The heart is a muscular organ located in the chest behind the ribs. It has four chambers that pump blood throughout the body. The two upper chambers are atria which receive blood, and the two lower chambers are ventricles which pump blood out. The left ventricle pumps oxygen-rich blood to the body while the right ventricle pumps oxygen-poor blood to the lungs. Diseases associated with the heart include hypertensive heart disease, cerebrovascular disease, and ischemic heart disease. Cerebrovascular disease occurs when arteries to the brain are narrowed by plaque, restricting blood flow and oxygen, and can cause strokes. Symptoms include headaches and vision or speech problems. It is diagnosed using imaging tests and treated with

The Heart Science 7th class powerpoint presentation
The document summarizes the key parts and functions of the human heart and circulatory system. It discusses how the heart is a non-stop muscular pump with four chambers that pushes oxygenated blood through arteries and returns deoxygenated blood through veins. The left side of the heart is larger and more powerful as it pumps blood through the entire body, while the right side pumps blood to the lungs to receive oxygen before returning to the left side. With each heartbeat, the heart vigorously contracts ("lub") to push blood out and relaxes ("dub") to refill in its continuous cycle to circulate blood throughout the entire body.
Anatomy of heart copy - copy
The heart is a muscular organ that pumps blood through the circulatory system. It is divided into four chambers - the left and right atria receive blood, and the left and right ventricles pump blood out. The heart contracts and relaxes in a cardiac cycle, with the ventricles relaxing to fill with blood during diastole and contracting to pump blood during systole. The heart pumps deoxygenated blood to the lungs and oxygenated blood throughout the body to supply organs and tissues with nutrients and oxygen.

The document describes the structure and function of the heart. It notes that the heart is a hollow muscular organ that pumps blood through the blood vessels to the body. It then lists and describes the 15 main parts of the heart, including the atria, ventricles, valves, veins and arteries. The parts work together to oxygenate blood and pump it throughout the body.
Human heart
The human heart has four chambers - two atria that receive blood and two ventricles that pump blood. The right side receives deoxygenated blood from the body and pumps it to the lungs, while the left side receives oxygenated blood from the lungs and pumps it to the body. The heart is made of cardiac muscle that can contract regularly without fatigue. Blood returns to the heart through the vena cavae and pulmonary veins and is pumped back out through the pulmonary artery and aorta.
Blood Flow
The document summarizes the human circulatory system. It describes how unoxygenated blood enters the right atrium of the heart from the body, passes to the right ventricle, and is then pumped via the pulmonary arteries to the lungs where it receives oxygen. The oxygenated blood returns to the left atrium via the pulmonary veins and is then pumped by the left ventricle through the aorta to the body tissues, where oxygen is delivered and carbon dioxide picked up, before returning again to the right atrium to restart the cycle. The blood also transports nutrients, wastes, hormones and antibodies around the body simultaneously.
Human Heart
The heart is a pumping organ located in the chest that continuously circulates blood through the body. It has four chambers - the two upper chambers are the atria and the two lower chambers are the ventricles. The septum separates the chambers and prevents mixing of oxygenated and deoxygenated blood. Blood flows from the right atrium to the right ventricle then to the lungs, returns oxygenated to the left atrium and left ventricle, then is pumped through the aorta to the rest of the body in a continuous cycle.

Anatomy Of Cardiovasvular System
Cardiovascular system
This document summarizes the main components of the cardiovascular system, including the heart, blood vessels (arteries, veins, and capillaries), and blood. It describes the heart's location and layers (epicardium, myocardium, endocardium). The heart chambers are the atria and ventricles, separated by septa. The document lists the four heart valves - tricuspid, bicuspid, pulmonic, and aortic - and their locations. It provides a brief overview of the pulmonary and systemic circulations, describing how deoxygenated blood flows from the heart to the lungs to become oxygenated before returning to the heart.
The Human Heart
The heart is a muscular organ roughly the size of a fist located behind the breastbone. It pumps blood through the cardiovascular system. The heart has four chambers - two upper atria and two lower ventricles. The right side receives deoxygenated blood from the body and pumps it to the lungs, while the left side receives oxygenated blood from the lungs and pumps it back out to the body. Valves between the chambers prevent backflow of blood. When the heart contracts, these valves open and close in sequence to ensure blood flows in one direction through the entire circulatory system.
Cardiovascular system.
The circulatory system consists of the heart and blood vessels that circulate blood throughout the body. The cardiovascular system transports blood, nutrients, oxygen, wastes, and more. It includes the heart, arteries, veins, and capillaries. Blood flows from the heart through arteries, then to capillaries where nutrients and oxygen are exchanged, then returns to the heart through veins. Blood pressure is the force of blood pushing against artery walls and normal blood pressure is below 120/80 mmHg. Factors like diet, exercise, and medical conditions can impact blood pressure levels.
THE HEART PPT
The heart is located slightly left of center in the chest and is about the size of a fist. It pumps blood through arteries and veins called blood vessels throughout the body. The blood carries oxygen, nutrients, and chemicals to tissues and removes waste. Coronary heart disease, cardiovascular disease, and heart failure can occur if the heart does not circulate blood properly. Maintaining a healthy lifestyle through diet and exercise can help prevent heart disease.
Heart Presentation
The human heart has four chambers - the right atrium, left atrium, right ventricle, and left ventricle. The arteries carry oxygenated blood away from the heart while the veins carry deoxygenated blood to the heart. The aorta is the largest artery and carries oxygenated blood from the left ventricle to the rest of the body. Pulmonary veins uniquely carry oxygenated blood from the lungs to the left atrium.
Human Heart and its function
The circulatory system is made up of the heart and blood vessels. The heart is a muscular organ about the size of a fist located slightly left of the breastbone. It pumps blood through blood vessels including arteries, veins, and capillaries. The heart has four chambers - two upper chambers called atria that receive blood and two lower chambers called ventricles that pump blood out of the heart. It contracts in a cardiac cycle where the atria and ventricles contract simultaneously to circulate blood throughout the body.
Structure of the Heart
The heart has a double circulatory system where blood travels through the right and left sides of the heart twice before returning to the body. The septum separates the right and left sides. Deoxygenated blood enters the right atrium via the superior and inferior vena cava and is pumped to the right ventricle and then to the lungs via the pulmonary artery. Oxygenated blood returns from the lungs to the left atrium through the pulmonary veins and is pumped from the left ventricle to the body through the aorta. Valves prevent backflow of blood through the heart.

