The literature on the creative personality is curiously equivocal in its characterization of the traits supposedly possessed by eminent creators.
The muscular system is made up of tissues that work with the skeletal system to control movement of the body. Some musclesâlike the ones in your arms and legsâare voluntary, meaning that you decide when to move them. Other muscles, like the ones in your stomach, heart, intestines and other organs, are involuntary.This means that they are controlled automatically by the nervous system and hormonesâyou often don't even realize they're at work. The body is made up of three types of muscle tissue: skeletal, smooth and cardiac.he digestive system is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair.
Anaerobic exercise consists of brief intense bursts of physical activity, such as weightlifting and sprints, where oxygen demand surpasses oxygen supply. While aerobic exercise relies on oxygen, anaerobic exercise is fueled by energy stored in your muscles through a process called glycolysis. Glycolysis is a method by which glycogen is broken down into glucose, also known as 'sugar' and is converted into energy. Glycolysis occurs in muscle cells during anaerobic exercise without the use of oxygen in order to produce energy quickly, thus producing lactic acid, which causes your muscles to fatigue. Lactic acid is a by-product of glycolysis and forms when your body breaks down glucose for energy when oxygen is low.
