You may be thinking of William Harvey, who was the first to describe the circulatory system in some detail.
William Harvey
All the cells in the human body naturally produce waste products due to normal cellular processes, these waste products could accumulate in the blood and body if they were not removed through filtration.
8 pints of blood10 litres of blood on average in an adult and 7 or lower in a child
The blood travels around the human body through blood vestals slowly or fast depending on what your heart beat is like.Blood from heart goes to artery, then arteriole, then to capillary, which goes venule, then to the vein, then the blood goes back to the heart.
about one minute
The human heart is composed of four chambers. They are the right atrium, right ventricle, left atrium and left ventricle. The heart also contains four valves that ensure that blood flows continuously through the heart in the correct direction. Oxygen depleted blood is channeled from the body into the heart through the Inferior and Superior vena cava. It first enters the right atrium then passes through the tricuspid valve into the right ventricle. From there the blood is forced through the pulmonary valve into the pulmonary arteries and on to the lungs where it dumps carbon dioxide and picks up oxygen.The newly oxygenated blood is returned from the lungs to the heart via the pulmonary veins. It enters the left atrium, is forced through the bicuspid valve and into the left ventricle. From there the blood passes through the aortic valve into the aorta (the body's largest artery) which branches into several smaller arteries as it circulates the freshly oxygenated throughout the body
William Harvey
It circulates blood throughout the body.
On average, the blood in an adult's body circulates about 1,200 times in one minute. This rate may vary depending on factors such as heart rate and physical activity.
Via the circulatory system which consist of veins, arteries and capillaries which aid in the transportation of all blood to and from the heart muscle.
what a ? humman body blood circulation is 3-7 liter blood per minute.
Mammalian heart including man is two pumps in one consisting of four chambers. Humans have an efficient double circuit circulation i.e., pulmonary and systemic.
actually, it's possible to live without a heart, but you must have it replaced by another thing that circulates your blood.
Not really, because as humans are warmblooded mammals, when the blood circulates around the body it passes through the heart and back again (like a figure 8 around the body) as it comes back through the lungs it becomes oxygenated. (I hope that makes sense!!)
He proved He was God through rising from the dead without any human help.He overcame the curse of sin through His death AND resurrection.He proved there is a heaven, a place after death.He proved that He could overcome death and provided hope for us.He proved His ultimate power over earth.
Human circulatory system is a double circulatory system (two times) because blood passes through the heart twice in a complete circuit. (for oxygenated blood and deoxygenated blood) There are two types of circulatory system in human beings : 1.pulmonary circulatory- blood circulates from the heart to the lungs and back to the heart 2.systematic circulation- blood circulatea from the heart to other organs and back to the heart. The human heart will undergo over 3 billion contraction cycles
The human organ system that circulates blood is called the circulatory system or the cardiovascular system. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. This system transports oxygen, nutrients, hormones, and other substances throughout the body, as well as removes waste products.
