What are the functions 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.
  • Transports hormones from their sources to the target tissues
  • Transports drugs and medicines to the target organs
  • absorption of the digested food from the alimentary canal (except lipids & fats)

The cardiovascular system is a complex network of the heart, blood vessels and blood. It's job is to deliver nutrients to the body and remove byproducts from the tissues

Heart

What cavity is the heart in?

The heart is in the thoracic cavity in a part called the mediastinum. It is protected by the pericardium, a membranous sac that surround the heart. The mediastinum is that space in the thoracic cavity between the lungs that contains the heart. It also contains the aorta, esophagus, trachea and thymus.
The pleural cavity is the space in the chest between the lungs.

What is serosa in physiology?

It's basically a layer or layers of tissue covering most of the body's "canals" like the stomach, intestine, blood vessels, etc. Some serosa secrete mucus-like substances like in the case of the stomach and intestine which reduces friction when foods are passing in. However, some serosa ang muscular, meaning, they contract, most of the time, involuntarily. Some serosa are also epithelial in nature. These are usually found covering lining the outermost layer.

Does bruising mean poor circulation?

A bruise does not mean that you have poor circulation. Healthy persons can also have it because it is basically caused by trauma or injury. The blood vessel was injured, allowing blood to "escape" the vessel and go towards neighboring tissues.

How do the circulatory and respiratory systems work together?

The circulatory system transports oxygen through the body and the respiratory system supplies that oxygen. The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen. This occurs in the lungs, and the circulatory system then transports the oxygen to tissues that used internal respiration to burn fuel in the form of ATP (adenosine triphosphate) for energy, thus creating more carbon dioxide. The alveoil transport oxygen from the lungs into the circulatory system. You breathe in oxygen into your lungs. The oxygen diffuses across the thin walls of the alveoli in the lungs and the thin walls of the blood vessels in the lungs into the blood stream. Here it attaches to the hemoglobin molecules inside red blood cells. The red blood cells are carried by the blood vessels to all parts of the body. The hemoglobin releases oxygen in the periphery, and picks up carbon dioxide (CO2). The CO2 attached to the hemoglobin molecules in the red blood cells is then transported to the lungs, where it diffuses across the walls into the alveoli, and is breathed out.

Respiratory System - GETS the oxygen needed for cells

Circulatory System - DELIVERS the oxygen to cells
The respiratory system is related to your circulatory system because your respiratory system helps you breathe in oxygen. Your blood is pumped to the lungs to pick up oxygen, then flows back to the heart to be pumped to the rest of your body to meet the needs of your body. I hope that helped! :P

How does the circulatory system work?

As red blood cells begins to circulate, the blood just got the fresh oxygen from the lungs. The oxygenated blood flows down into the left side of the heart. The blood goes through the left atrium, left ventricle, and then leaves the heart going into the arteries starting with the aorta.

The aorta is the largest artery in the body. The red blood cells flows through the whole body through the arteries. The food, water, and oxygen collected in the red blood cells is released and the blood collects carbon dioxide, a waste product. The carbon dioxide rich blood travels throughout the body in its system of arteries into the smallest arterioles. White blood cells flow through the body, but all it does is kill viruses in the bloodstream. The blood leaving the aorta is full of carbon dioxide.

To get back to the heart, a series of events must occur. Flowing from the arteries, the red blood cells flow into the capillaries. Nutrients in the blood is transported to the cells. The rest of the blood goes to the veins. The veins are tubes that run through your body to get the blood back to the heart.

The red blood cells finally reach the right side of the heart. It goes up and down into the right atrium, then to the right ventricle and into the lungs. The red blood cells is now full of carbon dioxide, and when we breath out, the carbon dioxide is carried out into our mouths, out into the atmosphere. When we breath in the oxygen comes into the red blood cells. Now the cycle starts all over again.

They work together by inhaling and exhaling . The heart pumps blood into the lungs where the blood is oxygenated. The blood is then returned to the heart and the newly oxygenated blood is circulated to the rest of the body. The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen. This occurs in the lungs and the circulatory system then transports the oxygen to tissues that used internal respiration to burn fuel in the form of ATP (adenosine triphosphate) for energy, thus creating more carbon dioxide.

You breathe in oxygen into your lungs. The oxygen diffuses across the thin walls of the alveoli in the lungs and the thin walls of the blood vessels in the lungs into the blood stream.

The circulatory bring the oxygen that the lungs take in around the body and bring the carbon dioxide back for the lungs to expel. The lungs bring oxygen into the blood which feeds the heart and the rest of the body!

The respiratory system brings in oxygen, which the circulatory system (i.e. blood) carries around the body and delivers to the muscle tissue. When the oxygen is used up and carbon dioxide is produced, the circulatory system brings the CO2 back to the lungs, where the respiratory system disposes of it.

They work hand in hand to provide the tissues of the body with oxygen. The respiratory system oxygenates the blood and the circulatory system sends it to the rest of the body.
The heart works as a pump basically moving blood through the entire system to nourish the body and deliver oxygen to tissue. The heart pumps blood through the capillary vessels around the lungs so that red blood cells can pick up oxygen that has been transported across the alveolar membranes in the lungs. Maybe that a little over simplified but thats the basic idea.


Your lungs send oxygen to your heart so the blood can have oxygen in it
When you inhale, oxygen rushes into your lungs which is diffused into your bloodstream through alveoli located on the bronchioles. The heart pumps oxygenated blood throughout your body. All cells absorb oxygen which they need to live. Blood becomes deoxygenated and continues to be pumped by heart back to lungs. Deoxygenated blood also contains waste products of cells which are rid from your body when you exhale.
The lungs do not affect how the blood flows through the arteries and veins, it simply provides oxygen to the hemoglobin in the blood so that it may be carried to your organs. The heart is responsible for making sure that blood is flowing through the body's arteries and veins because it pumps it throughout the body.
The lungs pull oxygen into the body. The heart oxygenates the blood cells by pumping the blood to the lungs. Together with the arterial and venous system, the body is oxygenated.
the lungs inhale oxygen which goes to your avioli that lets the Oxygen seep into the blood and takes out the carbon dioxide so your body can function.
The heart pumps oxygen poor blood to the lungs, where the lungs infuse oxygen into the blood, and then the heart distributes the oxygen rich blood throughout the body supplying your muscles with oxygen.
The cardiovascular system works with the respiratory system to ensure that all living cells receive a constant supply of oxygen - the cardiovascular system pumps the oxygen around the body and the respiratory system allows the oxygen to enter the blood from inhaled air.

Allergies

Bladder

Can you be allergic to another person?

Yes you actually can not to him of course but if he uses a certain cologne or soap you might be allergic to it or you could possibly have sensitive skin which causes the sweat glands to get inflamed and cause a rash look on the skin surface

I have the very same problem with my husband. Because we use the same products on our faces, it must not be a reaction to those types of things. I do notice that the length of the beard makes a significant difference in the amount of irritation I experience. 2-3 days growth, is the worst. A full and soft beard doesn't seem to irritate my skin at all. Otherwise, my only remedy from the bumps and severe itching is cotizone cream. Hope that helps!