Human heart(1)
The human heart is located slightly left of center in the chest and is about the size of a fist. It has four chambers - two upper auricles that receive blood and two lower ventricles that pump blood out. The right side receives deoxygenated blood and pumps it to the lungs while the left side receives oxygenated blood from the lungs and pumps it out to the body via the aorta, the largest artery. There are two types of valves in the heart - atrioventricular valves that prevent backflow between chambers and semilunar valves that prevent backflow in the ventricles. The heart is a muscular pump that circulates blood through the body using these chambers and valves.
The Parts of the Heart
The document describes several components of the cardiovascular system:
- Arteries transport oxygenated blood from the heart to tissues throughout the body, with the aorta being the largest artery connected to the left ventricle.
- The pulmonary artery is unique in that it carries deoxygenated blood from the heart to the lungs.
- Veins return deoxygenated blood to the heart, with the vena cava being the largest vein.
- The four chambers of the heart - left atrium, left ventricle, right atrium, and right ventricle - work to circulate oxygenated and deoxygenated blood.
How the heart works
Our heart is roughly the size of a clenched fist and is located in the middle of your chest between tow lungs, tilted more to the left. This small, fist-sized organ is one of the most critical organs.
The heart
The heart is divided into four chambers that receive and pump blood throughout the body. The two upper chambers, called atria, receive blood returning to the heart while the two lower chambers, called ventricles, pump blood out to the body and lungs. The heart wall contains three layers and uses electrical signals to coordinate contractions that pump blood in two phases of the cardiac cycle. Valves allow blood to flow in only one direction through the heart and into the major arteries and veins.
Science 9 Circulatory System
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps oxygenated blood received from the lungs through the left side and deoxygenated blood through the right side to the lungs. It has four main valves - the mitral, aortic, tricuspid, and pulmonary valves - that ensure blood flows in one direction. The circulatory system delivers oxygen and nutrients throughout the body and removes waste via a network of arteries, veins, and capillaries. It is essential for sustaining life.

It notes that blood is composed of erythrocytes, leukocytes, platelets, and plasma. Blood circulates through arteries, capillaries, and veins via the pumping action of the heart. The four chambers of the heart work together with four valves to oxygenate blood in the lungs and circulate it throughout the body in the pulmonary and systemic circuits.
Heart Anatomy Shaikh Sameer Pharm D I year.pdf
The heart has four chambers divided into left and right sides separated by septums. The two upper chambers are the atria and the two lower chambers are the ventricles. Blood flows from the atria to the ventricles through valves and is pumped from the right ventricle to the lungs and from the left ventricle to the body. The heart receives its own blood supply from the coronary arteries which branch from the aorta.
Blood circulatory system
The circulatory system, consisting of the heart, blood vessels and blood, circulates blood throughout the body to supply nutrients and oxygen to tissues and remove waste. The heart pumps blood in two circuits - pulmonary circulation between the heart and lungs, and systemic circulation between the heart and the rest of the body. Blood contains red blood cells, white blood cells, platelets and plasma in a fluid connective tissue that transports substances to tissues and removes waste. Common diseases of the circulatory system include high blood pressure.
Assignment on Circulation of blood
IT WILL BE HELPFUL FOR IRREGULAR STUDENTS LIKE ME. YOU MAY COPY AND PASTE IT.
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.
Case study pregnancy induced hypertension
Pregnancy Induced Hypertension (PIH) is a condition characterized by high blood pressure, protein in the urine, and swelling during pregnancy. The exact cause is unknown, though it is more common in certain at-risk groups. PIH is classified based on symptoms from gestational hypertension with just high blood pressure to preeclampsia with additional symptoms to eclampsia which is the most severe form with seizures. Women at high risk should be monitored closely for symptoms during prenatal visits.

