Circulatory System
These vessels go away from the heart and carry oxygenated blood.
Arteries
This type of exercise is characterized by sprinting/anaerobic work where the heart rate generally stays around 180-200 bpm.
Maximal Exercise
How much water does the standard horse drink a day?
5-12 gallons
Once a horse is infected with this virus it will have it for life and must either live in confinement or be euthanized.
EIA
The walls of these vessels are very thin to allow for easy diffusion.
Capillaries
This type of exercise is characterized by endurance/aerobic work where the heart rate generally stays under 150 bpm.
Submaximal Exercise
What percentage of the body’s total mass does water make up?
60%
Anhidrosis is characterized by the inability to produce what?
Sweat
This very strong blood vessel where blood exits the heart must be able to withstand very high pressures of blood flow.
Aorta
Name the crisis state where the horse is exercised too often at too high demand without enough recovery time.
Overtraining
What happens to blood when there isn’t enough water in the horse’s system?
It gets thicker & cannot move through the body as easily
Anything that results in blood loss, destruction of RBCs or failure to make new RBCs is a main cause of this condition.
Anemia
This side of the horse’s heart is larger because it sends blood to the body so it needs larger amounts of blood.
Left Side
If a horse is not given enough recovery time, meaning glycogen stores have not recouped, muscles will instead try to metabolize what macromolecule?
Proteins
Name two dehydration tests.
Skin Pinch & Capillary Refill
What is the cell volume percentage that is considered anemic?
Below 30%
Resting heart rate of an average horse is…
30-45 bpm
Name the process that becomes more efficient with conditioning where blood is pulled away from organs to the muscles during exercise.
Organ Perfusion
What internal conditions remove the stimulus to drink making it so the horse doesn’t realize it’s dehydrated?
Low Water AND Low Electrolytes
Giving a horse beer often helps with this condition.
