Its All About The Heart By: Jaren, Nick, Tanner, Aaron

Physical Appearance and Location

It looks like a big, red, gushy jellybean.


It is located at the center of the cardiovascular system.



Another organ in the circulatory system

· Veins are another organ in the circulatory system. The main function of veins is to carry blood from the body back to the heart. This blood is low in oxygen, depleted of nutrients, and loaded with waste products. If arteries are the supply train, veins can be thought of as the garbage trucks.

5 facts about the heart

· The average adult heart beats 72 times a minute; 100,000 times a day; 3,600,000 times a year; and 2.5 billion times during a lifetime.


· Though weighing only 11 ounces on average, a healthy heart pumps 2,000 gallons of blood through 60,000 miles of blood vessels each day.

·

A kitchen faucet would need to be turned on all the way for at least 45 years to equal the amount of blood pumped by the heart in an average lifetime.

·

The volume of blood pumped by the heart can vary over a wide range, from five to 30 liters per minute.


Every day, the heart creates enough energy to drive a truck 20 miles. In a lifetime, that is equivalent to driving to the moon and back

5 facts about the circulatory system

The reason that blood is red is because of the red blood cells it contains. These red blood cells, however, are red because of the hemoglobin which is a red colored, iron containing protien that functions in oxygen transport by reversibly binding to oxygen.


The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (polmonary), and arteries, viens, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gasses, and as well as hormones to and from the cells.


An average human has 5-6 quarts (4.7- 5.6 liters) of blood which is made up of plasma, red blood cells, white blood cells, and platelets.


The systemic circulatory is a major portion of the circulatory system. The networkof viens, arteries and blood vessels transports oxygenated blood from the heart, delivers oxygen and nutrients to the body's cells and then returns deoxygenated blood back to the heart.


The system of blood vessels in the human body measure about 60,000 miles (96,560 kiliometers).


Function of 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.
  • It contains cells that fight infections and defend against foreign bodies.
  • Maintains the pH levels and ionic concentration of fluids in the body.
  • Helps maintain the body temperature, this is especially important in warm blooded animals like humans

The importance of the heart

The heart pumps blood all around your body and it picks up oxygen from the lungs to send to numerous cells throughout your body. The oxygen is carried in your blood by red blood cells. Without it, you wouldn't be alive.

Appendix removal

You do not need to have your appendix to live, however you do need your heart to live. You can remove your appendix and move around with no problem, so you should remove the appendix instead of the heart.

interdependence with the circulatory system

The circulatory system relies on the respiratory system because it gets the oxygen that it pumps in the blood from the lungs, and the respiratory system relies on the circulatory system because if the heart couldn't pump the blood it would for nowhere to go and it would stay in the respiratory system.
