The circulatory system consists of the heart, blood, and blood vessels. The heart pumps blood continuously through arteries, veins, and capillaries. Arteries carry oxygen-rich blood from the heart to tissues, while veins return oxygen-poor blood back to the heart. Capillaries allow for the exchange of oxygen, food, waste, and carbon dioxide between blood and cells. Heart rate increases during exercise and fever to pump more blood and regulate body temperature.

Cardiovascular system
The cardiorespiratory system is made up of the circulatory system, heart, blood, and blood vessels. The heart pumps oxygen-rich blood to all parts of the body through the arteries and oxygen-poor blood is returned to the heart through the veins. Gas exchange occurs in the capillaries where oxygen is delivered to cells and carbon dioxide is removed from cells. The circulatory system functions to transport nutrients, oxygen, wastes and more throughout the body.
Cardiovascular System
The cardiovascular system circulates blood throughout the body via the heart and blood vessels. The heart has four chambers and pumps around 4,000 gallons of blood per day through arteries, veins, and capillaries to deliver oxygen and nutrients to cells and remove carbon dioxide and waste. Blood contains plasma, red blood cells to carry oxygen and carbon dioxide, white blood cells to fight infection, and platelets to help clotting.
Circulatory system
The circulatory system transports fuel, wastes, hormones, and disease fighters throughout the body. It includes the heart, which pumps blood through arteries, veins, and capillaries. Blood pressure is measured by the force against blood vessel walls, with normal ranges being 110-140 over 70-90. The circulatory system also transports blood components like plasma, red and white blood cells, and platelets. Maintaining a balanced diet, exercising, avoiding smoking, and managing stress can help the circulatory system, while problems can include leukemia, hemophilia, and arteriosclerosis.
Circulatory System Vocabulary
The document defines key terms related to the circulatory system:
Vessels transport blood throughout the body, including large vessels and small vessels. Red blood cells carry oxygen to cells and carbon dioxide away from cells using the protein hemoglobin. The heart has four chambers - two atriums which receive blood and two ventricles which pump blood to the body and lungs. Veins return deoxygenated blood to the heart while arteries carry oxygenated blood away from the heart to tissues. Capillaries transport blood between arteries and veins, exchanging gases at the cellular level. Circulation refers to the circular path of blood flow through the body and lungs via the heart.
Circulatory system
The circulatory system uses the heart, arteries, veins and capillaries to transport blood throughout the body. The blood carries oxygen from the lungs to tissues and removes carbon dioxide from tissues to the lungs. In the tissues, oxygen diffuses from capillaries into cells and carbon dioxide diffuses into capillaries from cells. The circulatory and respiratory systems work together so that oxygen enters the blood in the lungs while carbon dioxide leaves the blood. The circulatory and digestive systems also work together, with capillaries in the intestines allowing nutrient absorption into the bloodstream.

Bloodbloodvessels
The document summarizes the components and function of blood and blood vessels. It describes that arteries carry oxygen-rich blood away from the heart to capillaries, which connect to veins to return deoxygenated blood back to the heart. The inner walls of arteries are smooth to allow blood flow, while artery walls are muscular to aid pumping. Capillaries are thin and where gas exchange occurs. Veins are less strong than arteries as they transport lower-pressure blood. Blood carries oxygen, nutrients, hormones, antibodies and waste, helps regulate temperature, and forms clots to stop bleeding. Its components are plasma, red and white blood cells, and platelets.
Unit 5: Circulatory system

Oxygen-rich blood is carried from the heart to body cells via arteries and returns to the heart via veins as oxygen-poor blood. The heart pumps blood in two separate circuits - the pulmonary circulation transports blood to the lungs to receive oxygen and the systemic circulation transports oxygenated blood to all body tissues before returning to the heart.
Blood circulatory system & gastroinstential system
The circulatory system consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps oxygen-rich blood to the body and oxygen-poor blood to the lungs. In the capillaries, gases and nutrients are exchanged. The gastrointestinal system converts food into molecules that are distributed and excretes waste. It consists of the mouth, esophagus, stomach, small and large intestines, liver, pancreas, and glands. Food is broken down and absorbed in the small intestine and undigested material passes to the large intestine for water absorption before excretion.

