CIRCULATORY SYSTEM

 CHARACTERISTICS: 

They have the lymphatic system, the passage of lymph is much longer that the passage of th blood.

THE BLOOD_ is made of plasma, red cells, white cells, and platelets. That is going to the heart witeh the vascular system that carries all the things of the blood away to the body tissues.

The cardiovascular system comprimes all blood, heart and blood vessels .

The circulatory system have two components systemic and pulmonary circulation.

PARTS:

THE MAIN PARTS ARE : 

 Heart, veins, arteries, capillares, blood vessels, brain and the pulmonary artery.

FUNCTIONS:

The circulatory system is a organ system that bumbs it heart and passes all the nutrients, oxygen, blood cells through the blood.

The function of its passing tubes called veins and arteries are connected also more than one time. A vein is going obiusly to be connected with an artery beetwen a capillary

The 98% of the oxygen in an arterial blood is normal talking about a healthy human breathing in the sea level. The other 2% is phisically dissolved in other blood liquids that are not connected to the primary olecule called hemoglobin that that transports oxygen in mammals and other species.

RELATIONSHIPS:

RESPIRATORY SYSTEM_ When we inspire, we are introducing gases into our lungs, including oxygen. When the inspired air reaches the pulmonary alveoli, oxygen passes to the blood and through the hemoglobin is transported by the arteries to the muscle cells

DIGESTIVE SYSTEM_ is that the substances absorbed by the walls of the small intestine are carried by the blood to the liver and the blood vessels that communicate with the small intestine and other abdominal organs with the liver.

EXCRETORY SYSTEM_ is the expulsion of waste that is formed in the cells of the body. The cell generates it, expels it and when it passes to the circulatory system. Where is responsible for bringing these residues to the excretory organs: lung to eliminate CO2, to the skin, to eliminate sweat.


FUN FACTS:

The heart rate or pulse varies depending on the level of physical activity. That's why we can talk about different types of heart rate.

When performing physical exercise the heart produces a response that is tachycardia (the resting heart rate is above 100 beats per minute). Bradycardia may also occur (heart rate is below 50)
