What aids lymph flow?
muscular activitybreathing muscle contraction peristalsis
Is systolic pressure where the ventricls are relaxing?
Relaxation = Diastole Contraction of the atria=Atrial systole Contraction of the ventricles = Ventricular systole
When you take someone's blood pressure you are measuring the pressure during the contraction and relaxation phases of the heart muscle?
true
Why artery called resistance vessels?
The contraction and relaxation of the smooth muscle in their walls can change their diameter, thus changing the level of pressure (large diameter yields low pressure and smaller diameter yields high pressure).
Name two events occuring within the body that aid in venous return?
Muscular contractions, such as those during physical activity, help propel blood back towards the heart by compressing the veins. Additionally, the presence of one-way valves in veins prevents the backflow of blood and assists in the venous return process.
Why does the abdominal cavity have a soft muscular wall?
The abdominal cavity has a soft muscular wall to provide flexibility and movement during activities like breathing, bending, and twisting. The muscles help protect the internal organs and support the spine and abdomen. This soft muscular wall also allows for the expansion and contraction of the abdomen to accommodate changes in internal pressure.
When is the Blood pressure greatest in the arteries?
Blood pressure in the arteries is greatest during systole. Systole is the period of heart contraction, while diastole is the period of heart relaxation.
What part of blood pressure denotes the force exerted on the arterial walls during cardiac contraction?
The force exerted on the arterial walls during cardiac contraction is systolic blood pressure. In contrast, diastolic blood pressure is the force exerted during cardiac relaxation.
What causes a pressure chage in the chest cavity during breathing?
The movement of the rib cage changes the air pressure in the chest cavity depending on the physical activity the person is performing. If they are running, the air pressure will be constantly increasing and decreasing, leading to stress on the rib cage.
What happens to the volume of blood in the ventricle during the period of isovolumetric contraction?
Both ventricular contraction and atrial diastole take place.
What research has been done on yoga?
The Relaxation Response, by Harvard cardiologist Herbert Benson, showed that meditation and breathing techniques for relaxation could have the opposite effect of stress, reducing blood pressure and other indicators.
What are the benefits of deep breathing and how can it improve overall well-being?
Deep breathing can help reduce stress, improve focus, and increase relaxation by activating the body's relaxation response. This can lead to lower blood pressure, improved digestion, and better sleep, ultimately enhancing overall well-being.
