Circulatory System

Left atrium, then this goes to the left ventricle, then to the aorta and the rest of the body.

Yes, temp. regulation is a function of the Cardiovascular system but also the Integumentary system. The blood distributes heat created by muscle contraction to the rest of the body. Blood vessels in the skin dilate when body temperature rises and constrict when heat needs to be conserved. In this way, the integumentary system plays a key role in regulating body temperature.

§ The heart beats around 3 billion times in the averages person's life.

§ About 8 million blood cells die in the human body every second, and the same numbers are born each second.

§ Within a tiny droplet of blood, there are some 5 million red blood cells.

§ It takes about 20 seconds for a red blood cell to circle the whole body.

§ Red blood cells make approximately 250,000 round trips of the body before returning to the bone marrow, where they were born, to die.

§ One of the amazing facts of circulatory system is that the heart continues to beat even when it's taken out of the body.

§ Human blood is colorless, it is the hemoglobin that makes it red.

§ The body of an adult contains over 60,000 miles of blood vessels!

§ An adult's heart pumps nearly 4000 gallons of blood each day!

There are 3 phases in the cardiac cycle: 1) Ventricular filling: mid-to-late diastole; 2) Ventricular systole; and 3) Isovolumetric relaxation: early diastole. In phase two, ventricular systole, the atria relax and the ventricles begin contracting. Their walls close in on the blood in their chambers, and ventricular pressure rises closing the atriaventricular (AV) valve. Because, for a split second, the ventricles are completely closed chambers and blood volume in the chambers remain constant, it is called the isovolumetric contraction phase.

Haemophilia is an hereditary disease that affects the coagulation factors, they suffer mutations and don't work properly. This leaves the person vulnerable to hemorrhage, injuries take a lot longer to heal and may suffer of spontaneous bleeding (be it a simple nosebleed or severe gastrointestinal bleeding). Chronic hemorrahges cause anemia and iron deficit, and the loss of blood volume lowers the arterial pressure and causes tachycardia. In the worst case, a person can bleed to death with realtively minor injuries.

Very true

The process that would likely occur in an open circulatory system would be that food would travel from one end to the other without much absorption. With an open circulatory system, fluid is used to take in food and excrete waste.

Gas Exchange· When you think about how the cardiovascular system works with other body systems, you probably think of the respiratory system. This is because the circulatory system has a direct path through the lungs. When blood returns from the body to the heart, it is depleted of oxygen. It has to pick up oxygen in the lungs before it can return to circulation.

The deoxygenated blood first enters the right atrium of the heart then fills the right ventricle. From the right ventricle it is pumped to the lungs via the pulmonary artery. The pulmonary artery passes the blood through the lungs via capillaries surrounding thin membrane sacs called alveoli. The blood and alveoli exchange oxygen and carbon dioxide.

The newly oxygenated blood travels back into the heart by way of the pulmonary veins. The pulmonary veins deliver the blood into the left atrium, which empties into the left ventricle. The left ventricle pumps the blood into circulation throughout the rest of the body.

The digestive system passes nutrients into the blood for distribution around the body. The kidneys remove wastes from the blood. The endocrine system uses the circulatory system to distribute hormones.

When sleeping the body's circulatory system begins to slow down. It is easier for the blood to circulate throughout the body.

this is it summarised hope it helps: The respiratory system oxygenates blood, which is part of the cardiovascular system. The CV system supplies oxygenated blood to the part that make up all three systems, allowing respiration to occur and the cells, tissues and organs to work. The digestive system absorbs glucose into the blood, to provide energy for respiration to the cells of all tissues. This allows breathing, peristalsis and the pumping of the heart to occur.

Shortness of breath, pain in the left chest, left arm pain.

yes

The digestive system of annelids consists of an unsegmented gut that runs through the middle of the body from the mouth, located on the underside of the head, to the anus, which is on the pygidium.

A catchy phrase for the muscular system should be memorable as well as conveying the message you want to be remembered. An example is 'Muscles: Long and Strong.'

125.000 kilometers (about 10 times around the earth)

Pulmonary and systemic circulation

Cholesterol is what builds up in your heart valve's. It blocks blood flow and causes strokes and heart attacks because blood doesn't give to other important organs like your brain and kidney's.

There is only one major organ in circulatory system that is heart.

Brain and lungs are not its parts they are parts of nervous and resperatory system.

you may also see blood vessels as a part of circulatory system but its not an organ.

Unlike the mammals,the snake's resp system contains a long right lung & a small left lung.The longer lung covers almost two third of the body.The shorter one is the rudimentary one. The utility of such a long lung is well understandable in snakes that,while negotiating a swalloed prey item,there might long period of air hunger.when vital oxygination of cells could take place from residual lung air. Amazingly snakes could tolerate very low conc of oxygen to survive.

The three major parts of the circulatory system are the heart, the blood, and the blood vessels.

The circulatory system is used to transport blood throughout the body. More specifically, blood contains several specific types of cells: platelets, red blood cells, white blood cells, and nutrients. Platelets block up external wounds to prevent bleeding. Red blood cells transfer nutrients throughout the body, and white blood cells protect the body from external germs, such as disease.