Bees anatomy
Bees have several organ systems including a circulatory, digestive, and glandular system. Their circulatory system involves an open circulatory system where hemolymph freely circulates nutrients. The digestive system includes a crop for storing nectar and a ventriculus for digesting food. The glandular system produces and secretes products both internally and externally. Bees live in hives which can house over 80,000 bees ruled by a queen. They collect pollen and nectar as food and use it to create honey which they store in the hive. While bees can sting if threatened, their stings often kill them since their stingers get left behind.
liver noor alessa
The liver is a large reddish-brown organ located on the upper-right side of the stomach that performs many essential functions such as removing toxins from the body, producing proteins and bile to aid digestion, storing glucose, and purifying blood. Diseases of the liver include cirrhosis, hepatitis, fatty liver disease, and chronic liver disease. Cirrhosis occurs when scar tissue replaces healthy liver tissue over time due to various causes such as viruses, toxins, fatty liver disease, or autoimmune disease, eventually leading the liver to malfunction. Symptoms of cirrhosis include loss of appetite, itching, weakness, and yellowing of the skin. While lifestyle changes and medications can help treat cirrhosis
Kidneys by Rana Al Hajraf
The kidneys are two bean-shaped organs located below the rib cage that filter waste from the blood and regulate fluid levels. They remove waste from the body through urine production. Common kidney diseases include kidney failure, stones, and urinary tract infections (UTIs). UTIs occur when bacteria like E. coli enter the urethra and travel up to the bladder and kidneys, causing infection. Symptoms include burning urine and abdominal pain. Diagnosis involves urine testing and treatment uses antibiotics to kill the bacteria.
Brain anatomy prj
The brain is the most complex organ located in the skull. It controls the entire body and is made up of fat, protein, and several parts including the right and left hemispheres. The brain can develop diseases like Alzheimer's, tumors, and cancers. Brain cancer occurs when cells in the brain grow uncontrollably, potentially causing headaches, seizures, and other neurological issues. Treatment may involve surgery, radiation, and chemotherapy depending on the cancer's size, type, and location in the brain.
The bladder monirah al khudari
The bladder is a hollow, muscular sac located in the pelvis that stores urine before it leaves the body. Urine passes from the kidneys to the bladder through ureters and is expelled through the urethra. Common bladder issues include urinary stones, cancer, overactive bladder, and retention. Bladder cancer occurs when cells grow uncontrollably to form tumors and spreads rapidly; risk factors include genetics, race, and family history. Diagnosis involves medical history, exams, and tests, while treatments range from surgery to laser removal depending on the patient's condition.

Heart anatomy mona al mailam
- 1. Heart Done By: Mona Al Mailam
- 2. What is the organ? The heart is one of the main organs in the body. The heart is made up of many strong muscles that squeeze and relax to pump blood to all parts of the body. The blood flowing contains oxygen, food, vitamins, and minerals your body needs to function. This pump happens about 70-90 times per minute. The heart is made up of 4 parts:the left ventricle, the right ventricle which are both at the bottom part of the heart, and the left atrium and the right atrium are located at the top.
- 3. Where is the Heart Located? The heart is located behind your ribs on the left side of your body next to your sternum.
- 4. The various functions of each part of the heart : 1. Aorta the body's largest artery. Takes oxygenated blood from the left ventricle to the body. 2. Pulmonary Artery carries deoxygenated blood from the right ventricle to the lungs. 3. Oxygenated blood carrying oxygen 4. Deoxygenated blood carrying little or oxygen 5. Right Atrium Receives deoxygenated blood from the body 6. Pulmonary Vein Takes oxygenated blood from the lungs to the left atrium 7. Left Ventricle Pumps oxygenated blood into the aorta 8. Right Ventricle pumps deoxygenated blood into the pulmonary artery 9. Coronary Vessels supply the heart muscle with its blood supply 10. Arteries carry blood away from the heart 11. Veins carry blood towards the heart 12. Bicuspid Valve valve between the left atrium and the left ventricle. 13. Tricuspid Valve valve between the right atrium an the right ventricle. 14. Vena Cava the largest vein in the body, it carries blood from the body back to the heart.
- 5. Diseases associated with the heart: 1. Hypertensive heart disease 2. Cerebrovascular disease 3. Ischemic heart disease 4. Rheumatic heart disease 5. Inflammatory heart disease
- 7. Causes : Is when a build up of a thick waxy substance in the vessel that narrows or blocks the blood flow in the arteries That is caused by high cholesterol levels.
- 8. Symptoms: headache that is severe and sudden •confusion •difficulty communicating •loss of half of vision •loss of balance •loss of consciousness
- 9. Diagnoses: ● computes tomography ● magnetic resonance imaging (MRI) ● cerebral angiography- identify responsible blood vessel ● electrocardiogram (ECG)-underlying heart conditions ● echocardiogranm- blood clot from heart ● carotid duplex- carotid artery stenosis.
- 10. Treatment: In the case of a minor stroke, a medication called tissue plasminogen activator (tPA) may be given which breaks the clot. If it is a larger stroke a surgery may be required.
