood carries many functions such as to supply oxygen to the bodies tissues, remove metabolic waste products, regulate our core temperature as well as fighting infection and foreign bodies (Glover, 1997). The cardiovascular system is composed of the heart and its vessels. The heart is an involuntary muscle which receives blood to the atrias, which is then pumped via the ventricles. The vessels are composed of three main types. Arteries, veins and capillaries; all which transport blood throughout the entirety of the body. The constant action of both the vessels and heart ensure that the body receives a continuous supply of blood, keeping us within our homeostatic limits.

The first one is called plasma is the largest section of your blood is made up mostly of water in the intravascular fluid (inside the blood vessels) of the extravascular cell (around the outside of the cell).
