The cardiovascular system transports oxygen, nutrients, and waste throughout the body using the heart, blood vessels, and blood. The heart pumps blood through a closed system of arteries, capillaries, and veins. In the lungs, oxygen passes from the alveoli into the blood and is circulated throughout the body by the cardiovascular system before returning to the heart. The cardiovascular system helps distribute substances, regulate pH and temperature, and protects the body from pathogens.
The circulatory system is made up of the heart, blood vessels, and blood. The heart pumps blood through three circuits - coronary, pulmonary, and systemic circulation. It has four chambers: right and left atria receive blood, and right and left ventricles pump blood to the lungs and body. Blood contains plasma and formed elements like red blood cells, white blood cells, and platelets. Arteries carry oxygenated blood away from the heart while veins return deoxygenated blood to the heart. Capillaries allow for exchange of oxygen, nutrients and waste between blood and body tissues.
The circulatory system functions to deliver needed materials to cells, remove waste from cells, and fight off infections. It consists of the heart with four chambers that pump blood through two pathways - the pulmonary circuit which sends blood to the lungs to exchange gases and the systemic circuit which pumps oxygenated blood to the body. Blood vessels including arteries, veins, and capillaries transport blood and allow for the exchange of materials between blood and body cells. The heart beat and pulsing blood flow are controlled to maintain healthy blood pressure levels, while diseases can occur if the circulatory system is compromised.
The circulatory system transports nutrients, oxygen, hormones, blood cells, and removes waste through the cardiovascular and lymphatic systems. Blood circulates through arteries and veins, carrying oxygen to tissues and waste away. Lymph circulates through lymph vessels, returning excess fluid to blood. The cardiovascular system comprises the heart and blood vessels. The heart pumps blood which circulates through two loops - pulmonary circulation to the lungs and systemic circulation to the body. Hemodynamics is the study of blood flow and factors influencing circulation like blood pressure, volume, and vessel resistance.
This document provides an overview of transport in mammals. It begins with lesson objectives related to describing the functions of blood, identifying blood vessels and blood disorders, and outlining the structure and function of the heart. The document then covers various components of the circulatory system including the components of blood (plasma, red blood cells, white blood cells, platelets), blood groups, major blood vessels, and the transfer of materials between capillaries and tissue fluid. It discusses the structure and function of arteries, veins and capillaries. Finally, it mentions describing the structure and function of the heart, outlining the cardiac cycle, and describing coronary heart disease.
The circulatory system document summarizes the key components of the human circulatory system in 3 parts: blood, blood vessels, and heart. It describes how blood consists of plasma and formed elements like red blood cells, white blood cells, and platelets. It outlines the types of blood vessels - arteries, veins, and capillaries. Finally, it provides details on the structure and function of the heart, including the 4 chambers, valves, heartbeat, and how blood is pumped through pulmonary and systemic circulation.
The circulatory system carries blood throughout the body and supplies cells with oxygen and nutrients. It consists of the heart, blood, and blood vessels. The heart pumps blood through arteries, veins, and capillaries at a rate of around 72 beats per minute. The circulatory system transports oxygen from the lungs to cells, nutrients like glucose, and waste from cells to organs for elimination. It also helps maintain body temperature and defend against infection. Common diseases include valve disorders, ischemic heart disease, and cardiac arrhythmias.

1) Mammals require transport systems like the circulatory system to efficiently deliver oxygen and nutrients to cells throughout the body since diffusion is only effective over short distances. The circulatory system can be open, closed, or a double circulatory system.
2) In a closed circulatory system, blood remains within blood vessels and nutrients/gases are exchanged through vessel walls. A double circulatory system has two circuits - pulmonary and systemic - allowing blood to pass through the heart twice.
