starting from the Veins
Vein (unoxygenated) (e.g Inferior Vena cava) > right atrium > right ventricle > Pulmonary truck > Pulmonary Arterys > Lungs (to become oxygenated) > Pulmonary Veins (now oxygenated) > left Atrium > left ventricle > aorta > to the arteries in the body > arterioles > capillaries > venules > veins (where the oxygen is again replaced by coz and is thus unoxygenated)
(the cycle repeats itself)
starts at brain ends at heart you have the upper which is the bigger and the lower which is the smaller
The heart. Specifically through the Vena Cava.
Blood returning from the head in mammals will pass through the superior vena cava just before entering the right atrium.
The Superior Aorta Is A Vein, Also Known As The Superior Vena Cavae Which Allows Dirty, De- Oxygenated Blood To Enter The Heart That Has Passed Through Other Organs.
Blood entering the right atrium is blood returning from the upper and lower body and it has been to the cells and given up all its oxygen
venae cavae
The vena cavae collect blood from the systemic circulation. They deliver this deoxygenated blood to the right atrium.
-tricuspid valve -pulmonary semilunar valve -mitral/bicuspid valve -aotic valve
Vena cavae
Venae cavae are the largest two.Aorta
The main vein in the body is the Vena Cavae vein. The inferior vena cavae vein carries blood from the legs and stomach to the heart. The superior vena cavae carries blood from the arms and head to the right atrium of the heart.
No, veins take deoxygenated blood back to the heart through the superior and inferior vena cavae.
summary of cuerts during blood circulation
The right atrium of the heart receives low-oxygen blood from the body through the superior and inferior vena cavae.
Venae cavae are the largest two.Aorta
The right atrium pumps the blood it receives from the body (through the superior and inferior vena cavae and the coronary sinus) to the right ventricle which then sends it to the lungs.
The right ventricle receives blood from the right atrium, and the right atrium receives blood from the pulmonary veins.This blood was already drained from the whole body to the vena cavae. So its from veins in the body to venae cavae, from venae cavae to pulmonary veins, from pulmonary veins to the right atrium, from the right atrium then to the right ventricle.
