The Circulatory System

The blood contains the oxygen, platelets, nutrients, red and white blood cells, hormones which are all important materials for metabolism.

Blood contains nutrients from the foods you eat and oxygen from the air you breathe. It also

Blood is a bodily fluid that transports oxygen and nutrients to the cells within the body. Blood has plasma that lets the different types of blood travel round the body. Plasma contains proteins that have different functions for the blood- clotting, transporting and defence organisms and osmotic organisations. The plasma carries the red blood cell which has a elastic membrane so it can fit through the small capillaries within the body. Red blood cells can be also known as erythrocytes they don’t have a nucleus when they are matured which gives a bigger space for oxygen, although as there is no nuclei the red blood cells can’t divide so they only live for around 120 days. Red blood cells gain their colour from haemoglobin, oxygenated blood which is known as arterial blood which flows through the arteries coming from the heart and

The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. The

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,

The Circulatory system is responsible for the transport of blood throughout the body. The Circulatory system has many organs. The main components are the heart, the blood, and the blood vessels. It also consists of arteries, arterioles,

Blood is a highly specialized complex connective tissue with a unique fluid of variable composition circulating through the heart, arteries, capillaries, and veins, known as the vascular system of the body (???). Blood approximately accounts of 8% of the body weight, with female body consists of 4-5 litres while males have around 5-6 litters. This variation is mainly due to the difference in body size between men and women (@@@). Human blood has a pH of 7.35-7.45, this makes the blood to be basic in nature. The viscous nature of blood makes it more resistant to flow than water. Unless blood is viscous, it can strain the heart and lead to severe cardiovascular problems (@@@). Due to the presence of high oxygen in arteries,

Blood is also a type of connective tissue. This consists of thrombocytes, red and white blood cells which is in a fluid matrix known as the plasma. This is a transport system which helps protect the body from infections. The immune system has white blood cells called leukocytes these defend the body from infectious diseases. Blood is also mainly responsible for transporting materials around the body remove waste material from cells and bring them nutrients.

1.The fluid surrounding tissue cells is called? interstitial fluid.2.What are the functions performed by the circulatory system?-The circulatory system supplies oxygen and nutrients to our body by working with the respiratory system.- It also helps carry waste and carbon dioxide out of the body3.What is the fluid type that holds many of the human body fluids?

The Education portal states that the most important connecting tissues throughout the human body is blood. It is in the category of connecting tissue due to it being made up of non-living fluid in which a living cell is deferred. Plasma which is the blood matrix around the cells makes up 55% of the blood volume within our body. There are three living cells in white blood cells, red blood cells and platelets they account for the remaining 45% of blood volume within the body. Blood has three main functions transportation, regulation and protection.

Blood has many functions and is a complex structure of cells and fluid. It helps fight bacteria, protect the body from infection, carry valuable sources of minerals and nutrients around the body, dispose of waste materials, keeps the body temperature regulated and helps with glandular distribution of hormones and enzymes.

The blood is categorised as a connective tissue which is one of the primary tissues found in our bodies. Connective tissue are made of tendons and ligaments that connect the tissue together, as well as bone and cartilage to support the body. This is why connective tissues are described as tissues that protect organs and maintain the form of the body. Blood is classified as this type of tissue because the blood has the same origin as the other connective tissue types and the other reason is because the body like the tissue connects the systems of the body together transporting nutrients, energy, and excreting waste products.

Blood is a liquid connective tissue, that transports substances through the body. It also helps main homeostasis of nutrient, gases and waste. Blood consists of plasma, red blood cells, white blood cells and platelets. A human body contains average of four to five litres of blood. (Taylor, 2017)
