The heart is a four-chambered muscular organ covered by a double membrane called the pericardium, with the right atrium and right ventricle pumping deoxygenated blood to the lungs via the pulmonary artery and the left atrium and left ventricle pumping oxygenated blood from the lungs via the pulmonary vein to the rest of the body. Valves between the atria and ventricles regulate blood flow, with the tricuspid valve between the right atrium and right ventricle and the bicuspid valve between the left atrium and left ventricle.

Sructure of heart
The heart is a four-chambered muscular organ covered by a double membrane called the pericardium. It contains a right atrium and ventricle and left atrium and ventricle, separated by the tricuspid and bicuspid (mitral) valves respectively. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs while the pulmonary veins bring oxygenated blood from the lungs to the left atrium.
07 general circulation
The document describes the major blood vessels and circulation pathways in the human body. It discusses the systemic circulation, where oxygenated blood leaves the heart through the aorta and returns to the heart through veins. It also describes the pulmonary circulation between the heart and lungs for gas exchange, as well as the portal circulation between the digestive organs and liver. Key blood vessels discussed include the aorta, vena cava, pulmonary and coronary arteries/veins, and the portal vein.
Fetal circulation
The fetal circulation allows the developing fetus to exchange materials with its mother through structures like the umbilical cord and placenta. There are three major shunts in the fetal circulatory system - the ductus venosus, ductus arteriosus, and foramen ovale - that direct highly-oxygenated blood from the placenta away from the lungs and toward vital organs like the brain and heart. At birth, the loss of placental blood flow and beginning of breathing cause pressure changes and closure of the shunts, redirecting blood flow to the lungs for oxygenation and establishing the postnatal circulatory pattern.
Heart
The document discusses the structure and function of the human heart. It describes the heart as a hollow, cone shaped organ divided into four chambers - the right and left atriums and ventricles. The heart contracts and relaxes in a cycle known as the heartbeat to pump blood through the body. The blood flows through specific paths - from the lungs to the left atrium and ventricle before being pumped through the aorta to the body, then back to the right atrium and ventricle to be pumped to the lungs again. The circulatory system is divided into the pulmonary and systemic circuits which oxygenate blood in the lungs and transport it to and from the body.
Foetal circulation (1)
The fetal circulation allows oxygenated blood from the placenta to bypass the lungs and circulate throughout the fetus's body. Key structures include the umbilical vein, which carries oxygenated blood from the placenta to the liver, the foramen ovale and ductus arteriosus which allow blood to bypass the lungs, and the umbilical arteries which return deoxygenated blood to the placenta. The circulatory process involves blood passing from the placenta through the umbilical vein, mixing with deoxygenated blood and passing through the foramen ovale and ductus arteriosus to supply the fetus before returning to the placenta through the umbilical arteries.
1-fetal circulation
The document summarizes fetal circulation and how it differs from circulation after birth. In the fetus, oxygenated blood flows from the placenta to the umbilical vein and into the liver and heart. Most blood shunts past the lungs through openings like the foramen ovale and ductus arteriosus. After birth, clamping the umbilical cord and lung inflation cause structures like the ductus venosus to close as the infant transition to getting oxygen from the lungs.
Pulmonary & systemic circulation
Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where it becomes oxygenated, and then back to the left side of the heart. Systemic circulation then transports the oxygenated blood from the left ventricle through the arteries and returns it to the right atrium via the veins, except for some blood in the hepatic portal vein which passes through the liver first before returning to the heart. Humans have a double circulatory system with one circuit for pulmonary circulation and one for systemic circulation which together circulate blood throughout the body.

Fetal circulation
1. In fetal circulation, three shunts (ductus venosus, foramen ovale, ductus arteriosus) redirect blood away from the underdeveloped lungs and liver. The placenta provides gas/nutrient exchange.
2. At birth, cutting the umbilical cord closes the placental circulation. The shunts then close as well - the ductus arteriosus and foramen ovale close due to pressure changes upon lung inflation, while the ductus venosus obliterates.
3. Normal postnatal circulation is established with gas exchange in the lungs and nutrient processing by the liver. The umbilical vessels become ligaments.