L1 the circulatory system +heart
1. The circulatory system includes the heart and blood vessels that circulate blood throughout the body.
2. The heart acts as a pump to circulate oxygen-rich blood from the lungs and oxygen-poor blood to the lungs through a complex network of arteries, veins, and capillaries.
3. Blood flows through one-way vessels - arteries carry oxygenated blood away from the heart while veins return deoxygenated blood to the heart.
Blood3
The document discusses the human circulatory system. Blood carries oxygen and nutrients throughout the body via blood vessels in a process called circulation. The heart, located between the lungs, pumps blood through three main types of blood vessels - arteries, veins, and capillaries. The respiratory system, including the lungs and airways, provides oxygen to the blood and removes carbon dioxide through breathing movements of inhalation and exhalation.
The heart
The heart is about the size of a fist and located in the center of the chest behind the breastbone. It is made of cardiac muscle and has a pacemaker that signals it to work continuously. The heart has two circuits - in one circuit the blood flows from the heart to the body and back to deliver oxygen and nutrients and remove waste. In the second circuit the blood flows from the heart to the lungs and back so the blood can become oxygenated. The heart is divided into four chambers by a thick wall so that oxygenated and deoxygenated blood are kept separate as they circulate to the body and lungs respectively.
The circulatory system
The circulatory system transports blood throughout the body using the heart and blood vessels. The heart pumps oxygenated blood received from the lungs through arteries into capillaries where oxygen is delivered to cells and carbon dioxide is picked up, before returning to the heart via veins to repeat the cycle. Blood contains plasma, red blood cells, white blood cells and platelets and flows through two circuits - pulmonary circulation from the heart to the lungs and systemic circulation from the heart to the rest of the body.
Heart
The heart is a muscular organ that pumps blood through two separate circulatory loops to transport oxygenated and deoxygenated blood without mixing. It has four chambers - the left and right atria which collect blood, and the left and right ventricles which pump blood out. The heart works by contracting its chambers in a precise sequence to draw in blood, pump it out, and ensure the lungs and body are continuously supplied with blood. Heart disease occurs when this process is disrupted due to issues like clogged arteries, weak pumping, or irregular heart rhythms, and can cause symptoms such as chest pain, trouble breathing, and swelling. Risk factors include high blood pressure, cholesterol, diabetes, obesity, and smoking.

It describes that arteries carry oxygen-rich blood away from the heart to capillaries, which connect to veins to return deoxygenated blood back to the heart. The inner walls of arteries are smooth to allow blood flow, while artery walls are muscular to aid pumping. Capillaries are thin and where gas exchange occurs. Veins are less strong than arteries since they transport blood at lower pressure back to the lungs and heart. Blood carries oxygen, nutrients, hormones, antibodies and waste, and helps regulate temperature and clotting. It has plasma, red blood cells to carry oxygen, white blood cells for immunity, and platelets for clotting

Circulatory system
- 2. Parts of The Circulatory System • Heart • Blood • Blood Vessels
- 3. Heart • It is a the size of our fist • It is near the middle of our chest, slightly to the left • Pumps blood all the time
- 4. Blood • Transports digested food, oxygen, water and carbon dioxide
- 5. Blood Vessels • Tubes where blood flow
- 6. Three types of Blood Vessels • Arteries • Veins • Capillaries
- 7. Arteries • Carry oxygen-rich blood from the heart to other parts of the body • Red in colour
- 8. Veins • Carry oxygen-poor blood from all the parts of our body to our heart • Blue in colour
- 9. Capillaries • Help blood to exchange materials with the cells of our body • -Oxygen, digested food and water pass from the blood through the capillary walls and into the cells • -Carbon Dioxide and waste materials produced by the cells pass through the capillary walls and into the blood
- 10. Heart Rate • Our heart rate will increase when we are exercising as our heart need to pump blood to produce more energy. • Our heart rate will also increase when we are having fever as our body temperature rises when we are having fever, so, it needs to be controlled to prevent overheating. To do so, our hearts beats faster in order to bring more blood to the capillaries in our skin so that heat can be released to the surrounding air to cool our body down.
