The human heart consist of four chambers – 2 atria and 2 ventricles.

It doesn’t looks like people usually think about it but it is a bit similar.

The circulatory system consist of cardiovascular system and lymphatic system.

Vessels of the circulatory system are divided into veins and arteries. Veins conduct blood into the heart and arteries conduct blood from the heart. What is more we can say that vessels have different vocabulary connected with them – arteries give off branches and they supply tissues and veins have tributaries and they drain blood from tissue.

In the heart blood flows through: slajd

Functionally we can distinguished: slajd

It causes that the left part of the heart has high-oxygenated blood and the right part of the heart has low-oxygenated blood.

Blood from the heart flows by LV through arteries to capillaries and then it is drained by veins to RA.

Aorta – the main artery in our body has 3 parts: slajd

Aortic arch has 3 branches: slajd

Abdominal aorta has 3 terminal branches – two paired and one unpaired: slajd

From the lower limbs and lower part of the body blood returns by: slajd

Upper

Blood from the heart flows by RV through pulmonary arteries to capillaries in the lungs and then it is drained by pulmonary veins to LA.

Pulmonary trunk leaving out the right ventricle and divide into right and left pulmonary artery

respiratory, cardiovascular, digestive, skeletal-muscular, integumentary, nervous, endocrine, urinary, reproductive, haematopoetic, immune, lymphatic

Pulmonary veins returning blood from the lungs to the heart. There are 4 pulmonary veins which are tributaries of left atrium.
