Drugs called calcium channel blockers help relax the walls of arteries and veins, thereby lowering the high blood pressure. How does blocking a calcium channel cause the muscles of blood vessels to relax and why? Think, muscle types, where are they found, calcium in the contraction, etc.

What physiological reaction happens to the body with the “fight or flight” response? Increase heart rate. Constricted pupils Decreased blood pressure D. Decreased heart rate

Label the following as A, B, C, D, E, F, G: -Ventral Blood Vessel -Longitudinal Muscle -Dorsal Blood Vessel -Setae -Ventral Nerve Cord -Typhlosole -Circular Muscles

Cycling is a form of exercise known to increase the heart rate. For cycling, four incline levels typically determine how much more intense you would like the workout to be. Level one is a walking pace, two is slightly more difficult, three is like cycling up a hill, and four is the most intense like cycling up a mountain. I will test the heart rate to see how it increases or decreases depending on each incline level. The moderate activity would be levels one and two, while the strenuous activity would be levels three and four. Before beginning the exercise, I will sit on the bike in a resting position to get my resting heart rate.  Then I will start the stopwatch on the bike that records my cycling time, heart rate, and RPM (revolutions per minute). I will start at level one for five minutes and then record my heart rate after the session.  I will rest for five minutes and then repeat the same process for each incline level (three more times; four in total).   What may be the…

What stimulates Golgi tendon organs?   A muscle is contracting with minimal tension.   A muscle is stretched nearly to its limit.   A muscle has become metabolically active.   A muscle starts to relax after strenuous exercise.

Explain how our muscular and skeletal systems function in a flight and fight situation , include the specific organs, cells, tissues, molecules and process involved

Joe is a 65-year-old man. Two years ago, Joe was driving home from the golf course when he had a heart attack. Joe's car struck a tree head-on, and he broke his left leg in the accident. Today, Joe's leg has completely healed. However, his heart is not as strong as it was prior to the accident. Which one of the following statements best explains this situation? A. Bone tissue is repaired with lots of fibrosis; cardiac muscle has very little collagen. B. Only epithelial tissues and bone can regenerate;all other tissues are repaired with only fibrosis. C. None of these is relevant to the situation. D. Bone is good at regeneration; cardiac muscle has very little or no ability to regenerate. E. When bone tissue is damaged, there is no inflammation; cardiac muscle has lots of inflammation.

Why is so little ATP stored in the muscle cells? High levels of ATP would get broken down quickly resulting in the muscle cell overheating. ATP is a heavy molecule. ATP regeneration requires very little energy. The cell does not need much ATP to function.

= On Ligaments have what fiber type and why? Connective Tissue: Loose and Dense Tissue Fibers (Short answer questions): Contrast the functions of and dense connective tissue. Which loose connective tissue type might lead to obesity and why? Why do athletes get tears in ligaments and tendons? Contrast the operation of regular vs. irregular dense connective tissue. Connective Tissue: Supportive Tissue Match the cartilage type with where it can be found in the body: Hyaline disks in the vertebral column Fibrocartilage earlobes MacBook Pro