3) Diseases can occur if cholesterol builds up in artery walls, restricting blood flow and oxygen delivery. This can cause heart attacks, strokes, aneurysms, and high blood pressure. Proper diet, exercise, and managing

The circulatory system transports blood, nutrients, gases, and wastes throughout the body. It consists of the heart, blood vessels, and blood. The heart has four chambers that pump blood through two circuits - pulmonary circulation to the lungs and systemic circulation to the rest of the body. Blood flows through the heart in a double circulation, passing through the heart twice with each complete circuit. The cardiac cycle involves the coordinated contraction and relaxation of the heart's chambers. Blood pressure varies within the heart and arteries over the cardiac cycle and between individuals based on factors like age and activity level.
The circulatory system transports blood through tubes called blood vessels, with the heart pumping blood continuously through this network. The blood vessels form a closed system where oxygenated blood from the lungs is pumped by the left side of the heart to the body and deoxygenated blood returns to the right side of the heart and lungs. The heart has four chambers - two upper atria and two lower ventricles - that are separated by a septum to keep oxygenated and deoxygenated blood separate as they circulate through the body.

The document summarizes the transportation system in human beings. It describes how blood transports oxygen, nutrients, waste and other materials throughout the body using a network of blood vessels and the heart as the pumping organ. Blood is circulated via double circulation, where it passes through the heart twice - first to pick up oxygen in the lungs and then distribute it to tissues before returning to be reoxygenated. The system is maintained by platelets that help form clots to plug leaks in blood vessels. Lymph and tissue fluid also transport nutrients and remove excess fluid from tissues before returning to blood circulation.

The circulatory system is an organ system that permits blood and lymph circulation to transport nutrients, oxygen, carbon dioxide, hormones, blood cells, etc. to and from cells in the body to nourish it and help to fight diseases, stabilize body temperature and pH, and to maintain homeostasis.
This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which returns excess filtered blood plasma from the interstitial fluid (between cells) as lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The more primitive, diploblastic animal phyla lack circulatory systems. The lymphatic system, on the other hand, is an open system providing an accessory route for excess interstitial fluid to get returned to the blood.
The circulatory system transports blood, nutrients, oxygen, hormones, and other materials throughout the body. It consists of the cardiovascular system, which circulates blood, and the lymphatic system, which circulates lymph. Blood is pumped from the heart through arteries and returns to the heart through veins. The lymphatic system returns filtered blood plasma from tissues as lymph. Hemodynamics refers to the study of blood flow and circulation. Key factors that influence blood flow include blood pressure, vessel diameter, blood viscosity, and respiration.
The cardiovascular system consists of the heart and blood vessels. The heart pumps blood through two circuits - the pulmonary circuit which circulates blood to the lungs, and the systemic circuit which pumps blood to the rest of the body. Blood flows through arteries, capillaries where gas exchange occurs, and veins which return blood to the heart. The cardiovascular system works to supply oxygen and nutrients to tissues and remove wastes through complex vascular pathways and pressure gradients established by the heart. Cardiovascular disorders like atherosclerosis and hypertension can develop when this delicate system is damaged or imbalanced.
Chapter 37- Circulatory and Respiratory SystemsMary Beth Smith
The circulatory system transports blood throughout the body via the heart and blood vessels. The heart has four chambers and uses valves to pump oxygenated blood from the lungs and deoxygenated blood to the lungs. Blood flows through arteries, capillaries, and veins.

The Cardiovascular System Essay
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through a network of arteries, veins, and capillaries that extend over 60,000 miles throughout the body, delivering oxygen and nutrients to tissues and removing waste. Blood flows from the heart through arteries, into smaller arterioles and capillaries, then into venules and veins before returning to the heart. The circulatory system allows for the transportation of blood, oxygen, hormones, and other substances essential for life.
The circulatory system transports blood throughout the body via arteries, veins, and capillaries. The heart pumps deoxygenated blood to the lungs and oxygenated blood to the rest of the body in separate circuits. Red blood cells carry oxygen and nutrients to tissues while white blood cells help fight infection. Together, blood flow and gas exchange allow all cells to receive necessary materials and remove waste.
