Circulatory System

nicotine is a dangerous "drug" that damages the respiratory system , specifically the lungs . So, If a person does not smokes , and does not inhale "secondhand smoke" , his/her respiratory system will be healthy...

The circulatory system is the transportation system of your body.

often correct themselves without medical treatments by the age of two. If this dose not happen, surgery is done by sewing the hole closed, or by sewing a patch of Dacron material or a piece of the sac that surrounds the heart. In contemporary time it is repaired without an open heart surgery . catheterization is use where a small catheter is inserted to the heart via the viens from the leg up to the heart . Two kinds are available of the filling material of the hole . One kind is a disc filled with polyster and the other one is an umbrella shaped materail that fills the hole in .

No, some invertebrates lack circulatory systems all together such as cnidarians, psudocoelomates and poriferas (sponges). Most of these use tubes that link their internal body to the external environment or they use a gastrovascular cavity. Some have closed circulatory systems such as mollusks (not cephlapods) and anthropods, the pump a fluid that lacks the complete distinction between extracellular fluid and circulating fluid thus this fluid is called Hemolymph.

The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart, arteries, capillaries and veins. As blood begins to circulate, it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen. This is important for the cells in the brain and the body to do their work. The oxygen rich blood travels throughout the body in its system of arteries into the smallest arterioles. On its way back to the heart, the blood travels through a system of veins. As it reaches the lungs, the carbon dioxide (a waste product) is removed from the blood and replace with fresh oxygen that we have inhaled through the lungs.

The Brachial artery on the inside of the elbow is most commonly used because it can be accessed easily and compressed with a cuff. However it does depend on what method you are using.

With use of sphygmomanometer (inflated cuff compresses artery) you can use the brachial or the radial (at the wrist - the same as commonly used for taking the pulse). This gives less reliable results. (Some monitors even use the digital arteries in the finger).

Invasive methods in which the pressure is measured directly by passing a sensor into directly the artery are often used during surgical or invasive procedures. In such cases larger deeper seated arteries are used (eg Subclavian - behind the collarbone or femoral - in the groin) as well as the brachial or radial arteries.

No. Cows, like humans, only have one circulatory system that is connected by only one heart. The systemic and pulmonary circuits of the circulatory system are such circuits that are interconnected within a mammal's body via the heart.

Two many functions of the circulatory system are the movement of nutrients and oxygen to the tissues, and movement of wastes from the tissues to the excretory system. The main organs are the heart and blood vessels.

The four main components of the circulatory system is the following;

1. Heart

2. Veins

3. Artery

4. Vessels

the lower heart.

Large arteries and veins are like high-capacity highways, and they branch into smaller capillaries which go all through the body, so capillaries are like roads.

the blood in your circulatory system is connected to your brain there for it is also connected to your nerves because most of your body has nerves that will tell your brain is something is wrong.

Nutrients are absorbed throughout the digestive process. Specific nutrients are absorbed in the stomach and large intestines, but the majority of nutrients are absorbed in the small intestines.

This is the best explanation I could gather. Hopefully, this helped you. The respiratory system is responsible for taking in oxygen and eliminating waste gases like carbon dioxide. Because dogs and cats do not sweat through the skin, the respiratory system also plays an important role in the regulation of temperature.

since the body needs more oxygen to use while exercising your blood carries oxygen around your body to meet the sufficient needs of your exercise intensity hence why you breathe more while exercising more as your body needs to get in as much oxygen as possible, this means a higher heart rate as your heart is working and pumping faster to try and keep up with demands

When you are too hot, the thermoregulatory centre in the brain signals the capillaries close to the skin surface to dilate. At the same time, glands in the dermis excrete sweat. Thermal energy in the capillaries heats the sweat, causing it to evaporate. Consequently, heat is lost into the surroundings.

The heart and the lungs play a major role in the circulatory system. The circulatory system also include the arteries, capillaries, and veins.

they have a single loop meaning the blood passes through the heart only once to go to everywhere in the body

the capillary walls are 1/1000 of a centimeter [very thin compared to other blood vessels]

The digestive system breaks down and absorbs food. The circulatory system circulates blood through your body. The respiratory system exchanges oxygen and carbon dioxide. With the help of the circulatory system it transfers these gases to and from your cells.

Yes, directly related. When the heart beats it pushes blood around the body. You can feel a pulse as the blood moves around the body at a variety of places (the neck, the wrist, the top of the leg). The pulse you can feel is from the blood being pushed every second or so - but the heart. The pulse rate is the same as the heartbeat rate.

No they are not the same. The cardiovascular system involves the circulatory system and the lungs and it transports oxygen and removes co2 from the body. On the other hand the circulatory system is responsible for moving blood throughout the body. So while they involve the same parts they are not the same system

There are many ways the heart works with other organs. Heart pumps blood throughout the body, to other organs, which brings them oxygen. Without a fresh supply of oxygenated blood the other organs will die. The heart works with the lungs via the pulmonary circulatory system in order to oxygenate the blood. Deoxygenated blood, high in carbon dioxide waste, is pumped from the right ventricle through the pulmonary artery to the lungs to pick up oxygen and loose carbon dioxide. The blood then returns into the left atrium via the pulmonary vein before being pumped to all other parts of the body.

The digestive system delivers nutrients to your blood, which the circulatory system carries to tissues. But remember, without your nervous system, your body wouldn't be able to function.

The heart pumps hormones from the endocrine system throughout the body, allowing them to reach their target receptors to keep the body in balance.
