What else can I help you with?
Where do white blood cells occur in the human body?
Throughout the Circulatory System. They are part of the Immune System. They are manufactured by the lymphaticsystem.
What process would likely occur in an open circulatory system?
The process that would likely occur in an open circulatory system would be that food would travel from one end to the other without much absorption. With an open circulatory system, fluid is used to take in food and excrete waste.
How does circulation occur in Mammals?
circulation of the blood occurs in mammals b/c of the heart. it pumps the blood through out the body, which is circulation. the heart is an organ of the circulatory system
If the circulatory system isn't working what diseases may occur?
If your circulatory system is not working, you do not need to worry about diseases because you will be dead.
In which part of the circulatory system does the greatest pressure drop occur?
The greatest pressure drop in the circulatory system occurs in the arterioles. Arterioles are small, muscular blood vessels that regulate blood flow and control blood pressure. As blood travels from the arteries to the capillaries, the arterioles cause a significant decrease in pressure to ensure proper exchange of nutrients and waste between the blood and tissues.
What is the difference between a closed and an open circulatory system?
In an open circulatory system, a tubular heart pumps hemolymph into a hemocoel (a system of interconnected sinuses), where chemical exchange can occur with the "bathed" tissues. The hemolymph diffuses back to the heart. This creates a sluggish blood flow because of low pressure & low oxygen content, resulting in low efficiency. In a closed circulatory system, a muscular heart pumps blood into large vessels that branch into smaller vessels that course through the organs. The blood is confined to vessels and are distinct from the interstitial fluid. Basically, an open circulatory system is somehow connected to the environment, while the closed circulatory system is just confined in the animal's body.
Where does oxygenation occur?
Oxygen exchanges occur in the lungs where the circulatory system takes in oxygen and releases carbon dioxide into the lungs. Oxygen exchanges also occur in the capillaries where the circulatory system delivers oxygen to the cells and picks up carbon dioxide from the cells.
Why does the respiratory and circulatory work so closely together?
When you breathe in air it goes in your lungs and the oxygen diffuses into the blood stream via the capillaries. Then the oxygen is carried throughout your body as needed.
When does cerebral embolism occur?
Cerebral embolism occurs when a blood clot from elsewhere in the circulatory system breaks free. If it becomes lodged in an artery supplying the brain, either in the brain or in the neck, it can cause a stroke.
Where does oxygen transfer during the transition between the respiratory and circulatory system occur?
By diffusion across a capillary wall.
What are the names of the cycles that occur in the body?
lymphatic system, blood circulation system
What structure is known as the functional unit of the cardiovascular system?
The capillary is known as the functional unit of the cardiovascular system. Capillaries are small blood vessels where gas exchange and nutrient exchange occur between the blood and tissues. This exchange is essential for delivering oxygen and nutrients to cells and removing waste products.