The cardiovascular system consists of the heart and blood vessels. The heart pumps blood through arteries, capillaries, and veins in a closed circulatory system. In the capillaries, nutrients and waste are exchanged. The heart has four chambers and valves that ensure blood flows in one direction through the pulmonary and systemic circuits. It beats regularly due to an intrinsic pacemaker and conduction system. Blood transports oxygen, nutrients, hormones and waste throughout the body in a continuous cycle.
The circulatory system transports oxygen, nutrients, water, and waste throughout the body via blood vessels. It consists of the heart, blood, and a network of arteries, veins, and capillaries. The heart pumps oxygen-rich blood to tissues via the arteries and receives oxygen-poor blood back via the veins to replenish oxygen levels. The circulatory system allows for the exchange of gases, nutrients, hormones, and waste between blood and body cells through capillaries.

The circulatory system transports nutrients, gases, hormones, blood cells, etc. to and from cells in the body. It consists of the heart, blood vessels (arteries, veins, capillaries), and blood. The heart pumps blood through blood vessels to supply oxygen and remove carbon dioxide from tissues throughout the body. Blood contains plasma, red blood cells, white blood cells, and platelets. The circulatory system also helps fight infections and regulates body temperature.
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through two circuits - pulmonary circulation and systemic circulation. In pulmonary circulation, deoxygenated blood leaves the right ventricle and is pumped to the lungs where carbon dioxide is released and oxygen absorbed. Oxygenated blood then returns to the left atrium. In systemic circulation, oxygenated blood leaves the left ventricle and is pumped through arteries to tissues throughout the body, where oxygen is delivered and carbon dioxide and waste are collected and returned to the right atrium via veins.
This document summarizes the structure and function of the cardiovascular system. It describes how arteries, arterioles, capillaries and veins transport blood throughout the body in two circuits - the pulmonary circuit and the systemic circuit. Key components of the heart like the atria, ventricles and valves are identified. The roles of blood pressure, blood flow and cardiac cycle are explained.
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.
The circulatory system is comprised of the heart, blood vessels, and lymph vessels. The heart pumps blood through two circuits - pulmonary circulation carries deoxygenated blood to the lungs and systemic circulation distributes oxygenated blood to the entire body. Blood vessels include arteries, which carry blood away from the heart, capillaries, which enable exchange of nutrients and waste, and veins, which return blood to the heart. The lymphatic system drains excess fluid from tissues and produces immune cells.
2. CARDIOVASCULAR SYSTEM
The cardiovascular system transports substances such as
oxygen and nutrients between tissues and organs. It also
helps to transport and eliminate waste products. The heart,
blood vessels and blood form a sophisticated network that
transports these materials around the body. They are
carried by the blood through the blood vessels and are kept
in motion by the pumping action of the heart.
3. The cells in the body need oxygen and it is the blood that
brings it from the lungs to the various tissues and organs.
When breathing, oxygen passes across the alveolar –
capillary (respiratory) membrane and is picked up by the
blood. Newly oxygenated blood travels along the pulmonary
circuit to the heart, where it is pumped to other parts of the
body via the systemic circuit. Once the blood reaches these
other tissues, the oxygen it contains is released and
exchanged for carbon dioxide. Deoxygenated blood is
returned to the heart where it is pumped back to the lungs to
drop off carbon dioxide and pick up oxygen, completing the
cycle.
4. THE HEART
This small muscle is able to pump approximately 5 to 6 litres of blood per minute,
even when you are at rest. It pumps more than 7,000 litres of blood a day through
an estimated 100,000km of blood vessels. Snugly enclosed within the mediastinum,
the medial cavity of the thorax, the heart extends obliquely from the second rib to
the fifth intercostal space. The human heart is a hollow, muscular pump that is
divided into four chambers. The two top chambers are called atria, and the two
lower chambers the ventricles. The chambers perform different functions. The atria
collect the blood that enters the heart and push it to the ventricles, while the
ventricles push blood out of the heart and into the arteries to go to the rest of the
body. The two atria are separated by an interatrial septum while the interventricular
septum divides the two ventricles.
