Cardiovascular System's Response to Exercise

The Sympathetic Nervous System is controlled by the

• Somatic Nervous System

• Central Nervous System

• Medula Oblongata

• Cerebellum

The Autonomic Nervous System is controlled in the medulla oblongata. You can Categorize the autonomic Nervous system, in two parts. What are they?

The _________ slows things such as your HR and breathing down

• Medula Oblongata

• Sympathetic Nervous System

• Cardiac Control Center

• Parasympathetic Nervous System

The Sympathetic Nervous System controls heart rate by releasing which hormones

• epinephrin

• Norepinephrine

• Oxytocin

• ATP

The more common name for epinephrin is:

• Glucose

• Cortisol

• Energy

• Adrenaline

The redistribution of blood flow from one area of the body to another, is controlled by the _________.

• Cardiac Control System

• Gravity

• Blood Pooling

• Vascular Shunt Mechanism

At rest about 80% of our blood supply goes to our skeletal muscles.

• True

• False

Which blood vessels have valves?

Gas exchange happens in the ________.

• Veins

• Arteries

• Capillaries

• Venules & Arterioles

Blood flow into the capillary bed is controlled by pre-capillary sphincters at the entrance to the capillary bed: They can constrict, limiting blood flow and they can dilate, maximizing blood flow.

Question:

At rest arterioles to the organs vasodilate, increasing blood flow to the organs, while arterioles to the skeletal muscles vasoconstrict.

• True

• False
