Muscular system

Image
The function of the muscular system is to allow you to move.It also lets your bones move. The organs are the three muscle types, the Visceral muscle, the cardiac, and skeletal muscle. The smooth muscle (visceral) is found inside of organs like the stomach, intestines, and blood vessels. The cardiac muscle is found only in the heart, and it is responsible for pumping blood throughout the body. And last the skeletal muscle, it is the only muscle that is controlled consciously. Every physical action that a person performs (e.g. speaking, walking, or writing) requires skeletal muscle. Most skeletal muscles are attached to two bones across a joint, so the muscle serves to move parts of those bones closer to each other. Interactions : The muscular system works with the nervous system, that makes sense since you usually have to think before you can move. the neurons of the nervous system are connected to most of the cells in your muscular system. So when you think to move s...

Stars, Galaxies, and the Planets - 5/20/18

Image
Summary:  Galaxies come in three different forms, spiral, elliptical, and irregular. Spiral galaxies have a distinct winding or twisting shape. The Milky Way galaxy (above) is an example of a spiral galaxy. Elliptical galaxies have more of a spherical shape and look similar to circles. Irregular galaxies look unique compared to spiral and elliptical galaxies, hence their name. Irregular galaxies appear misshapen and lack a distinguishable form because they are within the gravitational influence of other galaxies close by. During nuclear fusion, four hydrogen atoms fuse into one helium atom. This makes hydrogen the most common chemical element in stars. When the core of a star starts losing Hydrogen, the star begins to collapse. Black holes form from the collapse in the core of a supernova. S&EP: Analyzing Data:  I used tables to display and analyze data on different planets, noticing the differences and similarities between them. I no...

Skeletal System

Image
Function : The Skeletal System allows your body to move, provides structure, produces blood in the bone marrow, and protects your organs. The organs in the skeletal system are the bones, ligaments and joints, tendons, cartilage, pivot hinge, gliding joints and ball and socket joints. The function of the bones are not only to provide support and protection to the viscera (with the help of muscles attached to them) but also produces blood cells for the body from the bone-marrow. The function of the ligament and joints is to allow the bone to move in a particular direction and hence enhances the movement of body parts in desired direction. The tendons job is to join the muscles to the bones, hence they are more flexible so as to provide greater range of movement. Cartilage not only plays a role in maintaining and forming the shape of human ear and nose as well as other organs, but also protects the bones against friction forces, or else the bones would corrode easily. The pivot join...
