What do the numbers 120 over 80 refer to?
blood pressure or BP, 120 refers to the amount of pressure produced when the ventricles of the heart contract and 80 refers to the pressure in the blood vessels (normally measured via the brachial artery in the humerus) when the heart is at resting. 120/80 is known as the ideal blood pressure.
What is Cerebrospinal fluid produced by in the ventricles?
Cerebrospinal Fluid or CSF is produced by the ventricles in your brain.It protects and flows through your brain and the spinal cord. It acts as a cushion for them.
The four chambers within the brain where cerebrospinal fluid is produced are called?
The four chambers within the brain where cerebrospinal fluid is produced are called the ventricles. The lateral ventricles are located in each cerebral hemisphere, while the third ventricle is in the diencephalon, and the fourth ventricle is between the brainstem and the cerebellum.
Why do heart beats sound like 2 quick beats?
The beats are caused by the valves in the heart closing. The first beat occurs when the ventricles contract. The pressure in them increases, so the atrioventricular valves close. The second beat occurs when the ventricles relax. As the pressure decreases, blood is sucked back from the aorta and pulmonary artery causing the semi lunar valves to close.
When the valves between atria and ventricles closed what sound is produced?
When the Aalves close between the Ventricles and the Artery what sounfd does it make.
What does systolic stands for?
Systolic comes from the Greek word, "systole", which means to draw together or contract. Systolic pressure is the maximum pressure produced in the arteries when the left ventricle of the heart contracts.
What is produced by the ventricles and baths the brain and spinal cord?
Cerebral spinal fluid, or CSF.
Why is the lubb sound the loudest when auschlated?
The "lubb" sound, or S1 heart sound, is the loudest during auscultation because it is produced by the closure of the atrioventricular (AV) valves (mitral and tricuspid) at the beginning of ventricular contraction (systole). This closure creates a significant pressure change and turbulence in the blood flow, resulting in a more pronounced sound. Additionally, the ventricles generate high pressure as they contract, further amplifying the sound as it is transmitted through the heart and surrounding tissues.
Most CSF id produced within what ventricle?
Most cerebrospinal fluid (CSF) is produced within the lateral ventricles of the brain.
What is CSF and how is it related to the ventricles in the brain?
Cerebrospinal fluid (CSF) is a clear, colorless fluid that surrounds and protects the brain and spinal cord. It is produced in the ventricles of the brain and circulates through them, providing nutrients and removing waste products. The ventricles are interconnected cavities within the brain where CSF is produced and stored before flowing throughout the central nervous system.
What are the parts of the ventricular system?
The ventricular system consists of four interconnected cavities in the brain called the lateral ventricles (one in each hemisphere), the third ventricle, and the fourth ventricle. Cerebrospinal fluid is produced in the ventricles and circulated around the brain and spinal cord to provide cushioning and protection.
Why is lub dubb produce?
The "lub-dub" sound of the heartbeat is produced by the closing of the heart valves. The "lub" (first heart sound) occurs when the atrioventricular valves close as the ventricles contract, while the "dub" (second heart sound) happens when the semilunar valves close as the ventricles relax. This cyclical opening and closing of the valves during the cardiac cycle generates the characteristic sounds associated with a heartbeat.
