increases the heart rate. ---- Increases the force of contraction, and therefore, the amount of blood pumped out at a time. Think of a rubber band...the more you stretch it, the harder it contracts when you let go.

An increased concentration of glucocorticoids in the blood will?
An increased concentration of glucocorticoids in the blood can lead to effects such as increased blood sugar levels, suppression of the immune system, and reduced inflammation. Chronic elevations of glucocorticoids can also have negative impacts on mental health and lead to conditions like Cushing's syndrome.
How does increased blood flow helps muscle cells release more energy?
Increased blood flow helps muscle cells release more energy. This is because the blood delivers the products needed for the cell to function.
When a person is exercising the body needs to deliver increased amounts of oxygen to the muscle' which component of blood ensures that the muscle's will receive it?
Hemoglobin in the red blood cells.
Why does walking prevent stagnation of blood in the legs?
The venous circulation of the legs requires muscle contractions to assist with blood return. Walking helps provide this muscle contraction.
Function of coronary sinus?
To return deoxygenated blood from the heart muscle to the right atrium.
What happens when you flex your muscle?
The muscle in your arm contracts. The muscle on the other side of your arm, opposite from the side that you are flexing, stretches.
What is adrenoline?
Adrenaline, also known as epinephrine, is a hormone made in the adrenal glands (on top of the kidneys). Once released into the blood, adrenaline travels throughout the body and causes increased heart rate, increased blood pressure, decrease blood flow to the stomach and intestines, increased blood flow to skeletal muscle, dilation of the pupil, and increased alertness.
How increased blood flow helps muscle cells release more energy?
because person gets tired
What would happen if salt content of blood increases?
When the salt concentration in your blood rises, water is pulled from your Intracellular Fluid (ICF) into the blood or Extracellular Fluid (ECF). Increased fluids in the blood vessels stretches the blood vessels and causes increased Blood Pressure (BP). Increased BP induces a complicated protein cascade that leads to more salt and subsequently water being secreted from your kidneys. Secreting more water causes you to become dehydrated as your ICF and ECF re-equilibrate.
What is the most important factor is helping blood return to the heart through the venous system?
Skeletal muscle pump
Do lean people heal faster than overweight people?
It depends more on how active a person is than their actual weight. More activity causes increased blood flow carrying nutrients, oxygen and white blood cells to injuries increasing healing speed and efficiency. An overweight person may have less blood flow because of excess fat and lower activity which could effect healing. A person weighing more due to increased muscle would also have increased blood supply to these muscle tissues which would also cause increased healing.
What are two events occurring in the body that aids in venous return?
Skeletal muscle contractions which pulls the blood back and valves which close after blood has passed through it.
