cardiovascular

what i done to test my cardiovascular system was by standing in a spot doing as many star jumps as i can within one minute, after i done the test i would then sit on a chair and get either the teacher or a student to test my pulse rate on a pulse machine. i tested my pulse rate before i done the activity to see if there was a diffrence which there was, my pulse rate before was 52 beats in a minute, after i done the activity my pulse rate changed with quite a big diffrence which was 116 beat a minute.
this activity shown me that the slightest bit of excersise can change your pulse rate very fast.



long term affects of exercise

doing exercise and doing it for a long term can be very healthy and good for you and your body, doing exercise doesnt only just build up your muscles but can also make your heart stronger than what it is already, if you do exercise and do it on a regular basis can make you very fit and healthy therefore you wouldnt get ill as easy as those that dont exercise on a regular basis but then again doing long term exercise and doing too much of it can cause you heart failure therefore you may well get a heart attack, basically where if your training or exercising too much your body wont be able to rest enough therefore it could cause blood failure and heart failure, which means half of your body will be working and the other side wont, for an example fabrice muamba the footballer, he trained too much which caused him to have a heart attack and what happened was, where your heart beats both sides fabrice muamba only one side of his heart was beating for then which caused him to have a unfortunate heart attack.



Musculuskeletal 

A musculoskeletal system also known as the locomotor system is an organ system that gives animals including humans the ability to move using the muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body.
It is made up of the body's bones the skeleton, muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system's primary functions include supporting the body, allowing motion, and protecting vital organs. The skeletal portion of the system serves as the main storage system for calcium and phosphorus and contains critical components of the hematopoietic system.


Short term affects of exercise 

 One of the short-term effects of exercise is an increase in your heart rate. Actually, your heart rate will begin to rise before you even start to exercise. Your brain realizes you are going to work out and releases adrenaline to speed up your heart in preparation for the upcoming exertion. This is called "the anticipatory response." Heart rate will continue to rise in direct proportion to the intensity of exercise until maximum heart rate is achieved.  

Respiratory

The respiratory system  is the biological system of an organism that introduces respiratory gases to the interior and performs gas exchange. in humans and different mamals the anatomical features of the respiratory system include airways like lungs and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by something you call diffusion  between the gaseous external environment and the blood. This exchange process occurs in the alveolar region of the lungs. Other animals, such as insects, have respiratory systems with very simple anatomical features, and in amphibians even the skin plays a vital role in gas exchange. Plants also have respiratory systems but the directionality of gas exchange can be opposite to that in animals. The respiratory system in plants also includes anatomical features such as holes on the undersides of leaves known as stomata.
