Circulatory System

Increased diameter of the arterioles decreases rather increases blood pressure. The heart rate also lowers as the heart does not have to pump blood as hard to get it to flow through the wider the arterioles.

Basically, they are linked to each other. The circulatory system gets oxygen from the lungs, while the respiratory system gets blood from the circulatory system necessary to feed its cells.

The pulmonary circulatory system is part of the cardiovascular system in which oxygen-depleted blood is pumped away from the heart, through the pulmonary artery, to the lungs and returned, oxygenated, to the heart through the pulmonary vein.

Oxygen deprived blood from the superior and inferior vena cava, enters the right atrium of the heart and flows through the tricuspid valve (right atrioventricular valve) into the right ventricle, from which it is then pumped through the pulmonary semilunar valve into the pulmonary artery to the lungs. Gas exchange occurs in the lungs, whereby CO2 is released from the blood, and oxygen is absorbed. The pulmonary vein returns the now oxygen-rich blood to the left atrium.

Consisting of the heart, blood vessels, and blood, this system circulates blood throughout the body, delivers nutrients and other essential materials to cells, and removes waste products.

Clotting in an unbroken blood vessel is known as thrombosis. This occurs when a blood clot (thrombus) forms within a blood vessel, potentially obstructing blood flow. Thrombosis can lead to serious complications, such as deep vein thrombosis or pulmonary embolism, depending on the location of the clot. It can be triggered by factors like injury to the vessel wall, slow blood flow, or abnormalities in blood composition.

The absence of the respiratory system would affect the circulatory system - blood could not be oxygenated; consequently the tissues of the body cannot be supplied with oxygen. This means that the tissues and organs cannot perform their functions and would die due to lack of oxygen. Furthermore, deoxygenated blood would accumulate; so carbon dioxide levels would increase. This decreases the pH (increases acidity) of the blood and the lungs are responsible for regulating this.

Right Atrium

The pumping organ of the circulatory system is the heart. It generates the pressure to move blood through the circulation.

A strong and healthy cardiovascular system keeps blood flowing freely throughout the body and lowers the risk of high blood pressure or heart attack.

Strong Blood Flow:-

A healthy cardiovascular system consists of strong blood vessels that pump blood throughout the body.

Low Blood Pressure:-

A healthy cardiovascular system is vital for maintaining blood pressure levels.

Healthy Heart:-

A benefit of a strong cardiovascular system is a healthy heart. The heart's health is vitally important to the function of the entire body.

Arteries and veins carry freshly-oxygenated blood away from the lungs.

If oxygenated blood from the lungs to the heart is not pumped to the rest of the body, by the heart, then tissues will die from lack of oxygen (and other nutrients transported in the bloodstream). Blood needs to reach all tissues and cells, and can only do so if it propelled to them by a pressure gradient (the pressure being highest in the large arteries, and gradually less until reaching the capillaries, where the pressure is very very low).

Histamine

I believe that every drop of blood passes through your heart to be sanitized and sent to through the rest of your body. I am not sure what else it does though.

Primary hemostasis is the overall sequence of events that leads to the formation of a platelet plug, while Secondary hemostasis is the signal transduction pathway that leads to the formation of fibrin. Secondary Hemostasis is always a part of Primary hemostasis, but involves many clotting factors and other signaling molecules that are specific to the formation of fibrin

the two main organs in our body are the heart and the lungs and the jobs they do are the heart is part of a circulatory system which means it basically pumps blood around the body and the lungs help us breath by bringing oxygen into our body and spreading it around

An embolus is a piece of solid matter circulating in the bloodsteam. If it becomes stationary and obstructs, it is a thrombus.

False.

The cells that hold digestive juices are called the gastric chief cells. These are located in the stomach that secretes enzymes for protein breakdown.

Come again, please? An archaebacterium is a unicellular prokaryote. It doesn't even have a nucleus, let alone any organ systems!

It depends on the level of the paralysis and they type of paralysis. A spinal cord severance below the waist will cause loss of leg feeling and control of the bladder and digestive system. The higher you go the more loss of feeling and less controls you have. If you loose feeling below the neck you can lose the ability to draw in breath and release breath. If you are paralyzed due to stroke you can use lose of muscles or dexterity in your hands or feet. You can lose feeling too. You can lose a lot of function of your facial movements and the ability to swallow. Some stroke patients can regain use of their limbs and facial muscles with hare rehabilitation.

The largest and main artery of the circulatory system is the aorta. It drains the left ventricle.

no, it is part of the nervous

Because idf the circulatory system is altered then another part of the body is not getting all the nutrients that it is necessary for existence.