5. BLOOD FLOW THROUGH THE HEART
In order to move blood through your heart, your heart chambers undergo alternating periods of
relaxation (diastole) and contraction (systole) allowing the chambers to fill up with, and pump
blood, respectively. The regular contraction and relaxation of the heart is controlled by its electrical
system. The heart must beat regularly to deliver oxygen to the body’s cells to keep it functioning
properly. The right atrium of the heart receives deoxygenated blood from two major veins, the
superior vena cava and the inferior vena cava, as well as a smaller coronary sinus that drains
blood from the heart wall. When this chamber contracts blood moves out of the right atrium and
into the right ventricle through the tricuspid valve. Once the right ventricle is sufficiently filled with
blood this chamber contracts; pumping blood via the pulmonary arteries into the pulmonary circuit
of the cardiovascular system. Newly oxygenated blood enters the left atrium of the heart through
the pulmonary veins. Once this chamber is filled with blood the left atrial wall contracts; pushing
blood into the left ventricle through the bicuspid valve. After the left ventricle has filled with blood
this chamber contracts; forcing blood out of the ventricle and into the aorta. From the aorta, blood
travels through the systemic circuit of the blood vessels, bringing oxygen to tissue cells throughout
the body.
6. THE HEART VALVES
The heart valves act as gates that allow blood to pass between heart chambers or from heart
chambers to their associated blood vessels. They include the tricuspid, pulmonary, bicuspid (or mitral)
and aortic valves. The tricuspid valve is located between the atrium and ventricle on the right side of
the heart. When this valve is open, blood passes from the right atrium into the right ventricle. The
tricuspid valve prevents the reverse of blood flow back into the atrium by closing during ventricular
contraction. With the tricuspid valve closed, the only outlet for blood in the right ventricle is through the
pulmonary trunk. The pulmonary trunk splits into the left and right pulmonary arteries which connect to
the left and right lungs, respectively. The entrance to the pulmonary trunk is guarded by the pulmonary
valve. The pulmonary valve is made up of three leaves that open when the right ventricle contracts
and close when this chamber relaxes, allowing blood to flow from the right ventricle into the pulmonary
arteries but not the reverse. The bicuspid or mitral valve regulates the flow of blood from the left atrium
to the left ventricle. Like the tricuspid valve, the bicuspid valve closes during ventricular contraction.
The bicuspid valve is composed of two leaves. The aortic valve consists of three leaves found at the
entrance to the aorta. This valve lets blood out of the left ventricle as it contracts and blocks the
pathway of blood from the aorta back into the left ventricle when this chamber relaxes.
7. BLOOD
The blood transports nearly everything that must be transported within the body. It exits the heart
via arteries which branch repeatedly until they become tiny capillaries. By diffusing across the
capillary walls, oxygen and nutrients leave the blood and enter the body tissues, and carbon
dioxide and wastes move from the tissues to the bloodstream. Blood is a sticky, opaque fluid with
a characteristic metallic taste and is heavier, thicker and about five times more viscous than water.
Depending on the amount of oxygen it is carrying, the colour of blood varies from scarlet (oxygen
rich) to a dark red (oxygen poor). Its temperature is about 380 C, always slightly higher than body
temperature. Blood is pumped through the body at a speed of about 30cm/second, with a
complete circulation time of 20 seconds.
The blood volume of an average-sized male is 5-6 litres; an average-sized female has 4-5 litres.
Blood constitutes about 8% of the total body weight.
8. FUNCTIONS OF THE BLOOD
• distribution - blood transports oxygen from the lungs to the cells of the body and carbon
dioxide from the cells to the lungs;
• it also carries nutrients from the gastrointestinal tract to the cells; heat and waste products
away from the cells, and hormones from endocrine glands to other body cells;
• regulation - blood regulates pH through buffers. It also adjusts body temperature through the
heat-absorbing and coolant properties of its water content and its variable rate of flow through
the skin where excess heat can be lost to the environment. Blood also influences the water
content of cells, principally through dissolved ions and proteins; and
• protection - the clotting mechanism protects against blood loss and certain phagocytic white
blood cells or specialised plasma proteins such as antibodies protect against foreign microbes
and toxins.
