Science; Overview of Medical Science

The four things I've learned from medical science are about how muscle movement in the arms as muscles relaxed and contract depending on the movement.  muscles are made out of elastic-like tissue. each different muscle has over thousands or even, tens of thousands of small muscle fibers. each individual muscle fiber is about forty millimeters long. It consists of tiny strands of fibrils
we also learned about biceps and triceps and how they work together to get your legs to move.

How the bones joints between them they have this type of liquid called synovial fluid to stop them rubbing together and to stop it wearing away at the bone. I also found out that bones are a living growing tissue collagen is a protein that provides a soft framework, also calcium phosphate is a type of mineral that adds strength and harden the framework of the bone. this is a combination of collagen and calcium that make the bone strong and flexible enough to withstand our stress.

The heart is a muscular organ in most living animals, which pumps blood through the blood vessels of the circulatory system. The left side of your heart has a thicker wall than your right side because it needs to pump blood further away from your heart than the right side. the right sides pump blood to the lungs that are not far away.

The blood has many different things in it like plasma, red blood cells, white blood cells, and platelets. White blood cells help fight off infections. Red blood cells carry oxygen and carry blood around your body. Plasma transports carbondixoide from your cells to your lungs. It also carries nutrients from the small intestine to your cells, also sending chemical messages called hormones to your cells.
