Anatomy and physiology of the cardiovascular system
Cardiovascular System
According to (smith.A2013).
The cardiovascular system includes the heart, blood vessels and also blood. Its role is to deliver nutrients and takes away any by-products from a person’s body. The cardiovascular system is the heart and it is a four-chambered pump that carries blood to the arteries these arteries then carries out clean and oxygenated blood to the tissue.

The blood
Definition
According to (dictionary.com 2002).
Blood is the fluid that circulates in the vascular system of human beings and, in a humans blood is consisting of plasma in which the red blood cells, white blood cells and platelets are suspended.
Two Parts of the blood.
Plasma …show more content…

Platelets do not contain a nucleus and can only survive in the body for a week and then a ‘Macrophages’ capture and digest them, platelets are also formed in the red bone marrow. (innerbody,2016)

The functions of blood
The bloods functions include:
Transportation – the blood carries other substances around the body inside the Arteries, Veins and Capillaries. The blood flows through the circulatory system and also dissolves gases such as oxygen and carbon dioxide.
Immunity and defence- white blood cells are cells that help fight infection. (Teachpe,2017).
Maintaining body temperature.
Destroys toxins from the body such as acids. (Ivy rose,2003)
Blood vessels
Definition
A blood vessel is a vessel in a human’s body in which blood circulates, Arteries carry the blood away from the heart and the very small branches are the Arterioles. The venules collect the blood from different organs, they unite to form veins.
The 5 types of blood vessels in the body are: (ref http://patient.info/health/the-heart-and-blood-vessels)
Arteries …show more content…

These small veins are called venules. Venules collect blood from capillaries and drain into veins.
5 - Veins are the blood vessels that carry blood back to the heart. They may contain valves which stop blood flowing away from the heart.
Describe the 3 main types of blood circulation? - https://www.reference.com/science/three-types-circulation-28f4fb9363b09f33

The three types main types of blood circulation are
1 - Systemic circulation
2 – Pulmonary circulation
3 – Portal circulation
These three systems work together for the proper oxygenation and blood flow throughout the body.

Systemic Circulation is when the network of vessels carry blood from the heart to the body and from the body back to the heart

Pulmonary Circulation is a network of vessels that carries blood to and from the lungs Portal Circulation is the network of arteries and veins that supplies blood to all the cells of the heart

Pathophysiology The present of a patent foramen ovale is required to permit blood flow across the septum into the left atrium, the patent duct arteriosus allows blood to flow to the pulmonary artery into the lungs. VSD allows a modest amount of blood to enter the right ventricle &pulmonary artery. Thus pulmonary blood flow is diminished.

Veins transport blood to the heart and lungs at low pressure after receiving it from the capillaries. Valves inside the veins keep blood moving in one direction. The human body's arterial system branches out from one main artery, the dorsal aorta. Like veins, arteries have three layers: an outer layer of tissue, an inner layer of epithelial cells and a layer of muscle in between.

The functions of the human cardiopulmonary system can be broken down into two, circulatory system and the respiratory system. The main goal of these two systems is to maintain homeostasis in our body. Homeostasis can be described as a type of condition where the internal continuity of an individual has to keep steadiness, regardless of any external changes from the outside environment. External changes from the outside environment may include factors such as excitement, stress, exercise, diet, and much more. Exercise can be carried out because the human body can endure a high level of exercise during a prolonged period of time.

In this process, the blood vessels of the patient would be fixed to those of a human donor of matching blood type. While the patient’s heart was open during surgery, the donor’s body would act as a blood oxygenator and the blood would be kept circulating via mechanical pump, in addition to the donor’s beating

Imagine having cerebral palsy and not being able to walk, talk, or even giving a simple wave. I am reading a book called Out of My Mind by Sharon Draper. It is about a girl that has cerebral palsy and she has a lot of ups and downs in her life. I think the theme of the book is stick up for your friends and here is why. First reason I think “stick up for your friends” is the theme because, Rose learns that being a good friend is something that is a good thing.

Also the lymphatic system stops fluid form building up in the tissues in our body and its acts as a filter for the blood and removes the pathogens and antigens from the blood. Role of the parts: Lymph nodes – Lymph nodes are enclosed, located around the lymph vessels. Lymph nodes are a key organ of the immune system and they make white blood cells which help fight off diseases. They also create antibodies to neutralize infections. They do this by producing lymphocytes protects the body from harmful microorganisms, unknown particles and removes litter from the lymph.

1. Explain the function of the heart, and the structure of the arteries veins and capillaries The heart is a key muscular organ, and is controlled by the autonomic nervous system. It transports blood to the body’s tissues via the circulatory system; blood provides the body with oxygen, nutrients and also assists in the removal of carbon dioxide and metabolic wastes, hormones are transported throughout the body by plasma. Arteries, arterioles, veins, capillaries and valves, are the blood vessels which are responsible for transporting the blood throughout the body.

INTRODUCATION THROMOS DEFINATION Thrombosis is the making of a blood clot inside a blood vessel, stop the flow of blood through the circulatory system. When a blood vessel is injured, the body uses platelets and fibrin to form a blood clot to prevent blood loss from the body. Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus[1]

The small saphenous vein (SSV) is a superficial vein in the leg. It originates from the lateral side of the dorsal venous arch passes behind the distal end of the fibula and up the back of the leg to penetrate deep fascia and join the popliteal vein posterior to the knee [1]. This vein is considered the second largest blood vessel in the leg. Like most of the superficial leg veins, this vein features smooth muscle cells in its adventitia and the inner media [2]. Also SSV is in danger of becoming distended or having thrombosis [2].

The Respiratory and Cardiovascular systems work together in order to complete specific roles in the body. The Respiratory System is composed of specific organs responsible for inhaling oxygen and gas exchange throughout the lungs and body tissues. The Cardiovascular System is a circulatory system that is powered by the hardest working organ in the body ,the heart, it is responsible for moving nutrients, oxygen, cellular waste products ,and hormones. “Oxygen is required for cellular functions”, (Lysis 1). The cardiovascular and respiratory system work together to assure that all organ tissues sustain sufficient oxygen.

The blood flow of the heart starts at the superior and inferior vena cava. The superior vena cava carries deoxygenated blood from the upper body into the right atrium, while the inferior vena cava carries deoxygenated blood from the lower body into the right atrium. As blood is pooled inside the right atrium, it will passively flow through the tricuspid valve into the right ventricle. The tricuspid valve is simply a one-way valve that prevents backflow of blood.

Although humans have discovered these useful tools, only God can create a fully functional body and only He can create blood. Blood is a connective tissue with many functions. First, blood is a transport medium that allows substances like oxygen, nutrients, hormones, carbon dioxide, and waste products to flow throughout the body. Second, it is a regulatory tissue that monitors the blood’s delicate pH and temperature.

The objective of this experiment is check how heart chambers, vessels and valves of the heart help the heart to achieve its function of pumping blood all over the body. In addition, this experiment would help us understand the double circulation of blood and reasons why it is vital for mammalian organisms. Due to the complexity of mammalian organisms, the exchanges of substances such as oxygen, nutrients and hormones cannot rely on diffusion itself (Kent, 2013). The transportation