9. COMPOSITION OF BLOOD
Blood is a liquid connective tissue composed of:
• 45% of its volume is composed of formed elements (cells and cell fragments); and
•55% is plasma (liquid containing dissolved substances). The formed elements constituting 45% of
the volume consist of:
•erythrocytes (red blood cells);
•leucocytes (white blood cells); and
•thrombocytes (platelets).
10. ERYTHROCYTES (RED BLOOD CELLS)
Red blood cells make up over 99% of your blood cells. Blood gets its red colour from the protein
haemoglobin within the red blood cells. Haemoglobin enables red blood cells to transport oxygen
around the body. Production of erythrocytes takes place in red bone marrow. Erythrocytes are
completely dedicated to their job of respiratory gas exchange (oxygen and carbon dioxide transport).
Most oxygen carried in blood is bound to haemoglobin. The haemoglobin in erythrocytes combines
easily and reversibly with oxygen and with carbon dioxide and transports them through blood vessels.
When haemoglobin combines with oxygen, it forms a bright red compound called oxyhaemoglobin;
when oxygen is released, the compound darkens and becomes deoxyhaemoglobin.
11. LEUCOCYTES (WHITE BLOOD CELLS)
Leucocytes also develop in red bone marrow but are far less numerous than erythrocytes.
Leucocytes are crucial to our defence against disease. They form a mobile army that helps protect
the body from damage by bacteria, viruses, parasites, toxins and tumour cells. They combat these
by engulfing them in a process called phagocytosis (eating).
12. THROMBOCYTES (PLATELETS)
Platelets are fragments of cells that are less than half the size of red blood cells. Platelets help
repair blood vessels by adhering to damaged walls and help to trigger blood coagulation (or
clotting) which prevents bleeding and blood escaping from the blood vessel.
13. PLASMA
Plasma is a straw-coloured liquid consisting of 91.5% water, containing a variety of dissolved
substances. These include plasma proteins, nutrients, gases, electrolytes, hormones, enzymes
and waste products.
14. BLOOD VESSELS
The blood vessels form a closed system of tubes that carry blood away from the heart, transport it
to the tissues of the body then return it to the heart. The three main types of blood vessels are
arteries capillaries and veins.
15. ARTERIES
Arteries are the blood vessels that carry blood away from the heart to the tissues of the body. They
have two major properties, elasticity and contractibility. As the ventricles contract, blood is pushed
into the arteries which expand to accommodate it. As the ventricles relax, the elastic recoil of the
artery walls forces the blood onwards.
16. ARTERIOLES
These are very small (almost microscopic) arteries that deliver blood to the capillaries. Arterioles
plat a key role in regulating blood flow from the arteries into the capillaries. During
vasoconstrictions, blood flow to the capillaries is restricted; during vasodilation, the flow is
significantly increased.
17. CAPILLARIES
Capillaries are the smallest blood vessels that connect from the arterioles to the venules. Their
very thin walls enable the capillaries to be the site of exchange of nutrients and other substances
(such as oxygen and carbon dioxide) between the blood and tissue calls of the body.
18. VENULES
• When several capillaries unite. They form small veins called venules. Venules collect blood
from capillaries and drain it into veins. Venules are similar in structure to arterioles; their walls
are thinner near the capillaries and thicker as they progress toward the heart.
19. VEINS
Veins carry blood towards the heart. By the time blood leaves the capillaries and moves into veins,
it has lost a great deal of pressure.
A simple way to remember: arteries and Arterioles carry blood away from the heart, while veins
and venules bring it back to visit the heart.
20. HEART DISEASES
Cardiovascular disease (CVD) is a collective term for diseases of the heart and blood vessels. The
term commonly includes diseases such as coronary heart disease, heart failure, cardiomyopathy,
congenital heart disease, peripheral vascular disease and stroke