The heart has four chambers divided by a septum. It pumps blood through two circuits - pulmonary and systemic. Each heartbeat consists of three phases: atrial systole where the auricles contract and push blood into the ventricles, ventricular systole where the ventricles contract and pump blood out, and joint diastole where all chambers relax simultaneously. The heart beats 60-72 times per minute in adults with each cycle lasting around 1 second total.
Pulmonary & systemic circulation
The document summarizes pulmonary circulation and systemic circulation in the human body. It explains that humans have a two-circuit circulatory system, with one circuit for pulmonary circulation transporting deoxygenated blood from the heart to the lungs, and another for systemic circulation transporting oxygenated blood from the heart to the rest of the body. Pulmonary circulation transports deoxygenated blood from the vena cavae to the lungs for oxygenation, then back to the left side of the heart. Systemic circulation then carries the oxygenated blood from the left ventricle through the aorta and arteries to tissues throughout the body, and returns deoxygenated blood back to the right atrium through the vena cava
Fetal circulation
1. The Monroe-Kellie doctrine states that the volume of intracranial contents (brain, blood, CSF) must remain constant since the skull is a rigid container. An increase in one component must be compensated by a decrease in another to avoid rises in intracranial pressure.
2. Arterial blood pressure is regulated in the short term by the autonomic nervous system and baroreceptors, which detect changes in pressure and modulate heart rate and vascular tone. Long term regulation involves the renin-angiotensin-aldosterone system and vasopressin.
3. The cardiac cycle involves repeated cycles
Cardiovascular System
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.
Rji -fetal_circulation
This document summarizes fetal circulation and the transition to postnatal circulation. In the fetus, oxygenated blood from the placenta travels through the umbilical vein to the heart and is shunted away from the lungs through the foramen ovale and ductus arteriosus. After birth, the foramen ovale and ductus arteriosus normally close within the first year as the lungs begin functioning, establishing the postnatal circulatory pattern. Patent ductus arteriosus and patent foramen ovale are common congenital heart defects where these structures fail to close, allowing mixing of oxygenated and deoxygenated blood.
Fetal circulation by dr.srikanta biswas
The fetal circulation differs from the adult circulation due to the presence of three major vascular shunts that allow blood to bypass the lungs. The placenta functions as the fetus's lungs, exchanging oxygen and nutrients between the mother's and fetus's blood without mixing. At birth, changes in lung function and vascular resistance cause the shunts to close as circulation transitions to the adult pattern with blood flowing to the lungs.
Pulmonary Circulation
This document discusses the pulmonary circulation system. It begins by describing how the pulmonary vessels develop in utero to shunt blood away from the lungs, and how after birth the vessels dilate to increase blood flow to the lungs. It then covers the anatomy of the pulmonary system including vessel structure. Pressures throughout the pulmonary system are detailed, including how fluid moves between vessels and tissue. Factors that regulate blood flow to match ventilation are explained. Finally, the causes and safety factors regarding pulmonary edema are summarized.
Coronary,Splanchnic,pulomonary, systemic & Cerebral Circulation
The document summarizes several types of circulatory systems in the body:
- The coronary circulation supplies blood directly to the heart muscle through the right and left coronary arteries.
- The splanchnic circulation provides blood flow to the abdominal organs through branches of the abdominal aorta.
- The systemic circulation pumps oxygenated blood from the left side of the heart to tissues throughout the body, while the pulmonary circulation pumps deoxygenated blood from the right side to the lungs and back to the left side.
- The cerebral circulation supplies blood to the brain through four main arteries that form the circle of Willis at the brain's base.
Physical characteristics of systemic circulation
The document discusses various physical characteristics of the systemic circulation including cross-sectional area, pressure, resistance, blood flow, and vascular compliance and distensibility. It provides details on blood pressure, pulse pressure, factors affecting venous return, vascular resistance according to Ohm's law, and the distensibility and compliance of arteries and veins.
Blood supply and venous drainage of heart
The document summarizes the blood supply and venous drainage of the heart. It discusses that the heart receives its blood supply from the right and left coronary arteries. It then describes the branches of each coronary artery and their territories in detail. It further explains the venous drainage of the heart, which is mainly through the coronary sinus and its tributaries into the right atrium. The document also briefly discusses clinical considerations like coronary artery disease and angina pectoris.
Coronary circulation
The coronary circulation supplies blood to the heart muscle. There are two main coronary arteries - the left and right coronary arteries - that originate from the aorta and branch throughout the heart muscle. The left coronary artery supplies the left side of the heart while the right coronary artery supplies the right side. These arteries branch into smaller arterioles and capillaries to deliver oxygenated blood before draining into coronary veins that remove deoxygenated blood, mostly through the coronary sinus, and return it to the right atrium.
Fetal circulation
The document describes the fetal circulation and changes that occur at birth. In the fetus, oxygenated blood from the placenta travels to the heart and body while bypassing the lungs. At birth, the onset of breathing causes pulmonary vascular resistance to decrease and systemic resistance to increase. This results in blood shunting to the lungs, closure of the ductus arteriosus, and closure of the foramen ovale. The umbilical vessels also close, completing the transition to extrauterine life.
Coronary circulation
The coronary circulation supplies blood to the heart muscle. It consists of an arterial supply from the right and left coronary arteries, which branch off the aorta. The right coronary artery supplies the right atrium and ventricle as well as parts of the left ventricle and septum. The left coronary artery supplies the left atrium and ventricle as well as parts of the right ventricle and septum. Venous drainage occurs through the coronary sinus and smaller cardiac veins that drain directly into the atria or cavities of the heart. Obstructions of the coronary arteries can cause myocardial infarction and angina pectoris, while coronary angioplasty techniques are used to treat arterial narrowing and blockages.

Pulmonary circulation
The pulmonary circulation involves the movement of blood from the heart to the lungs and back to the heart. Deoxygenated blood enters the right atrium from the body and is pumped to the right ventricle and then into the pulmonary artery to the lungs. In the lungs, the blood releases carbon dioxide and picks up oxygen. It then returns via the pulmonary veins to the left atrium and is pumped by the left ventricle back out to the body. The purpose is to oxygenate the blood through gas exchange that only occurs in the lungs.
blood supply of lungs
The document discusses the blood supply of the lungs, which includes the bronchial circulation and pulmonary circulation.
The bronchial circulation supplies oxygenated blood to the bronchi and lungs from the systemic circulation. The pulmonary circulation supplies deoxygenated blood from the right ventricle to the lungs where gas exchange occurs in the pulmonary capillaries before oxygenated blood returns to the left atrium.
The document provides details on the development, anatomy, pressures, and functions of both the bronchial and pulmonary circulations in fetal, neonatal and adult stages. It also discusses factors that regulate pulmonary vascular resistance and the role of the pulmonary circulation in gas exchange, filtering blood, and acting as a reservoir for the left vent
Foetairculation
The fetal circulation differs from adult circulation in that the lungs are not used - the fetus receives oxygen and nutrients from the mother via the placenta and umbilical cord. Blood travels through the umbilical vein to the liver and heart, where most passes through the foramen ovale into the left side of the heart. It is then pumped through the aorta to the body before returning to the placenta and umbilical arteries. At birth, closure of the foramen ovale and ductus arteriosus prevents blood from bypassing the lungs, allowing oxygenated blood from the newborn's first breaths.
