The Circulatory System

By Kara Deskin

What Makes Up the Circulatory System

The overall purposes of the circulatory system are to provide nutrients and oxygen to the bodies vital tissues and organs, and to remove waste and fight infections.
The heart pumps oxygenated blood to tissues and organs throughout the body. The blood vessels have two circuits; pulmonary and systemic circulation. In pulmonary circulation the heart pumps the deoxygenated blood to the lungs where it is oxygenated and returned back to the heart. In systemic circulation the oxygenated blood is carried to vital organs and tissues and then returns back to the heart. The lymphatic system is a network of lymphatic vessels which help the body fight infection. The lymph nodes are apart of this system. The lungs circulate the blood from the heart and then send it back to the heart to distribute oxygen and blood to the body.

The lymph nodes

Like I said in the passage above, the lymph nodes are part of the lymphatic system. The main functions of these lymph nodes are to carry tissue liquids to the bloodstream, to absorb digested fats, and lastly concentrations of the lymphoids are found in the thymus and spleen. The lymph nodes contain tissues like the capsule, paracortex, and medula. These tissues form different layers of the lymph nodes. The different types of cells in the lymph are t cells and b cells. T cells are influenced by thymus, and b cells develop in bursa fabricius. These cells are also motile and fixed cells.

Diseases associated with the Circulatory System

Common diseases that associate with the Circulatory System include heart disease, varicose veins, hypertension, and high blood pressure. If you have a heart disease than it would be best to prevent from smoking, make sure to eat and drink healthy, and keep calm and do not stress. Some causes of this disease are bad diets or just not taking care of yourself. Some symptoms that you should watch out for are angina (or chest pain) and heart attacks. You can heal a heart disease with the right medication or surgery. To improve having varicose veins, avoid bad sitting or standing positions. If you have hypertension, prevent from eating salt and do not smoke. Lastly, high blood pressure is cured with a low sodium diet, exercise, and a low stress level.

Can you live without any organ from your Circulatory System? and medical advances

It is still possible to live if some of your arteries or veins are missing. If a missing artery or vein stops your blood flow, than you might die. Doctors have also created artificial hearts if your heart does not function properly. Some medical advances for the Circulatory System would include pace makers, prosthetic valves, and scientists can also open up arteries with a balloon.

Interactions with other body systems

The Circulatory System interacts with the Digestive System because both of these systems work together to distribute nutrients throughout the body. The Respiratory System also works with the Circulatory because these systems work together to send oxygen throughout the body. The Urinary System also cleans the Circulatory System
