This includes the generalized and more specialized functions of transport of materials capillary exchange maintaining health by transporting white blood cells and various immunoglobulins antibodies hemostasis regulation of body temperature and helping to maintain acid-base balance. The right atrium receives deoxygenated blood through the superior and inferior vena cavas from the body and pumps it to the right ventricle through the tricuspid valve which opens to allow the blood flow through and closes to prevent blood backing up the atrium.

The left atrium receives oxygenated blood through the pulmonary veins from the lungs.

Circulatory system pathway of blood flow. Humans and other mammals have two-circuit circulatory systems. 1 body 2 inferiorsuperior vena cava 3 right atrium 4 tricuspid valve 5 right ventricle 6 pulmonary arteries 7 lungs 8 pulmonary veins 9 left atrium 10 mitral or bicuspid valve 11 left ventricle 12 aortic valve 13 aorta 14 body. Heart is a muscular organ that continuously beats throughout the lifetime.

Blood circulation begins when the heart relaxes between heart beats. Blood then flows from both upper atriums left atrium and right atrium into the two lower chambers left and right ventricles which then expand. Blood vessels that take blood away from the heart are arteries.

The pump for the pulmonary circuit which circulates blood through the lungs is the right ventricle. Human Circulatory system The circulatory system is a closed system that transports blood around the body and works coincide with the respiratory system. The pulmonary circuit is the path of circulation between the heart and the lungs.

Blood is then ejected ejection phase when the ventricles contract and pump the blood into the arteries. It consists of the heart and blood vessels. Virtually every cell tissue organ and system in the body is impacted by the circulatory system.

It is located in the middle of the chest and slightly towards the left. One circuit is for pulmonary circulation circulation to the lungs. The blood carries around oxygen nutrient carbon dioxide waste etc.

It carries hormones throughout the body. Blood vessels that take blood towards the heart are veins. Arteries divide into smaller arteries as they go away from the heart.

Lastly the circulatory system helps maintain. The pumping of the heart drives this blood flow through the arteries capillaries and veins. It carries gas throughout the body.

As each atrium and ventricle contract blood is pumped into certain major blood vessels and from there continues through the circulatory system. Pulmonary circuit and systemic circuit. The left ventricle is the pump for the systemic circuit which provides the blood supply for the tissue cells of the body.

Structure of the cardiovascular system. Blood leaves the SVC and the IVC and enters the right atrium RA 3. The blood vessels of the body are functionally divided into two distinctive circuits.

The SVC collects blood from the upper half of the body. The contraction of the heart is termed as systole whereas the relaxation of the heart is termed as diastole. The smaller arteries that connect to the capillaries are called arterioles.

All blood enters the right side of the heart through two veins. In summary from the video in 14 steps blood flows through the heart in the following order. In this video I discuss the circulatory system or cardiovascular system the functions of the cardiovascular system and the path of blood flow through the he.

The circulatory system is the body system that moves blood around the body. Heart works under the control of nervous system to pump blood into the circulatory system. Pulmo lungs and the other circuit is for systemic circulation the rest of the body.

It carries oxygen from the air we breathe to cells throughout the body. Blood is pumped to the various places of the body by a process known as the cardiac cycle. The superior vena cava SVC and the inferior vena cava IVC see figure 3.

The IVC collects blood from the lower half of the body. The circulatory system consists of the heart and the arteries and veins that convey blood throughout the body. This Demonstration shows the steps in the pathway that blood takes while circulating through the heart lungs and body.

Blood must always circulate to sustain life. The Path of blood through the Circulatory System. The pathway of blood circulation is broken into two different circulatory pathways states the National Cancer Institute.

The pulmonary circuit transports de-oxygenated blood from the right ventricle into the lungs to become oxygenated while the systemic circuit carries oxygenated blood to the rest of the body. Blood is pumped from the left ventricle of the heart through the aorta and arterial branches to the arterioles and through capillaries where it reaches an equilibrium with the tissue fluid and then drains through the venules into the veins and returns via the venae cavae to the right atrium of the heart. Adjust the slider to see the path depicted by arrows.

Fights infection and illness. The blood carries various materials that the body needs and takes away waste or harmful substances. If you clench your hand into a fist this is approximately the same size as your heart.

Oxygen depleted blood returns from the body to the right atrium of the heart by two large veins called vena cavae.
