Circulatory System

The heart belongs to the circulatory system. The circulatory system consists of the heart, blood, and blood vessels. The functions of the circulatory system are: Transport gases, like oxygen from the lungs to cells around the body and carbon dioxide from the cells to the lungs., Transport nutrients like glucose., Transport wastes from cells to organs that play the role of eliminating them., Contain cells that fight infections and defend against foreign bodies., Maintain the pH levels and ionic concentration of fluids in the body., Help maintain the body temperature- this is especially important in warm blooded animals like humans.

Blood that flows from the lungs to the heart is oxygenated, so it's bright red. In contrast, blood that flows from the heart to the lungs is deoxygenated, and so is dark red.

grasshoppers, have an open circulatory system

U must be from jkhs like me!!! William Harvey

The circulatory system can be considered as composed of two parts: The main components of the human circulatory system are the heart, the blood, by tissues undergoing high metabolism, as they require increased levels of oxygen.

Cardiac Output = stroke volume x heart rate

Therefore, 70cm3 x 70 b/min = 4900 cm/min

Oxygenated blood is pumped from the (left side of the) heart through the arteries and so is under a relatively high degree of pressure from there which contributes to its "speed." Additionally, arteries have a good mix of muscular and elastic tissue which also help propel blood along. Deoxgenated blood travels back to the heart through veins. Veins have larger lumens and lack the degree of muscular and elastic tissue that arteries have. They are also are too far from the heart to benefit from the pumping action from it AND they have to work against gravity. As a result, veins depend on muscle contractions in your lower limbs to squeeze the blood upward towards the heart. As you might imagine this isn't nearly as fast as a heart that pumps blood forward 60 to 80 times a minute and so deoxygenated venous blood moves much slower that oxygenated arterial blood.

Yes

Surface area to volume ratio

The human body stays balanced by oxygen and nuteints to the blood cells

Simply because of how hard it is to get oxygen to all the cells in your body. If you were a single celled organism, oxygen could simply dissolve across your cell membrane. However since you are made up of thousands upon thousands of cells, this is no longer an option. Instead the oxygen needs to be delivered to each cell by a circulatory system, and because you are so big this system needs to be complex so that it works effectively.

what do zebras circulatory system have?

The type of circulation liquid being carried out is bloos

the person that gave this answer is Melissa Monique maldanaldo

To provide an interface between an access network and a DSLAM

Yes, it is. The external jugular passes over (superficially) to the sternocleidomastoid.

The reason why is because YOU NEED TO QUIT THE BULL CRAP AND FIGURE IT OUT FOR YOURSELF DUMB A$%

The right atrium receives "de-oxygenated" blood (blood from the body containing less oxygen and more carbon dioxide) and the right ventricle sends this blood toward the lungs.

False

To circulate hemoglobin to all the organs of the body. This hemoglobin contains oxygen which is essential for the working of the body

vein

In the neck, just forward and below the back edge of the jaw.

The large blood vessel is called the aorta.
